Frequently asked questions about PSC causes

The Liver Hope Foundation is dedicated to providing comprehensive information and support for individuals affected by liver diseases. Our commitment stems from a deep understanding of the challenges faced by patients and their families. We believe that informed patients are empowered patients, and this section addresses common questions about the causes of primary sclerosing cholangitis (PSC).

What is primary sclerosing cholangitis (PSC)?
Primary sclerosing cholangitis (PSC) is a long-term liver disease that causes inflammation and scarring of the bile ducts—the tubes that carry bile from the liver. Over time, the ducts can become narrowed or blocked, which may damage the liver and eventually lead to cirrhosis. PSC affects everyone differently, and regular care with a liver specialist can help monitor the condition and manage complications.

What are the main reasons someone might get PSC?
The exact cause of PSC is still unknown. Researchers believe genetics, immune-system activity, and environmental factors may all play a role. PSC is strongly associated with inflammatory bowel disease (IBD), especially ulcerative colitis, although not everyone with PSC has IBD. Genetics may increase susceptibility, but PSC is not usually inherited in a simple, predictable way. PSC is not caused by alcohol, poor diet, or something a person did wrong. PSC is not contagious and cannot be passed from person to person. A key message for visitors is that having a risk factor does not mean someone will develop PSC, and people with concerns should discuss appropriate evaluation and monitoring with a healthcare provider or liver specialist.

Why is it important to understand the causes of PSC?
Understanding the causes and risk factors of PSC helps people recognize that it is not caused by personal choices and identify when medical evaluation may be appropriate. After reading, we hope people with PSC, IBD, abnormal liver tests, or other concerns will talk with a healthcare provider or liver specialist about proper evaluation, monitoring, and care.

Is PSC caused by lifestyle choices?
No, PSC is not caused by alcohol, poor diet, or something a person did wrong. It is also not contagious. The exact causes are still being researched, but genetic, immune, and environmental factors are thought to play a role.
