In fact, many people with migraine do not know how they get migraine, so here I will tell you about the causes of migraine. I. Sleep factor This is a relatively common cause of migraine. The headache is triggered by a serious lack of sleep for a long time, and the stressful work can also cause similar symptoms. The consumption of too much coffee will cause the blood vessels to dilate and stimulate the nerves, and when eating too cold ice cream, the headache will also be felt; the ethanol in alcohol will act on the blood vessels after drinking too much alcohol, which will also cause headache. According to statistics, the ranking of foods that can easily trigger headache are: chocolate, alcoholic beverages, raw dairy products, lemon juice, cheese, red wine, etc. Third, endocrine factors Vascular migraine is mostly seen in adolescent women. It gradually decreases or disappears after menopause, and the attacks are frequent during menstruation, stop during pregnancy and recur after delivery, which indicates that endocrine factors are one of the causes of this disease. Four, genetic factors About 60% of patients can ask for a family history, some patients can have epileptic patients in their families, so it is believed that the disease is related to genetics, but there is no consistent form of heredity. V. Neuropsychiatric factors When the body and mind are subjected to adverse stimuli from the external environment, they often produce emotions such as apprehension and anxiety, which can lead to migraine attacks. According to the survey, 84% of patients with melancholy disorder are accompanied by migraine symptoms. At the same time, after experiencing various unpleasant or violent emotional stimuli such as anger, anxiety and excitement in life or work, they will feel general discomfort, accompanied by migraine symptoms. Sixth, disease factors can cause various causes of intracranial and extracranial inflammation and injury; traction, stretching, displacement and expansion of blood vessels due to mass compression; stimulation of meninges; muscle contraction; direct stimulation of sensory nerves innervating the head and face, etc., which can cause headache. Disease factors: lesions of the eyes, ears, nose and sinuses, teeth, and neck can stimulate the nerves and affect the head and face reflexively or diffusely, all of which can cause reflex or involvement migraine. Chronic migraine can increase the risk of stroke and make a person more likely to suffer from hypertension, hypotension, and arrhythmia. In addition, it can also trigger nausea, vomiting, and some people may experience blurred vision, photophobia and other autonomic dysfunction, such as frequent urination, urination disorders, nasal congestion, hearing loss, tinnitus, and impaired consciousness. These symptoms are not relieved for a long time and cause a lot of pain to the patient, and people with delicate minds may develop depressive symptoms. Therefore, if it is a more severe migraine, i.e. the attacks are more frequent, such as one attack in two or three days, or one attack with pain for two or three days in a row, you should seek hospitalization in time to avoid producing more side effects. If the migraine is produced by disease factors, it can be treated by a method that targets the cause of migraine. The method is microvascular decompression, in which the blood vessels compressing the nerves are pushed out under microscopic guidance and separated by medical isolation pads to protect the nerves from further compression, so that the migraine symptoms disappear and health is restored.
