Low blood glucose

I use a CGM and in the early mornings like 3 or 4 AM I get alerts for low blood sugar. Around 50- 53. I used to get up and drink a bit of OJ it now it seems like all I have to do is get up and move around a little and it goes back up to normal. Anybody know what’s up with that. I did lower my meds at night.

  1. Hi . We are not medical experts, so keep that in mind when you get responses here. Any change at all might have affected your morning blood sugar -- the change in medication, any shifts in exercise levels, better quality of sleep. Have you had a chance to talk with your doctor? Here is an article about the "Dawn Phenomena:" https://type2diabetes.com/clinical/morning-high-blood-sugar. It sounds like that might be what you are experiencing. Wishing you the best. - Lori (Team Member)

    1. Thank you


      1. , hello! Just curious, after you get the alert, do you check with a finger prick? If you’re using a CGM like Libre2 or the like, you may be getting a false alarm. These can occur if for example you could be from laying on the sensor for a period of time. This is called a compression low. I get these from side sleeping. It’s really essential to pause and do a finger prick before treating a low. I suspect your lows may not be true lows if they rebound with a small amount of movement. Try checking with the finger poke and see if it is truly a low or a false low. If moving around corrects it, keep doing that but do check to help identify what you are really seeing.

        1. Are you sleeping on your cgm??? Could be compression low
