Sorry this is long, but I'm concerned.I had my very first consult with surgeon 2 days ago. We are approximately 4 months from surgery. I have been placed on a 3 month pre surgery diet. Of course when we get down to the last 2 weeks I will go the liquid route. My concern today, is this: I am T2 diabetic. I am drinking a Protein shake for Breakfast and then following meal guidelines the rest of the day. I began my day with a fasting blood sugar of 250. Took my insulin and other meds as prescribed. Drank my shake. 2 hours later I checked bs, it was down to 230, no insulin taken at this time. At lunch, 1.5 hours later.....it was 187. Took my sliding scale with lunch. 2.5 hours later checked bs, it was 56!!! I ate some fruit and a yogurt. checked it 2 hours later it was 67. ate dinner. Went to bed 4 hours later. When I got up this morning 175. I drank my shake and took my morning meds, took bs 2 hours later, 285!!! WTH? I am all over the map!! Has anyone else experience this? Should I hang in there, call surgeons office or call my endo?
