Hypoglycemia can be said to be a relatively common disease, once suffering from hypoglycemia we will feel more uncomfortable, what are the causes of hypoglycemia at this time? 1, drug factors 1, insulin: insulin injection overdose or injection after too little food intake and relatively excessive activity, may produce the typical acute hypoglycemic reaction. 2. Sulfonylureas: The degree of hypoglycemia caused by these drugs is related to the half-life and metabolic rate of the drugs. When patients have diet reduction, liver and kidney lesions, and adrenal cortex insufficiency, there is the possibility of hypoglycemia. 3. Oral hypoglycemic drugs, especially euglycemia, may also cause hypoglycemia. Disease factors 1. In severe liver disease, the liver cannot effectively regulate blood sugar, and hypoglycemia is likely to occur when the sugar intake is insufficient. 2. Endocrine diseases such as adrenal gland, thyroid gland and pituitary gland may cause hypoglycemia. Functional A kind of functional hypoglycemia with less clear causes mostly occurs in some middle-aged women who are fat. The characteristic of this kind of hypoglycemia is that it often occurs about three or four hours after meals, and the more meals are eaten, the more likely it is to occur. It is currently believed that the cause is that the food the patient eats into her belly stimulates the peptide hormone in the intestine, and this hormone stimulates the secretion of insulin in large quantities, thus lowering the blood sugar to a low level and causing hypoglycemia.
