What to do if you feel dizzy after having blood drawn

After the blood was drawn, the patient experienced dizziness, nausea and vomiting, among other symptoms. What should I do if I feel dizzy after having my blood drawn? This condition is called dizziness. It is caused by autonomic nervous system dysfunction caused by the patient's mental stress. Additionally, it may be caused by anemia, hypoglycemia. Instructions: When you have your blood taken or your treatments repeated, you can talk to your doctor ahead of time and help you do something ahead of time. Go to the hospital to check your blood to see if it is anemia.

① 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 characteristics are three major symptoms: dizziness, sleep disorders, and memory loss, as well as occipital headache, mild paresis, speech disorders, and irritability. The disease generally develops slowly. The characteristic of this type of dizziness is that it is easy to occur or worsen when the body position changes.
