Cirrhosis

What is cirrhosis?

Cirrhosis is advanced scarring of the liver. The liver is a large organ in the upper right part of the abdomen that filters the blood, helps digest food, stores energy, and makes proteins the body needs to clot blood and fight infection. When the liver is injured over many years, it tries to repair itself. Each round of injury and repair leaves behind scar tissue, a process called fibrosis. Cirrhosis is the stage at which this scar tissue has replaced so much healthy tissue that the liver’s structure is changed and its function begins to decline.

Cirrhosis is not a single disease. It is the end result of many different long-term liver conditions. It develops slowly, often over decades, and many people do not know they have it until it is quite advanced. It can affect adults of any age and, less commonly, children with inherited liver disorders. Men and women are both affected, and the most common underlying causes vary from one part of the world to another. In many hospital systems, including Acibadem, cirrhosis is assessed and managed by a gastroenterology or hepatology team. Hepatology is the branch of medicine that focuses on the liver.

Doctors often describe cirrhosis in two broad stages. In compensated cirrhosis, the liver is scarred but still manages to do most of its jobs, and a person may feel well. In decompensated cirrhosis, the liver can no longer keep up, and serious complications begin to appear.

Cirrhosis symptoms

Early cirrhosis frequently causes no symptoms at all. When symptoms do appear, they are often vague and easy to attribute to other things. Common early cirrhosis symptoms include:

• Tiredness or weakness that does not improve with rest
• Loss of appetite and unintended weight loss
• Nausea or mild discomfort in the upper right abdomen
• Small red blood vessels visible on the skin, sometimes called spider angiomas
• Redness of the palms
• Easy bruising or bleeding, because the liver makes fewer clotting proteins
• Itchy skin

As the liver becomes less able to cope, the signs of decompensated cirrhosis may develop. These are the result of two main problems: the liver failing to do its chemical work, and increased pressure in the vein that carries blood from the intestines to the liver, a condition called portal hypertension. Later symptoms may include:

• Jaundice, a yellow color of the skin and the whites of the eyes, caused by a buildup of a yellow pigment called bilirubin
• Swelling of the abdomen from fluid buildup, known as ascites
• Swelling of the legs and ankles, known as edema
• Confusion, drowsiness, slurred speech, or personality changes, known as hepatic encephalopathy, which happens when toxins the liver normally removes reach the brain
• Vomiting blood or passing black, tarry stools, which can signal bleeding from enlarged veins in the esophagus or stomach called varices
• Dark urine and pale stools
• In men, enlarged breast tissue and shrinking of the testicles; in women, irregular or absent menstrual periods

The pattern of symptoms depends partly on the cause. For example, people whose cirrhosis is related to alcohol may also have signs of alcohol-related damage to other organs, while people with cirrhosis caused by bile duct disease may notice intense itching early on. However, once scarring is advanced, the symptoms of different types of cirrhosis tend to look similar, because they all reflect the same loss of liver function.

Cirrhosis causes and risk factors

Anything that repeatedly injures the liver over a long period can lead to cirrhosis. The most common cirrhosis causes worldwide are:

• Long-term heavy alcohol use. Alcohol is broken down in the liver, and large amounts over many years directly damage liver cells.
• Chronic viral hepatitis. Hepatitis B and hepatitis C are viral infections that can persist for decades and cause ongoing inflammation of the liver.
• Fatty liver disease not caused by alcohol. Often linked with obesity, type 2 diabetes, and high cholesterol, this condition is now one of the leading causes of cirrhosis in many countries. It is sometimes called metabolic dysfunction-associated steatotic liver disease.

Less common causes include:

• Autoimmune hepatitis, in which the body’s immune system attacks liver cells
• Diseases of the bile ducts, such as primary biliary cholangitis and primary sclerosing cholangitis, which block or destroy the small tubes that carry bile out of the liver
• Inherited disorders, such as hemochromatosis (too much iron stored in the body), Wilson disease (too much copper), and alpha-1 antitrypsin deficiency
• Long-term use of certain medications or exposure to toxins
• Repeated heart failure that causes blood to back up in the liver
• Certain parasitic infections, more common in some regions

In some people, more than one cause is present at the same time, and the combination speeds up the damage. Occasionally no clear cause is found, which doctors describe as cryptogenic cirrhosis.

Risk factors are things that increase the chance of developing cirrhosis. They include drinking alcohol above recommended limits over many years, being overweight, having type 2 diabetes, living with untreated hepatitis B or C, having a family history of inherited liver disease, and sharing needles or receiving unscreened blood products, which raises the risk of viral hepatitis. Having a risk factor does not mean a person will develop cirrhosis, and some people develop it without any obvious risk factor.

Cirrhosis diagnosis

Because early cirrhosis may cause no symptoms, it is sometimes discovered by chance during tests done for another reason. When a doctor suspects cirrhosis, the diagnosis is usually built up from several pieces of information rather than a single test.

Medical history and physical examination. The doctor will ask about alcohol use, past infections, medications, family history, and symptoms. During the examination, they may feel for an enlarged or hardened liver, an enlarged spleen, fluid in the abdomen, or skin changes such as jaundice and spider angiomas.

Blood tests. Liver function tests measure enzymes and proteins released or made by the liver. In cirrhosis, levels of bilirubin may rise, the protein albumin may fall, and blood clotting may slow. A low platelet count is also common, because portal hypertension causes the spleen to trap platelets. Blood tests can also identify the cause, for example by detecting hepatitis viruses, unusual antibodies, or abnormal iron or copper levels. Several formulas that combine routine blood results are used to estimate how much scarring is likely.

Imaging. An ultrasound scan is often the first imaging test. It can show a shrunken, nodular liver, an enlarged spleen, and fluid in the abdomen. A specialized ultrasound called elastography measures how stiff the liver is; a stiffer liver generally means more scarring. This test is painless and is widely used to assess fibrosis without a biopsy. CT (computed tomography) or MRI (magnetic resonance imaging) scans may be used to look at the liver in more detail and to check for liver tumors.

Endoscopy. A thin flexible tube with a camera may be passed down the throat to look for varices in the esophagus and stomach, since these can bleed.

Liver biopsy. In a biopsy, a small sample of liver tissue is removed with a needle and examined under a microscope. It was once the standard way to confirm cirrhosis. Today it is used less often, mainly when the cause is unclear or when other tests give conflicting results, because imaging and blood tests can frequently provide enough information.

Once cirrhosis diagnosis is confirmed, doctors often use scoring systems, such as the Child-Pugh score or the MELD score, which combine several blood results and clinical findings to describe how severe the liver disease is and to help guide decisions about treatment.

Cirrhosis treatment options

Scar tissue in the liver cannot usually be removed, so the aims of treatment are to stop or slow further damage, manage complications, and, in suitable people, consider a liver transplant. Cirrhosis treatment options are tailored to the cause and stage of disease.

Treating the underlying cause. This is the most important step and may allow the liver to stabilize or even partly recover if the scarring is not too advanced. Depending on the cause, this may involve stopping alcohol completely, antiviral medications for hepatitis B or C, weight loss and control of diabetes for fatty liver disease, medications that suppress the immune system for autoimmune hepatitis, or treatments that remove excess iron or copper in inherited disorders.

Medications for complications. Diuretics, often called water tablets, help the body get rid of excess fluid that causes ascites and leg swelling, usually alongside a reduced-salt diet. Beta-blockers, a type of blood pressure medication, may be prescribed to lower pressure in the varices and reduce the risk of bleeding. Laxatives and certain antibiotics are used to reduce the toxins that cause hepatic encephalopathy. Antibiotics may also be given to prevent or treat infections, which people with cirrhosis are more prone to.

Procedures. If varices are large or have bled, a doctor may place small rubber bands around them during an endoscopy to make them close off, a procedure called band ligation. If fluid in the abdomen becomes uncomfortable, it can be drained with a needle in a procedure called paracentesis. In some cases, a procedure known as TIPS (transjugular intrahepatic portosystemic shunt) creates a channel inside the liver to relieve portal hypertension.

Surgery and liver transplant. For people whose liver is failing despite other treatments, a liver transplant may be the only option that restores liver function. In this operation, the diseased liver is replaced with a healthy liver from a deceased donor or part of a liver from a living donor. Not everyone is a suitable candidate, and careful assessment is required. Where transplant is considered, it is usually coordinated by a specialist hepatology and transplant team.

Monitoring and supportive care. People with cirrhosis are generally offered regular checks for liver cancer, typically with ultrasound every six months, because cirrhosis raises the risk of a liver tumor called hepatocellular carcinoma. Vaccination against hepatitis A and B, influenza, and pneumococcal infection is often recommended. A dietitian may help with nutrition, since muscle loss and malnutrition are common. Some medications, including certain painkillers and herbal supplements, can be harmful to a damaged liver, so all medicines should be reviewed with the care team.

Living with cirrhosis and outlook

The outlook for a person with cirrhosis varies widely and depends on the cause, how advanced the scarring is, whether complications have developed, and whether the cause can be controlled. Many people with compensated cirrhosis who stop the injury to their liver live for many years with a good quality of life. Once decompensation occurs, the condition is more serious, and the risk of life-threatening complications rises. Doctors use severity scores to give a clearer picture of an individual’s situation, but no one can predict exactly how the disease will progress for a particular person.

Day-to-day, living with cirrhosis usually involves avoiding alcohol entirely, following a balanced diet with enough protein and limited salt, staying physically active where possible, keeping up with regular appointments and scans, and taking medications as prescribed. It also means paying attention to new symptoms such as confusion, increasing swelling, or fever, since early treatment of complications tends to lead to better results. Emotional wellbeing matters too; living with a long-term condition can be stressful, and support from family, friends, or counseling may be helpful.

Frequently asked questions

What is cirrhosis in simple terms?

Cirrhosis means the liver has become heavily scarred after years of injury. Scar tissue replaces healthy tissue, the liver becomes hard and lumpy, and it gradually loses its ability to clean the blood, make proteins, and help with digestion. It is the late stage of many long-term liver diseases rather than a disease in its own right.

What are the first cirrhosis symptoms people notice?

In many cases there are no early symptoms at all. When symptoms do occur, the first ones are often tiredness, poor appetite, weight loss, nausea, and easy bruising. Because these are common and nonspecific, cirrhosis is frequently found during routine blood tests or scans rather than because of symptoms. Yellowing of the skin, abdominal swelling, and confusion usually appear later.

What are the most common cirrhosis causes?

The leading causes are long-term heavy alcohol use, chronic hepatitis B or C infection, and fatty liver disease linked with obesity and diabetes. Less common causes include autoimmune diseases, bile duct disorders, and inherited conditions that cause iron or copper to build up in the liver. Sometimes several causes act together.

How is cirrhosis diagnosis confirmed?

Doctors usually combine a physical examination, blood tests that show how the liver is working, and imaging such as ultrasound or elastography to measure liver stiffness. Endoscopy may be used to look for enlarged veins in the esophagus. A liver biopsy is now needed less often but may be done when the cause or the degree of scarring is uncertain.

Can cirrhosis be reversed?

Established scar tissue generally does not disappear, so cirrhosis is usually considered permanent. However, if the underlying cause is treated early, for example by stopping alcohol or curing hepatitis C, the liver may stop getting worse and in some cases improve its function. This is why early diagnosis and treatment of the cause are so important.

What cirrhosis treatment options are available if the liver is failing?

When the liver can no longer cope despite medications and procedures, a liver transplant may be considered. This involves a thorough assessment of overall health and, in the case of alcohol-related disease, a period of confirmed abstinence. Not everyone is eligible, and availability of donor organs varies. Your doctor can explain whether referral for transplant assessment is appropriate in your situation.

When to see a doctor

If you have ongoing tiredness, unexplained weight loss, yellowing of the skin or eyes, or a known risk factor such as heavy alcohol use, viral hepatitis, or fatty liver disease, it is reasonable to ask a doctor about a liver check. Early detection gives the widest range of treatment options.

Some symptoms in a person with known or suspected cirrhosis are medical emergencies. Seek urgent medical care if you or someone you care for experiences:

• Vomiting blood or material that looks like coffee grounds
• Black, tarry, or bloody stools
• Sudden confusion, extreme drowsiness, difficulty waking, or unusual behavior
• Rapidly increasing swelling of the abdomen, especially with pain or fever
• Fever or chills, which may signal a serious infection
• Severe shortness of breath
• Very little or no urine over a day
• New or worsening jaundice with severe weakness

These warning signs can indicate bleeding, infection, kidney problems, or hepatic encephalopathy, all of which need prompt assessment and treatment in a hospital setting.
