Dizziness can be caused by a variety of diseases, and the most common ones are as follows. 1. Headaches caused by head lesions are divided into headaches caused by intracranial diseases and headaches caused by extracranial diseases. Dizziness, which many people think is a minor problem, can be dizzy when hungry, dizzy around menstruation, and dizzy when standing up after squatting for a long time. In general, occasional dizziness or dizziness due to a change in position is not a big problem and should not be a major concern. However, if you are dizzy for a long time, you should pay attention to it, because long-term dizziness or frequent dizziness may be a precursor to serious illness. Dizziness is a comprehensive condition that is a clinical manifestation of many diseases. The following causes of dizziness are common: (1) 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. (2) Ear diseases (2) Diseases of the ear (2) Diseases of the ear that affect balance and cause dizziness. (3) Internal diseases such as hypertension, hypotension, various cardiovascular diseases, anemia, infection, poisoning, hypoglycemia, etc. (4) Cold Sometimes a cold may be accompanied by symptoms of dizziness. (5) Cervical bone degeneration Due to long-term posture or poor sleeping posture, resulting in cervical vertebrae hyperplasia, deformation, degeneration, tightening of neck muscles, obstruction of blood supply to the arteries, resulting in insufficient blood supply to the brain, is the main cause of dizziness often tightening of the neck, limited flexibility, occasional pain,: F finger numbness, coldness, and a feeling of heaviness. (6) Anemia If dizziness is accompanied by weakness and pallor, 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. Patients with dyspepsia, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases can all suffer from secondary anemia. (7) High blood viscosity Hyperlipidemia and thrombocythemia can increase blood viscosity and slow blood flow, resulting in insufficient blood supply to the brain, which can lead to fatigue, dizziness and weakness. 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 is on the rise. (8) Cerebral arteriosclerosis Patients feel dizzy, and often suffer from 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. (9) Heart disease, coronary heart disease In the early stage, the symptoms are still mild, and some people may not have significant discomfort such as chest tightness, palpitations, shortness of breath, but only feel headache, dizziness, weakness of limbs, mental concentration, tinnitus or forgetfulness. 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. (10) Insomnia Clinical statistics show that the rate of insomnia-induced migraine patients is about 65%, for this type of patient group, in medicine, the use of pure Chinese medicine preparations of Western medicine glutathione for the combination of Chinese and Western medicine treatment can achieve more significant and ideal results. The best solution for dizziness is prevention. For example, quit smoking and drinking, avoid raw, cold, greasy and too salty, too spicy and too acidic food; eat more fresh vegetables, fruits, bean sprouts, melons, black fungus, celery, water chestnuts, beans, milk, fish, shrimp, etc.; appropriate physical activity, maintain a happy and calm state of mind, etc. 2.Symptoms of brain injury: having had a head injury in the past few days. Headache lasts more than one day, or there is a few seconds of unconsciousness after the injury, a burst of headache, memory loss, vomiting. 3, anemia elderly people who have dizziness, weakness and pale face should go to the hospital to check if they are anemic. Elderly people are prone to anemia if they do not pay attention to nutritional care. In addition, anemia can be secondary to dyspepsia, peptic ulcer, gastrointestinal bleeding, and chronic inflammatory diseases in elderly patients. Anemic elderly people such as dizziness, weakness, pale face 4, hypertension Hypertensive patients are often accompanied by head swelling, panic, irritability, tinnitus, insomnia and other discomforts, in addition to dizziness. 5, heart disease early coronary heart disease, some people may feel headache, dizziness, weakness of the limbs, mental concentration is not easy, etc.. This is mainly due to atherosclerosis of the coronary arteries of the heart, resulting in insufficient blood supply and causing dizziness. 6, high blood viscosity high blood lipids, thrombocytosis, etc. can cause high blood viscosity, slow blood flow, resulting in sufficient blood supply to the brain, resulting in easy fatigue, dizziness, weakness and other symptoms. There are many causes of hyperlipidemia, the most important one is the usual diet structure and unreasonable. 7, cerebral atherosclerosis patients feel dizzy, and often insomnia, tinnitus, emotional instability, forgetfulness, and numbness of the limbs. Cerebral arteriosclerosis makes the inner diameter of blood vessels smaller, and the blood flow in the brain decreases, resulting in insufficient blood and oxygen supply to the brain, causing dizziness. 8. Cervical spondylosis often presents with neck tightness, limited flexibility, occasional pain, numbness and coldness of the fingers, and a feeling of heaviness. Cervical spine hyperplasia squeezes the vertebral artery in the neck, causing insufficient blood supply to the brain, which is the main cause of dizziness caused by this disease.
