In brief, I was diagnosed last week with a reading of 15. gp is treating it as type 2 cos of my age, mid 40, but thinks I will need insulin soon as it is probably an autoimmune cause not diet or familial. (i had colitis and thyroid probs as well.) Started me on metformin 500 3x a day. Went back 6 days later as losing weight (already under 10 stone) cos awful nausea and cramps. Bm that day 3 hrs post a v small breakfast was 17 so he reduced metformin to 1gm Sr and added in gliclazide 80mg twice a day. Told by diabetic nurse to only test once a day and waiting for more strips on prescription so limited anyway. My bm yesterday pre lunch was 12 which is better than the 17 it was the day before at the surgery but I did check it 2 hrs after evening meal and it was 17 again. Does it take a while for the tabs to start having a positive effect. Am worried that gp seems v keen to get me on insulin and don't know how long is realistic to give the tabs time to work. My diet was already low sugar and low fat and with being v slim already, I cant make many more diet changes that may help. Waiting to go on a 3 hr course with a diabetic specialist nurse but by then, worried the gp will have upped tabs, decided they don't work and got me on insulin. Is there a diabetic med algorithm which indicates how long something should be tried for. All v confusing and worrying.
