Hi, Welcome to HCM, Diabetes Type 1 patients need to be under constant supervision of Doctors. You as a care taker for him, you should also be aware and educated about his health issues. The most common cause for twitching and convulsions in Diabetic patients is Hypoglycemia. There are more chances of Hypoglycemia during midnight, and early hours. Hypoglycemia is more dangerous then hyperglycemia. I would say you immediately take him to Diabetes Specialist / Diabetes Nurse/ Physician or family Physician. If in case you do not have immediate access to the doctor, you do following 1. Monitor regularly his blood glucose level, six times an a day-before each meal ( breakfast, Lunch and Dinner) and two hour after meals. keep a recording. 2. Doses and type of Insulin Injection has to be determined according to the levels of Glucose. You may write us the dose, timings site and type of Injection Insulin he is taking, so we can advise you accordingly. 3. Best thing is that we should avoid hypoglycemia, but if it happens you should immediately give him Some biscuits, Lump of sugar, Juice Etc. followed by some food with low Glycaemic index. There may be some other reasons for Convulsions, which we have to look for, if the problem persist even after tight control of blood sugar. I have tried to give you some important relevant advise, though there are many more things to know and understand about Diabetes. Your boy friend and you need thorough counselling and education about it. Dr Hamdani 3.
