intermittent dizziness
Introduction
Introduction Frequent intermittent dizziness is usually caused by low blood pressure or high blood pressure. Young people are generally caused by hypotension, and cervical spondylosis can also cause dizziness. Mild symptoms may include: dizziness, headache, loss of appetite, fatigue, pale face, indigestion, motion sickness and so on. Severe symptoms include: erectile vertigo, cold limbs, palpitations, difficulty breathing, ataxia, ambiguous pronunciation, and even fainting, requiring long-term bed rest.
Cause
Cause
Frequent intermittent dizziness is usually caused by low blood pressure or high blood pressure. Young people are generally caused by hypotension, and cervical spondylosis can also cause dizziness.
Hypotension refers to a series of symptoms caused by decreased blood pressure, such as dizziness and syncope.
High blood pressure: headache, dizziness is common. Mostly induced by emotional excitement, excessive fatigue, climate change or the withdrawal of antihypertensive drugs.
When cervical spondylosis involves the sympathetic nerve, symptoms such as dizziness and headache may occur.

Mild symptoms may include: dizziness, headache, loss of appetite, fatigue, pale face, indigestion, motion sickness and so on.
Severe symptoms include: erectile vertigo, cold limbs, palpitations, difficulty breathing, ataxia, ambiguous pronunciation, and even fainting, requiring long-term bed rest.
These symptoms are mainly caused by a drop in blood pressure, resulting in slow blood circulation and distal capillary ischemia, which affects the supply of oxygen and nutrients in tissue cells, and the excretion of carbon dioxide and metabolic waste. In particular, it affects the blood supply to the brain and heart.
Diagnosis
Differential diagnosis
Differential diagnosis of intermittent dizziness:
1, continuous dizziness: general ordinary acute dizziness, up to one to two weeks or so will disappear, if maintained for more than a month is continuous dizziness. It can be caused by many factors such as brain diseases, anemia, and systemic diseases.
2, dizziness after strenuous exercise: dizziness after strenuous exercise is one of the clinical manifestations of anemia, anemia (anaemia) refers to the total amount of red blood cells in the systemic circulation of blood decreased below normal. However, because the measurement technique of total red blood cells in circulating blood is complicated, it is generally referred to clinically that the concentration of hemoglobin in peripheral blood is lower than the normal standard of the same age group, the same sex and the same region. The normal domestic standards are slightly lower than the foreign standards. In coastal and plain areas, the hemoglobin of adult men is less than 12.5g/dl, and the hemoglobin of adult women is less than 11.0g/dl, which can be considered as anemia. Children under the age of 12 are about 15% lower than the normal value of hemoglobin in adult men, and there is no significant difference between boys and girls. Areas with high altitudes are generally higher.
