徐大爷今年64岁,上岁数后,他每天睡得很少。但是近半年来,他发现自己白天觉特别多,到医院就诊,被确诊为糖尿病。原来,徐大爷的嗜睡是糖尿病在作怪。糖尿病患者容易出现嗜睡,主要是因为糖尿病患者糖代谢紊乱,血糖不能被机体(如脑组织)充分利用,导致血糖升高,大量糖分由尿中排出,会引起体力减退、精神萎靡,甚至使中枢神经系统的氧化应激反应减弱,引起嗜睡。老年糖尿病患者往往同时合并高黏血症及脑血管病变(如脑动脉硬化等),致使脑动脉供血不足。大脑对氧气十分敏感,大脑缺血、缺氧即会引起哈欠频频,昏昏欲睡。2型糖尿病患者在 Xu uncle 64 years old this year, after the age, he slept very little. However, in the past six months, he found himself feeling particularly much during the day and went to the hospital for medical examination and was diagnosed with diabetes. It turned out that Xu drowsiness is diabetes at work. Diabetes is prone to lethargy, mainly because of diabetic patients with disorders of glucose metabolism, blood glucose can not be fully utilized by the body (such as brain tissue), leading to elevated blood sugar, a large number of sugar excreted by the urine, can cause physical decline, apathetic, and even the central Nervous system oxidative stress response weakened, causing drowsiness. Elderly patients with diabetes are often combined with hyperviscosity and cerebrovascular disease (such as cerebral arteriosclerosis, etc.), resulting in cerebral artery insufficiency. The brain is very sensitive to oxygen, cerebral ischemia, hypoxia will cause frequent yawning, drowsiness. Type 2 diabetic patients
