1. Inflammation: infection of the upper respiratory tract can cause acute inflammation of the nasal cavity, nasal mucosa congestion, edema, and even cause erosion, resulting in bloody nasal discharge.
2. Trauma: bad habits of picking the nose or recent trauma to the nose can lead to intranasal bleeding, nasal mucosal secretion increases, resulting in bloody nasal discharge.
3. Cancer: For example, nasopharyngeal cancer and other early symptoms of cancer are blood in the nasal mucus, which is caused by the infiltration of cancer cells into local tissues, resulting in intranasal bleeding.
There are other possibilities for bloody nasal discharge, so patients are advised to go to ENT department of hospital for consultation and treatment after clarifying the cause of the disease.
