A fatty liver is a condition in which there is an excessive accumulation of fat in the liver. This can lead to inflammation and damage to the liver, and can eventually lead to liver failure. There are a number of ways to check for fatty liver, including blood tests, imaging tests, and liver biopsy.
Blood tests can measure the levels of liver enzymes in the blood. Elevated levels of liver enzymes can indicate liver damage, including fatty liver. Imaging tests, such as ultrasound and MRI, can create images of the liver and show the presence of fat. A liver biopsy is a procedure in which a small sample of liver tissue is removed and examined under a microscope. This can provide a definitive diagnosis of fatty liver.
