Causes

Bleeding from the nose can be causes by numerous factors. These include:
› Trauma, Physical injury, accidents, scarring of the tissues inside and surrounding the nose
› Foreign body stuck in the nose
› Blood clotting disorders such as Hemophilia, Von Willebrand’s Disease
› Hyperviscosity syndrome
› Tick borne diseases such as Ehrlichiosis, Rocky Mountain Spotted Fever (RMSF)
› Poisoning and Toxicity caused from accidental ingestion of insecticides, rodenticides, disinfectants, chemicals

› Parasitic Infections such as Babesiosis, Linguatulosis
› Genetic disorders
› Tumors on / inside the nasal cavity, lesions
› Dental conditions such as fractured tooth, root abscess, chronic swelling in the mouth
› Structural deformities of the nose
› Thrombocytopenia, platelet dysfunction
› Vitamin K deficiency
› Cancers such as Adenocarcinoma, Chondrosarcoma, Fibrosarcoma, Osteosarcoma and Squamous Cell Carcinoma
› Lymphoma (cancer of lymphoid tissue and lymphocytes)
