Headache is a comprehensive condition and is one of the clinical manifestations of many diseases. The following are common causes of headache: 1. It is a neurological lesion: such as cerebral ischemic lesions, cerebellar lesions, traumatic brain injury, certain types of epilepsy, etc. In addition, patients with plant nerve dysfunction and certain neurological disorders also often feel headache.

It is ear disease: such as ear disease affecting the balance and causing headache. 3.It is internal disease: such as hypertension disease, hypotension disease, anemia, infection, poisoning, hypoglycemia, etc. 4.It is cold: sometimes cold may be accompanied by headache symptoms. 5.It is cervical bone degeneration: due to long-term posture or poor sleeping posture, resulting in cervical vertebrae hyperplasia, deformation, degeneration, tightening of neck muscles, obstruction of blood supply to the brain, which is the main cause of headache, often tightening of the neck, limited flexibility, occasional pain, numbness and coldness of the fingers, and a feeling of heaviness. 6. It is anemia: if there is headache accompanied by weakness and pale face, the possibility of anemia should be considered. In a healthy state, the amount of hematopoietic tissue present in the body as well as the quality and quantity of hematopoiesis has declined in the elderly, and the aging of the red blood cells themselves makes their utilization of iron much less than before. Therefore, if the elderly do not pay attention to nutritional health care, they will easily suffer from anemia. In addition… Indigestion, peptic ulcer, gastrointestinal bleeding and chronic inflammatory diseases can be secondary to anemia. 7, is high blood viscosity: hyperlipidemia, thrombocytosis, etc. can increase blood viscosity, slow blood flow, resulting in insufficient blood supply to the brain, prone to fatigue, dizziness, weakness and other symptoms. There are many causes of hyperlipidemia, the most important one is the unreasonable structure of diet, patients eat a lot of high-fat and cholesterol food, and do not like to exercise. At present, the incidence of this type of disease has an increasing trend. 8, is cerebral arteriosclerosis disease: patients feel dizzy, and often insomnia, tinnitus, emotional instability, forgetfulness, numbness of the limbs. Cerebral arteriosclerosis makes the internal diameter of cerebral blood vessels smaller, and blood flow in the brain decreases, resulting in insufficient blood supply and oxygen supply to the brain, causing headaches. 9. It is the early stage of heart disease and coronary heart disease: the symptoms are still light, and someone may not have significant discomfort such as chest tightness, palpitations, shortness of breath, etc., but only feel headache, dizziness, weakness of limbs, difficulty in concentration, tinnitus or forgetfulness, etc. The main reason for dizziness at this time is atherosclerosis of the coronary arteries of the heart, which makes the lumen thinner and narrower, causing ischemia and lack of oxygen to the heart. Insufficient blood supply to the heart can cause insufficient blood supply to the brain and cause headache. 10.The rate of migraine patients caused by insomnia is about 65%.
