The repeated occurrence of hypoglycemia is harmful to the human body, so it is very important to rescue the treatment of hypoglycemia. The treatment of hypoglycemia can be different according to its severity. If it is only mild hypoglycemia, with blood sugar below 3.0mmol/L, the patient only has mild panic, hand trembling and feeding sensation, then it can be rescued by using food with high sugar content, and the blood sugar will rise soon, and the blood sugar can be restored to normal by retesting. If it is a patient with moderate hypoglycemia, with blood sugar below 2.0mmol/L, and the symptoms are very obvious at this time, you can take a sweet drink or directly take 50% glucose injection, and retest blood sugar after half an hour. If the blood sugar rises to normal, just observe for a period of time again. If it is severe hypoglycemic blood, the sugar is lower than 1.5mmol/L, and the patient appears mental symptoms or even coma, then it is a rescue solution for hypoglycemia to replenish sugar intravenously in time. When recurrent hypoglycemia occurs, it is very important to identify the cause. The more common causes of recurrent hypoglycemia include early type 2 diabetes, severe liver and kidney insufficiency, functional hypoglycemia, and islet cell tumor. The fundamental solution to recurrent hypoglycemia is to identify the cause and treat the symptoms.
