Nosebleed (epistaxis)

The blood vessels in the nose are located close to the surface and can burst easily.


The blood vessels in the nose are located close to the surface and can burst easily. The mucous membrane of the nose can be irritated and inflamed, or can be accidentally injured. Other causes for a nosebleed include high blood pressure and a tendency to bleed as well as tumours. The first measure is to squeeze the nostrils together while sitting with the head bent forward. Blood shouldn't be swallowed.


  • Bleeding from one or both nostrils
