Exocrine pancreatic insufficiency (EPI) is a condition in which your small intestine can’t digest food completely because of problems with digestive enzymes from your pancreas. EPI often develops slowly, over many years.
The pancreas is a large gland behind your stomach. The pancreas is both
The pancreas delivers the digestive juice to the small intestine through a single duct. In the small intestine, the enzymes from the pancreas help digest food, breaking down carbohydrates, fats, and proteins.
You may develop EPI if
EPI is rare. However, problems with enzymes from the pancreas occur more often in people with certain health conditions.
Although study results vary, experts think problems with enzymes from the pancreas may occur in
Less commonly, problems with enzymes in the pancreas may occur in people who have
People who have advanced pancreatic diseases are more likely to develop EPI. For example, EPI is more common in people who have
In EPI, the small intestine doesn’t digest food as it should and may not absorb enough nutrients—a condition called malabsorption. EPI and malabsorption can lead to complications such as
Symptoms of exocrine pancreatic insufficiency (EPI) may include
In rare cases, EPI may lead to problems seeing at night or problems with your bones, such as low bone mass or osteoporosis.
To diagnose exocrine pancreatic insufficiency (EPI), your doctor will ask about your medical and family history, perform a physical exam, and order tests.
To help diagnose EPI, your doctor will ask about your
During a physical exam, your doctor may
Doctors most often order stool tests, blood tests, and sometimes pancreatic function tests to diagnose EPI. Doctors may order additional tests to check for diseases that can cause EPI, if the cause is unknown.
Stool elastase test, also called fecal elastase-1 or FE-1 test, is the most commonly used stool test. Low levels of FE-1 in the stool may be a sign of EPI. Your doctor will give you a container for catching and holding a stool sample. You should provide a solid or semisolid stool sample for this test. You will receive instructions on where to send or take the kit for testing.
A health care professional will take a blood sample from you and send the sample to a lab. Doctors may use blood tests to check for low levels of fat-soluble vitamins and minerals or other signs of malnutrition.
Your doctor may order a pancreatic function test to measure how your pancreas responds to secretin, a hormone made by the small intestine. The test measures pancreatic fluid instead of pancreatic enzymes and may not accurately diagnose EPI. This test is done only at some centers in the United States.
During a pancreatic function test, health care professionals give you intravenous (IV) secretin and insert a tube through your nose and into your small intestine. Health care professionals will collect fluid samples with the tube and send the samples to a lab for analysis.
In some cases, doctors use upper gastrointestinal (GI) endoscopy to perform part or all of this test.
Doctors treat exocrine pancreatic insufficiency (EPI) with pancreatic enzyme replacement therapy (PERT) and lifestyle changes.
Doctors may recommend additional treatments for the diseases or conditions that cause EPI.
To treat EPI, doctors typically prescribe PERT. PERT involves taking pills that contain pancreatic enzymes. PERT can improve your symptoms and help you get enough nutrients from what you eat and drink.
PERT is taken during meals or snacks to help your small intestine with digestion. Follow your doctor’s instructions about how and when to take PERT.
Lifestyle changes can also help treat EPI. Your doctor may recommend you
If you have EPI, your doctor may order tests to check for complications, such as
Doctors may recommend you take dietary supplements of fat-soluble vitamins or other nutrients to help prevent or treat these complications.
For safety reasons, talk with your doctor before using dietary supplements, such as vitamins, or any complementary or alternative medicines or medical practices.
If you have exocrine pancreatic insufficiency (EPI), your small intestine can’t digest food normally because of problems with enzymes produced by the pancreas. When the small intestine doesn’t digest food as it should, it may not absorb enough nutrients—a condition called malabsorption.
Malabsorption can lead to
EPI treatment can help correct malabsorption.
Your doctor may refer you to a registered dietitian to help you create a healthy meal plan. Check on the cost of a dietitian’s services and whether your health insurance may pay for some or all of these services.
Your doctor or dietitian may recommend changes to eating and nutrition, such as
Your doctor or dietitian may recommend additional changes to eating, diet, and nutrition to treat the cause of EPI.
