I had a HbA1c test in February, which unfortunately included my eating over Christmas and it had gone from 65 (3 months earlier) to 66. I was asked by the doctor to have another test 4 weeks later and it has gone up to 70. I'm so upset because I've tried really hard to eat properly and exercise. I don't have a problem refusing sugar anyway and I've really cut down on my carbs. I don't eat pasta, potatoes or rice and very little bread. Does anyone have any ideas what I'm doing wrong? Could a sudden reduction of carbs increase blood levels? My eating over the last 4 weeks has been excellent, I just can't believe my HbA1c has gone up by 5. I feel so disillusioned at the moment because I know I'm going to get another lecture off the doctor and I don't know where I'm going wrong. When I was first diagnosed my HbA1c was 120.
