Planking is just a personal habit and usually has no therapeutic effect on blood sugar and cannot lower it. To lower blood sugar, patients with high blood sugar need to be guided by their doctors through diet, exercise and medication. The details are as follows: 1. Diet: patients with diabetes need to reduce sugar intake, such as potatoes, lychees and other fruits and vegetables with high sugar and starch content, and try to replace them with coarse grains, green leafy vegetables and other foods with low glycemic index, such as quinoa and spinach. 2. Exercise: Moderately increase the amount of aerobic exercise, such as swimming, jogging, brisk walking, etc., can improve the body’s consumption of excess sugar and the body’s sensitivity to insulin. 3. Medication: patients should take hypoglycemic drugs as prescribed by the doctor, and patients with type 1 diabetes and type 2 diabetes that are not well controlled by medication can be treated with insulin injection. Patients with high blood glucose should go to the hospital in time to clarify whether the blood glucose is pathologically elevated. Once diagnosed, the medication should be prescribed by the doctor.
