Signs of Cancer in Women: Symptoms You Can't Ignore

Yellow, greasy, and foul smelling stool

There are a variety of reasons why stool will be yellow, greasy, and foul smelling. It can be due to the intestine's inability to digest and absorb fat because of diseases of the intestinal lining (such as in celiac disease and cystic fibrosis) because the pancreas is unable to manufacture adequate digestive enzymes (such as with chronic pancreatitis or pancreatic cancer that blocks the pancreatic duct, or there is not enough bile being delivered to the intestine (such as in cancer of the liver or bile ducts that are blocked). The yellowness, greasiness, and foul smell is due to the undigested fat.
