Esophageal varices result can from portal hypertension, regardless of the age group. The increased resistance to blood flow through the portal system is due to prehepatic, intrahepatic, and suprahepatic obstruction, but the most common causes of portal hypertension in children include portal vein thrombosis (prehepatic) and biliary atresia (intrahepatic).

The most common causes of upper GI bleeding in children older than 12 years are duodenal ulcers, esophagitis, gastritis, and Mallory-Weiss tears.
