Hypoglycemia is a condition in which plasma glucose is lower than normal. According to experts, hypoglycemia means that the fasting blood glucose concentration in adults is less than 2.8mmol/L. Diabetic patients can be diagnosed with hypoglycemia when their blood sugar level is lower than 3.9 mmol/L.

Hypoglycemia can lead to over-excitation of the sympathetic nerves, such as sweating, hunger, palpitation, trembling, paleness, etc., as well as brain dysfunction. The initial manifestations are lack of concentration, slow thinking and language. , dizziness, drowsiness, restlessness, irritability, strange behavior and other mental symptoms. In severe cases, convulsions and coma may occur. If timely rescue is not received, it may even directly lead to death. Therefore, hypoglycemia is more harmful than hyperglycemia.

There are many types of hypoglycemia, which can be roughly divided into three categories.

The first category is fasting hypoglycemia. This type of hypoglycemia can be divided into three categories. They are endocrine hypoglycemia, hepatic hypoglycemia, and nephrogenic hypoglycemia.

Fasting hypoglycemia is mainly caused by excessive consumption or insufficient intake. This type of hypoglycemia can be caused by long-term hunger, strenuous exercise, malabsorption, etc. This requires diabetic patients to reasonably control their diet and develop good eating habits.

The second type is reactive hypoglycemia. This type of hypoglycemia is often caused by appropriate stimulation. It can also be divided into three categories. They are idiopathic postprandial (functional) hypoglycemia, nutritional hypoglycemia, hypoglycemia associated with type 2 diabetes or impaired glucose tolerance.

The third category is hypoglycemia caused by drugs. According to the current medical level, at least 20 kinds of drugs are currently known to cause hypoglycemia.

It can be seen that hypoglycemia is very harmful, and diabetic patients need to be careful.
