Varices are large or swollen blood vessels, which can be located around the oesophagus. The most common cause of esophageal varices is scarring of the liver.
Varices may be small or large, and the bigger they are, the more serious they become.
The vessels can rupture, in which case treatment focuses on preventing bleeding by closing the vessels. Doctors may also recommend medication to reduce blood pressure.
