EPI is largely a clinical diagnosis1-4*

Patients with EPI may present with signs and symptoms similar to other GI disorders. A careful workup is necessary when suspecting EPI and should include patient history, symptom assessment, and asking about underlying conditions. It's also important to get specific details about GI issues, including symptom onset, frequency, and severity, and patient diet.

*Tests can help confirm a diagnosis.

Evaluate patients for signs and symptoms of EPI

It is key to take a history in your patients suspected of having EPI since not all patients will present with typical signs and symptoms of EPI. Some patients may limit fat intake to minimize symptoms.3,4

Patients with EPI may present with one or more of the following signs and symptoms4-6:

  • Diarrhea
  • Flatulence
  • Bloating
  • Abdominal pain
  • Unexplained weight loss
  • Steatorrhea

Consider EPI in patients with underlying conditions

Know the underlying conditions and surgical procedures that can lead to EPI.

EPI may be present in patients with the following underlying conditions or procedures7-10:

  • Cystic fibrosis (CF)
  • Chronic pancreatitis (CP)
  • Pancreatectomy (PY)
  • Pancreatic cancer

Other underlying conditions and procedures in which EPI has been reported include11-15:

  • Acute pancreatitis (AP)
  • Crohn’s disease
  • Celiac disease
  • Type 1 diabetes
  • Gastric resection/bypass

Ask your patients specific questions to help them open up about their symptoms

Patients may find it difficult to discuss GI issues with their doctor and may be embarrassed to disclose their symptoms. Because EPI is largely a clinical diagnosis, asking specific questions may help you reach a diagnosis sooner.1,16*

Stool Details

  • How would you describe your stool? Is it loose? Does it float? Is it greasy? Is the color pale?
  • Does it smell very foul? Is it difficult to flush?

Other Considerations

  • Have you had any unexplained weight loss?
  • Do you feel like you are managing your symptoms by limiting what you eat?

*Tests can help confirm a diagnosis.

Tests that can help confirm a diagnosis of EPI

Non-invasive measures:

  • Fecal elastase concentration (FE-1)2
  • Qualitative fecal fat18
  • Quantitative fecal fat18

Invasive measures:

  • Secretin-pancreozymin stimulation (performed at specialized centers)1
