pleased precariously

I haven’t been back on the bike since I was diagnosed. I’ve been to a couple of gentle yoga classes, just to see how exercise affects things. Also, while in Madrid all last week, I must have averaged about 4 miles walked per day.

Still, wasn’t exactly expecting what just happened.  Glad I did this little test here at home with the bike on the trainer.

at 3pm BG was at 102. ate an apple (~15g).

at 4:14pm BG was at 127. ate another apple (~15g). I wanted to be a little higher than 127 since I was expecting a slight drop in BG.

at 4:30 started cycling.

at 4:45pm, BG was at 90. ate half a honey packet (~15g). kept cycling.

at 5:02pm, BG was at 67. ate the remaining honey (~15g). stopped cycling, and ate another apple (~15g).

Note that I wasn’t even pushing. My heartrate during the 30 minute spin session was in 130-140 range (zone 2 for me).

This is of course entirely due to the long acting insulin I have sitting in my bloodstream. I’ve been injecting 14U lantus every night. Going to try reducing that to 12 (or maybe even 10) tomorrow night with another stint on the bike on Thursday.

This is one of the major advantages of using a pump over a 1 time injection of long acting insulin. The pump simulates the over-time release of a long acting insulin by many small injections of fast acting insulin throughout the day. So if you’re going to exercise, you just dial down this rate/amount, and the change is reflected almost instantaneously.

Anyhow, tomorrow I’m off to PCRC at UCSF to get screened for a diabetes research trial. It should be fun, except for the fact that I’m not allowed to eat anything after 10pm tonight, and can’t have coffee in the morning yay for MMTT.

Update: yay, 5:30pm BG is at 136.
