Hi

Hello and welcome to the forum,

Are there any particular questions/issues you would like help with?

What insulin(s) is he on? When you say his blood sugars drop is that without eating or after eating? If after how long after and what might he have eaten?

Sorry for multiple questions but it will help our members answer your questions?

The insulin is humulin m3. Yes they drop without eating, mainly during the night. Or if he's had lunch, possibly noodles then done a bit of physio then out for a walk and libre is checked it goes down fast.

How long has he had diabetes?
Humulin M3 is a mixed insulin, so both long acting (basal) and short acting (bolus) insulin combined.
This insulin usually isn't first choice because it's hard to adjust doses to the food eaten. It can be the best choice because it usually needs only 2 injections a day, on fixed doses. Two different insulins give much more possibilities to adjust doses as needed, but it also means at least 4 injections a day and more calculating.

Does he have learning disabilities making it hard for him to do calculations on food and insulin, or physical disabilities needing a carer to do his insulin doses (or both)?

Is he seeing a hospital team with an endocrinologist and a diabetes specialist nurse for his diabetes or is he being treated by his GP/practice nurse?

Sorry for even more questions!

Is it possible he is lying on the sensor at night? That can produce an artificial “low” due to the sensor being compressed against the arm.

I find my sensor always reads around 1 point below the actual blood result. Therefore before treating any lows or highs it is best to double check with a meter if possible.
