Why do men often have headaches? Authoritative experts tell you

Some men will experience headaches for no apparent reason, and this condition persists for a long time. The reasons are complicated. For example, some men use drugs for a long time, or their bodies lack iron, or there are other reasons.

1. Side effects of medication

Hypertension drugs such as ACE inhibitors and antidepressants such as amitriptyline can lower blood pressure and induce dizziness. Natasha Stewart, an expert from the British Heart Association, said that some heart patients will become 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 factor in causing dizziness.

2. Iron deficiency

Fatigue is the main symptom of anemia. Due to iron deficiency, the number of red blood cells decreases, the amount of oxygen carried by hemoglobin decreases, and the brain does not have enough blood oxygen, which causes dizziness.

3. Migraine

Professor Susan Haydon of the British Migraine Association said that dizziness is often a precursor to a migraine attack, which is caused by the narrowing of blood vessels in the brain and reduced blood flow.

4. Full body scan

MRI scans can also cause vertigo. The body's balance is controlled by the inner ear, and the strong magnetic field produced by an MRI scan can cause an imbalance in the inner ear's balance organs, which can lead to vertigo.

5. Dehydration

The brain is mostly made up of water. Once the human body is dehydrated, the brain function will be abnormal. Professor Lawrence Armstrong of the University of Connecticut in the United States said that when dehydrated, the blood viscosity increases, the body temperature rises, and the heart rate speeds up. Therefore, when dizziness occurs, you might as well try drinking a large glass of water.

6. Blood pressure and hypoxia problems

Many cases of dizziness are caused by a sudden drop in blood pressure, which causes a short period of brain hypoxia, such as when standing up or getting out of bed suddenly.

7. Swimming

Swimming can easily cause water to enter the ears. Once the water enters the ears, it affects the inner ear balance organ. Before the water in the ears completely dries up, dizziness can last for several hours or even days. Experts point out that emotional tension before and during swimming can lead to a decrease in blood oxygen in the brain, which in turn causes dizziness.

8. Allergies

Allergens such as peanuts, cats, dust and pollen may also cause vertigo. Dr. Adrian Morris, an expert at the Surrey Allergy Clinic in the UK, said that allergies can cause mucus to form in the nasal sinuses and middle ears, affecting the inner ear balance organ and causing vertigo.
