Type 2 diabetes is usually treated with diet control, exercise therapy and drug intervention. In diet control, low-salt, low-fat and low-sugar diet is the mainstay, with regular rationing, and try to eat foods with high dietary fiber, such as green vegetables, cucumbers and oats, etc. If you eat foods with high starch content, such as potatoes, Chinese yams, corn, taro and sweet potatoes, you should try to reduce the intake of staple foods. As for exercise therapy, exercise time is usually appropriate 30-60 minutes after meals, with outdoor aerobic exercise as the mainstay, suggesting brisk walking, jogging, tai chi, table tennis, swimming, etc., with no less than 450 minutes of exercise per week, and sufficient sunlight time should be guaranteed. Drug intervention should be carried out under the guidance of a specialist, do not randomly listen to non-professionals to buy health care products, test blood sugar on time and follow up regularly.
