Esophageal varices are the veins that are inflamed or enlarged inside the esophagus. Esophagus is the tube that carries food from mouth to the stomach. When veins get enlarged in the lining of the esophagus it is called esophageal varices. This is a condition that is associated with serious liver disease. With appropriate treatment esophageal varices can be treated.
Esophageal varices occur due to the blockage in the normal flow of blood to the liver usually due to the formation of a clot in the liver. Due to the block in the normal blood flow, the blood flows into smaller blood vessels which are not meant to carry large amount of blood and therefore, the vessels rupture and the blood begins to leak out causing serious complications.
