Old migraine may be related to sleep factors, dietary factors, neuropsychiatric factors, endocrine factors and so on. 1. Sleep factor: If you have too much stress in your life for a long time and often stay up late, it will easily lead to poor sleep quality and insufficient sleep time, which may cause migraine headache frequently. 2. Dietary factors: If you often eat spicy and stimulating food, drink too much coffee and alcohol in your daily life, it may lead to brain nerve dysfunction and frequent migraine. 3. Neuropsychiatric factors: When the body and mind are stimulated by the external environment or when the mind is overly tense for a long time, depression, anxiety and other emotions may arise and migraine may occur. 4. Endocrine factors: Migraine sufferers are more female than male, and are prone to develop migraine during adolescence. Hormone levels in the body change before and after menstruation, making it easy for migraine symptoms to recur. Frequent migraine patients should go to the hospital in time, after the cause is clear, standardized treatment under the guidance of the doctor.
