Better than Expected: My Season in a Nutshell

500+ but no DNF – Ironman 70.3 Muskoka

Editor’s note: Somehow I managed not to post this almost a month and a half ago. Oops! I present it with minimal additional editing. What can I tell you about Sunday’s Ironman 70.3 Muskoka in Ontario? [That's Sunday July 10th.] … Continue reading

Step 9: Communicate more with my diabetes team. Thanks to my health network’s patient portal, I’m in closer contact with Awesome Endo and Awesome NP than ever before. This option isn’t exactly new, but I haven’t made much use of … Continue reading

Step 8

Step 8: Record the data. That should actually say, “Record and act on the data.” I’ve been recording all of my diabetes data—fingerstick BGs, CGM values, carb consumption, insulin delivery, exercise details, infusion set changes, etc.—for the better part of … Continue reading

Step 7

Step 7: Get believable basal rates and carb ratios. They have a huge impact on how my day plays out, but it’s been a while since I verified these basic settings. They’re the baseline for changes that I need to … Continue reading

Step 6

Step 6: Ask for help. Nobody knows my diabetes experience better than me, but that doesn’t mean I’m the only one with ideas. Other people can help, too, by providing insight into diabetes, information about what’s in the food I … Continue reading

First Thoughts on the Dexcom G5

I’m coming up on the end of my first Dexcom G5 sensor, which is to say six days. (Yes, I’ll be trying to restart it and see how good zombie sensors can be.) So far I’m really pleased. It largely … Continue reading

Step 5

Step 5: Use CGM. Once upon a time I used a continuous glucose monitor, and it was helpful . . . when it worked. It didn’t work often enough for me to trust it, though, so I stopped using it. As a result, … Continue reading

I like pastries. I love pain au chocolat, and I’ve wanted to make my own for a while. Last October, my mother- and father-in-law gave me a stand-mixer. My mom got me some supplies. Lisa got me a couple of … Continue reading

Step 4

Step 4: Tolerate lower blood glucose. 120 mg/dL (6.7 mmol/L) isn’t low. 80 (4.4) isn’t low. Context matters, of course: 120 during exercise is time for action, and 80 before bed means it time for a snack. But right now, … Continue reading

Step 3

Step 2

Step 2: Try harder to know or estimate carbs. Knowing the number of carbs in things makes bolusing decisions (somewhat) easier, so why not do it? Taking the right amount of insulin is a separate issue, so let’s leave that … Continue reading
