Local cause: The prone part of nosebleed is in the anterior and inferior part of nasal septum, where the submucosal vascular network is rich, and the mucosa is dry and prone to rupture and bleeding. Medically, it is called Lee's District, where about 90% of nosebleeds are found. The reasons are as follows: (1) Blowing your nose, sneezing, coughing and picking your nose. (2) Deviation of nasal septum. (3) Rhinitis: acute, chronic, dry and atrophic rhinitis. (4) Nasal polyps and foreign bodies in nasal cavity. (5) Adenoid hypertrophy. (6) Adenoid hypertrophy. 2.( 1) malnutrition: lack of vitamins a, b, c, d, k or calcium (2) granulocytopenia (3) allergic purpura (4) thrombocytopenia (5) hemophilia (6) aplastic anemia (7) leukemia. Three steps to treat nosebleeds-sitting down, tilting your head, and pinching your nose when nosebleeds, many people will lie down in a panic or pinch their nose bones to stop bleeding because red blood looks terrible and difficult to clean up. In fact, these treatment methods are incorrect. The correct way to treat epistaxis is to sit, lean forward and hold the soft parts of the nose and nose for about 5 minutes. Because most of the broken skin is 0.5 cm at the exit of the nose, most people often plug their nostrils with toilet paper or pinch their nose bones with their hands, trying to stop bleeding by squeezing blood vessels. In fact, this method is ineffective. As for lying down, it's an ostrich's way of staying away from eyes. Blood is not only easy to flow back and choke on the throat, but also can cause nausea and aspiration pneumonia if swallowed too much. Therefore, once the nosebleed is properly handled, if there is too much bleeding, you should ask a doctor for help as soon as possible, otherwise it will cause other complications, which will be even worse!
