Nosebleed, well-known as epistaxis, is the common form of bleeding from the nose. It is usually seen when the blood drains out through the nostrils. Nosebleeds are most often initiated by local trauma but can also be caused by bacteria, nasal or sinus infections, and sustained inhalation of dry air. Nosebleeds can be dramatic and terrifying. Fortunately, most epistaxis is not severe and can be managed at household, although sometimes medical treatment may be essential. Sometimes in more severe cases, the blood can arise up the nasolacrimal duct and out from the eye. Clotted and fresh blood can also flow down into the stomach and cause nausea and vomiting.
