Common Liver Diseases and Their Symptoms


Symptoms of liver disease depend on the disorder, but can include:
  • Jaundice (the skin or whites of the eye turn yellow)
  • Dark urine
  • Nausea
  • Vomiting
  • Diarrhoea
  • Appetite loss
  • Weight loss
  • General malaise
  • Fever
  • Bloated abdomen, swollen ankles
  • Abdominal pain in the upper right side
  • Anaemia, vomiting blood or passing black stools (denoting altered blood)
  • Changes in mental state – altered sleep pattern (awake at night), confusion, and drowsiness.

Common Liver Diseases
  • Fatty liver – this is the most common of the alcohol-induced liver disorders. Fat accumulates inside the liver cells, causing cell enlargement (steatosis) and sometimes cell damage (steatohepatitis), and can lead to cirrhosis. Similar changes are also seen in people who do not drink excessive amounts of alcohol but are overweight, obese or have diabetes. The liver becomes enlarged, causing discomfort on the upper right side of the abdomen.
  • Cirrhosis – this has many causes but is commonly due to hepatitis infection or excessive alcohol intake. The cells of the liver are progressively replaced by scar tissue, which seriously impairs liver functioning.
  • Hepatitis – a general term meaning inflammation of the liver. It is also used to refer to infections of the liver by specific viruses (hepatitis A to E).
  • Haemochromatosis – this inherited disease makes the body absorb and store higher than normal amounts of iron. This damages many organs including the liver, pancreas and heart.
  • Autoimmune liver disorders – an abnormal increase in immune cells damages the liver cells. These rare conditions include autoimmune hepatitis and primary biliary cirrhosis (mostly women affected) and primary sclerosing cholangitis (more common in men).
  • Cancer – primary cancers can arise in the liver, most often from chronic hepatitis with cirrhosis. Stray cancer cells from a tumour elsewhere in the body may cause a secondary tumour in the liver.
  • Galactosaemia – the body’s reaction to particular milk sugars damages the liver and other organs. This is a rare inherited disorder.
  • Alpha 1-antitrypsin deficiency – another rare inherited disorder that can cause cirrhosis of the liver.
  • Wilson’s disease – the liver can’t excrete copper. Various organs of the body, including the liver and brain, are affected by the excessively high copper levels.
       
         Complications of liver disease
        Without treatment, a person with liver disease is susceptible to a wide range of complications,               including:


  • Hepatic Encephalopathy – scar tissue prevents the proper flow of blood through the liver, so that toxins remain. These circulating toxins, particularly ammonia, affect brain functioning and can lead to a coma.
  • Ascites – liver disease can cause a build-up of body sodium (‘salt’), which leads to fluid retention in the abdominal cavity (ascites) and in the legs, feet and back (oedema).
  • Liver failure – the liver cells are destroyed faster than the liver can replace them, until the organ can no longer function adequately.
  • Cancer – cirrhosis or some forms of hepatitis can make the liver more susceptible to primary cancer (cancer that originates in the liver).
  • Gastrointestinal bleeding – the veins that normally travel through the liver may be blocked because of cirrhosis. These veins then bypass the liver and may travel along the stomach or oesophagus lining, where they may rupture and bleed.

Precautions to Protect Liver


  • Avoiding alcohol and any drugs that might damage the liver
  • A well-balanced, nutritious diet – some people require a modified diet (for example, low salt)
  • Medications, such as antiviral drugs to treat viral infections
  • Specific medications to manage Wilson’s disease
