The reason for frequent dizziness is that some of these tell you the answer.
Dizziness is what most people have experienced, some dizziness is a small problem, but some dizziness indicates a big problem.
Chen Xiaohua introduced that there are many reasons for dizziness, such as lack of iron, lack of oxygen, and low blood pressure.
What is specific?
Iron deficiency fatigue is the main symptom of anemia.
Due to the lack of iron in the body, the red blood cells are reduced, the oxygen carrying capacity of hemoglobin is reduced, and the blood oxygen in the brain is insufficient, resulting in a sense of dizziness.
Migraine Professor of the British Migraine Association Susan Hayden said that dizziness is often a precursor to migraine attacks, which is caused by narrowing of blood vessels in the brain and a decrease in blood flow.
The dehydrated brain is mostly composed of water, and once the body is dehydrated, the brain function will be abnormal.
Professor Lawrence Armstrong of the US Air Force University said that blood viscosity increases during dehydration, body temperature rises, and heart rate increases.
Therefore, when dizziness occurs, try a large glass of water.
Allergens such as allergies to peanuts, cats, dust and pollen can also cause dizziness.
Dr. Adrian Morris, an expert in the Surrey allergy clinic in the United Kingdom, said that allergies can cause mucus in the sinus and middle ear, affecting the inner ear balance organs and causing dizziness.
Drug antihypertensive drugs ace inhibitors and anti-depressants such as amitriptyline will lower blood pressure and cause dizziness.
British Heart Association expert Natasha?
Stewart said that some cardiovascular patients will be dehydrated when taking diuretics, which can also cause dizziness.
Sedatives inhibit the central nervous system and slow down brain activity, which is also a major cause of dizziness.
Swimming and swimming can easily cause the ear to enter the water. Once the water influx affects the inner ear balance organ, the vertigo may be hours or even days before the water in the ear is completely dried.
Experts pointed out that during swimming and during swimming, emotional stress can lead to decreased blood oxygen in the brain, followed by dizziness.
Blood pressure and hypoxia Many vertigo are caused by a sudden drop in blood pressure and a short-term hypoxia in the brain.
For example, suddenly get up or get up.
