Good day, i'm type 1 diabetes since 2010, recently struggling with abnormal blood glucose, i nees to inject sometimes up to 3 timea more, to keep my bg under control, could it be that i'm developing insulin resistance?

Many factors: As you know there are various factors that affect your glucose level. During this quarantine we are seeing many patients requiring additional insulin because there is limited opportunity to exercise, and the added calories being consumed while housebound. Try to stick to a routine including periodic walks, 2-3 times a day and watch your calorie consumption. If the condition persists, call your DR.
