Immediate consumption of sugary foods by conscious patients during hypoglycemic episodes generally leads to rapid recovery. Hypoglycemia is caused by a decrease in the concentration of glucose in the blood, at this time should be supplemented with sugary foods, such as candies, cookies, chocolates, etc., and the symptoms of hypoglycemia can be recovered after the concentration of glucose in the blood rises. For patients with hypoglycemic coma, which cannot be relieved by eating sugary food, intravenous glucose treatment should be considered. Frequent hypoglycemic episodes in daily life need to be identified and treated according to the cause. If hypoglycemia cannot be relieved by eating sugary foods or the symptoms recur, it is recommended to go to the hospital.
