The causes of nasal bleeding are multiple and can be localized to the nasal cavity or can be triggered by systemic disease.
Systemic factors, such as dysfunctional coagulation mechanisms, the presence of severe liver and kidney disease, or hematologic disorders, can trigger nasal bleeding, but these disorders cause more bleeding and often require combined treatment of the primary disease, which is severe and mostly incurable, and therefore recurrent heavy bleeding can occur.
The majority of bleeding from local factors in the nasal cavity is seen in inflammatory or tumor-like diseases. Tumors, if detected and treated early, can quickly improve nasal bleeding, but there are very few malignant tumors that are so destructive that they are often untreatable, resulting in frequent heavy nasal bleeding.
Most bleeding from nasal inflammation is completely curable, mostly due to rhinitis or sinusitis disease, which leads to vesicular bleeding of the nasal mucosa, often in small amounts, and can be effectively controlled by local pressure or medication to stop the bleeding after cautery and treatment of the inflammation of the nasal cavity.
