Nosebleed and spitting blood may be caused with nasopharyngeal fibroangioma, deviated nasal septum, leukemia and other reasons.
1. Nasopharyngeal fibrous hemangioma: it is a benign tumor in the nasopharynx. If the tumor is large, resulting in more bleeding, blood may flow out of the nose and mouth.
2. Nasal septum deviation: one side of nasal septum is raised, which can cause thin nasal mucous membrane on this side, which is easy to bleed, and if the amount of bleeding is large, it can cause the blood to flow back into the mouth, and the phenomenon of nosebleed and spitting blood can occur at the same time.
3. Leukemia: the proliferation of leukemia cells causes a decrease in the number of platelets, which is prone to the phenomenon of nasal bleeding, and may cause nasal blood to flow back into the mouth, leading to the phenomenon of spitting blood.
It is recommended that people with nosebleeds and vomiting blood go to the hospital in time to clarify the cause of the disease and standardize the treatment under the guidance of the doctor.
