Hello there, I can understand your concern about your mother s health. The very fact that she underwent a pancreatic surgery is the reason she has diabetes and has to be treated with Insulin injections. Pancreas also produces another hormone called Glucagon which prevents low sugars in normal people. Because your mother now has no functional pancreas according to your doctor she wont produce glucagon also. So her risk for getting low sugars is high. Each time she get low sugars her sugars may suddenly rise to compensate. It would have helped me to know the doses of insulin that your mother is taking. I would suggest monitor her sugars every day and give insulin based on her sugar values. Adjust insulin gradually based on the sugar levels. That way you will know her sugar levels before giving insulin and she wont suffer from dangerous low sugars. Do discuss this option with your diabetologist who can accordingly suggest doses. This is called sliding scale of insulin and once a steady sugar levels are reached then that dose can be fixed without further daily monitoring. Her targets for sugar control can be kept a little lenient. Fasting around 120-140 mg and after meals around 180-200 mg would be ok for her. Hope this helps. Take care.
