Hypertensive headaches are very common in the population of hypertensive patients. About 55.4% of hypertensive patients have headaches, and some statistics are even higher, accounting for about 80%. In general, headaches are more common in young adults with hypertension, relatively less common in older adults, and may be more common in women than in men, with more severe headaches in the initial or acute phase of hypertension and less severe headaches in the stable phase of hypertension. However, it should be noted that the level of blood pressure is not directly proportional to the degree of headache, but is more closely related to the fluctuation of blood pressure. The nature of headache produced by hypertensive headache: 1.Dull pain, throbbing throbbing pain: It can be seen in the front or back of the head on one or both sides of the head, or the whole head. 2.Tightness-like pain around the head or persistent dull pain: mostly located in the neck and neckline under the occiput, sometimes there may be mild neck stiffness. 3.Diffuse swelling pain or dull pain in the whole head. Typical hypertensive headache patients often wake up with frontal-occipital headache in the early morning, and the headache can be aggravated after lowering the head or holding the breath and exerting force, which can be accompanied by dizziness, tinnitus, insomnia, forgetfulness and mood swings. If the patient’s hypertension progresses rapidly and the blood pressure value is above 200/130 mmHg, it is called malignant hypertension or acute hypertension, and there may be retinal exudation, hemorrhage and optic papillary edema, and the disease develops rapidly, and the incidence of its headache is 84.5%-87%. If the blood pressure cannot be effectively controlled, together with certain triggering factors, such as strong emotional changes, mental trauma, mental and physical overwork, stimulation of cold and endocrine disorders, the patient will have severe headache, dizziness, vertigo, may have nausea, vomiting, chest tightness, palpitation, shortness of breath, blurred vision, abdominal pain, frequent urination, scanty urination, difficulty in urination, sweating and shaking of hands and feet, etc. This condition is called hypertensive crisis. If a patient with acute hypertension or severe bradykinetic hypertension is accompanied by obvious cerebral arteriosclerosis, the blood pressure is often above 200/120mmHg or even up to 250/150mmHg, which can lead to persistent and obvious spasm of small cerebral arteries, followed by passive or compulsory dilation, resulting in acute cerebral circulatory disorders, excessive perfusion of brain tissue, resulting in cerebral edema and increased intracranial pressure, and Severe headache, dizziness, nausea, vomiting, frequent restlessness, slow and strong pulse rate, respiratory distress or slowing down, visual impairment, black haze, convulsions, blurred consciousness and even coma, transient hemiplegia, aphasia, hemianesthesia, etc. This condition is called hypertensive encephalopathy and needs to be diagnosed and treated correctly in time.
