Yes, walking can lower blood sugar. Walking is an excellent form of aerobic exercise, consuming calories, enhancing cardiovascular oxygen capacity, and increasing the body's basal metabolic rate, all of which are beneficial for lowering blood sugar. Exercise therapy is crucial in diabetes management, but walking on an empty stomach should be avoided as it increases the risk of hypoglycemia. It is recommended for patients to walk about half an hour after meals, emphasizing consistency. However, walking alone cannot entirely replace medication for lowering blood sugar. While walking can contribute to lowering blood sugar, the effect is limited, and the magnitude is also restricted. Diabetic patients are advised to combine lifestyle interventions with medication.
