I'm concerned about an uncontrollable diabetes condition.

I have been diagnosed with diabetes and taking medication for about 10 years.

At first, I didn't think it was a big deal, so I just took medication and didn't pay special attention to management. Since I was in a position where interpersonal relationships were essential, I often drank alcohol and had hearty dinners. Still, on weekends, I went hiking and exercised regularly. Now, having left that kind of job, I completely quit drinking and manage my health by eating moderately. I have been walking over 15,000 steps every day without fail for three years, and on weekends, I go hiking and do various exercises diligently. As a result, I lost about 8 kilograms and became relatively slim, but my blood sugar levels didn't decrease; instead, they went up. The glycated hemoglobin, which had dropped to 6.7, recently measured at 8.1. I felt a sense of frustration. Despite exercising diligently and controlling my diet, why are my levels rising? I lost 8 kilograms because obesity is said to be the biggest enemy...

Of course, I inherited my parents' genes, but if I can't manage it even with this, what should I do...

My primary care doctor also couldn't suggest any special methods. Watching people around me suffering from diabetic complications makes me worried. Fortunately, all my complication tests done every six months come back normal, but I still worry. Diabetes medication is not a cure but an insulin supplement, and long-term use can harm the liver and kidneys. I wonder if there are any ways to treat diabetes. I would like to seek help from experts or those with experience.

If this trend continues, the doctor says I will need to start insulin injections, but insulin seems to be the last resort. If anyone has properly treated their diabetes and seen positive results, I would appreciate your advice.
