Fatty liver disease can occur in pets such as reptiles (particularly turtles [48]) and birds [49] as well as mammals like cats and dogs. [50] The most common cause is overnutrition. A distinct sign in birds is a misshapen beak. Fatty livers can be induced via gavage in geese or ducks to produce foie gras. Fatty liver can also be induced in ...
Hepatomegaly is enlargement of the liver. [4] It is a non-specific medical sign , having many causes, which can broadly be broken down into infection , hepatic tumours , and metabolic disorder . Often, hepatomegaly presents as an abdominal mass .
Steatosis, also called fatty change, is abnormal retention of fat within a cell or organ. [1] Steatosis most often affects the liver – the primary organ of lipid metabolism – where the condition is commonly referred to as fatty liver disease. Steatosis can also occur in other organs, including the kidneys, heart, and muscle. [2]
Risk Factors for Fatty Liver Disease. Having overweight or obesity is a major risk factor for fatty liver disease. Estimates suggest that up to 75 percent of people with overweight have NAFLD, and ...
Hepatosplenomegaly (commonly abbreviated HSM) is the simultaneous enlargement of both the liver (hepatomegaly) and the spleen (splenomegaly).Hepatosplenomegaly can occur as the result of acute viral hepatitis, infectious mononucleosis, and histoplasmosis or it can be the sign of a serious and life-threatening lysosomal storage disease.
In people with fatty liver with associated inflammatory injury (steatohepatitis) blood tests are usually used to rule out certain types of viral hepatitis and autoimmune diseases. Low thyroid activity is more prevalent in people with NASH, which would be detected by determining the thyroid-stimulating hormone . [ 68 ]
Steatohepatitis is a type of fatty liver disease, characterized by inflammation of the liver with concurrent fat accumulation in liver. Mere deposition of fat in the liver is termed steatosis, and together these constitute fatty liver changes. [1] There are 2 main types of fatty liver disease (FLD):
Focal fatty liver (FFL) is localised or patchy process of lipid accumulation in the liver. [1] It is likely to have different pathogenesis than non-alcoholic steatohepatitis which is a diffuse process. FFL may result from altered venous flow to liver, tissue hypoxia and malabsorption of lipoproteins.
