Cirrhosis is often shrouded in stigma and misunderstood as a condition solely caused by alcohol misuse. In reality, it is the advanced stage of various chronic liver diseases. It represents a point where the liver has been so heavily scarred that it struggles to perform its 500+ vital functions, making early detection and management absolutely critical.
Cirrhosis is not a disease in itself, but the result of long-term damage. When the liver is injured—by toxins, fat, or viruses—it tries to repair itself, creating scar tissue (fibrosis). Cirrhosis occurs when this scarring becomes so extensive that the liver’s structure is permanently altered, blocking blood flow and hindering function.
While long-term alcohol misuse is a well-known cause, it is far from the only one. Other leading causes in the UK include:
Non-alcoholic fatty liver disease (NAFLD): Now increasingly common due to obesity and type 2 diabetes.
Chronic Viral Hepatitis: Specifically Hepatitis B and C.
Autoimmune conditions: Such as Primary Biliary Cholangitis (PBC).
One of the most dangerous aspects of cirrhosis is that it often has no symptoms in the early stages (known as compensated cirrhosis). The liver is incredibly resilient and can continue to function even when significantly scarred. Often, people only discover they have a liver issue during routine blood tests for unrelated problems.
As the liver begins to fail (decompensated cirrhosis), symptoms become more apparent and serious. These can include:
Jaundice: Yellowing of the skin and the whites of the eyes.
Oedema and Ascites: Swelling in the legs or a build-up of fluid in the abdomen.
Easy bruising and bleeding: Because the liver can no longer produce enough clotting proteins.
When the liver cannot filter toxins (like ammonia) from the blood, these toxins can travel to the brain. This causes Hepatic Encephalopathy, which ranges from mild confusion and “brain fog” to personality changes, extreme sleepiness, and in severe cases, coma.
Patients with cirrhosis have a significantly higher risk of developing Hepatocellular Carcinoma (HCC), the most common type of primary liver cancer. Because of this, patients with a cirrhosis diagnosis usually require “surveillance”—an ultrasound scan and blood tests every six months.
Scarring restricts blood flow through the liver, increasing pressure in the portal vein. This “backlog” of pressure can cause veins in the oesophagus (food pipe) and stomach to swell. These are called varices, and they are prone to bursting, which causes life-threatening internal bleeding.
While blood tests (Liver Function Tests) provide clues, they don’t always show the full picture of scarring. Doctors now commonly use a FibroScan, a non-invasive ultrasound that measures the “stiffness” of the liver. The stiffer the liver, the more likely it is that cirrhosis is present.
It was traditionally taught that cirrhosis is completely irreversible. However, medical understanding is evolving. If the underlying cause (such as alcohol or a virus) is removed or treated early enough, the liver has a remarkable ability to heal, and some “stiffness” or fibrosis can actually regress over time.
When the liver reaches a stage where it can no longer support life, a liver transplant may be the only option. However, many people manage cirrhosis for decades through lifestyle changes, medications to manage symptoms, and strict avoidance of further liver toxins (like alcohol and certain over-the-counter painkillers).
MyHSN Top Tip: Many liver conditions are reversible if caught at the “fatty liver” or early fibrosis stage. If you have risk factors like heavy alcohol intake, type 2 diabetes, or being overweight, ask your GP for a Liver Function Test or a FibroScan to check your liver health before symptoms appear.
