Type 2 diabetes requires lowering blood sugar, regulating life and eating habits, a low-sugar, low-fat diet, more physical activity, and treatment with oral hypoglycemic medications. First, the first choice of medication metformin extended-release tablets is as the first choice of clinical guidelines. Second, it can lower the blood sugar after three meals, such as the use of acarbose tablets, 1-2 tablets once, three times a day, taken orally at meals. Third, the use of long-acting sulfonylurea drugs, such as gliclazide, glimepiride, gliquidone and other drug therapy. Fourth, new glucose-lowering drugs, such as DPP-4 enzyme inhibitors and GLP-1 agonists, can be used to effectively lower blood sugar.
