Too much fat in your feces is called steatorrhea. It may be a result of overconsumption of fatty and greasy foods, or it can be a sign of malabsorption. This means your body either isn't absorbing nutrients properly or isn't making the enzymes or bile needed to digest food effectively.

Which is the most common cause of steatorrhea?

Although several conditions can lead to impaired lipid absorption and steatorrhea (excess fat in the feces), the most common causes of steatorrhea are related to bile salt deficiency, pancreatic enzyme deficiency, defective CM synthesis, or lymphatic obstruction.

Why does steatorrhea occur in pancreatitis?

Lack of enzymes due to pancreatic damage results in poor digestion and absorption of food, especially fats. Thus, weight loss is characteristic of chronic pancreatitis. Patients may notice bulky smelly bowel movements due to too much fat (steatorrhea).
