Primary Sclerosing Cholangitis (PSC) is a long-term disease that causes inflammation and eventual scarring of the liver and bile ducts. The term 'primary' indicates that there is no other medical condition or infection which can explain the symptoms. PSC is a chronic condition, meaning that it lasts for many years, but the time it takes for symptoms to develop varies. The causes of PSC are not known, but there is evidence that in some cases it may be due to a defect in the immune system which causes inflammation when the body tries to fight infection.
A hepatologist is a doctor who specializes in the diagnosis and treatment of liver diseases.
Remember that for the proper selection of health professional that treats primary sclerosing cholangitis you must consider the nature, severity and symptoms you are presenting.
