Primary sclerosing cholangitis
Informed by recognized medical guidance
Overview
Primary sclerosing cholangitis (PSC) is a long-term disease that causes inflammation and scarring in the bile ducts. Bile ducts are small tubes that carry bile (a fluid that helps digest fat) from the liver to the gallbladder and small intestine. Over time, the damage blocks bile flow, which can damage the liver.
Key facts
- PSC is a chronic (long-lasting) liver condition that gets worse over time.
- It often occurs together with inflammatory bowel disease, such as ulcerative colitis.
- There is no known cure, but treatments can help manage symptoms and slow the disease.
No, primary sclerosing cholangitis is a rare condition.
It most often affects people between the ages of 30 and 60. It is more common in men than in women. Many people with PSC also have inflammatory bowel disease.
Symptoms
- High fever with chills
- Severe pain in the upper right belly that does not go away
- Sudden yellowing of the skin or eyes (jaundice) that worsens quickly
- Confusion or unusual drowsiness
- ⚠Worsening jaundice
- ⚠Severe itching that interferes with daily life
- ⚠Unexplained fever
Common symptoms
- Feeling very tired (fatigue)
- Itching of the skin (pruritus)
- Yellowing of the skin and whites of the eyes (jaundice)
- Pain in the upper right part of the belly
- Fever or chills
- Unintended weight loss
Symptoms in children
- Children may have the same symptoms as adults, plus slower growth or delayed puberty.
Symptoms in older adults
- Older adults may have more advanced symptoms at the time of diagnosis, such as severe itching or jaundice.
Causes
Main causes
- The exact cause of primary sclerosing cholangitis is unknown.
- It is thought to be an autoimmune condition, where the body's immune system mistakenly attacks the bile ducts.
Risk factors
- Having inflammatory bowel disease, especially ulcerative colitis
- Being male
- Having a family history of PSC or other autoimmune diseases
When to see a doctor
See a doctor urgently if:
- If you have severe abdominal pain, high fever, or sudden jaundice, seek urgent medical help.
Book a routine appointment if:
- If you have persistent tiredness, itching, or unexplained weight loss, make an appointment with your doctor.
Diagnosis
Diagnosis usually starts with a physical exam and blood tests. If PSC is suspected, your doctor will recommend imaging tests to look at your bile ducts.
Tests that may be done
- Blood tests to check liver function
- MRCP (Magnetic Resonance Cholangiopancreatography) – an MRI scan that shows the bile ducts
- ERCP (Endoscopic Retrograde Cholangiopancreatography) – a scope test that can also treat blockages
- Liver biopsy – taking a small sample of liver tissue for examination
What to expect at your appointment
The diagnosis process may take several weeks. You will likely be referred to a liver specialist (hepatologist). Some tests are outpatient, meaning you go home the same day.
Treatment
There is no cure for primary sclerosing cholangitis, but treatments focus on managing symptoms, preventing complications, and slowing liver damage.
Self-care at home
- Avoid alcohol completely, as it can harm the liver.
- Maintain a healthy weight through balanced diet and exercise.
- Get vaccinated for hepatitis A and hepatitis B.
- Take vitamin supplements if your doctor recommends them for deficiencies.
Medical treatments
Doctors may prescribe medications to help reduce itching, improve bile flow, and manage complications such as infections. Some people may need antibiotics for bile duct infections. In advanced cases, liver transplantation may be considered.
When is surgery considered?
Surgery is not usually part of treatment for PSC itself. However, if the disease leads to liver failure or bile duct cancer, a liver transplant may be an option.
Living with this condition
Living with PSC means regular check-ups with your liver specialist and monitoring for changes. You may need blood tests and scans every 6 to 12 months.
Lifestyle tips
- Eat a healthy, balanced diet low in saturated fat.
- Stay physically active with moderate exercise, such as walking or swimming.
- Do not smoke.
- Avoid alcohol.
Diet and exercise
A diet rich in fruits, vegetables, whole grains, and lean protein is generally recommended. Exercise can help reduce fatigue and improve overall well-being.
Mental health and emotional wellbeing
Living with a chronic condition can cause stress, anxiety, or depression. It’s important to talk to your doctor about how you feel. Counselling or support groups may help.
Prevention
There is no known way to prevent primary sclerosing cholangitis because the cause is not fully understood.
Vaccines
Vaccination against hepatitis A and B is recommended to protect the liver from these infections.
Screening programmes
There is no routine screening for PSC. However, if you have inflammatory bowel disease, your doctor may monitor your liver function with blood tests.
Complications
If left untreated
- Cirrhosis (scarring of the liver that affects its function)
- Liver failure
- Bile duct infections (cholangitis)
- Bile duct cancer (cholangiocarcinoma)
- Portal hypertension (high blood pressure in the vein that carries blood to the liver)
Long-term outlook
Primary sclerosing cholangitis is a serious condition, but many people live for years with a good quality of life. With regular medical care and healthy habits, you can manage symptoms and reduce the risk of complications. Research continues to improve treatments and outcomes.
