How is winter giddy to return a responsibility?
summary
Dizziness is also known as vertigo, early treatment, let your body recover as soon as possible, normal life. It is a kind of motor or positional illusion, which results in the distortion of the spatial relationship between people and the surrounding environment in the cerebral cortex, resulting in the sensation of rotation, dumping and ups and downs. Now let's talk about how winter dizziness is going on?.
How is winter giddy to return a responsibility?
First: cerebral arteriosclerosis cerebral arteriosclerosis is a kind of arteriosclerosis, because it is easy to cause stroke and has a great risk, dizziness, headache is the early symptoms of cerebral arteriosclerosis. Experts explained that the reason why cerebral vascular sclerosis causes dizziness is that the oxygen and nutrients carried in the arterial blood can not be exchanged to the brain cells through the hardened blood vessels, leading to dizziness due to chronic hypoxia in the brain for a long time. The headache caused by cerebral arteriosclerosis is mostly in the forehead and the back of the brain, and the nature is blunt pain. It is most likely to appear or aggravate the original symptoms when the body position changes.
Second: cervical spondylosis in the elderly, cervical spondylosis is also a common disease. Cervical spondylosis can also lead to dizziness, called "cervical vertigo.". Cervical vertigo accounted for 50% of the dizziness of people over 50 years old. Tan Sheng explained that cervical spondylosis causes dizziness through two mechanisms. Cervical vertebral artery is the "lifeline" of cerebral blood supply. Cervical spondylosis may lead to compression and narrowing of cervical vertebral artery, resulting in cerebral blood supply insufficiency and hypoxia.
Third: heart problems. In general, coronary heart disease has typical symptoms, such as chest tightness, suffocation, angina pectoris, etc., but some people will feel dizzy, mainly because coronary heart disease is the supply of blood to the heart, coronary artery atherosclerosis, stenosis, resulting in reduced blood supply to the heart. If the heart is short of blood supply for a long time and the heart function is decreased, the power to transport blood to the whole body is insufficient. The brain is the highest part of our body, and the brain needs a lot of fresh blood at any time, so it is most sensitive to ischemia and hypoxia. When the heart is ischemic, it causes a decrease in blood supply to the brain, which can lead to dizziness.
matters needing attention
Remind, the winter weather is dry, home heating or sleep like open mouth breathing of the elderly, more likely to cause the loss of body water and lead to blood viscosity. Drinking more water at night is conducive to the dilution of viscous blood and can reduce the risk of cardiovascular and cerebrovascular accidents.
