Elevated blood glucose levels after exercise are usually normal, and normal people are generally able to continue exercising within a reasonable range. Elevated blood glucose after exercise may be due to excessive exercise resulting in the body’s energy consumption, liver glycogen into glucose to meet the body’s metabolic needs. Or it stimulates the body to produce a large number of adrenal hormones, thus the blood sugar rise. This is a transient increase in blood glucose, which usually returns to normal after rest. Exercise can help strengthen the body, speed up the metabolism and promote blood circulation. However, patients are advised to avoid excessive strenuous exercise, which may cause excessive energy consumption and lead to hypoglycemia. If the blood glucose value is still not normalized after sufficient rest, it is recommended that the patient go to the hospital in time and follow the doctor’s instructions to avoid delaying the condition.
