feel dizzy

Dizziness, also known as dizziness, is a subjective sensory abnormality. It can be divided into two categories: one is rotational vertigo, which is mostly caused by vestibular nervous system and cerebellum dysfunction, mainly caused by dumping feeling, feeling shaking or scene rotation. Second, general dizziness, mostly caused by some systemic diseases, is mainly dizziness and feels top-heavy. Classification and common diseases dizziness is a common symptom, not an independent disease. Therefore, we can classify and describe the diseases that cause dizziness, so that everyone can have a deeper understanding of "dizziness". 1. Rotational vertigo can be divided into peripheral vertigo and central vertigo according to the etiology. (1) Peripheral vertigo: refers to vertigo caused by inner ear labyrinth or vestibular neuropathy. Common in Meniere's disease, labyrinthitis, drug-induced vertigo (caused by streptomycin or gentamicin) and vestibular neuritis. (2) Central vertigo: refers to vertigo caused by diseases of brain stem, cerebellum, brain and spinal cord. It is common in vertebrobasilar insufficiency, intracranial tumor, intracranial infection, multiple sclerosis, vertigo epilepsy and traumatic vertigo. 2. General vertigo (1) Cardiogenic vertigo: it is common in arrhythmia and cardiac insufficiency. (2) Pulmonary vertigo: It can be seen in pulmonary insufficiency caused by various reasons. (3) Ophthalmic vertigo: common in ametropia, fundus arteriosclerosis, hemorrhage and ophthalmoplegia. (4) Blood pressure vertigo: Both hypertension and hypotension can cause dizziness. (5) Others: anemia, cervical spondylosis, acute fever, gastroenteritis, endocrine disorders and neurosis can all cause dizziness. Anemic elderly people have symptoms such as dizziness, fatigue and pallor, so they should go to the hospital for examination to see if they are anemic. If the elderly do not pay attention to nutrition and health care, they are prone to anemia. In addition, elderly patients with dyspepsia, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases can all suffer from anemia. 2. High blood viscosity, hyperlipidemia and thrombocytosis. It can increase blood viscosity and slow blood flow, resulting in insufficient blood supply to the brain, causing fatigue, dizziness, fatigue and other symptoms. Among them, there are many reasons for hyperlipidemia, and the most important one is the unreasonable diet structure. 3. Patients with cerebral arteriosclerosis feel dizzy and often have symptoms such as insomnia, tinnitus, emotional instability, forgetfulness and numbness of limbs. Cerebral arteriosclerosis makes the inner diameter of blood vessels smaller, and the cerebral blood flow decreases, which leads to insufficient blood supply and oxygen supply to the brain, thus causing dizziness. 4. Cervical spondylosis often has neck tightness, limited flexibility, occasional pain, numbness of fingers, chills and heaviness. Hyperplasia of cervical vertebra squeezes the cervical artery, resulting in insufficient blood supply to the brain, which is the main cause of dizziness caused by the disease. 5. In addition to dizziness, patients with hypertension are often accompanied by discomfort such as head swelling, palpitation, irritability, tinnitus and insomnia. 6. Heart disease In the early stage of coronary heart disease, some people will feel headache, dizziness, weakness of limbs and difficulty in concentration. Mainly due to cardiac coronary atherosclerosis, resulting in insufficient blood supply and dizziness. 1. The best solution to dizziness is prevention. The elderly should regularly measure blood pressure, heart sound, heart rhythm, blood routine, blood lipid, blood viscosity, EEG, rheoencephalogram and neck X-ray. Take precautions before they happen.
