Patients with hypoglycemia can drink glucose water, and also drink honey water, sugary drinks, consume cookies and snacks to elevate blood sugar and relieve the symptoms of hypoglycemia. Also pay attention to rest immediately, should not be active, and keep the surrounding air circulation. Hypoglycemia is defined as blood sugar lower than 2.8mmol/L. When hypoglycemia occurs, the body has two kinds of reactions, one is sympathetic excitement, patients will have panic and sweating, hunger, dizziness, weakness, some patients may also have nausea and vomiting, and serious patients may have psychiatric symptoms, delirium and epilepsy. If the patient is conscious, glucose water, snacks, cookies, etc. should be given immediately. If the blood sugar does not recover in time after ingestion, glucose water can be given again after 10 minutes to try to make the blood sugar rise rapidly. Another kind of damage to the central nervous system, where the patient shows hypoglycemic coma, is very dangerous and should be taken to the hospital immediately for infusion of glucose or glucagon and adrenal corticosteroids. While the patient is unconscious, it is not recommended to feed any food to avoid choking and coughing and choking. When the patient has a hypoglycemic attack, the blood sugar may gradually drop. If the condition allows, it is better to take blood sugar and eat at the same time, which can clearly diagnose whether it is caused by hypoglycemia. If the patient is in an emergency and does not have a blood glucose meter at hand, he or she should also eat food first to raise blood glucose as soon as possible, and then actively seek medical attention after the symptoms are relieved and the cause is diagnosed and treated.
