Hi
@arifkarim, Welcome to this forum !
We are not doctors or nurses so cannot advise you on insulin doses and the like.
What you may wish to do though is avail yourself with information on this site such as about
low carbohydrate diets so that this, for example, could be discussed with her nurse and doctor.
As someone who has been injecting myself with insulin for 51 years I know how important it is that insulin, diet, exercise balance out with blood sugars and weight. So that we are not having to eat more to prevent low blood sugars or take more insulin to cope with the diet. A dietitian who is aware of all forms of diet suitable for type 1 and 2 diabetes is best to help here.
There is also information about the
Dawn Phenomenon as it is called where the body's hormone systems prepare us for waking up, sometimes leading to a rise in blood sugars from 4 am onwards. It would take perhaps doing blood sugar tests in the early morning to see if this is happening BUT should be discussed with doctor and nurse first.
