There is no such thing as “the fastest and most effective way to lower blood sugar”. There are ways to lower blood sugar such as dietary control, proper exercise, medication, etc. It is recommended to consult a doctor. 1. Dietary control: According to the patient’s weight, age, height, activity level and other factors, we can set the total calorie requirement of the body, and avoid eating high-fat, high-sugar and high-salt foods, such as ham, sausage, fatty meats, deep-fried foods, cakes, milk tea and so on. 2. Appropriate exercise: Consider appropriate aerobic exercise, such as jumping rope, jogging, swimming and so on. 3. Medication: Take glucose-lowering drugs such as acarbose, metformin or insulin injection as prescribed by the doctor. Patients who need to lower blood sugar should actively cooperate with doctors for treatment.
