I get something like this. Usually over a few nights, then it stops. I am T1 of 33 years.
I normally sleep very well. However, the sweats wake me. I am in the practice of testing, and have found I tend to be low.
I have two types of insulin - levemir - background insulin (long acting) and humalog ( quick acting, meal time). I have found that the night time sweats indicate that I need to adjust the background insulin.
Mild sweats do not wake me, but the state of my bedding lets me know that it happened. Testing after that often gives a high sugar reading due to the liver breaking down glycagon. I ignore that reading, and immediately reduce, or consider reducing, the night time background insulin. If the background insulin is correct, then no hypo should happen. Hypos should be the result of misjudging the ration of CHO and fast acting insulin. However, getting the background insulin correct is hard.
Of course, even if the background insulin is correct, it can be thrown out by- stress, overwork, drink and illness.
As a help - I have a luxurious cotton bathrobe that I keep near my bed. Slipping it on helps keep me warm, and drier, and protects the bedding.
I agree about the pump. This country is really mean about issuing them.
I feel that if the condition continues raise it with the diabetic clinic. It would suggest a misalignment of the insulins.
