Fatty Liver

Fatty liver (steatosis ) is a condition where excess fat is deposited on this organ. This condition happens when more than 5- 10 percent of the weight of the liver is made up of fat.
It can occur at all ages but most common in the age group of 40–50 years Obesity and diabetes are common predisposing factors.

Types of Fatty Liver

  1. Alcoholic fatty liver: This condition occurs when there is a heavy consumption of alcohol. If the patient doesn’t stop taking alcohal, then liver cirrhosis may develop. Treatment is complete abstention from alcohol.
  2. Non alcoholic fatty liver (NAFL): One may develop a fatty liver even if one is not an alcoholic. The liver in some cases is unable to process the fat in cells causing them to build-up on the organ.
     

    When more than 10% of the liver is made of fat then this condition is called Non Alcoholic Fatty Liver (NAFL).
     

    Non alcoholic steatohepatitis (NASH): When fatty liver is associated with inflammation in liver patient is said to be having Non alcoholic steatohepatitis and has a higher risk of progressing to liver cirrhosis or hepatocellular carcinoma (HCC). These condition display symptoms like jaundice, vomiting, nausea, loss of appetite and abdominal pain. Blood test (LFT) shows raised enzymes level. Approx 5-8% of the Indian population has NASH. Consult a doctor if you are experiencing any of these symptoms.

  3. Fatty liver during pregnancy: Occurs mainly in the third trimester.

 

Symptoms
During the early stages (fatty liver) of the disease, patients usually have no symptoms directly related to liver disease. However, people may experience a vague abdominal discomfort. If their liver is inflamed (NASH) then they may display symptoms of poor appetite, weight loss, pain in the abdomen and disorientation.
 

What causes fatty liver?
The most common cause of fatty liver is alcoholism. When the human liver is unable to metabolize fat fast enough or when there is an excess accumulation of fat on the liver cells then the liver becomes fatty. However, intake of high-fat foods may not result in a fatty liver.
