What are the different types of nosebleeds? There are two types of nosebleeds: one is blood in the snot and the other is continuous bleeding. A small amount of blood in the nasal discharge or blood in the sputum when coughing may be a sign of malignant tumor in the nose. In addition to blood in the nose, malignant tumor may also have other symptoms such as nasal congestion and pus; nasopharyngeal cancer may also cause hearing loss, neck mass, diplopia and other symptoms; in the advanced stage of tumor, facial numbness, headache and other symptoms may appear. However, sometimes acute and chronic sinusitis can also cause blood in the snot, so do not be alarmed when you see blood in the snot, but go to the hospital for examination in time. Another kind of rhinorrhea is bleeding, usually caused by nasal mucous membrane erosion or dryness, but also caused by nasal trauma, for the elderly, hypertension, arteriosclerosis is a common cause. In addition, some systemic diseases may also manifest as bleeding, such as leukemia, thrombocytopenia, severe liver function impairment and other abnormal coagulation function. How to deal with nosebleeds when they occur? It is important to stay calm when nosebleeds occur. If it is a small amount of nasal bleeding, you can compress the bleeding side of the nose, or use gauze rolls and cotton to compress the nasal cavity to stop the bleeding, and also do cold compresses on the forehead.
