Why does cirrhosis cause generalized itching?

The main causes of generalized itching due to cirrhosis are as follows: 1. **Hepatocyte injury**: Cirrhosis may be caused by viral infections, excessive alcohol consumption, and other factors leading to hepatocyte damage and decreased liver function. Accumulation of toxins in the body can irritate the skin, causing generalized itching. 2. **Bile stasis**: Cirrhosis directly affects liver and biliary function, potentially leading to bile stasis. Components in bile, such as bile acids, can irritate the skin, causing pruritus, and may be accompanied by symptoms such as jaundice. 3. **Decreased immune function**: In advanced stages of cirrhosis, patients may experience reduced immune function, making the skin more susceptible to infections, allergies, and other factors, which can result in generalized itching.
