Most patients with essential hypertension have mild or severe headache and dizziness, which generally worsen with the rise of blood pressure, i.e., the headache is more pronounced in the morning or afternoon of the day, and may be accompanied by other symptoms of hypertension. In some patients with primary hypertension, due to the long-term elevation of blood pressure, the structure and function of the cerebral blood vessels have changed. In this case, you should contact the emergency center in time to treat the patient. Some secondary hypertension can also appear headache, for example, patients with primary aldosteronism can also have headache, but also with increased nocturnal urination periodic paralysis or weakness, etc. Hypertension is mostly persistent increased blood pressure, etc., and this headache is relatively persistent. Another example is that patients with an endocrine disease pheochromocytoma can have episodes of headache with palpitations and sweating, especially some patients with pallor, nausea, tremor, anxiety, abdominal discomfort with a sharp rise in blood pressure and severe headache. Some patients with hypertension who have the above symptoms should seek prompt medical attention to identify the cause so that the cause can be treated. The diagnosis of headache in patients with hypertension is complicated and is also related to the patient’s prognosis, so it is important to ask the clinician to combine the patient’s specific situation in order to come up with a correct diagnosis.
