The new survey shows, that 74 percent of Americans have digestive symptoms like diarrhea, gas, bloating and abdominal pain. But what many people may not know is that these symptoms could indicate a more serious condition: celiac disease, Crohn’s disease, EPI or exocrine pancreatic insufficiency.

EPI is a condition where the pancreas does not function properly, failing to produce the enzymes needed for digestion. It’s often associated with other underlying health issues like chronic pancreatitis, pancreatic cancer or diabetes, Fox News reports.

Because many patients are embarrassed to discuss digestive issues with their doctor, they often go undiagnosed, which can lead to further complications.
