Q:

Why would my BG level go up while I'm sleeping? I have type 1 diabetes.

Patty Bonsignore

A:

The body gets glucose in two main ways: from the food we eat and from the glucose that is made in the liver. The first, and most common, reason blood glucose levels can go up overnight is that there is not enough insulin in the body to help use the glucose coming from the liver. Check your blood glucose at bedtime and in the morning; if you find it consistently goes up overnight, you probably just need more basal insulin at bedtime. A second reason blood glucose levels can go up overnight is that you are having low blood glucose levels in the middle of the night and are not aware of it. If you are having lows and sleeping through them, the body will correct the low by having the liver make more glucose. If your blood glucose pattern is up and down in the morning, then this may be a sign that you are having lows in the middle of the night. The best way to rule out overnight lows is to do some middle of the night checking. Check at bedtime, at 3 am and when you get up. If you find your blood glucose is dipping during the night, it may be that you are having rebound highs in the morning. The third reason people can experience a rise in blood glucose in the morning is due to the “dawn effect.” Stress hormones are released in the early morning hours to help the body wake up. These hormones cause a natural rise in blood glucose in the morning. Checking at 3 am and when waking up should tell you whether this might be happening to you. If you think it is, then talking to your doctor or nurse about how to adjust your insulin overnight should help.

I had gastric bypass surgery and have type 1 diabetes on an insulin pump. My doctors cannot regulate my sugar on the pump. They believe it's because of the surgery and the way I digest food. Does anyone once else have a similar situation? Help!

I am a 41 year old Type I- Diabetic who is 4’11 and weigh 160 lbs. with large boobs (that gives me 15 of those lbs.). I am very active, workout but loves to cook although I am African American I DO NOT eat fried food regularly. My last A1C was 7.2 and my diabetes is well managed however I suffer from Gastroparesis. Are there any of my Diabetics not significantly overweight who had a successful Rou-en-Y surgery?
Over the next month I am planning to have it done and curious of any success stories. Thank you for sharing!

Glucose, not insulin, is made in the liver. What happens is that when you eat, carbohydrates are absorbed from food and are carried to the liver for processing. In the liver, fructose and galactose, the other forms of sugar, are converted into glucose. Some glucose gets sent to the bloodstream while the rest is stored for later energy use and is released as needed. :)

My diabetic educator recomended that I eat a small snack in the evening. Thus preventing the low and stopping the liver from producing extra at night. Hope this helps.

How can a Type 1's liver make more insulin? I thought a typ3 1 cannot make insulin. If my daughter goes low in the middle of the night, she will have a seizure and we end up in the emergency room. Wasn't aware her body could still make insulin? please explain. Or did I misunderstand. Thank you.

Very interesting. I wondered myself how I can get a lower FBS in am. Eat supper at 4 pm by 7 pm snack. Should I hold off longer to snack? On metformin and Glipizide . Thanks

I am type 2 and have found similar morning highs, I am usually awake at 3-3:30 so testing can be done, if this is the case should I eat/drink something(what) before bed or at 3:00 when I test?

I am a Type 2 diabetic and are on oral medications only. I take my meds in the morning and I might take an additional metformin 500mg or glyburide 5mg if I eat a particularly high carb meal at dinner. What I eat the prior day does not seem to correlate with elevated glucose in the morning. I do occasionally am waken by a low blood sugar level in the middle of the night and I keep glucose tablets by my bedside for that purpose. I find it frustrating to have an elevated BG when I have not eaten in 12+ hours.

Your "hang over" symptoms could be caused by sleep apnea. It's not commonly described that way as far as I know, but I think it'd be worth checking it out if you haven't done that. (Body at the wrong temperatue in the evening might also be due to circadian rhythms not synchronized properly after apnea-induced sleep deprivation.)

Thanks for the advice. I'm going to start checking my blood sugar at 3 am and see if it is dipping.

I sometimes have this problem so I guess I just need to start getting up and checking it in the middle of the night. Thanks for all the suggestions on what to look for and how to look for it.
