Hypoglycemic coma

Hypoglycemia is called when the blood glucose is lower than 3 mmol / L, and severe hypoglycemia can cause coma. Common reasons are: too much insulin or oral, hypoglycemic medicine and too little food; exercise increased, but did not increase the food intake accordingly. Hypoglycemic coma: the cause may be spontaneous, that is, due to too little or no food, especially when infection occurs; or insulin-induced (for islet tolerance test or use of insulin to treat anorexia); Or hypoglycemia due to endogenous insulin secretion caused by a high-sugar diet or a large amount of glucose injection. Due to insufficient cortisol, liver glycogen storage is reduced, growth hormone is reduced, insulin sensitivity is increased, thyroid function is reduced, and intestinal absorption of glucose is reduced. Therefore, fasting blood glucose is usually lower in normal times. The above situation is easy to cause hypoglycemic coma. This type of coma is most common. When hypoglycemia occurs, the patient is weak, dizzy, dizzy, sweating, flustered, pale, and may have headache, vomiting, and nausea. Blood pressure is generally low and cannot be measured in severe cases. Can be irritable or unresponsive, pupils reflect light, disappear after the initial hypertenopathy, the scratch test can be positive, may have increased muscle tone or convulsions, convulsions, and fall into a coma in severe cases.
