Walking is usually known to lower blood sugar. For diabetic patients, lowering blood glucose generally requires a combination of health education, diet control, exercise, condition monitoring, medication and other measures. Patients with abnormal glucose tolerance can control their blood glucose through simple diet control or exercise, and for diabetic patients, they need to take glucose-lowering drugs such as metformin and acarbose at the same time under the guidance of a doctor. Exercise can increase insulin sensitivity, so patients can perform walking exercise, which helps to lower blood sugar, usually recommended to walk after meals. And the development of exercise plan follows the principle of individualization, gradual and long-term persistence. People with multiple abnormal blood glucose values should consult a doctor to clarify the cause of the disease in order to avoid delaying the condition.
