Last Thursday, I went in to get set up for a five-day run with a continuous glucose monitor (CGM).

Quick overview – with type one diabetes, the pancreas up and quits producing insulin, because it’s a LAZY SLACKER! Therefore, I take insulin via an insulin pump, which delivers a baseline dose throughout the day, and allows me to program additional insulin when I eat. I check my blood sugar about six times a day to help me keep it within a relatively healthy range.

The CGM is a device that automatically checks your blood sugar every five minutes. It automatically sounds an alert if your sugar goes too high or too low. (Sadly, it can’t be programmed to do the red alert klaxon from Star Trek, but some day…)

It works by measuring the interstitial fluid, as opposed to the blood, so the measurements aren’t quite as precise as the ones from my glucose meter. But it does a great job of showing trends (whether your blood sugar is climbing or falling or just chilling and hanging out). It also produces a graph to let you see what your blood sugar is doing over time.

I was hooked up with a Dexcom CGM, which involves a tiny flexible needle that goes into the side of the belly and is hooked up to what may or may not be a T-800 chip from Cyberdyne Systems. This made me a little nervous, since I’ve already got the catheter from my insulin pump stuck to one side of my belly, and the CGM is a little bulkier, as you can see here.

Me: Time to change the insulin pump again.


Me: Peels sticker and catheter off of my belly, removes vial from pump, sets the pump, vial, and tubing on the bed.


Me: Fills new vial.

Taz: Excuse me, human, but the snake appears to have bitten my face.

Me: Removes sticker from Taz’s face.

Taz: Ooh, this looks like an expensive piece of medical equipment. But you know what it’s missing? A CATBUTT-PRINT!

Me: Removes Taz from my insulin pump.

Taz: You appear to be getting ready to jab a needle into your belly. I shall assist by RUBBING MY FACE ON YOUR ELBOW!

Me: Thank you. Pulls out new tubing and prepares to hook it up.


Me: Dork.

Taz: Runs away for no particular reason.

I've spent the past day and a half with a stomach bug, which made me once again contemplate the possibility of installing Mira Grant-style sanitizing showers and blood screening tests in my house.

I've talked before about how I need to regularly test my blood sugar in order to keep my diabetes more-or-less controlled. Well, when I get sick, I have to test even more often. Here's why:

The vertical axis is my blood sugar readings, and the horizontal shows each blood sugar test throughout the course of two days or so.

It would be one thing if getting sick messed up my blood sugar in a consistent and predictable way. If I knew I'd always run high when I got sick, I could adjust the insulin pump to give me a little more insulin during that time.

But as you can see, I was all over the map for the past 24 hours, with a low of 23 and a high of 468.

Not cool, diabetes fairy. Not cool at all.

The low was the most dangerous. Normal blood sugar should be around 100 or so. I was still up and walking around at 23, but had it dropped any lower, I would have been in trouble.

Here's a fun scenario. You have a low blood sugar, which is normally treated with juice or other high-carb food and drink. But your stomach is too messed-up to keep anything down. What do you do?

Well, there are pills to help suppress nausea, which I completely forgot about because my blood sugar was 23 and my head was a bit fuzzy. So I ate high-carb, quick-acting snacks, disconnected my insulin pump for about six hours, and hoped I'd absorb some of the glucose a form rejection to my food.

I'm not thrilled about hitting 468, either. This happened after I finally got to sleep, but because I was sleeping, I couldn't check my blood sugar as frequently. Oops. As much as I needed the rest, in hindsight, it might have been good to set an alarm for one or two in the morning, just to roll over and check my blood.

Short version: Diabetes + Another Illness = Visit from the Blood Sugar Gremlin.

(Also, I'm using this as my excuse for not answering email over the past few days. Sorry about that!)

On October 31, it will be fourteen years since I went to Sparrow Hospital in Lansing and was officially diagnosed with type 1 diabetes. (Tip: Halloween is a crappy day to become a diabetic.)

I’ve talked about the disease before, because yay education and knowledge! Those entries are available by clicking on the diabetes tag.

I thought it would be interesting to try to figure out some numbers as of the fourteenth anniversary of my pancreas calling it quits. As of 10/31/2012…

  • I will have tested my blood sugar approximately 28,000 times. (That’s 2800 times per finger.)
  • By the time I switched to the insulin pump in 2006, I had taken about 15,000 injections.
  • On the pump, I’ve switched sites about 840 times, rotating to different spots on my belly, and occasionally the hips.
  • I’ve worked with three different endocrinologists, one of whom I dumped because he was a prick, and one of whom left his practice.
  • The lowest blood sugar I can remember was when I was in grad school, not too long after the diagnosis. I was walking to a class and started feeling really fuzzy. By the time I got back and tested, my blood sugar was in the 20s. (Normal is around 100, give or take.)
  • The highest was the night before my diagnosis. I went out to dinner with my family, then checked my blood on my dad’s meter to confirm whether I was right about being diabetic. The meter errored out because it couldn’t read that high, which means my blood sugar was above 600.
  • Blood sugar as I write this blog post: 96.
  • I’ve had between 40 and 50 blood draws for labwork. (Most of which have gone very smoothly. Props to the Sparrow Lab on Pennsylvania.)
  • Best guess as to the total cost of medicine and equipment to keep me alive these past 14 years: $86,000.
    • $33,000 (test strips)
    • $8000 (lancets)
    • $18,000 (insulin)
    • $1000 (syringes)
    • $16,000 (insulin pump sets)
    • $10,000 (insulin pumps - 2)
  • Cost of the initial hospitalization, visits to the endocrinologist, pump education, and dietician, and miscellaneous labwork: I have no freaking idea. Let’s just call it “a lot.”
  • Average number of years this disease shaves off of my life expectancy: 5.
    • But screw that. I plan to live forever.
  • Number of additional years of life I’ve gained thanks to a century’s worth of research into insulin and diabetes treatment: 14 and counting.

All of which makes me very grateful to be in a position where I’m able to get reasonably good health insurance, as well as for living at a time when this disease is manageable, as opposed to being a death sentence.

A cure would be nice, and sometimes diabetes is a significant pain in the ass, but given the alternatives, I will happily keep jabbing my fingers and pumping insulin into my belly.

A quick recap for newer blog readers: I’ve had type 1 diabetes for 13+ years, and I blog about it occasionally for several reasons:

  1. Because I know other writers read this, and it makes me cranky when stories get the details of my disease wrong.
  2. I’m comfortable talking about it, and I think helping people understand this stuff is a good thing.

Previous diabetes posts are, shockingly enough, tagged with the diabetes tag.

Anyway, one of the questions I get fairly often is “Doesn’t that hurt?” People asked that more back when I was taking 6-7 injections every day. Now that I’m on the insulin pump, all they see is the fingertip blood tests. But they still ask, and understandably so. Diabetes is a pretty needle-happy disease. (So if you’re needlephobic and don’t want to read about ‘em, this is your cue.)

The answer is … yeah, sometimes. It depends.

Let’s start with a picture I’ll call Jim’s Collection of Stabby Things. On the left is a typical insulin syringe. I keep some around just in case I ever have trouble with the pump.

In the middle is a spring-loaded tool designed to insert the catheter for my insulin pump. That white thing on the end is an adhesive sticker and a metal needle threaded through a teflon (I think) catheter. The spring jabs it into my belly, I pull out the metal needle, and the sticker holds the catheter in place for 2-3 days at a time, allowing the pump to deliver insulin.

I love technology.

On the right is the finger-stabber I use to draw a small drop of blood from my fingertips to test my glucose levels. I’d describe it as essentially painless. I test my blood without thinking, and I can’t remember the last time I noticed any pain. Which is odd, considering that this was the hardest thing for me to do that first time back in 1998. I remember holding that thing for several minutes, sweating as I tried to make myself press the button. These days, I don’t even think about it.

The ones they use for finger checks in the hospital, on the other hand, are the real-world equivalent of a gom jabbar from Dune. They’re one-size-fits-all, designed to pierce cave troll skin. Thankfully, mine’s adjustable, meaning the needle goes just deep enough to draw blood.

Diabetes syringes weren’t usually painful either. The needles are very thin. Every once in a while I’d hit a nerve or a blood vessel, which stung like hell, but that was the exception.

Getting the pump catheter into place … yeah, that hurts sometimes. It’s a slightly longer needle, and the spring shoots it in quickly to prevent the teflon catheter from kinking. I’d say about half the time it goes in with little-to-no pain, maybe 30-40% of the time it stings, and 10-20% of the time I shut the door so the kids don’t hear me swearing.

Beyond that, it’s been a fairly painless disease so far. Every once in a while someone at karate will forget and punch me in the insulin pump site, which isn’t fun, but it’s not crippling pain. More like getting whacked on a cut or bruise. And there are potential complications that could change things for me eventually — nerve damage being a big and nasty one. But considering this disease would kill me in days if I stopped treatment, I think the occasional painful jab to the belly is more than worth it.

I should point out that my experiences aren’t universal. Some people find the fingersticks very painful. (There are meters now that will let you test a blood sample from the forearm, which has fewer nerve endings to irritate.) I have a harder time with the pump than some people. I had to try several different styles before finding one that worked, for the most part, with my body. So take this as Jim’s Diabetes Experience, not The One True Path of Diabetes Pain.

Questions are welcome, as always.

For the most part, my diabetes is under control, and I don’t think about it much from day to day. I check my blood, drink diet instead of regular pop, and swap out the insulin pump every 2-3 days. It’s a serious disease, but doesn’t significantly interfere with my life.

That said, there are some annoyances…

1. Blood. I don’t mind testing my blood sugar, but when I change out the insulin pump, sometimes the site bleeds a tiny bit, and no matter how careful I am, I keep getting tiny smears of blood on my clothes. It happened again last night. I removed the old set and checked to see if that site was bleeding. It wasn’t. So I finished prepping the new infusion set for my pump, looked back, and there was a tiny smear of red on my shirt.

I swear my belly is taunting me. My blood cells are tiny Weeping Angels that only sneak out when I look away.

2. Insurance. This is not my U.S.-health-care-is-busted rant. But dealing with insurance companies can be annoying. Like when I was told they would no longer do 90-day supplies of insulin, and I’d have to go to 30-day supplies instead. Are you thinking I’ll suddenly stop being diabetic after a month, or just that it will be cheaper for you and the pharmacy to do all that paperwork once a month instead of once every three months? Then there was the time they switched providers for my pump supplies without telling me … or without mentioning that I had to call the new provider to give them my info, or else my supplies wouldn’t show up. D’oh!

In each case, I’ve been able to get things straightened out, and I’m grateful to have health coverage at all. That said, it irritates me every time I have to spend time clearing up stupid mistakes and miscommunications, or navigating nonsensical policies.

3. Food Police. One of my biggest peeves is other people deciding what I can and can’t eat. I know it’s usually well-intended, but please don’t. I can eat anything you can; I just need to take the right amount of insulin for it. I eat ice cream and cake and pizza and whatever else I want. I’ve chosen to stop drinking regular pop, and to eliminate a few things from my diet … but that’s my choice.

If you ask me whether I can eat or drink something, that’s great, and I appreciate the consideration. If you decide for me, I get irritated fast. Even when it’s well-intended, like bringing in brownies to work and saying, “I know you can’t have them, so I brought in a rice-cake for you!” I know my disease and my body better than you; I’ll decide what I should and shouldn’t eat.

4. Insulin Pump & Karate. I love having a pump. I’m getting a new one soon, actually. I love that I no longer have to take 6-7 shots per day.

I do not love the fact that I have to clip the thing to my belt in karate, or that I have to warn everyone I practice with not to hit my infusion site, or that the silly thing sometimes slides around my belt, so I have to make sure it hasn’t moved before I roll to the ground or something.


None of these are huge problems, and I’ll certainly take the peeves over the alternatives. But the disease comes with annoyances, even when it’s well-controlled, and since I hadn’t done a diabetes post in a while I figured I’d share.

Questions are very welcome, as always.

I was diagnosed with type 1 diabetes on October 31, 1998.  That’s right, the day I learned my pancreas was a lazy quitter and I’d have to monitor my carb intake for the rest of my life, I got to make my way through a hospital packed full of Halloween candy for the other patients.

My father was diagnosed with the same thing when he was 24 and a half, midway through grad school, so I was familiar with the disease.  In October of ‘98, I was exactly 24 and a half years old, and was just starting my second year of grad school.  (My son is not allowed to go to grad school until he’s 25.)

The symptoms had started a few months earlier.  I started feeling a lot thirstier, and drinking much more.  Milk, water, orange juice … I even tried a few wine coolers.  (This brief period is the only time in my life I drank anything with alcohol.)

The trouble, though I didn’t know it, was diabetic ketoacidosis.  As my pancreas cut down to part time work and prepared for retirement, my blood sugar rose steadily higher, throwing my body’s pH out of whack and causing any number of nasty side effects.  My body kept trying to flush the crap out of my system, and to do that, it needed fluids.

Of course, the fluids I was drinking had a lot of carbs … which means my blood sugar just kept on climbing.  And all that fluid had to go somewhere, meaning I was constantly running to the bathroom, day and night.

In addition to the drink-n-pee cycle, my mood went downhill.  I was teaching freshman English at Eastern Michigan, and I remember ripping into one of my students I thought was disrespecting me.  When my roommate left his dirty dishes in the sink, I did them … swearing and slamming things around hard enough I’m surprised I didn’t break ‘em all.

Mom talks about my father going through the same thing.  She says she was relieved when he was diagnosed, because if he had continued acting that way, she wasn’t sure how much longer she would have put up with him.

I also lost weight.  A lot of weight.  No matter how much I ate, my pancreas wasn’t producing enough insulin to use that food.  I dropped from over 150 pounds down to about 130.  (For comparison, I was about 160 pounds in this picture.  130 on me is not healthy.)

When I finally figured out something wasn’t right, I headed home.  I went out to dinner with my family, then used my father’s glucose meter to check my blood.  Normal blood sugar is about 80-120.  The meter’s range went up to 600.  Mine was too high to read.

Dad said he had already figured out I was diabetic from the amount I drank that night, and how often I went to the bathroom.

The nice thing is that after I went to the hospital, I felt better within a day or two.  Insulin is amazing stuff.  I had no idea just how bad I had been feeling until I was better.

I’ve kept the disease under pretty good control for 12 years now, in no small part because I remember how miserable I was back then, and I have no desire to go through that again.

I’m very comfortable talking about the disease, so questions and comments are more than welcome.  (With the understanding that I’m not a doctor, and I can only talk about my personal experiences.)

For those who are interested, the American Diabetes Association has a list of diabetes warning signs.

My father has had type 1 diabetes for 36 years.  A long time ago, I remember him talking about the disease, saying it was strange to know what would probably kill him.

When your Dad says something like that, it sticks.  When you’re diagnosed with the same disease years later, those words come back again loud and clear.

Of course, these days we’re better off, with five-second glucose tests, insulin pumps, and the first generation of continual glucose monitoring systems (for those with good health coverage and access to such things).  I’ve been able to keep my diabetes under pretty good control for more than a decade.

With the standard disclaimer that I’m not a doctor, I’ve seen what uncontrolled diabetes can do.  I used to play racketball with a man who lost his foot.  My mother donated a kidney to a family friend who was on dialysis.  My father has good control, but has lost a little sensation in the fingertips.

In some ways, I think of diabetes as a video game.  A serious game, but a game nonetheless.  The object is to keep my score (blood sugar) between 70 and 140.  Use food, exercise, and insulin to stay within the bounds (and don’t piss off the diabetes fairy on level six).

When the score dips below 70, I start to get into trouble.  Low blood sugar (hypoglycemia) is an immediate danger.  I sweat and feel shaky.  My brain gets a little fuzzy.  I’ve never been drunk, but I imagine it’s a bit like this, with confusion and loss of coordination, not to mention some mood swings.  If it gets worse, you can have seizures, slip into a coma, and die.

Hypoglycemia can hit fast and hard.  I usually feel when I’m getting low, and can scarf the nearest convenient source of glucose.  (I keep a candy dish on the bedside table.)  But if you go low too often, you can start to lose that awareness, which is both scary and dangerous.

Whereas hypoglycemia hits fast and hard like a barbarian, high blood sugar (hyperglycemia) is the ninja of diabetes.  My blood sugar can creep up to 200 or more without me noticing, because there’s no immediate effect.  But in the long term, the ninja will Mess You Up.

High blood sugar can damage the eyes, kidneys, nerves, heart … it’s nasty.1  Sugar-laden blood cells rip up the tiny blood vessels of the eye.  Nerve damage causes loss of sensation on peripherals, so you might not notice that infected cut on your foot until it spreads.  And diabetics tend to heal slower…

In the meantime, high blood sugar paradoxically means your body isn’t able to use the sugar in your blood, so you begin to rapidly break down fat for energy, releasing toxins into your system. This can lead to a condition called diabetic ketoacidosis.  It’s an effective way to lose weight … if you don’t mind killing yourself.  (I dropped 30 pounds before I was diagnosed.  I don’t want to know how long it took for my system to recover.)

Brief soapbox: I’ve known people who deliberately went off insulin in order to lose weight.  That’s right, we’re so freaking obsessed with weight loss that poisoning killing ourselves is an acceptable way to drop a few pounds.2

High blood sugars don’t generally kill you right away.  If I go to a con and enjoy cheesecake after diner, my sugar might hit 250 a few hours later.  But I test often at cons, allowing me to bring it down pretty quickly. My HBA1C, a long-term average measure of blood sugar, usually comes back around 6.0 (upper normal).  Even though I have the occasional spike, my overall control is pretty darn good.

Perfect control isn’t possible yet, but I don’t plan to let this thing kill me.  Taking care of the disease is a pain in the ass, but it’s far, far better than the alternative.

Comments and questions are welcome, as always.

  1. And for some reason, if I’m too high, I start to get pimples.  Damn pimple ninjas.
  2. It was pointed out that ketones aren’t actually a toxin, but that they mess up the body’s pH and cause a number of other nasty side effects.

People often make assumptions about what I can and can’t eat as a type 1 diabetic.  Here’s the thing: I can eat anything I choose … as long as I take the correct dose of insulin to go with it.  Therein lies the trick.

Diabetes Math 100: Introduction to D-Math

I try to keep my blood sugar goal between 70 and 140.  I’ve discovered that one unit of insulin drops my blood sugar about 60 points, so if my blood sugar is 200, I’ll program the insulin pump to give me 1.5 units.

With meals, you’re worried about glucose.  This means you primarily count carbohydrates.  I need to take about 1 unit for every 8-9 grams of carbs.

Pop Quiz: My blood sugar is 160, and I’m sitting down to a meal with 90 grams of carbohydrates.  How much insulin do I take?

I’ve also found that I need more insulin for my first meal of the day.  Closer to 1 unit for every 7 grams of carbs.  A 50 gram breakfast gets about 7 units.  So now there are two ratios to remember.  So far, so good.

Diabetes Math 200: Graphing Over Time

Those ratios are nice, but some foods are digested and absorbed more quickly than others.  Humalog insulin has a pretty stable absorption rate, peaking after about 90 minutes.  This can be a problem.

A number of factors affect the absorption of that meal you just ate.  Some things, like orange juice, get absorbed pretty darn fast.  Others, like pasta, can take a long time to absorb, especially larger noodles.  (Lasagna is a killer.)

The insulin pump is programmed to deal with this using a feature known as the square bolus.  Basically, you program two doses of insulin: one to be delivered immediately, and a second to be delivered at a steady rate over several hours.

Pizza has a pretty high fat/grease content, which also slows down absorption. So for pizza night, I’ve figured out the proper dose is around 6.5 units now and a square bolus of 10 units over 6 hours.  Lasagna is 2 units now, 6-7 over about 5 hours.  A piece of fruit?  1 unit now, no square bolus.

Diabetes Math 300: Multivariable Equations

Now things get exciting.  Remember those ratios we learned back in the 100-level class?  They don’t actually stay the same from day to day.  Here are some of the factors that can mess with your numbers:

  • A good aerobic workout speeds up my metabolism and decreases my insulin requirements by 10% or so for up to 24 hours.
  • Getting sick throws everything off, and usually raises my blood sugar, meaning I need 10-20% more insulin.1
  • Stress tends to raise blood sugar, though I’m told it can also lower it in some people with type 1 diabetes.
  • When did I change my insulin pump?  If it’s the first 24 hours of a new set, the insulin absorbs better than it does on the second day.
  • The insulin pump uses catheters that go into the belly fat, and occasionally those sites get irritated or build up scar tissue, which slows absorption.  Increase all dosages 5-10%.
  • Finally, there’s the “heck if I know” factor.  Because sometimes your blood sugar still ends up at 250, even though you ate the exact same thing for lunch, took the exactly right dosage of insulin, and did everything else you were supposed to.

Conclusion: It’s not that diabetics can’t eat certain food.  But I’ve chosen to eliminate some things from my diet.  I drink diet pop instead of regular; I don’t usually drink milk; I’ll eat ice cream, but rarely.  Not because I can’t, but because eliminating those things from my diet reduces the number of variables and makes it easier for me to calculate my dosage.  Even so, those calculations are often a best-guess, and I’ll usually check my sugar 2 hours after a meal and adjust for any errors.

That’s how it works for me as a type 1 diabetic.  Questions are welcome, as always — I’m pretty open about this stuff.

  1. I can often tell I’m getting sick because my blood sugar starts to spike a day or so before any other symptoms.

From this week’s episode of Criminal Minds, “The Uncanny Valley”:

“Diabetics metabolize everything they consume differently.  Food, drink, drugs … it all gets broken down into blood sugar.”

Ignoring the fact that not all food and drink gets broken into blood sugar (Coke Zero, anyone?), you’re telling me my drugs all turn into blood sugar too?  Guess I’d better start taking insulin with my cholesterol pills from now on.

The show also asserts that diabetics can metabolize drugs faster, and thus our victim could shake off the paralytic.  (Which was being received via an I.V. drip.)  This struck me at first as either poorly researched or poorly explained.

So I spent this morning digging up research so as not to come off as an idiot when I wrote my rant, and what do you know.  I came across a 2007 study from The National Institute of Diabetes and Digestive and Kidney Diseases which states:

In fact, type 1 diabetes not only leads to activation of drug metabolic genes, but also has a profound effect on the metabolism of certain drugs. Mice with induced type 1 diabetes rapidly clear their systems of a compound that induces temporary paralysis, while normal mice cannot.

From that same article, “Controlling the diabetes reversed the effect: when insulin was given to the mice, the CAR-induced genes turned off. “  So in theory, since this woman was off her insulin, there might have been a window where she would have thrown off the effects of the drugs before falling into a diabetic coma.

I’m not finding anything to support the idea that drugs all break down into blood sugar, though.  That one still strikes me as goblin dung.  According to the article above, a diabetic with out-of-control glucose doesn’t clear the drug by breaking it down into sugar, but because (in mice, at least) this activates certain genes that clear the drug from the system.

So, I’m cranky about the “Everything turns into sugar” bit, but it looks like they did the research on the rest.  Thanks for that, Criminal Minds — the widespread laziness and misinformation spread in most books and shows when it comes to diabetes is a huge peeve of mine.

On that note, if any of my writer friends are ever doing a story that includes diabetes and have questions, please don’t hesitate to ask.  I’m not a doctor, but I can give you the basics and tell you what it’s like to live with the damn disease.

Also, I think I have a man-crush on Dr. Reid.

• Book signing tonight at 7:00 at Nicola’s Books in Ann Arbor.  I’m sacrificing a tribble to the weather gods for a blizzard-free signing this time!

• This is why I shouldn’t be allowed to play with Photoshop.  I end up making LJ icons and escalating the plotbunny wars.  (Help yourself to the icon, if you’re interested.)


I realized that after five diabetes posts, I had yet to talk about the basics of the disease.  Remember I’m not a doctor – everything that follows is based on my personal experiences and understanding.

For you non-diabetics out there, it works like so.  You eat food.  Your body breaks the food down into, among other things, glucose in your blood.  Your pancreas secretes a hormone called insulin that allows you to use that glucose for energy and keeps the glucose in your blood at a normal, healthy level (around 100 mg/dl).

There are two types of diabetes (three if you include gestational).  Type two is the most common.  Your body makes too little insulin, or else your cells aren’t able to use it efficiently.  A lower-carb diet can help, as do exercise and weight loss (your body might not produce enough insulin for 250 pounds, but could have enough for 175). There are meds that improve insulin absorption.   In some cases, you also inject insulin to supplement what your body makes.

I’ve got type one diabetes, which means my pancreas is a lazy bastard that quit producing insulin altogether.  Stupid pancreas.  For me, the treatment is black and white: I either take insulin or else my blood sugar rises until I go into a coma and die.  Type one is known as juvenile diabetes, giving folks the false impression that I got it as a child.  (I was 24 when I was diagnosed. My blood sugar was over 600 mg/dl.)

I started with injections, taking a long-acting insulin shot to manage my baseline needs and short-acting insulin at meals.  Because of the way I eat and live, I was taking 6 or 7 shots a day to keep things under control.  So I switched to an insulin pump, which gives me a baseline insulin rate throughout the day and allows me to give myself more at the press of a button.

When I eat, I guesstimate the amount of glucose I’ll be getting from that meal and take insulin to match.  I check my blood sugar levels about two hours after each meal.  Too high, I take more insulin.  Too low, I snack.  (If you see me acting drunk and confused, shove some carbs my way.)

What this means, among other things, is I can eat whatever the heck I want, as long as I take the insulin to cover it. I get cranky when people tell me what I can and can’t eat.  Yes, I had a donut yesterday.  I also took more insulin and checked my blood sugar an extra time.

I do adjust my diet somewhat to keep things manageable.  For example, I switched to diet pop because diet has zero carbs, meaning I can drink it without worrying about taking insulin.  On the other hand, when I was first diagnosed, I did extensive “research” to figure out exactly how much insulin I needed to cover a hot fudge sundae (2.5 to 3 units of regular insulin plus 1 unit of long-acting). So when you ask what I’m allowed to eat, the answer is anything I want, so long as I’m keeping the disease under control.

I was going to get into the consequences when the disease gets out of control, but this is getting long, so I think I’ll save that for next time.

I’m very open about all this, so feel free to ask questions.  You can also click the “diabetes” tag if you want to read any of my earlier posts about the disease.

Last night I spent two hours at karate.  (Got my promotion form for 3rd brown belt — woo hoo!)  It was a good workout, but the class only meets once a week, so I’ve started trying to ride the exercise bike a few times a week too.

There are a few reasons for this.  My day job is very sedentary.  I spend all day sitting at a desk answering questions, and then I come home and sit at a different desk and try to catch up on writing-related work.  (If you’re going to do the writing thing, it’s a good idea to do something active, just to keep your body from atrophying altogether.  /Soapbox)

I’m also doing it for my mood.  Yesterday was a craptastic day at work.  Two hours at karate, and I was completely past it.  Today was worse.  A half-hour of pedalling and watching The Daily Show, and I’m in a much better space.

Finally, exercise is good for the diabetes.  The disease heightens the chances of trouble with the majority of your internal organs, so exercise is a good idea to help counteract that.

But there’s a problem.  You see, a good aerobic workout affects your metabolism for 24 hours or more.  In my case, it’s a very noticeable effect, because it means I need less insulin for at least 24 hours after riding the bike.

If I were to get the same amount of exercise every single day, I’d be all set.  I’d just need to adjust my baseline dosage for post-workout mode, and remember to take less insulin at meals.  But because I can’t do this every day, it means I get the joy of trying to manage two baseline rates, as well as calculating two dosage ratios at meals.

Add to this the fact that my insulin needs vary from day to day anyway, depending on stress, exhaustion, activity, the phase of the moon, and Shadowstar only knows what else.  So the exercise throws yet another variable into the mix.  I’m pretty good at estimating my needs, but it’s not an exact science.

The ironic part?  Exercise usually helps you lose weight, right?  Over the past month, as I’ve tried to sort out the new dosages, I’ve probably gained weight because I keep dosing too aggressively for post-exercise mode, which drops my blood sugar, which then requires the prompt application of M&Ms.

It really is a rude disease.  But the exercise has been a good thing overall, both emotionally and physically.  I may need to keep testing more often, but I’ll get this sorted out eventually.  And in the meantime, hey–how often do you get a medically valid excuse to eat chocolate?

Help please!  I need a small device I can use to make the “bleep” sound of censored swearing.  I’m hoping to do a reading of “The Creature in Your Neighborhood” at my book launch next week, but there’s one scene that wouldn’t be appropriate without the bleeping.  Any ideas on a device that might work?


I debated whether to share this one, but I decided what the heck.  My ego can take it, and everyone can use a laugh on Monday mornings, right?

My insulin pump is a pager-sized device which contains a plastic vial of insulin.  It sends out a low base dose of insulin, and I can program it to deliver more as needed for meals and adjustments.  That vial is connected to a tube, which goes to a small catheter in the belly (or wherever else you stick it.)

Photo from Minimed (this is not Jim’s belly):

I use the 43″ tubing, which gives me plenty of … um … maneuvering room when changing clothes, etc.  Extra tubing gets tucked in, and life is good about 98% of the time.

Last week I had a 2% night.  I was getting changed for bed, and the tubing got tangled with my pants.  I didn’t realize this until it was too late, and the pants/tubing mess was tugging the catheter and sticker on my belly.

I couldn’t straighten up without ripping the catheter out.  (And there’s a sentence you don’t read every day.)  I tried to yank the pants back up, but they were binding my knees, and I started to fall.

Graceful as ever, I turned the fall into a hop.  My other foot came down square on the edge of the laundry basket, wrenching my little toe.  At this point, some primitive self-preservation instinct in my brain screamed Just surrender to the inevitable before you destroy half the bedroom hopping about like a one-legged kangaroo on an LSD trip!

I fell.  There was an earth-shattering kaboom.  My wife rushed out thinking … okay, I don’t know what she was thinking as she saw me sprawled on the floor, pants at the ankles, rugburn on one knee, still doubled over to protect the pump tubing, and clutching my throbbing toe.  I don’t want to know.  At least she was kind enough not to laugh too hard after she saw I was okay.

Grace?  Dignity?  I used to have these things, once upon a time.

This is the sort of thing they don’t warn you about when they’re teaching you how to use your insulin pump.

Sexual Assault Prevention Tips Guaranteed to Work. I absolutely love this piece.


So apparently this is the week to talk about invisible diseases/conditions.  I don’t know how invisible my diabetes is … the insulin pump is kind of obvious, and I don’t try to hide when I’m checking my blood sugar.  On the other hand, it’s not like my pancreas has fallen out in the middle of a convention panel or anything like that.

I’ve chatted about the disease a bit already here and here.  With a doctor’s appointment set up for this afternoon, I got to thinking about the cost of the damn disease.

I’m very fortunate to have good health insurance, which means most of that cost is actually invisible to me.  The insurance is one of the reasons I took my day job, and it’s the biggest reason I’ll likely never be able to quit and write full time.  But recent events got me thinking about how much diabetes would cost if I were ever to get laid off or lose those benefits.

  • Blood sugar test strips (testing 6-7 times/day) : $200/month
  • Lancets for blood tests: $63/month
  • Insulin pump infusion set:  $116/20-day supply
  • Insulin pump reservoirs: $33/20-day supply
  • Insulin (this one is a guess): $100/month

That’s $586.50 per month, and that’s before we get into doctor visits (every 3-4 months), bloodwork (also every 3-4 months), and occasional costs like replacing the insulin pump if it breaks ($1000?) or, if things go really badly, a trip to the hospital.

If I were covering the costs myself, there are changes I could make to save money.  I could test my blood less frequently, switch from the pump back to multiple daily injections, not see my doctor quite as often, reuse lancets and syringes, and so on.

Of course, the more I skimp on the daily care, the more likely I am to end up in the hospital due to complications…

It’s not something I think about very often, but it scares me a bit, and I very much resent that it takes away my option to try to go full-time as a writer.

Like the first Diabetes Details post, I have no idea how many people will be interested in this, but I’m writing it anyway.  A few of you will be happy to know this one has zero needle-related content.

I’ve been using an insulin pump for about six years now.  Basically, the pump is a pager-sized device that provides a constant baseline flow of insulin into a small catheter in my belly.  I can also program an extra dose of insulin when I eat, or if my blood sugar is too high.

The problem comes about because I have to change that catheter every two days.  It’s held in place by a very strong sticker about the size of a Canadian Loonie coin.

Strong adhesive plus belly hair is a bad thing.  I finally got tired of waxing a round spot on my stomach every time I changed the silly thing, and have taken to just shaving the belly.  This is … strange.  But far less painful.

The other interesting (to me) aspect of changing out the pump is brought to you courtesy of my four-year-old.  If he knows I’m going back to switch things out, he’ll follow me and climb up on the bed.  There he’ll wait not-so-patiently for me to finish drawing insulin into the new plastic bottle.

You see the plunger on the end?  That’s how you pull insulin into the plastic bottle.  Once it’s full, the plunger unscrews, and the bottle goes into the pump.  At this point, my job is to attach the plunger to the old, empty bottle, which now becomes the Best Toy in the World, for about 1.2 seconds.  That’s how long it takes to yank the plunger back, creating that wonderful popping sound as he pulls out the bottom of the bottle.

Changing the pump is still a pain in the ass, but the enthusiasm of a four-year-old makes everything less annoying.

This is one of those blog posts where I have no idea if anyone else will be interested, but it’s something I felt like talking about.

I’ve mentioned before that I’ve been diabetic (type 1) for a little over ten years.  My father was diagnosed with the same thing back when I was born, so in a way, I’ve been living with this thing for my whole life.

What fascinated me when I was diagnosed was how much I had never noticed before.  I knew in a vague way what diabetes was and how it could affect you.  I knew about keeping insulin in the fridge and daily shots and blood sugar checks and your spouse shoving Peppermint Patties into your mouth at two in the morning because you miscalculated the dosage for lasagna.

But I didn’t notice the smaller things.

Brenda Novak’s auction for diabetes research will be wrapping up at the end of the month.  Looking at my two items, bidding has reached almost $100.  My thanks to everyone who’s bid so far.

Following mizkit’s lead, I think I’m going to up the ante.  Bidding on the book is currently at $23.  If that crosses the $40 mark, I’ll throw in a signed copy of The Faery Taile Project as well.

I’ve lived with diabetes my whole life.  My father was diagnosed type 1 when I was born.  I was diagnosed about 10 years ago.  I’ve seen how the technology has changed.  From glucose strips that had to be dipped in urine and color-matched for a very rough approximation of your blood sugar levels four hours ago, we now have meters that will take a drop of blood and give you a reading in 5 seconds.  I started out taking 6 or so injections every day.  I now have a pump that gives me more flexibility and only requires me to stab my own gut every other day.  (Though I do have to shave my belly … there’s always a trade-off.)

And compare that to 80 or so years ago, when diabetics had to sterilize their own glass and steel syringes, then sharpen the needle themselves.  And don’t forget to rub cotton along the needle to check for burrs.

It’s still a pain-in-the-ass disease.  I’ve been fortunate, and have so far kept mine under pretty good control.  But it would be awfully nice to cure the damn disease and be done with it.

If you’re interested in my own story, I posted about my diabetes last year, on the 10th anniversary of my diagnosis: Happy Diabetes Day!
