Last night I checked my blood sugar before going to sleep. It was 73. I checked my pump and saw I had no active insulin, but fearing a low, I ate a two small pieces of watermelon- just in case.
This morning when my alarm woke me at 4:55am I staggered quietly out of bed and checked my blood sugar before getting ready to run. 228! I assumed that my high waking sugar was a “rebound” from an overnight low. This is known as the Somogyi effect or rebound, and it’s something I suffered from frequently before getting an insulin pump. Normally after an overnight low I feel terrible in the morning and sometimes can barely lift my head. This morning I didn’t feel that bad¸I just felt a little hammered- something I could attribute to three mornings of waking up pre-dawn. (Monday and Tuesday were 3:55 a.m. wake ups).
Other than the Somogyi effect, I couldn’t think of any other explanation for my ridiculously high blood sugar so I took some insulin to get my blood sugar down to normal. And since I’ve had very little success running after nighttime lows, I went back to bed.
At 7:30am I felt fine and went about the usual morning chores . At 8:15am my blood sugar was 238. Frustrated, I bolused again.
A few minutes later I looked at my infusion site. I’ve been placing my infusion sets a little bit toward my back after getting some good advice, once again, from Jerry Nairn on TuDiabetes “Diabetics Who Run Marathons”. Jerry suggested this as a place where the set won’t come out while running.
My site looked more or less fine, but I decided to change it anyway since it had already been a few days. When I detached the set I understood why my blood sugar had been so high even after I bolused. The set had detached and the cannula was out and bent down.
Annoyed, I changed my infusion set and decided to try and lower my blood sugar and my frustration level by running. It was late (9:00am) and very hot and humid, but I decided to run any way. Since my blood sugar was still high I didn’t lower the basal rate on my pump. I stopped to check my blood sugar after 35 minutes. It had dropped to 195. I decided to lower the basal rate to 35% (where I usually run) and continued for another 25 minutes. The heat was unbearable and after an hour and a little under 7 miles, I decided to stop.
When I got home I checked my blood sugar again. It was 160. Not perfect, but better.
