Pancreatic Exocrine Deficiency: Identifying Its Causal Factors
Exocrine Pancreatic Insufficiency (EPI) is a digestive condition that can affect a person's ability to absorb nutrients from food. This condition, which can be caused by a variety of factors, is often associated with chronic pancreatitis and cystic fibrosis, but its causes extend far beyond these two conditions.
EPI occurs when the pancreas does not produce enough enzymes or produces defective enzymes, affecting the body's ability to digest food properly. This can lead to malnutrition if left untreated.
People with diabetes, especially those with type 1 or type 2, may be at higher risk of developing EPI. Additionally, surgical removal of benign tumors in the pancreas can improve EPI symptoms. Nearly half of people with cystic fibrosis also have EPI.
Cystic fibrosis, an inherited, progressive condition that causes chronic lung infections, can lead to EPI in some people by causing a buildup of mucus in the pancreas. Chronic pancreatitis, an inflammation in the pancreas that gets progressively worse over time, is the most common cause of EPI.
A mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene can lead to insufficient production or no production of the CFTR protein, which is associated with EPI. Similarly, a mutation in the Serine peptidase inhibitor Kazal type 1 (SPINK1) gene has an association with hereditary pancreatitis, another cause of EPI.
Several other factors and health conditions can cause EPI, including autoimmune conditions, chronic renal failure, hyperlipidemia, hypercalcemia, irregularities and blockages in the pancreas, alcohol and tobacco use, and diabetes.
Non-pancreatic causes that can lead to EPI or contribute to maldigestion include untreated celiac disease, inflammatory bowel disease, hypersecretory states like Zollinger-Ellison syndrome, and prior intestinal surgeries such as Roux-en-Y bypass. Infectious causes—viral, bacterial, or parasitic infections—also can inflame or damage the pancreas, potentially resulting in EPI.
Treatments for EPI include pancreatic enzyme replacement therapy (PERT), provided in the form of prescription pills, and making dietary changes, such as a high-calorie, high-healthy-fat diet for people with cystic fibrosis and EPI. Regular check-ups with a doctor or dietitian are important to ensure EPI treatment is working effectively.
Surgical procedures such as pediatric intestinal transplantation, pancreatic surgery, and gastrointestinal surgery can cause EPI. It's important for individuals who have undergone such procedures to discuss EPI with their healthcare provider.
EPI affects approximately 42 to 73 people per 100,000 in the United States who have been living with chronic pancreatitis for 10 to 12 years. Addressing the underlying condition causing EPI may also help improve symptoms.
In conclusion, EPI is a complex condition with various causes and treatments. By understanding the causes and symptoms of EPI, individuals can take steps to manage the condition effectively and maintain a healthy lifestyle. If you suspect you may have EPI, it's important to consult with a healthcare provider for a proper diagnosis and treatment plan.

- Pancreatic enzyme replacement therapy (PERT) can be beneficial for individuals with Exocrine Pancreatic Insufficiency (EPI), especially those with chronic diseases like cystic fibrosis, as it helps digest food and prevent malnutrition.
- In the context of medical-conditions and chronic diseases, proper nutrition plays a crucial role in managing EPI, making a high-calorie, high-healthy-fat diet essential for patients with cystic fibrosis and EPI.
- Health and wellness awareness about the retargeting risks associated with diabetes and its complications, including Exocrine Pancreatic Insufficiency (EPI), can empower individuals to take active steps in maintaining their health.
- Science continually explores the underlying causes of Exocrine Pancreatic Insufficiency (EPI) and associated conditions, such as the mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene linked to cystic fibrosis and EPI, providing opportunities for innovative treatments in the future.
