I was diagnosed with fasting venous blood glucose of 10.23, post-meal blood glucose after 2 hours of 15.20, and HbA1c of 7.4 at the end of June this year. Can I try this method?

Doctor's answer:

Diabetes cannot be cured, and there is no specific medication for it. Don't believe advertisements or so-called. Your blood sugar is very high. The solutions are:
First, dietary control—avoid foods high in sugar, foods with a high glycemic index, and greasy foods.
Second, increase physical activity.
Third, quit smoking and drinking, get good rest, and maintain a calm mood.
You can also take Metformin sustained-release tablets, Pioglitazone hydrochloride dispersible tablets, and Acarbose tablets for treatment.
