The middle and late symptoms are diabetic complications, generally cardiovascular and cerebrovascular diseases and kidney involvement, fundus hemorrhage, deafness and gangrene (diabetic foot). It is most important to diagnose the cause of diabetes before treatment. Type 2 diabetes can be cured according to the cause, but there is no radical cure for type/kloc-0 diabetes at present, because the cause lies in the gene, and we can't dig out the cause from the gene. Type II has many reasons. Most of them are related to nutrient deficiency, such as protein, phospholipid, calcium, zinc, selenium, vitamin B deficiency or mental stress, which can all become independent pathogenic factors of diabetes. If the cause is known and the corresponding nutrients are supplemented, it can be cured with the cooperation of early hypoglycemic drugs. Too much iron, pheochromocytoma, aldosterone system and too much fat in the body can also cause diabetes, which can be improved or eliminated by adjusting the intake of nutrients, or by removing a few tumors to make blood sugar normal. I hope I helped you.
