Exocrine Pancreatic Insufficiency
Exocrine pancreatic insufficiency (EPI) means the pancreas does not release enough digestive enzymes. Poor digestion can cause greasy stools, bloating, weight loss and vitamin deficiencies.
Key takeaways
- Greasy, pale or difficult-to-flush stools and unexplained weight loss are important clues, but testing is needed to confirm the cause.
- Pancreatic enzyme replacement helps digest food; it does not treat the pancreatic disease or surgery that caused EPI.
- Ongoing symptoms may require checks of nutrition, vitamin levels and whether enzyme treatment is working as intended.
Enzyme listings are relevant only after EPI is assessed; similar symptoms can result from coeliac disease, bile problems and other digestive conditions.
How is EPI assessed?
Symptoms, weight change and medical history guide testing. Chronic pancreatitis, cystic fibrosis and pancreatic surgery are common contexts. Stool tests can help evaluate enzyme output, while blood tests may identify malnutrition or deficiencies in vitamins A, D, E and K.
What does enzyme replacement do?
Pancrelipase supplies lipase, amylase and protease in the gut. A clinician tailors treatment to food intake and response, and investigates persistent symptoms rather than assuming more enzyme is always the answer. Nutritional support and management of the underlying condition remain important parts of digestive health care.
When to seek urgent care
Seek urgent help for severe or rapidly worsening upper-abdominal pain, repeated vomiting, inability to keep fluids down, black or bloody stools, fainting, or yellowing of the skin or eyes.
