Esophageal varices occur(s) when there is excess pressure within the portal system and surrounding vessel and may lead to life-threatening bleeding.
Esophageal varices are several veins located in the esophagus that become enlarged or swollen, which can be life-threatening to the person who has them because they can open up causing bleeding.
The esophageal varices are commonly caused for the scarring (cirrhosis) of the livers. This scarring cuts down on blood fluid through the liver, and because of that more blood flows through the veins of the esophagus. That extra blood causes the veins in the esophagus to inflate superficially.
The esophagus is the tube that connects the throat and stomach.
