What are esophageal varices?

Esophageal varices are specifically recognized as enlarged veins located at the lower end of the esophagus. This condition typically arises in the context of portal hypertension, which is an increased blood pressure in the portal venous system often resulting from liver cirrhosis or other liver diseases. As the pressure within these veins increases, they can become engorged and vulnerable to rupture, leading to significant complications such as life-threatening bleeding.

The understanding of what esophageal varices are highlights the importance of monitoring patients with liver conditions, as these varices can present without symptoms until they become critically dangerous. The identification of esophageal varices is crucial for the effective management of patients at risk, as preventive measures and treatments may be necessary to mitigate the risk of hemorrhage.
