Why do I feel dizzy every night?

Dizziness is a common disease for all of us, and it is also very common to experience dizziness during sleep at night. Dizziness during sleep at night may be caused by a disease in the nervous system, or it may be a symptom caused by long-term stress and excessive fatigue of the body and brain. Brain injury or brain disease can also easily lead to symptoms of dizziness.

Why do I feel dizzy when I sleep every night?

There are many causes of dizziness, on the one hand it is related to mental and psychological factors, on the other hand it is also related to physical factors. For example, long-term lack of sleep, poor physical condition, or other physical illnesses such as hypoglycemia, anemia, etc. For severe cases, it is recommended to seek medical attention in time and receive appropriate treatment.

Causes and common diseases

Common causes of dizziness include:

1. Nervous system diseases

Such as cerebral ischemic lesions, cerebellar lesions, brain lesions, brain trauma, certain types of epilepsy, etc. In addition, patients with autonomic dysfunction and certain neuroses also often feel dizzy.

2. Ear diseases

For example, ear diseases may affect balance and cause dizziness.

3. Internal medicine diseases

Such as hypertension, hypotension, various cardiovascular and cerebrovascular diseases, anemia, infection, poisoning, hypoglycemia, etc.

4. Cold

Sometimes a cold may cause dizziness.

5. Cervical vertebrae degeneration

The main cause of dizziness is the growth, deformation, and degeneration of the cervical vertebrae caused by long-term poor posture or sleeping position, tightening of the neck muscles, and obstruction of arterial blood supply, resulting in insufficient blood supply to the brain. The patient often experiences tightness in the neck, limited flexibility, occasional pain, numbness and coldness of the scalp and fingers, shoulder pain, a feeling of heaviness, and even nausea and palpitations.

6. Anemia

If dizziness is accompanied by fatigue and pale complexion, the possibility of anemia should be considered. Patients with indigestion, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases may all develop anemia.

7. High blood viscosity

Hyperlipidemia, thrombocythemia and other conditions can increase blood viscosity and slow blood flow, resulting in insufficient blood supply to the brain, and easily leading to symptoms such as fatigue, dizziness, and weakness. Currently, the incidence of this type of disease is on the rise.

8. Cerebral arteriosclerosis

The patient feels dizzy and often suffers from insomnia, tinnitus, emotional instability, forgetfulness, and numbness in the limbs. Cerebral arteriosclerosis reduces the inner diameter of cerebral blood vessels, reduces blood flow in the brain, causes insufficient blood and oxygen supply to the brain, and causes dizziness. The clinical features are three major symptoms: dizziness, sleep disorders, and memory loss. There are also manifestations such as occipital headache, mild paresis, speech disorders, and irritability. Generally, the disease progresses slowly. The characteristic of this type of dizziness is that it is easy to occur or worsen when changing body position.
