How much sugar can be taken to relieve hypoglycemia in diabetic patients needs to be decided in conjunction with the patient’s condition. Generally speaking, if the patient with hypoglycemia is conscious, taking 15-20 grams of sugar by mouth (glucose is preferred) can usually relieve it. If the patient’s blood sugar does not recover after the above measures, he or she needs to go to the hospital in time. Hypoglycemia often occurs in diabetic patients in the course of treatment, at which time the patient will have obvious cold sweat and dizziness. If not treated in time, it is likely to jeopardize the patient’s life. It should be noted that when severe hypoglycemia occurs in diabetic patients, when coma occurs, then glucose injection is required under the guidance of the doctor to maintain the patient’s blood sugar. It is recommended that diabetic patients with hypoglycemia go to the hospital in a timely manner, under the guidance of the doctor to carry out targeted treatment, so as not to delay the condition, triggering adverse consequences.
