Yes I know alcohol can cause bad lows in SOME people. Not me. Over the last few years, I've noticed that despite having a few rum/diet coke (0g carb), my sugar stays level before I go to bed, then I wake up high, unless I substantially increase my insulin dose. No other foods, I'm 100% certain there are ZERO grams carbohydrates in my drinks, as I never see a rise until much later.
Why am I certain of insulin resistance? If I don't have any alcohol, I can have a snack before bed, take insulin, I wake up fine. But, if I have 3-4 rums, if I take insulin for snacks the insulin seems to have no effect. This was not always the case, I've only noticed this in the last six months or so....I've been diabetic 22 years now.
I can't seem to find much info on this, only a study targeting T2 diabetics - although the info was useful:
The mechanism involved in the causal relationship between excess alcohol consumption and diabetes may, in part, be related to insulin resistance.Two novel metabolites of alcohol, 2,3-butanediol and 1,2-propanediol, in serum concentrations found in people who consume alcohol to excess have been shown to inhibit insulin action on adipocytes in vitro. This suggests that excessive alcohol intake reduces insulin sensitivity, thereby increasing insulin resistance.
Has ANYBODY found this to be true? A few drinks on Friday night is what I look forward to at my job working with idiots! I've already decided to cut it off for the most part, but want to find out if others have found things like whisky/vodka/rum, 0g carbs, (yes I know SOME flavoured rums have carbs, check out this link http://www.peidiabetes.pe.ca/Documents/Alcohol_Diabetes.pdf ) increase their overnight blood sugars.
