PATHOLOGY

Detailed explanation-1: -In people with chronic pancreatitis, the pancreas may not function normally, leading to difficulty processing fat in the diet (exocrine pancreatic insufficiency). This can cause loose, greasy, foul-smelling stools that are difficult to flush.

Detailed explanation-2: -You can have 2 types of fecal fat tests: qualitative and quantitative. For a qualitative test, the lab checks a single stool sample under a microscope to count the number of fat globules, or droplets. For a quantitative test, you collect stool samples usually over a period of 3 days.

Detailed explanation-3: -Fatty poops are different from normal poops. They tend to be looser, smellier and paler in color, like clay. They might float. You might have an occasional fatty poop after eating a fatty meal.
