According to the data, there is an average of one migraine sufferer in 10 people in China, and the patient population may be children or teenagers, or adults. There are both mild and severe migraines, and while mild migraines are generally bearable, severe migraines are often worse than death. In addition, migraines have a high potential to cause cerebral infarction, depression and suicide. So how does this disease, which seriously affects one’s physical and mental health, cause and what are the prevention methods? What are the causes of migraine? It is understood that migraine has a lot to do with genetic factors, mental factors, dietary factors, endocrine changes and bad habits. When a person is overworked, sleep deprivation, eating some dairy products, soy products, chocolate or overeating, smoking and drinking will increase the probability of migraine. In addition, women have more frequent attacks during their menstrual period, and can feel significantly less after pregnancy and childbirth, and some light stimulation, noise and electromagnetic radiation can also trigger migraine. How to prevent migraine? Migraine sufferers should eat less cheese, chocolate, drink coffee, red wine, lemon juice and other foods, quit smoking and drinking, stay up late and get enough sleep to reduce the chance of migraine. If a patient has a sudden and severe headache, use a towel wrapped in ice to put on the head, and the symptoms can be relieved after the blood vessels in the cooled head contract. In patients where these methods do not work, it is recommended that surgery be considered. Microvascular decompression for intractable migraines is effective and has been praised by patients and their families.
