After fasting aerobics, hypoglycemia requires timely supplementation with sugary foods. The body does not eat in the fasting state, and aerobic exercise at this time will consume a large amount of energy, resulting in a decrease in the concentration of glucose in the blood, causing the onset of hypoglycemia, palpitations, pallor, fatigue, cold sweat and other symptoms. Patients with mild to moderate hypoglycemia need to immediately replenish sugary foods, including sugar water, candy, chocolate, cookies, sugary drinks, etc. For severe hypoglycemia or hypoglycemic coma, intravenous glucose supplementation is needed for treatment. It should be noted that, in daily life, you should avoid exercising on an empty stomach again, which leads to the occurrence of hypoglycemia. Carry some candies with you in your normal life to prevent the occurrence of hypoglycemia. If the symptoms still cannot be relieved after supplementing sugary food, it is recommended to go to the hospital.
