What is Fatty Infiltration in the Liver?

Fatty Liver is also known as Steatosis. It is the accumulation of the fat in the liver cells. The fats are stored by the liver in the cytoplasm of the cells. Under normal condition, only 5% of the triglycerides are found in the liver. When the concentration go beyond this limit, it becomes a problem. This is known as fatty infiltration of the liver. Patients do not tend to show any particular symptoms but it is caused due to various reasons.

Causes of Fatty Infiltration in the Liver

  • Increase in the amount of fat transferred to the liver from different parts of the body is the main cause of the fatty infiltration.
  • Intake of alcohol could also lead to fatty infiltration.
  • Starving, obesity, malnutrition and diabetes can also cause fatty infiltration in the liver.

Symptoms of Fatty Infiltration Liver

Liver plays a vital role in the proper functioning of the body, and these functions get disturbed due to the accumulation of fat as in the condition of fatty liver. According to a study conducted by the journal called “Obesity”, above 10% of Americans are suffering from fatty liver. Usually the patients with fatty liver are asymptomatic but, there may be some visible symptoms depending on the stages of the disease.

  • According to the American Liver Foundation, liver enlargement can be noticed while undergoing routine blood tests and X-rays.

Abdominal Pain, Fatigue and Weakness

  • Patients usually report this after the liver enlargement has been noticed.
  • Abdominal Pain and malaise are also common in fatty liver patients.
  • This pain gets noticeable only after the patient gets diagnosed.

Metabolic Syndrome

  • Metabolic syndrome has many risk factors including high blood pressure, excessive abdominal fat and blood fat levels.
  • Metabolic syndrome cannot be said to be a direct symptom of fatty liver but, it is strongly associated with fatty liver.
  • Fatty liver patients are more likely to have it as a metabolic syndrome.

Non-Alcoholic Steatohepatitis (NASH)
Most common form of non-alcoholic fatty liver disease, it affects 2 to 5 percent of the Americans. NASH patients have liver inflammation due to fat accumulation and untreated NASH can lead to cirrhosis. If treated properly this condition is reversible.

If the inflammation is left untreated for years, it leads to cirrhosis. In this stage the liver gets scar tissues and severe inflammation. A liver with cirrhosis will encounter progressive and irreversible damage.

Diagnosis of Fatty Liver Disease Symptoms

  • Ultrasound technique can show the accumulation of fat in the liver. Here, sound waves are directed towards an organ and the reflected waves are captured to obtain a picture of the organ.
  • The extent of fat in liver and severity caused by inflammation can be precisely known through a biopsy. It involves examination of the liver tissue under the microscope. Possibilities of other complications are also revealed by this effective and widely accepted diagnostic technique.
  • Fibrotest and steatotest are a couple of not so widely adopted techniques of diagnosis. Blood tests reveal the count of red blood cells, glucose levels, albumin protein levels and the state of the kidneys. Though liver plays a vital role in the production of essential proteins, kidneys separate these proteins from the waste products of the body before excretion.
