Liver Cirrhosis: Complications and Risks

• Liver cirrhosis is a condition characterized by liver damage from various causes followed by self-repair that leads to the formation of fibrous tissue, which becomes hardened and replaces normal liver tissue. This leads to a decrease in the liver function and impair liver nutrient production, hormone regulation, drug processing, and detoxification capabilities.
• Basic self-care measures to reduce the risk of liver cirrhosis include avoiding alcohol consumption and undergoing testing for hepatitis A and B viruses. Patients without immunity to these viruses should consider vaccination.
• FibroScan helps assess liver fibrosis and cirrhosis, monitor treatment response, and guide patient care. It is a non-invasive alternative to liver biopsy for many patients.

Liver cirrhosis occurs when the liver is repeatedly damaged over time. As the liver tries to repair itself, scar tissue forms and gradually replaces healthy liver tissue. This reduces blood flow through the liver and impairs its ability to produce essential proteins, regulate hormones, process medications, and remove toxins from the body.

• Liver cirrhosis can result from a variety of conditions that cause long-term liver damage, including:
• Long-term alcohol use
• Chronic hepatitis B or hepatitis C infection
• Fatty liver disease (including metabolic dysfunction-associated steatotic liver disease)
• Long-term exposure to liver-damaging toxins or certain medications
• Less common conditions, such as Wilson disease, cystic fibrosis, bile duct disorders, and autoimmune hepatitis

Yes. Alcohol is only one of many causes of liver cirrhosis. You can help reduce your risk by maintaining a healthy weight, eating a balanced diet, limiting unnecessary medications and herbal supplements, avoiding exposure to liver toxins, getting vaccinated against hepatitis B, seeking treatment for viral hepatitis when appropriate, and having regular health check-ups if you are at increased risk.

As liver cirrhosis progresses, it can lead to serious complications, including:

1. Esophageal varices
   Scarring of the liver increases pressure in the portal vein, causing enlarged veins (varices) in the esophagus. If these veins rupture, they can cause severe bleeding, leading to vomiting blood, shock, and, in some cases, can be life-threatening.
2. Ascites
   Ascites is the buildup of fluid in the abdomen caused by increased pressure in the liver’s blood vessels and reduced production of albumin, a protein that helps keep fluid in the bloodstream. Symptoms include abdominal swelling, leg swelling, and a protruding abdomen. Treatment may include a low-sodium diet, diuretics, or drainage of the fluid (paracentesis). People with ascites are also at risk of abdominal infections, which require prompt treatment with antibiotics.
3. Hepatorenal syndrome (HRS)
   Hepatorenal syndrome is a type of kidney failure that can occur in advanced liver disease. Although the kidneys are structurally normal, severe liver dysfunction reduces blood flow to the kidneys, causing them to stop working properly. Early diagnosis and treatment are essential.
4. Hepatic encephalopathy
   When the liver can no longer remove toxins effectively, substances such as ammonia build up in the bloodstream and affect the brain. Symptoms range from poor concentration, confusion, sleepiness, and hand tremors to severe drowsiness or coma. Common triggers include infections, constipation, dehydration, and bloody stool.

Although liver cirrhosis cannot always be reversed, early treatment can slow its progression, reduce complications, and improve quality of life.

1. Treat the underlying cause
   Managing the condition causing liver damage is the most important step. This may include treating hepatitis B or C, completely avoiding alcohol, managing fatty liver disease, or addressing other underlying liver disorders.
2. Maintain good nutrition
   Good nutrition is essential because people with cirrhosis are at increased risk of malnutrition and muscle loss. Most patients require 35–40 kcal/kg/day and 1.2–1.5 g of protein/kg/day. Eating 4–6 small meals a day, including a late-evening snack, helps maintain energy levels and preserve muscle mass. Patients with fluid retention or ascites should also limit salt (sodium) intake to help reduce swelling and fluid buildup.
3. Screen for esophageal varices
   Upper endoscopy may be recommended to check for enlarged veins (esophageal varices). If varices are found, medications or endoscopic treatment can help reduce the risk of bleeding.
4. Screen for liver cancer
   People with liver cirrhosis have a higher risk of developing liver cancer, regardless of the underlying cause. Liver ultrasound every 6 months is recommended for ongoing surveillance.
5. Stay up to date with vaccinations
   Patients should be tested for immunity to hepatitis A and B and vaccinated if needed. Keeping routine vaccinations up to date, such as influenza and pneumococcal vaccines when appropriate, can also help reduce the risk of infection.
