every spring (at least around this time each year) for the past three years my BG's have gone crazy for about a week.
Some background, I am a 15 year Type I, 45 years old, tightly controlled, my last 3 a1c's were 5.8, 6.0. 6.0. I use a pump with Novolog and a Dexcom, eat a paleo/low carb diet (about 50g carbs a day, no grains, dairy or legumes) and average 18-20 units of insulin a day total (basal and bolus). I consider anything over 140 high and anything under 60 low - and spend the majority of my day within those boundaries.
It started again yesterday, my BG's have been in the mid to high 200's without eating anything different (low carb paleo for the past 3 years). My body becomes extremely resistant to insulin, yesterday my daily total was 35 units - nearly double what I normally need and I never went below 200. This morning - still fasting from dinner last night - I am over 250 and have taken more than 6 units of insulin and ran two miles with no change. I feel fine, not sick. I've changed insulin and sites multiple times when this happens and it doesn't help.
If the pattern holds this will happen for the next week and then things will go back to normal - but why? what is going on? Is it some weird allergy that doesn't have any normal symptoms?
Does anyone else have this happen to them?
