Have you ever had dizziness and headaches? I believe that many people have experienced this phenomenon of “dizziness and headache”, especially women are more serious. But while you are worried about your “dizziness and headache” phenomenon, do you know that you should actually treat it from the root cause to cure it? Well, today, experts will tell you why the phenomenon of “dizziness and headache”. Dizziness, also known as vertigo, is a subjective sensory abnormality. Dizziness is caused by the expansion of blood vessels in the skin, which increases blood flow and reduces blood flow to the brain. So what are the causes of dizziness? About 1/3 of all adults experience dizziness, which has a variety of causes. Recently, David Hurst, a British neurologist, summarized the 8 most common causes of vertigo. 1. Drug side effects The high blood pressure drug ace inhibitors and antidepressants such as amitriptyline can lower blood pressure and induce vertigo. British Heart Association expert Natasha Stewart said that some heart patients taking diuretics can become dehydrated, which also produces vertigo. Sedatives suppress the central nervous system and slow down brain activity, which is also a major factor in vertigo. 2. Iron deficiency Fatigue and weakness are the main symptoms of anemia. Due to the lack of iron in the body, blood red blood cells are reduced, the amount of oxygen carried by hemoglobin is reduced, and the amount of blood oxygen in the brain is insufficient, thus creating a feeling of vertigo. 3. Migraine According to Professor Susan Haydon of the British Migraine Association, vertigo is often a precursor to a migraine attack, which is caused by narrowing of blood vessels in the brain and reduced blood flow. 4. Whole body scans MRI scans can also cause vertigo. The body’s balance is controlled by the inner ear, and the strong magnetic fields generated by MRI scans can cause an imbalance in the inner ear balance organs, which can lead to vertigo. 5. Dehydration The brain is made up mostly of water, and when the body becomes dehydrated, the brain malfunctions. Professor Lawrence Armstrong of the University of Connecticut says that when dehydrated, blood viscosity increases, body temperature rises and heart rate increases. Therefore, when dizziness occurs, you may want to drink a large glass of water to try. 6. Blood pressure and lack of oxygen Many vertigo is due to a sudden drop in blood pressure and a short period of oxygen deprivation in the brain. For example, getting up or getting out of bed suddenly. 7. Swimming Swimming can easily lead to water in the ears, and once the water has affected the inner ear balance organs, vertigo can last for hours or even days before the water in the ears becomes completely dry. Experts point out that before and during swimming, emotional tension can lead to a drop in the amount of blood oxygen in the brain, followed by vertigo. Allergies Allergens such as peanuts, cats, dust and pollen may also cause vertigo. Dr. Adrian Morris, a specialist at the Surrey Allergy Clinic in the UK, says that allergies can cause mucus to be produced in the sinuses and middle ear, affecting the inner ear balance organs and causing vertigo. After seeing the above information, are you not worried about your “headache” problem? Although today we are telling you about the causes of “headaches”, we still need women to take care of themselves and do the best to protect their bodies.
