Nosebleed refers to blood flowing from the nose or nasal passage. There are two types of nosebleeds:
- Anterior nosebleed—Blood comes from the front of the nose. It usually flows from the semi-rigid walls that separate the two nostrils. This is the most common type of nosebleed.
- Posterior nosebleed—Bleeding starts deep within the nose. This is often more severe and difficult to treat than an anterior nosebleed.

Nosebleeds may be caused by:
- Irritating or breaking the lining of the nose
- Injuring the nasal tissue, which occurs more easily when nasal structure is not normal, or when the passages are inflamed due to a cold or allergies
- Very dry nasal tissue
- Picking or bumping the nose
- Forcefully blowing or rubbing the nose
- Having clot from a previous nosebleed becoming disturbed or dislodged
- Placing a foreign object in the nose
- Having a tumor in the nose and/or sinuses
