Management of Underlying Cause

Liver disease is not a single condition. Fatty liver, viral hepatitis, alcohol, autoimmune disease, genetic conditions, drugs and bile duct disorders can all lead to cirrhosis, but each requires a different treatment. When the cause is controlled, inflammation settles, scarring often stops progressing and sometimes improves, and the risk of complications and cancer falls. Treating complications without treating the cause is like mopping the floor without turning off the tap.

Finding the Cause

A thorough evaluation usually includes:

• Detailed history of alcohol, medicines, herbal products, family illnesses and exposure risks
• Viral markers for hepatitis B and C, and others as needed
• Autoimmune markers such as ANA, ASMA, IgG and AMA
• Iron studies, ceruloplasmin and other metabolic tests
• Blood sugar, cholesterol and metabolic risk assessment
• Imaging such as ultrasound, MRI and MRCP, and FibroScan
• Liver biopsy in selected cases
• Genetic testing where appropriate

Sometimes more than one cause is present, for example fatty liver with hepatitis B or alcohol, and all should be addressed.

Treatment by Cause

Hepatitis B

• Oral antivirals such as tenofovir or entecavir for those who qualify
• Regular monitoring of viral load and liver tests
• Cancer surveillance, and vaccination of family members
• Never stop treatment without medical advice

Hepatitis C

• Direct-acting antiviral tablets for 8 to 12 weeks, curing the great majority of patients
• Testing after treatment to confirm cure, and continued surveillance if cirrhosis is present

Alcohol-related liver disease

• Complete and lasting abstinence
• Nutritional rehabilitation, thiamine and vitamin supplementation
• Counselling, medicines for relapse prevention and support groups
• Corticosteroids in selected patients with severe alcoholic hepatitis

Fatty liver disease (MASLD/MASH)

• Weight loss, healthy diet and regular exercise
• Control of diabetes, cholesterol and blood pressure
• Newer liver-directed medicines for selected patients with steatohepatitis and fibrosis
• Bariatric surgery in selected patients with severe obesity

Autoimmune hepatitis

• Steroids and azathioprine, with long-term monitoring
• Alternative immunosuppressants if not tolerated

Primary biliary cholangitis

• Ursodeoxycholic acid, with second-line drugs in poor responders

Primary sclerosing cholangitis

• Endoscopic treatment of strictures, management of infections and cancer surveillance
• Care of associated inflammatory bowel disease

Wilson disease

• Lifelong chelators or zinc, with family screening

Hemochromatosis

• Regular phlebotomy or chelation, with family screening

Drug-induced liver injury

• Stopping the offending drug, supportive care and N-acetylcysteine in paracetamol poisoning

Other causes

• Vascular liver diseases, such as Budd-Chiari syndrome, may need anticoagulants, radiological procedures or transplant
• Alpha-1 antitrypsin deficiency, celiac disease, thyroid disease and heart failure need their own specific management

When the Cause Cannot Be Fully Treated

In some conditions, such as PSC or advanced disease, there may be no complete cure. In these cases, care focuses on slowing progression, treating complications and planning for transplant when appropriate.

Can Cirrhosis Improve?

Removing the cause can lead to partial regression of scarring, particularly in hepatitis B and C, autoimmune hepatitis and alcohol abstinence, and can improve survival even in advanced disease. However, patients with cirrhosis still need long-term surveillance for varices and liver cancer, since the risk does not disappear completely.

Family Screening and Prevention

• Genetic conditions: Siblings and children of patients with Wilson disease or hemochromatosis should be tested
• Hepatitis B and C: Household contacts should be tested, and hepatitis B vaccination given to those not immune
• Mother-to-child transmission: Pregnant women with hepatitis B need specialist care to protect the baby
• Metabolic risk: Family members with obesity or diabetes should be assessed for fatty liver

Staying on Track

• Understand the name of your diagnosis and the purpose of each medicine
• Take treatment regularly and attend all follow-up visits
• Keep copies of your reports and prescriptions
• Ask questions if anything is unclear
• Do not switch to unproven remedies, which can be harmful and delay effective treatment

Second Opinions

If the cause remains unclear despite testing, or if treatment is not working, a second opinion from a liver specialist or a tertiary centre can help uncover a missed diagnosis, such as autoimmune overlap, drug injury or a rare metabolic disease.
