Primary Sclerosing Cholangitis: Who's at Risk and Why?
Published: May 09, 2024
Primary sclerosing cholangitis (PSC) is a rare but serious liver disease. While anyone can develop PSC, certain factors can increase your risk.
Contents
Inflammatory Bowel Disease
The strongest risk factor for PSC is having inflammatory bowel disease (IBD), particularly ulcerative colitis. About 70-80% of PSC patients also have IBD. The connection isn't fully understood, but it's thought that gut inflammation may trigger immune responses that affect the liver. Interestingly, PSC can develop before, during, or after IBD diagnosis.
Genetic Factors
While PSC isn't directly inherited, genetic factors play a role. Certain variations in genes related to immune function can increase susceptibility. Having a first-degree relative with PSC raises your risk. However, most people with these genetic factors don't develop PSC, suggesting environmental triggers are also important.

Demographics
PSC is more common in certain groups. It's diagnosed most often in people aged 30-40. Men are affected more frequently than women, with a ratio of about 2:1. PSC is more prevalent in Northern European populations, suggesting possible genetic or environmental influences specific to these regions.
Frequently Asked Questions
There's no known way to prevent PSC, even in high-risk groups.
No, most IBD patients don't develop PSC.
PSC can occur in children, but it's less common than in adults.
No specific lifestyle changes are proven to reduce PSC risk.
Key Takeaways
Understanding PSC risk factors can help with early detection and management, but remember that having risk factors doesn't mean you'll definitely develop the disease.
If you have risk factors for PSC, discuss with Doctronic whether any preventive measures or monitoring might be appropriate for you.Related Articles
