Nosebleeds (epistaxis, nose bleed) can be dramatic and frightening. Fortunately, most nosebleeds are not serious and usually can be managed at home, although sometimes medical intervention may be necessary. Nosebleeds are categorized based on where they originate, and are described as either anterior (originating from the front of the nose) or posterior (originating from the back of the nose).
- Anterior nosebleeds make up more than 90% of all nosebleeds. The bleeding usually originates from a blood vessel on the nasal septum, where a network of vessels converge (Kiesselbach plexus). Anterior nosebleeds are usually easy to control, either by measures that can be performed at home or by a health care practitioner.
- Posterior nosebleeds are much less common than anterior nosebleeds. They tend to occur more often in elderly people. The bleeding usually originates from an artery in the back part of the nose. These nosebleeds are more complicated and usually require admission to the hospital and management by an otolaryngologist (an ear, nose, and throat specialist).
One out of every seven people will develop a nosebleed at some time in their lives. Nosebleeds tend to occur more often during winter months and in dry, cold climates. They can occur at any age, but are most common in children aged 2
to 10 years and adults aged 50 to 80 years. For unknown reasons, nosebleeds most commonly occur in the morning hours.
