The most common cause of nosebleeds that do not stop is bleeding due to rupture of small arteries, which is caused by dryness and erosion of the mucous membrane of the nasal cavity. Because of the high pressure of the artery, the bleeding is more urgent and not easy to stop. If you do not have good results in stopping the bleeding at home, you need to go to the hospital for examination. After the bleeding point is found by a professional doctor, the situation can be improved by welding the small blood vessel break using minimally invasive methods such as laser or microwave. Drugs that lubricate the mucous membrane, such as peppermint paraffin oil, can be used for the nasal cavity. Usually, saline or seawater can be used for nasal rinsing, avoid strenuous exercise, do not eat spicy and stimulating food, and do not smoke or drink alcohol.
