Steatorrhoea is the formation of bulky, grey or pale
faeces. Stools may also float (due to excess gas from carbohydrate
malabsorption), have an oily appearance or be foul smelling. There is increased
fat excretion, which can be measured by determining the faecal fat level. While definitions have not been standardised, fat excretion in faeces in excess of 0.3 (g/kg)/day is considered indicative of steatorrhoea. Possible causes can be lack of
bile acids (due to liver damage or hypolipidemic drugs), defects in pancreatic juices (enzymes) and defective mucosal cells.
