Sudden nasal bleeding in hypertensive patients can be seen in two cases: one is due to a sudden increase in blood pressure, which causes an increase in the pressure of the blood vessels in the mucous membrane of the nasal cavity, resulting in the rupture of the blood vessels in the mucous membrane of the nasal cavity. If a hypertensive patient has a nosebleed, it is recommended to go to the hospital in time for consultation and treatment. It is necessary to measure blood pressure first, and if the blood pressure increases sharply, it is recommended to apply intravenous antihypertensive drugs to quickly lower the blood pressure to a reasonable range, but it should not be lowered too fast yet, as the blood pressure may fall too fast to cause acute cerebral ischemic events. Therefore, if you have hypertensive nosebleeds, you must go to the hospital for timely consultation and treatment and listen to the doctor’s arrangement. If the nosebleed is due to bleeding from the mucous membrane of the nose, it is recommended to visit the ENT department.
