Now I know why I often feel dizzy!

Dizziness is a common thing in daily life. Sometimes you may experience dizziness when you suddenly stand up or get up. There are many reasons for dizziness, which may be disease factors, such as colds, fever, anemia, blood pressure disease, etc. Dizziness is not a big deal, but it is not a small matter either. It is necessary to take it seriously, find the cause and prescribe the right medicine. So what are the factors that cause dizziness?

1. Cold

Sometimes a cold may be accompanied by symptoms of dizziness. At this time, you must rest well, avoid catching a cold, take medicine on time and drink plenty of water. The dizziness will go away after you recover.

2. Fever

Febrile illnesses can also cause dizziness. Because fever consumes a lot of energy and evaporates a lot of water, weakness and dehydration after the fever subsides are normal. Dizziness is caused by the dilation of skin blood vessels, increased blood flow and reduced blood flow to the brain.

3. Hypertension

Long-term high blood pressure leads to insufficient blood supply to the brain, which is one of the causes of dizziness. When people with low blood pressure have a drop in blood pressure, the blood flow to the brain will decrease, causing insufficient blood supply to the brain, resulting in cerebral ischemia and hypoxia, which in turn causes dizziness.

4. Cerebral arteriosclerosis

Cerebral arteriosclerosis reduces the inner diameter of blood vessels, reduces blood flow in the brain, causes insufficient blood and oxygen supply to the brain, and causes dizziness.

5. Anemia

Dizziness is a common typical symptom in the early stages of iron deficiency anemia. The cause of dizziness in anemia is iron deficiency in the body, which causes a decrease in hemoglobin, affecting the ability of hemoglobin to carry oxygen. Therefore, anemia patients often experience dizziness.

6. Arrhythmia

Some more serious arrhythmias can cause dizziness, such as paroxysmal supraventricular tachycardia, frequent premature beats, severe atrioventricular block, etc.

7. Pregnancy

Dizziness is a common symptom in pregnant women. In mild cases, the head feels heavy and the feet feel light-headed, and walking is unstable; in severe cases, the eyes become black and the patient suddenly faints. Health knowledge

8. Others

Lack of rest, excessive hunger, sudden standing, excessive computer use, etc. may all lead to insufficient blood supply to the brain and symptoms of dizziness.
