Great Steveron that you are working with your endocrinologist! Following my distal pancrectomy, my blood sugars have gone from lows of 40 which I never knew was even possible to sustain to highs close to 500. It’s all over the place in other words. Are you wearing a glucose sensor like Freestyle Libre 3 that has an app you can use from your phone? This is critical! In my case, my oncologist and primary defer to my endocrinologist who works out how much insulin I should be getting based on my bimonthly chemo treatments. Diabetics are very sensitive to steroids and to the sugars your chemo drugs may be administered with, but you don’t want to change that. With the right endocrinologist you can find the right amounts of insulin to take during the chemotherapy treatments. I go back to my normal insulin injections less than a week following my chemo session. It’s all about the learning curve!
