Exocrine pancreatic insufficiency (EPI) is a condition that happens when there’s a problem with your pancreas, mainly with how well it helps you digest food.
Your pancreas makes enzymes that break down the fats, proteins, and starches you eat so your body can use them. If the organ can’t do its job, you can have digestive and other problems, such as:
Loss of appetite
Loose, pale, oily, foul-smelling stools
