Cirrhosis is a serious condition where the liver becomes scarred due to long-term, continuous liver damage. This scarring replaces healthy liver tissue, disrupting the liver’s ability to function properly. Although cirrhosis damage is irreversible, treatment can help slow its progression, prevent further liver damage, and manage symptoms.
If cirrhosis progresses significantly, it can lead to liver failure—a life-threatening condition. In the UK, around 4,000 people die from cirrhosis annually, and 700 people need liver transplants to survive.
Symptoms of Cirrhosis
In the early stages, cirrhosis often has no noticeable symptoms. However, as the disease advances and liver function deteriorates, you may experience:
- Early Symptoms:
- Loss of appetite
- Nausea
- Itchy skin
- Later Symptoms:
- Jaundice (yellowing of the skin and eyes)
- Vomiting blood
- Dark, tarry stools (indicating internal bleeding)
- Fluid buildup in the legs (oedema) and abdomen (ascites)
If you notice any of these symptoms, it is crucial to see a healthcare provider promptly.
When to See Your GP
Since early-stage cirrhosis often goes unnoticed and is usually detected during tests for other conditions, you should consult your GP if you experience any of the following symptoms:
- Fever and shivering
- Shortness of breath
- Vomiting blood
- Very dark or black, tarry stools
- Periods of confusion or drowsiness
Causes of Cirrhosis
In the UK, the main causes of cirrhosis are:
- Excessive Alcohol Consumption: Long-term alcohol misuse is a leading cause.
- Chronic Hepatitis C Infection: Long-term infection with the hepatitis C virus can lead to liver damage.
- Non-Alcoholic Steatohepatitis (NASH): A condition caused by the buildup of excess fat in the liver, often associated with obesity and sedentary lifestyles. NASH is on the rise in the UK and is expected to surpass alcohol and hepatitis C as the most common cause of cirrhosis.
Other less common causes include hepatitis B infection and inherited liver diseases like haemochromatosis.
Treating Cirrhosis
While there is no cure for cirrhosis, managing underlying causes, symptoms, and complications can slow its progression and improve quality of life:
- Addressing Underlying Causes: For example, using antiviral medications to treat hepatitis C can prevent further liver damage.
- Lifestyle Changes: Reducing or eliminating alcohol intake and losing weight (if overweight) can make a significant difference.
- Advanced Treatment Options: In severe cases where the liver stops functioning, a liver transplant may be necessary.
Preventing Cirrhosis
- Limit Alcohol Consumption: Not exceeding recommended alcohol limits can reduce the risk of alcohol-related cirrhosis.
- Preventing Hepatitis B and C: These infections can be transmitted through unprotected sex and needle-sharing. Safe practices, including using condoms and not sharing needles, can lower your risk. A vaccine for hepatitis B is available, but there is no vaccine for hepatitis C.
Cirrhosis is a complex condition that requires ongoing care and monitoring. Lifestyle modifications and addressing the underlying causes of liver damage are essential to slow the disease’s progression and improve overall health outcomes. If you have any concerns, reach out to a healthcare provider for a proper diagnosis and treatment plan.
Symptoms of cirrhosis
Cirrhosis is a chronic condition where the liver becomes scarred and damaged due to prolonged liver disease or injury, leading to a decline in its ability to function. Symptoms often emerge as the liver becomes increasingly impaired, progressing over time from subtle signs to severe health issues.
Early-Stage Symptoms of Cirrhosis:
In the early stages, the liver often continues to perform its essential tasks despite being damaged. As cirrhosis progresses and liver function declines, symptoms become more evident. Common early-stage symptoms include:
- Fatigue and Weakness: Persistent tiredness and decreased strength are frequent complaints.
- Loss of Appetite: Many people experience a significant reduction in their desire to eat.
- Weight Loss and Muscle Wasting: Unintended weight loss and muscle atrophy are common.
- Nausea and Vomiting: Feeling sick, sometimes leading to vomiting.
- Tenderness or Pain Near the Liver: Pain or discomfort is often felt in the upper right abdomen where the liver is located.
- Spider-Like Blood Vessels on the Skin: Tiny red lines, or “spider angiomas,” may appear above the waist level.
- Itchy Skin: Severe itching is common due to the accumulation of bile salts under the skin.
- Jaundice: Yellowing of the skin and the whites of the eyes is a result of bilirubin buildup.
- Easy Bruising and Bleeding: Nosebleeds, bleeding gums, and easy bruising are due to impaired blood clotting.
- Hair Loss: Thinning or loss of hair may occur.
- Fever and Shivering: Occasional fever and chills may be experienced.
- Fluid Retention and Swelling (Oedema): Swelling in the legs, ankles, and feet due to fluid accumulation.
- Abdominal Swelling (Ascites): Severe fluid accumulation in the abdomen can create a bloated, distended appearance.
Neurological Symptoms:
As liver function deteriorates, toxins can accumulate in the bloodstream and travel to the brain, leading to a condition called hepatic encephalopathy. Symptoms include:
- Personality Changes and Confusion: Mood swings, irritability, or other personality changes may occur.
- Sleep Disturbances (Insomnia): Trouble falling or staying asleep.
- Memory Loss and Difficulty Concentrating: Problems with focus, forgetfulness, and difficulty with complex tasks.
- Mental Confusion and Drowsiness: In severe cases, this can lead to stupor or coma.
Late-Stage Symptoms:
Cirrhosis in its advanced stages can lead to serious complications due to increased pressure in the veins of the digestive tract (portal hypertension) and impaired liver function. Symptoms may include:
- Vomiting Blood: Blood vessels in the stomach or esophagus may burst, causing internal bleeding visible in vomit.
- Dark or Tarry Stools: Black, sticky stools due to digested blood passing through the gastrointestinal system.
- Severe Fluid Retention (Ascites): The abdomen may swell significantly, appearing “pregnant” due to fluid buildup.
- Multiple Organ Failure: Accumulation of toxins can result in widespread organ dysfunction and failure, ultimately leading to death if untreated.
When to Seek Medical Attention:
It’s important to consult your GP if you notice persistent symptoms of cirrhosis. Prompt medical intervention is critical, particularly if you experience:
- Fever and Chills: A sign of infection or worsening disease.
- Difficulty Breathing: Shortness of breath may indicate fluid accumulation or other complications.
- Vomiting Blood or Black Stools: These symptoms suggest bleeding in the digestive tract and require immediate medical attention.
- Mental Confusion or Extreme Drowsiness: A sign of hepatic encephalopathy, indicating toxins affecting the brain.
Cirrhosis is a serious condition that demands close monitoring and timely intervention to manage symptoms and prevent further liver damage or life-threatening complications.
Causes of cirrhosis
Cirrhosis is a condition characterized by scarring of the liver tissue, resulting from prolonged damage. The progression of cirrhosis can cause significant liver dysfunction, leading to serious complications. Various causes can contribute to the development of cirrhosis, including chronic alcohol consumption, viral infections, metabolic conditions, and autoimmune disorders.
Common Causes of Cirrhosis
1. Alcohol Consumption
- Excessive Alcohol Use: Chronic and heavy consumption of alcohol is a major cause of cirrhosis. The liver metabolizes alcohol, but excessive intake over time leads to liver inflammation and scarring. Individuals who consume more than 14 units of alcohol per week (for both men and women) are at a higher risk.
- Stages of Alcoholic Liver Disease:
- Fatty Liver Disease: This initial stage occurs in nearly all individuals who consume alcohol excessively. It involves fat accumulation in the liver cells, which can resolve with reduced alcohol consumption.
- Alcoholic Hepatitis: This stage involves inflammation of the liver and can occur in up to 30% of heavy drinkers. Severe alcoholic hepatitis may lead to liver failure and death.
- Cirrhosis: The final stage of alcohol-related liver damage, affecting approximately 10% of heavy drinkers. Continued alcohol consumption significantly worsens liver function, leading to life-threatening complications.
2. Viral Hepatitis
- Hepatitis C: Chronic hepatitis C infection is a leading cause of cirrhosis in the UK. The virus is primarily transmitted through blood-to-blood contact, such as through sharing needles.
- Hepatitis B and D: These infections can also cause liver inflammation, which, if untreated, may result in cirrhosis over time.
3. Non-Alcoholic Steatohepatitis (NASH)
- Description: NASH involves fat accumulation in the liver, inflammation, and scarring, similar to alcoholic liver disease but without alcohol as a factor.
- Risk Factors: Obesity, diabetes, high cholesterol, and high blood pressure increase the risk of NASH. It is becoming more prevalent in the UK due to increasing obesity rates and reduced physical activity.
- Progression: Many individuals with NASH may not exhibit symptoms until cirrhosis develops and liver function is compromised.
Other Causes of Cirrhosis
1. Autoimmune Liver Diseases
- Autoimmune Hepatitis: The immune system mistakenly attacks liver cells, causing inflammation and damage over time.
- Primary Biliary Cirrhosis: The immune system targets bile ducts, leading to inflammation and scarring.
- Primary Sclerosing Cholangitis (PSC): A condition in which inflammation leads to scarring and narrowing of bile ducts.
2. Genetic Conditions
- Haemochromatosis: An inherited disorder that leads to excessive iron accumulation in the liver and other organs.
- Wilson’s Disease: A rare condition characterized by copper accumulation in the liver and other parts of the body.
3. Bile Duct Disorders
- Obstructions: Conditions such as bile duct cancer or pancreatic cancer can block the bile ducts, leading to liver damage.
- Budd-Chiari Syndrome: This condition is caused by blood clots that block the veins carrying blood away from the liver, leading to liver damage.
4. Medications and Toxins
- Certain drugs, such as amiodarone (used to treat heart arrhythmias) and methotrexate (used to treat rheumatoid arthritis and some cancers), may contribute to cirrhosis if taken over a long period.
Prevention Tips
- Limit Alcohol Intake: Drink within recommended limits (no more than 14 units per week).
- Protect Against Viral Hepatitis: Practice safe sex, avoid sharing needles, and consider vaccination for hepatitis B.
- Maintain a Healthy Weight: Prevent obesity through regular physical activity and a balanced diet to reduce the risk of NASH.
- Regular Screening and Monitoring: If you have a family history of genetic liver diseases, consult with your healthcare provider for appropriate screenings.
By addressing and managing these risk factors, individuals can help prevent the onset or progression of cirrhosis and maintain better liver health.
Diagnosing cirrhosis
Diagnosing cirrhosis involves a series of tests and evaluations to determine the extent of liver damage and assess its underlying cause. If your doctor suspects you may have cirrhosis, they will begin with a detailed review of your medical history, discuss your symptoms, and perform a physical examination to identify signs of chronic liver disease. Here is a breakdown of the diagnostic process:
Medical History and Physical Examination
Your GP will ask about:
- Your alcohol consumption
- Any past liver infections
- Use of medications
- Family history of liver disease
They will also check for physical signs of cirrhosis, such as:
- Yellowing of the skin and eyes (jaundice)
- Swelling of the abdomen due to fluid accumulation (ascites)
- Enlarged liver or spleen
- Spider-like blood vessels on the skin
Diagnostic Tests
1. Blood Tests
Blood tests can provide a comprehensive view of liver function and detect markers of liver damage. Common blood tests include:
- Liver Function Tests (LFTs): Measure enzymes such as alanine transaminase (ALT) and aspartate transaminase (AST). Elevated levels may indicate liver inflammation.
- Complete Blood Count (CBC): Assesses for anemia or low platelet counts, which may suggest advanced liver disease.
- Clotting Tests: Measures how quickly your blood clots, which can be slower with liver dysfunction.
- Bilirubin Levels: High levels of bilirubin can cause jaundice and indicate liver problems.
- Albumin and Protein Levels: Low levels may indicate decreased liver function.
- Viral Hepatitis Tests: Check for hepatitis B and C, which can cause cirrhosis.
- Autoimmune Markers: May be tested if autoimmune liver disease is suspected.
2. Imaging Tests
Imaging tests help visualize the liver and detect structural changes, fibrosis (scarring), or nodules.
- Ultrasound Scan: Often the first imaging test done. It uses sound waves to create pictures of your liver and can detect signs of cirrhosis, such as an enlarged liver or spleen.
- Transient Elastography (Fibroscan): A specialized type of ultrasound that measures liver stiffness and estimates the amount of scarring present.
- CT Scan (Computerized Tomography): Provides detailed cross-sectional images of the liver and surrounding organs.
- MRI Scan (Magnetic Resonance Imaging): Offers detailed images of the liver and can detect fibrosis, nodules, and other changes indicative of cirrhosis.
3. Liver Biopsy
- Procedure: A small needle is used to remove a sample of liver tissue for analysis under a microscope.
- Purpose: Confirms the diagnosis of cirrhosis and helps identify the cause.
- Risks: Generally performed under local anesthesia, it may require a hospital stay.
4. Endoscopy
- An endoscope (thin, flexible tube with a camera) is inserted through your mouth to examine the esophagus, stomach, and upper part of the small intestine.
- Purpose: Detects esophageal varices (swollen veins), which are common in cirrhosis due to increased pressure in the portal vein.
Grading the Severity of Cirrhosis
To assess the severity of cirrhosis and guide treatment decisions, different grading systems are used:
1. Child-Pugh Score
This system grades cirrhosis based on five factors (bilirubin, albumin, INR or clotting ability, ascites, and encephalopathy) and classifies the severity from:
- Class A: Mild
- Class B: Moderate
- Class C: Severe
2. Model for End-Stage Liver Disease (MELD) Score
- This system uses blood tests to predict the severity and urgency of a liver transplant.
- Higher MELD scores indicate a more severe disease and a greater need for transplantation.
When to See a Doctor
Seek immediate medical attention if you experience:
- Persistent fever, chills, or shivering
- Shortness of breath
- Vomiting blood
- Black, tarry stools
- Episodes of mental confusion or drowsiness
Early diagnosis and management are essential to slow disease progression and prevent complications.
Treating cirrhosis
Treating cirrhosis focuses on managing symptoms, preventing further damage to the liver, and addressing complications as they arise. While it is not possible to cure cirrhosis, early intervention and lifestyle changes can slow down its progression and improve quality of life.
Lifestyle Changes and Prevention of Further Liver Damage
- Avoiding Alcohol: Complete abstinence from alcohol is essential, regardless of the cause of cirrhosis. Alcohol consumption can worsen liver damage, leading to faster progression of the disease.
- Dietary Adjustments:
- Reduce Salt Intake: This can help reduce fluid retention, swelling in the abdomen (ascites), and peripheral edema (swelling in the legs and ankles).
- Balanced Diet: Eat a diet rich in nutrients, protein, and calories, especially if malnutrition is present. Small, frequent meals may help prevent muscle wasting.
- Avoid Raw or Undercooked Shellfish: Reduces the risk of foodborne illnesses.
- Weight Loss: Achieving and maintaining a healthy weight can help manage conditions such as non-alcoholic steatohepatitis (NASH).
- Exercise: Regular exercise can reduce muscle wasting and improve overall strength.
- Quit Smoking: Avoid smoking, which can contribute to overall poor health and worsen cirrhosis.
Medications and Medical Interventions
- Treat Underlying Conditions:
- Viral Hepatitis: Antiviral medications may be prescribed for hepatitis B or C.
- Autoimmune Hepatitis: Treatment may involve corticosteroids and immune-suppressing drugs.
- Diuretics: Used to reduce fluid retention and swelling (ascites and peripheral edema). Common diuretics include spironolactone and furosemide.
- Beta-Blockers: These may help prevent variceal bleeding by reducing blood pressure in the portal vein.
- Lactulose: Helps manage hepatic encephalopathy by removing toxins through increased bowel movements.
- Antibiotics: Used to treat or prevent infections, especially in cases of ascites.
Managing Complications
- Varices: Enlarged veins in the esophagus or stomach that may bleed. Treatments include:
- Banding or Glue Therapy: Endoscopic procedures to stop bleeding.
- TIPSS (Transjugular Intrahepatic Portosystemic Shunt): A stent placed to reduce pressure in the portal vein.
- Beta-Blockers: To lower the risk of variceal bleeding.
- Ascites and Edema: Fluid accumulation treated with dietary salt restriction, diuretics, or draining procedures (paracentesis).
- Encephalopathy: Cognitive issues treated with lactulose syrup and, if necessary, enemas or other laxatives.
- Bleeding: Cirrhosis can impair clotting, increasing the risk of severe bleeding. Vitamin K and plasma transfusions may be necessary.
Advanced Stages and Liver Transplant
- Liver Transplant: For those with severe liver damage or liver failure, a transplant may be the only option. However, it requires a suitable donor and is subject to strict eligibility criteria.
- Managing Complications: Regular follow-ups, monitoring for liver cancer, and comprehensive care from a hepatology team are crucial.
Important Considerations
- Vaccinations: Ensure you are up-to-date with vaccinations, such as for hepatitis A, B, flu, and pneumonia.
- Medications: Some over-the-counter and prescription medications may need adjustment, as the liver’s ability to metabolize drugs is compromised.
- Psychological Support: Chronic conditions like cirrhosis can lead to stress, anxiety, and depression. Joining a support group and accessing counseling may be beneficial.
Emergency Situations
- Seek immediate medical attention if you experience:
- Vomiting blood
- Black, tarry stools
- Shortness of breath
- Fever and shivering attacks
- Confusion or mental changes
Treating cirrhosis requires a multifaceted approach involving lifestyle changes, medications, and regular medical care to manage symptoms, prevent complications, and maintain a good quality of life.
