HbA1c increased over 6 months.

Hi there @sgiossi . I sympathize with you. I was diagnosed prediabetic late 2019, then tipped over into the diabetic range. I brought it back down. I have no wriggle room weight wise, as my weight is at the very low end of normal. My HbA1c was for a time hovering around 6.3% then my last HbA1c was 5.8%, so very pleased with that. I doubt very much it will be 5.8% when I have my Ac1 tested again in a few days. My blood sugars have definitely gone up. And that's doing around 25000 - 30000 steps a day.
This is just my personal view, even though 5.8% is in the non diabetic range, it's too close to being prediabetic and can tip over if you are not on the button with those reduced carb meals, so I agree with your Dr. For those non diabetics who have stable blood sugars, who have never been pre diabetic, 5.8% is just fine. If your blood sugars are labile and likely to rise , then , in my personal opinion, 5.8 is too close to being prediabetic.

Lack of sleep can raise your blood sugars, it's a body stressor , so too can everyday life stresses, more so if it is stress invoking event. Losing weight, for many does often result in lower blood sugars , but not for everyone. I went on a very low carb diet, lost too much weight and it barely budged my blood sugars. Hot weather and an illness can bump up your blood sugars. Blood sugars do fluctuate, but if they are consistently raised then that will impact your HbA1c's.

Maybe reviewing your diet will give you more positive results. Removing some high carb items, like rice, pastas, baked goods that use flours such as wheat or rice flours. Desserts and fruit juices contains sugars that will bump up your blood sugars. Dropping back some of your carbs may just work. Diet is your easiest option. If you are already watching your carb intake, maybe revisit what you do eat and see where you can cut back. Try periodic fasting. Some members get good results from that.

Exercise, particularly resistance training can also help to drop your blood sugars. This does require commitment, but the benefits are broader, so not just for diabetes but for your heart and lungs, and for maintaining muscle strength, which help support your joints. Building muscle, not necessarily bulking , but muscle mass, means your muscles utilize more blood sugar. Muscles use nearly 70% of your daily energy needs, which means blood sugars.
