I'm wondering if any of you typically see significant increases in basal needs over the winter months and, if so, by what percentage?
I am a long term (over 25 years) Type 1 on a pump (using Humalog). In September of 2012, I was using about 23 units of basal each day. Now I'm using about 30 units of basal each day for an increase of about 30% over about a 3 month period.
During this time, I've experienced some really stubborn highs that had me trying temp basal rates of as much as +85% in an attempt to stay in range.
I've also gained about 5 pounds in that time period with no real change in eating that I can associate - I eat very low carb and was very careful with my choices over the holidays.
I probably have a number of factors at play including the weather (it rained 21 straight days here), a foot issue that kept me off my feet for a few weeks in December, and hormones (I've read that decreased levels of estrogen cause insulin resistance)and I am definitely menopausing. I've also been reading a good deal about insulin resistance in Type 1's.
My endo writes it off to the weather and activity level for now. I've renewed my focus on exercise, increasing frequency and duration, with mixed results with my blood glucose so far but it is early on in this renewed effort.
Up until now, if I walked on the treadmill for 30 minutes, I would see an immediate 40 point drop in blood sugar. Now, at 30 minutes, I may see a drop or it may not budge. Being back on track with exercise definitely makes a difference in the stability of my levels as I find it "smooths" things out. For the first time in a very long time for me, over the weekend I had two consecutive nights of flat lines in the 80s overnight. That's enough to keep me motivated.
I'm the type of person that likes to know what the cause is so I can "fix it". That's the part of diabetes that drives me craziest - we can't always isolate the cause.
Any thoughts or experiences that you would be willing to share would be greatly appreciated. Have a great day everyone! :)
