What symptom is indicative of esophageal varices in a patient with cirrhosis?

Hematemesis, or vomiting blood, is a key symptom indicative of esophageal varices, particularly in patients with cirrhosis. Esophageal varices are dilated veins in the esophagus that can rupture and lead to significant bleeding, which manifests as hematemesis. This bleeding occurs as a result of increased pressure in the portal circulation due to cirrhosis, leading to the development of these varices. In the context of cirrhosis, the presence of hematemesis is a medical emergency and necessitates immediate evaluation and intervention.

Other symptoms may be present in patients with cirrhosis, such as abdominal distension from ascites, which is fluid accumulation in the abdominal cavity, and black stools, indicating potential gastrointestinal bleeding that has taken place further along the digestive tract. Jaundice is the yellowing of the skin and eyes due to bilirubin accumulation, reflecting liver dysfunction. While these symptoms can be associated with liver disease and its complications, hematemesis is specifically tied to the acute issue of ruptured esophageal varices and is thus the most indicative symptom in this scenario.
