When hypoglycemia occurs, patients will feel hungry and also show symptoms such as panic, cold sweat and hand trembling. Some patients may also experience dizziness and weakness, and have mental symptoms such as delirium and epilepsy, and in severe cases, they may even be in a hypoglycemic coma. During a hypoglycemic attack, patients who feel hungry and panicky can eat small cookies, snacks, desserts, cakes and other foods, or drink sugar water. Generally, the discomfort can be gradually relieved 5-10 minutes after eating these foods. If the symptoms continue not to be relieved or worsen and a hypoglycemic coma occurs, the patient needs to be sent to the hospital for intravenous glucose infusion as soon as possible to get the patient out of hypoglycemia, while paying attention to keeping the patient’s respiratory tract open to avoid choking and coughing, which may lead to the patient’s accidental aspiration. After the correction of hypoglycemia, we should look for the causes of hypoglycemia. Most of the hypoglycemia occurs mainly due to the low amount of food, or due to the overdose of hypoglycemic drugs and excessive insulin in diabetic patients, especially in elderly patients who suffer from other diseases and do not want to eat after taking hypoglycemic drugs, hypoglycemia can easily occur. It is also seen in some obese patients and patients with obese diabetes mellitus, who may have hypoglycemia before meals due to hyperinsulinemia. If it is identified that the patient is hypoglycemic due to hyperinsulinemia, or if the diabetic patient has hypoglycemia, it is recommended that the patient should eat regularly and at the same time carry some snacks in his pocket and write a note for passersby to help him eat and take him to the doctor in time.
