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. The 8 most common causes of vertigo. 1. Drug side effects The hypertension 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 will be dehydrated, which also produces vertigo. Sedatives inhibit the central nervous system and slow down brain activity, which is also a major factor in causing vertigo. 2. Iron deficiency Fatigue and weakness are the main symptoms of anemia. Due to the lack of iron in the body, the red blood cells decrease, the oxygen-carrying capacity of hemoglobin decreases, and the amount of blood oxygen in the brain is insufficient, thus creating a sense of vertigo. 3.Migraine Professor Susan Haydon of the British Migraine Association said that vertigo is often a precursor to migraine attacks, which is caused by narrowing of blood vessels in the brain and reduced blood flow. 4. Whole body scans MRI scans may also cause vertigo. The balance of the body is controlled by the inner ear, and the strong magnetic field generated by MRI scans can cause an imbalance in the balance organs of the inner ear, which in turn can lead to vertigo. 5. Dehydration The brain is mostly composed of water, and once the body is dehydrated, brain function will be out of order. Professor Lawrence Armstrong of the University of Connecticut says that blood viscosity increases when dehydrated, 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 up violently, etc. 7.Swimming Swimming can easily lead to water in the ears. Once the water in the ears affects 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. 8. Allergies Allergens such as peanuts, cats, dust and pollen may also cause vertigo. Allergies can cause mucus to be produced in the sinuses and middle ear, which affects the inner ear balance organs and causes vertigo. After seeing the above information, are you not worried about your “headache” problem? Although we are telling you about the causes of “headache” today, we still need women to take more care of themselves and do the best to protect their bodies.
