A colleague has been prediabetic for 5 years and her BS were up and down. She asked her GP if she could go on to Metformin to stabilise her blood sugar and her GP agreed. She told me that she now eats what she likes and her blood sugars stay normal. I told her that I have managed to reduce my hba1c by diet but its a constant thing and she replied that she couldn't do that as life would be miserable and its better for her body organs to have a consistent BS. Is this something I should ask my GP about? Thanks all
