I was told two years ago that I had prediabetes (HBA1C 44). This was a big shock to me, as I am very slim (5ft 8ins tall, weigh less than 9st) and very active. The doctor basically said there was nothing I could do about this, just take the prescribed medication when I became fully diabetic. However, I found this website, and also Diet Doctor, and greatly reduced my carb intake. Last year my HBA1C was down to 39, but this year it is back up to 42! I know these levels are not ridiculously high, but I am concerned they have gone up and not down. Total cholesterol is also up to 8.8 - I have a funny feeling the doctor will soon be wanting to talk to me (again!) about statins! I an now at a little bit of a loss as to what to do next. Two years ago I cut out all bread, pasta, rice, potatoes etc, and have been even more careful with this over the past year, so am completely at a loss as to why the numbers are going up. I walk a minimum of three miles each day, usually more in the region of 7-10 miles. What else can I do?!!! Should I cut carbs to an extremely low level? To give some background, I am 63years old, have a heart defect (left atrial isomerism), underactive thyroid, raised blood pressure and glaucoma. Apart from all that I am really healthy (honestly!) and do not need any more health issues in my life! Any advice/encouragement would be very gratefully received, I feel pretty frustrated at the moment.
