Symptoms of EPI are similar to those of other conditions that affect your stomach and digestion

Many people do not realize that the pancreas plays an important role in digestion and that problems with the pancreas can result in digestive issues. When you have EPI (exocrine pancreatic insufficiency), your body is missing the enzymes it needs to digest food, which causes important nutrients to pass through the body unabsorbed. Malabsorption can lead to a number of signs and symptoms that may vary from person to person. If you have one, some, or all of the symptoms listed below, be sure to talk to your doctor.

EPI symptoms may include:

Unexplained weight loss

EPI affects protein and carbohydrate digestion, but the greatest impact comes from fat maldigestion, which is the primary cause of weight loss in people with EPI. While it may not seem serious, it’s important to tell your doctor if you’re losing weight and don’t know why. This weight loss can be a sign of EPI or another medical condition.

Foul-smelling, oily stools (steatorrhea)

Steatorrhea is a type of bowel movement that is oily, floats, smells really bad, and is difficult to flush. People with EPI are not able to absorb all the fat that they eat, so undigested fat is excreted, resulting in stools that look oily or greasy. Not all people experience this symptom.
