Basal Testing (again)

Posted on

I did extensive basal testing last Spring.  But a lot has changed in a year.  I became a half marathon runner/triathlete.  I lost weight.  I stopped running (haven’t ran since January).  I stopped taking my birth control pills. I stopped drinking as much Diet Coke.  With all these changes and with hopes to get my blood sugar under better control for possible baby, I decided to do another round of basal testing.  Also, I have started working with Integrated Diabetes Services and they suggested it so it was the push I needed.

Over the last two weeks, I did the following:

  • Morning test-Eat snack before bed then don’t eat until noon the next day.  Testing 2AM, 4AM, 6AM, 8AM, 10AM, 12PM
  • Afternoon test-Eat breakfast by 8AM then no calories, working out, etc until dinner.  Test at 12PM, 2PM, 4PM, 5PM
  • Evening test-Eat lunch by 1PM then no calories, working out, etc until bedtime.  Test at 5PM, 6PM, 8PM, 10PM
  • Overnight test-Eat dinner by 6PM then no calories, working out, etc. until 2AM (or breakfast). Test at 10PM, 12AM, 2AM
  • Note-stop test if BG gets up to 240 or down to 70

On March 14th, I did the morning test.  It turned out to be pretty stable, so I kept my rates the same:

On March 17th, I did the afternoon test. I tried to do the afternoon test on March 16th, but my blood sugar was running too high. My rates ended up being a little too high so I decreased my rate from 0.4 to 0.35 starting at 11AM.

On March 20th, I did the evening test.  I tried to do the evening test on March 18th and 19th but ran into problems, on the 18th I was too high and on the 19th I was too low.  My CGM wasn’t working too well this date but my meter showed my blood sugar staying pretty level.

On March 21st, I did the overnight test.  There was a drop from midnight to 2AM, so I changed my rate from 0.675 at 10PM to 0.6 until midnight.

Overall, I think my basal rates were pretty good but it helps to have the confidence that they are better.  I sometimes don’t trust my bolus wizard because I think my basal rates aren’t good.  Hopefully, this will put more trust in my rates so I can really have good control.  I found out yesterday that my A1C is 6.8.  Normally, I would be ecstatic at that number but since I’m trying for baby, I really want to get my A1C below 6.5.  Hopefully, I am taking the right steps to get there.

  1. Good job with the testing, always such a pain in the ass. My experience was that when fasting, I needed to lower my basals during mid-day, but then the minute I incorporated normal meals again, I was always too high, so I ended up increasing the basals slightly. All this to say, don’t beat yourself up if once you’re eating again, and not fasting, you still need to tweak the basals to work.

    A fellow T1D once said to me, “to your body, insulin is insulin…it’s not basal insulin or bolus insulin, so do whatever your body needs for that time of day, regardless if it conforms to “normal” management guidelines.” (paraphrasing)

      • Exactly. I was all hung up because my basal rates didn’t follow a normal curve of only going up once and then going down. Shortly after dinner I need my basals to go up for a few hours and then come down…so I basically have “two humps” if I were to draw a line of my basal pattern. After she told me that I thought, “suck it!”…and that’s what I do now. =)

  2. How the heck do you do that? My endo asked me to do afternoon basal testing (skip lunch) about two months ago, just for two days – nonconsecutive is fine – and I just “haven’t gotten around to it” yet.
