Before the appearance of hypertensive nosebleed, there may be signs of dizziness, nausea, or even vomiting, and some patients also have unsteadiness, that is, the performance of a steep rise in blood pressure. Some patients may suddenly squat down while standing, and due to the change of body position, there may be rapid rupture of nasal mucosal blood vessels, resulting in nosebleeds. So usually hypertensive nosebleed patients, the cause is mainly hypertension, need to pay attention to blood pressure. If there are symptoms of dizziness, nausea, vomiting, you need to measure the blood pressure in time, if the blood pressure is high, you need to lower the blood pressure. Keeping the blood pressure stable is the only way to prevent the occurrence of nosebleeds from high blood pressure. The treatment is also to deal with blood pressure rather than ligating blood vessels in the nasal cavity.
