A 50 yr old male presented with history of hematemesis – 500 ml of blood and on examination shows BP – 90/60, PR – 110/min and splenomegaly 5 below lower costal margin. Most probable diagnosis is
**Core Concept**
The patient presents with signs of hypovolemic shock (low blood pressure, tachycardia) and upper gastrointestinal bleeding (hematemesis) along with splenomegaly. The likely diagnosis involves a condition causing both upper GI bleeding and splenomegaly.
**Why the Correct Answer is Right**
The presence of splenomegaly and upper GI bleeding in a patient with hypovolemic shock suggests a diagnosis of **portal hypertension**. This condition is often caused by **cirrhosis of the liver**, which leads to increased pressure in the portal vein. The increased pressure causes **varices** (enlarged veins) to form in the esophagus and stomach, which can bleed easily. The cirrhosis also causes splenomegaly due to portal hypertension leading to congestion in the spleen.

**Clinical Pearl / High-Yield Fact**
Remember that cirrhosis can lead to portal hypertension, which in turn causes varices and splenomegaly. The presence of both upper GI bleeding and splenomegaly in a patient with hypovolemic shock should raise the suspicion of cirrhosis.
**Correct Answer: D. Cirrhosis of the liver**
