临床表现低血糖呈发作性，时间和频率随病因不同而异，症状千变万化。临床表

The clinical manifestations of <br>hypoglycemia are episodic, the time and frequency vary with the cause of the disease, and the symptoms are ever-changing. The clinical manifestations can be summarized into the following two aspects. <br>1. Autonomous (sympathetic) nerve over-excited performance.

The performance of excessive excitement of the autolognation (communication) nerve<br> When hypoglycemia occurs, epinephrine and epinephrine are released due to the communication nerve and adrenal myelin, and so on, the clinical manifestations are sweating, hunger, panic, trembling, paleness and so on.<br>2. Performance of brain dysfunction<br> It is a series of manifestations of dysfunction in the brain when it lacks sufficient glucose supply. The initial manifestations are mental symptoms such as insulation, mental and language retardation, dizziness, drowsiness, restlessness, irritability, and strange behavior, and in severe cases convulsions, coma and even death.

clinical manifestation<br>Hypoglycemia is paroxysmal. The time and frequency of hypoglycemia vary with the etiology. Clinical manifestations can be summarized into the following two aspects.<br>1. The manifestation of autonomic (sympathetic) nerve hyperactivity<br>When hypoglycemia attacks, due to the release of epinephrine and norepinephrine from sympathetic and adrenal medulla, the clinical manifestations are sweating, hunger, palpitation, trembling, pale complexion, etc.<br>2. Manifestation of brain dysfunction<br>It is a series of manifestations of dysfunction when the brain lacks sufficient glucose supply. At the initial stage, the symptoms were mental inattention, slow thinking and language, dizziness, drowsiness, restlessness, irritability, strange behavior and other mental symptoms.
