Pancreatic function testing is a set of tests that check how well your pancreas is working. The pancreas is a small organ behind your stomach that makes enzymes to digest food and hormones like insulin to control blood sugar. These tests measure whether your pancreas is producing enough of these substances.
Key facts
Pancreatic function testing is not a routine test for everyone. It is usually ordered when a doctor suspects a problem with the pancreas, such as pancreatitis (inflammation) or pancreatic insufficiency (not making enough enzymes).
It can be recommended for people of any age who have symptoms of pancreatic disease. This includes adults with chronic pancreatitis, cystic fibrosis, or diabetes, and sometimes children with digestive issues.
Your doctor will start by asking about your symptoms and medical history. They may order a stool test to measure the amount of fat, or a blood test to check for pancreatic enzymes. Sometimes a breath test or an imaging scan like an MRI or CT scan is done. The exact test depends on what your doctor suspects.
Most tests are straightforward. For a stool test, you collect a small sample of your bowel movement at home and send it to a lab. For a breath test, you may be asked to drink a special liquid and then breathe into a bag at certain times. Blood tests are like any other blood draw. Your doctor will give you specific instructions, such as not eating for a few hours before some tests.
If your pancreatic function test shows that your pancreas is not working well, treatment depends on the underlying cause. The goal is to replace missing enzymes, manage symptoms, and treat any root problem like inflammation or diabetes.
Your doctor may prescribe pancreatic enzyme replacement therapy (PERT) – these are pills that you take with meals to help digest food. They are not specific brand-name drugs but a class of medication. You may also need insulin or other diabetes medicines if your blood sugar is affected. Pain medications and anti-inflammatory treatments might be used for pancreatitis. Always follow your doctor's instructions carefully.
Living with a pancreas problem means managing your diet, taking your medications as prescribed, and watching for changes in your symptoms. Many people learn to plan their meals and snacks with enzyme pills. Over time, you can adjust to a new routine that works for you.
A dietitian can help you create a meal plan that is low in fat and rich in nutrients. You may need to limit fried foods, fatty meats, and full-fat dairy. Eat plenty of fruits, vegetables, whole grains, and lean protein like chicken or fish. Exercise should be gentle and not cause belly pain – walking, swimming, or yoga are good options.
You cannot always prevent pancreatic problems, but you can lower your risk. Avoid heavy alcohol use, do not smoke, and maintain a healthy weight. If you have a family history or a condition like cystic fibrosis, work closely with your doctor to monitor your pancreas.
With proper diagnosis and treatment, most people with pancreatic insufficiency can manage their symptoms and live a full life. Enzyme replacement therapy and lifestyle changes can make a big difference. Even if the pancreas is damaged, many people find ways to eat well and stay active. Your healthcare team will help you every step of the way.

Surgery is not common for pancreatic function problems alone, but it may be needed if there is a blockage, a cyst, a tumor, or complications of chronic pancreatitis that do not improve with other treatments.
Living with a chronic pancreas condition can be stressful and may affect your mood. You might feel worried about your health or frustrated with dietary restrictions. It is important to talk about your feelings with your doctor, a counsellor, or a support group. Taking care of your mental health is just as important as physical care.
