Part of hypoglycemia can be effectively cured, and part of hypoglycemia will lead to adverse consequences. The prognosis of hypoglycemia is mainly related to the underlying etiology. After the occurrence of hypoglycemia, it can be treated accordingly according to the different clinical symptoms. If it is only mild hypoglycemia, the patient often shows panic, cold sweat and weakness, etc. The symptoms can be relieved quickly by eating sugar water or carbohydrates in time. Severe hypoglycemia can lead to hypoglycemic coma, which generally requires intravenous use of 50% glucose injection, which can also quickly relieve the symptoms of hypoglycemia. To further clarify the cause of the disease and understand the underlying causes of hypoglycemia, such as common overdose of drugs during diabetes treatment, debilitating diseases, severe malnutrition, tumor diseases or endocrine system diseases, etc., resulting in hypoglycemic episodes, active treatment of the underlying causes should be carried out, and attention should be paid to monitoring changes in blood sugar during the process, and timely adjustments should be made when necessary.
