What causes dizziness?

Vertigo only occurs in very few people, but because it has certain genetic causes, people with a family history of vertigo are more likely to develop the disease. Jianying mainly refers to the situation in which a person often suffers from dizziness, and after this happens, it has a great impact on a person's normal daily life. So besides genetic reasons, what other causes may cause vertigo?

Vertigo is characterized by a dizzy feeling during an attack, and even nausea, vomiting, cold sweats and other symptoms of autonomic nervous system disorders.

Causes of vertigo:

1. Anemia If the elderly have dizziness, fatigue, and pale complexion, they should go to the hospital for a check-up to see if they are anemic. If the elderly do not pay attention to nutrition and health care, they are very likely to suffer from anemia. In addition, elderly patients with indigestion, peptic ulcers, gastrointestinal bleeding, and chronic inflammatory diseases can all develop anemia.

2. High blood viscosity. Hyperlipidemia, thrombocytosis, etc. can cause high blood viscosity and slow blood flow, resulting in insufficient blood supply to the brain, easy fatigue, dizziness, weakness and other symptoms. There are many reasons for high blood lipids, the most important of which is the unreasonable diet structure.

3. Patients with arteriosclerosis feel dizzy, often suffer from insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs. Cerebral arteriosclerosis reduces the inner diameter of blood vessels, reduces blood flow in the brain, and causes insufficient blood and oxygen supply to the brain, causing dizziness.

4. Cervical spondylosis often causes tightness in the neck, limited flexibility, occasional pain, numbness, coldness, and heaviness in the fingers. Cervical vertebrae hyperplasia compresses the cervical vertebral artery, causing insufficient blood supply to the brain, which is the main cause of dizziness caused by this disease.

5. Hypertension In addition to dizziness, patients with hypertension often suffer from headaches, palpitations, irritability, tinnitus, insomnia and other discomforts.

6. Heart disease In the early stage of coronary heart disease, some people may feel headache, dizziness, weakness in limbs, difficulty concentrating, etc. This is mainly due to atherosclerosis of the coronary arteries of the heart, resulting in insufficient blood supply and causing dizziness.

7. Meniere's syndrome Meniere's syndrome is an inner ear disease, and vertigo is the main manifestation of Meniere's syndrome.

8. Blood diseases such as leukemia, pernicious anemia, and blood hypercoagulable diseases can all cause dizziness, which can be diagnosed through blood system examinations.
