Steatosis - Definition

Ask a question


Steatosis is the accumulation of lipids, or fat, in body tissue, primarily concerning triglycerides. The most commonly affected tissue is that of the liver and its cells. Fat building up in cells can lead to their destruction, and the progressive development of liver failure, which can potentially progress to cirrhosis of the liver. There are other types of steatosis, including myocardial steatosis, affecting cardiac muscle tissue; renal steatosis; and pulmonary steatosis. Causes include an overly fatty diet, or alcohol abuse.
