Exocrine Pancreatic Insufficiency

Key facts

• Exocrine pancreatic insufficiency (EPI) means the pancreas fails to produce enough digestive enzymes to break down food properly. Fats, proteins and carbohydrates pass through the gut largely undigested.
• The clearest sign is steatorrhoea: loose, pale, greasy stools that are hard to flush and have a strong odour, often with weight loss and bloating.
• Treatment centres on pancrelipase, an enzyme replacement taken with every meal and snack. It is the main option under digestive health for EPI.
• See a doctor for new or worsening symptoms, unexplained significant weight loss, or persistent pain.

What it looks and feels like

The most telling sign is steatorrhoea: loose, pale, greasy stools that are difficult to flush and have a strong odour. Weight loss despite eating normally, bloating after meals, and cramping are common. Nutritional deficiencies, particularly of fat-soluble vitamins A, D, E and K, can develop over time and cause fatigue or bone pain.

How EPI is treated

Treatment centres on replacing the missing enzymes. Pancrelipase is the standard enzyme preparation, taken with each meal and snack to restore normal digestion. It supplies lipase, amylase and protease directly in the gut where they are needed, and sits within digestive health as the main option for EPI. Dose is adjusted to stool response, and many people see a clear improvement in stool consistency and weight within weeks.

Underlying causes

Chronic pancreatitis, cystic fibrosis, and prior pancreatic surgery are common underlying causes and should be addressed alongside enzyme therapy rather than left untreated.

When to see a doctor

See a doctor for new or worsening symptoms, unexplained significant weight loss, or persistent pain, since these need review beyond enzyme replacement alone.
