Exercise is helpful for lowering blood glucose, but the effect of exercise in lowering blood glucose is limited. If the blood glucose level can be maintained in the ideal range through exercise, you can not eat glucose-lowering drugs and monitor blood glucose regularly; if the blood glucose control is not satisfactory after exercise and diet control, you need to take medicine or inject insulin under the guidance of a doctor. Research shows that regular exercise can improve insulin resistance, increase the sensitivity to insulin, and assist in lowering blood glucose. There are many kinds of oral hypoglycemic drugs in common use, such as metformin, acarbose, glimepiride, repaglinide, dagliflozin, etc. Insulin injection can be used to lower the blood glucose as prescribed by the doctor if necessary. It is recommended that patients with high blood glucose actively cooperate with doctors to maintain their blood glucose level within the ideal range, so as to avoid serious consequences.
