Exocrine pancreatic insufficiency (EPI) is caused by a problem with the pancreas, an organ that plays an important role in digestion. EPI can be difficult to recognize, but once it’s identified, it can be treated.
Read below for information about exocrine pancreatic insufficiency (EPI), including:
Exocrine pancreatic insufficiency is caused by a problem with the pancreas, an organ that plays an important role in digestion.
Normally, the pancreas produces enzymes (substances that trigger chemical reactions in the body) that break down food and allow it to be absorbed. If the pancreas can’t provide these enzymes or they don’t work normally, digestion and absorption cannot happen as they should. This can lead to troublesome symptoms, even malnutrition.
Symptoms of EPI are similar to other digestive problems, so the condition can be difficult to recognize. Once it is identified, though, it can be treated.
After a diagnosis has been made, you and your health care provider can discuss a treatment plan that will help you feel better. This plan may include taking enzymes to replace those that the pancreas is no longer providing. These enzymes allow food to be digested and nutrients to be absorbed into the body. Eating a nutritious diet and taking supplements may also be advised.
EPI often results from damage to the pancreas from diseases such as chronic pancreatitis, pancreatic cancer or cystic fibrosis. Removal of some or all of the pancreas or surgery to other parts of the digestive tract (such as the intestines or stomach) may also cause it.
EPI symptoms can range from mild to severe.
The most common symptoms include:
If EPI is suspected, certain tests may be done to help diagnose it. You and your health care provider can discuss which tests are needed and in what order.
Below are some tests that are used to help in the diagnosis of EPI. If you take any medications, you may be asked to stop using them for a time before these tests. For tests that require stool samples, you will be given instructions for how best to collect them. You will likely be given a device to collect the sample and a special container to put the sample in. Be sure not to get any toilet paper, toilet water or urine in the stool sample.
This test is done to look for an enzyme called elastase that is released from the pancreas during digestion. Normally, this enzyme will be found in stool. If little or none is found, it can be a sign of EPI.
For this test, you will be asked to collect one sample of formed stool to send to a lab. The amount of elastase in the stool is then measured. Only formed stool should be used (no liquid stool). If liquid stool is submitted, this test may not be accurate, because dilution can cause the result to appear falsely abnormal.
Too much fat in the stool is a sign that food is not being broken down and absorbed properly. There are two kinds of fecal fat tests.
When food enters the duodenum from the stomach, a hormone called secretin is released. This hormone triggers the pancreas to send digestive enzymes into the duodenum. The secretin stimulation test checks whether the pancreas has a normal response to secretin.
During the test, secretin is given by intravenous (IV) line. Then, fluid from the duodenum is collected and tested. The fluid is most commonly collected during a procedure called endoscopy. If you have this test, your health care provider can tell you more about how it will be done.
The main treatment for EPI is replacing the enzymes that are no longer provided by the pancreas. This is called pancreatic enzyme replacement therapy (PERT).
PERT involves taking pancreatic enzymes with every meal and snack. These digest the food you eat so you no longer experience symptoms.
To get the most out of PERT, follow all the instructions you are given, including the following:
Even with treatment, the body may still have trouble absorbing certain nutrients, causing vitamin and mineral deficiencies. In these cases, vitamin and mineral supplements may be needed. Talk with your health care provider about whether you need supplements.
