Dizziness is a comprehensive condition that is one of the clinical manifestations of many diseases. There are several common causes of dizziness: first, neurological lesions: such as cerebral ischemic lesions, cerebellar lesions, brain lesions, traumatic brain injury, and certain types of epilepsy. In addition, patients with plant nerve dysfunction and certain neurological disorders may also often feel dizzy. Second, ear diseases: such as diseases in the ear that affect the balance and cause dizziness. Third, internal diseases: such as hypertension, hypotension, various cardiovascular diseases, anemia, infection, poisoning, and hypoglycemia. Fourth, colds: sometimes colds may be accompanied by symptoms of dizziness. Fifth is cervical bone degeneration: due to long-term posture or poor sleeping posture, resulting in cervical vertebrae hyperplasia, deformation, degeneration, tightening of the neck muscles, arterial blood supply is blocked so that the brain blood supply is insufficient, is the main original dizziness often neck tightness, limited flexibility, occasional pain, numbness, cold, a sense of heaviness. Sixth, anemia: if there is dizziness accompanied by weakness and pale face, the possibility of anemia should be considered. In a healthy state, the amount of hematopoietic tissue present in the body as well as the quality and quantity of hematopoiesis has decreased in the elderly, and the aging of the red blood cells themselves makes their utilization of iron much less than before. Therefore, elderly people are prone to anemia if they do not pay attention to nutritional care. In addition. Digestive Diao; Liang, peptic ulcer, gastrointestinal bleeding and patients with chronic inflammatory diseases can be secondary to anemia. Seven is high blood viscosity: hyperlipidemia, thrombocytosis, etc. can increase blood viscosity, slow blood flow, resulting in insufficient blood supply to the brain, prone to fatigue, dizziness, weakness and other symptoms. There are many causes of hyperlipidemia, the most important one is the unreasonable structure of diet, patients eat a lot of high-fat and cholesterol food, and do not like to exercise. At present, the incidence of this type of disease has a rising trend. Eight is cerebral arteriosclerosis disease: patients feel dizzy, and often insomnia, tinnitus, emotional instability, forgetfulness, and numbness of the limbs. Cerebral arteriosclerosis makes the internal diameter of cerebral blood vessels smaller, and blood flow in the brain decreases, resulting in insufficient blood and oxygen supply to the brain, causing dizziness. Nine is heart disease, early stage of coronary heart disease, symptoms are still light, some people may not have chest tightness, palpitations, shortness of breath and other significant discomfort, only feel headache, dizziness, weakness of the limbs, mental concentration, tinnitus or forgetfulness, etc.. The main reason for dizziness at this time is atherosclerosis of the coronary arteries of the heart, which makes the lumen thinner and narrower, causing ischemia and lack of oxygen to the heart. And insufficient blood supply to the heart can cause insufficient blood supply and cause dizziness.
