Nosebleed

Bleeding from the nose; Epistaxis

A nosebleed is loss of blood from the tissue lining the nose. Bleeding most often occurs in 1 nostril only.

Nosebleed

The nose is a very vascular area of the body that contains many arterioles (tiny blood vessels) that can bleed easily. Nosebleeds occur more frequently in the winter when heated indoor air can dry the membranes of the nose. Also, air moving through the nose can also dry out the membranes and can form crusts. These crusts bleed when irritated by rubbing, picking, or blowing the nose. Occasionally, nosebleeds may indicate other disorders such as bleeding disorders, high blood pressure, or hardening of the arteries.

Nosebleed

A nosebleed may be caused by trauma, irritation or dryness of the lining of the nose, allergic rhinitis, colds, or sinusitis. Other causes can include nasal obstruction such as a deviated septum, or foreign objects in the nose. Most nosebleeds begin on the septum, the midline, vertical cartilage that separates the nasal chambers and is lined with fragile blood vessels. This form of nosebleed is not serious and is usually easy to stop. Seek medical help if the bleeding persists after 15 to 20 minutes of treatment, nosebleeds recur, blood persistently drains down the throat, or a neck or serious head injury is suspected.
