12029 Pancreas Function Tests

Overview

Pancreas function tests are a group of checks that help show how well your pancreas is working. The pancreas is a gland behind the stomach that makes digestive juices and hormones, including insulin, which helps control blood sugar. These tests are not a single diagnosis. They can be blood tests, stool tests, or imaging scans. Your doctor uses the results together with your symptoms, exam, and health history to decide what may be happening. Only a qualified healthcare professional can explain what your results mean for you.

Yes. These tests are fairly common in general practice, especially when someone has ongoing belly pain, greasy stools, weight loss, or blood sugar problems.

Anyone can need pancreas function tests. They are used more often in people with ongoing belly or back pain, greasy or pale stools, unexplained weight loss, diabetes, gallstones, cystic fibrosis, or a family history of pancreas problems.

Symptoms

Common symptoms

• Ongoing pain in the upper belly that may spread to the back
• Greasy, pale, floating stools that are bulky or hard to flush away
• Losing weight without trying
• Poor appetite, nausea, bloating, or feeling full quickly
• New diabetes or blood sugar that is hard to control
• Tiredness or feeling weak, especially if food is not being digested well

Symptoms in children

• Poor weight gain or growth
• Oily or greasy stools, or frequent loose stools
• Belly pain that keeps coming back
• Poor appetite or feeding problems

Symptoms in older adults

• Weight loss or poor appetite
• New diabetes or changing blood sugar control
• Tiredness and weakness
• Belly pain that may be mild or less obvious
• Greasy stools or changes in bowel habits

Causes

Main causes

• Sudden inflammation of the pancreas, called acute pancreatitis
• Long-term inflammation of the pancreas, called chronic pancreatitis
• Gallstones blocking the tubes that drain the pancreas
• Alcohol-related damage to the pancreas
• Cystic fibrosis, an inherited condition that can affect the pancreas
• Diabetes or other problems with blood sugar control
• High levels of fats in the blood, called triglycerides
• Inherited conditions that affect how the pancreas works
• Some infections or medicines can affect the pancreas, but this is less common

Risk factors

• Having gallstones
• Heavy or long-term alcohol use
• Smoking
• High triglyceride levels
• A family history of pancreas problems
• Cystic fibrosis or other inherited conditions
• Obesity
• Diabetes
• Taking medicines that can affect the pancreas, as advised by your doctor

When to see a doctor

See a doctor urgently if:

• You have severe or worsening belly pain
• You cannot keep fluids down or feel dehydrated
• You notice yellowing of your skin or eyes
• Your stools are pale and your urine is dark
• You have a fever with belly pain

Book a routine appointment if:

• You have ongoing belly pain or back pain
• Your stools look greasy, pale, or float
• You are losing weight without trying
• You have new blood sugar problems
• You have a family history of pancreas problems and want advice

Diagnosis

Your doctor will ask about your symptoms, health history, medicines, alcohol use, and family history. They may examine you and arrange blood tests, stool tests, or scans. The results are looked at together, not on their own.

Tests that may be done

• Blood tests for enzymes made by the pancreas, such as amylase and lipase
• Blood tests for blood sugar, such as glucose or HbA1c
• Stool tests to check for fat or a digestive enzyme called elastase
• Ultrasound scan of the belly
• CT scan or MRI scan, sometimes with a special dye
• Other tests if your doctor needs more detail, such as a sweat test for cystic fibrosis

What to expect at your appointment

Most tests are quick and simple. Blood tests take a few minutes. You may need to collect a stool sample at home and bring it to the clinic. Some scans may ask you not to eat or drink for a few hours beforehand. Results can take a few days. Your doctor or nurse will explain the results and next steps.

Treatment

Treatment depends on the cause of your symptoms, not on the test result alone. The aim is to relieve symptoms, help your body digest food, and treat any underlying problem. Your doctor will make a plan with you.

Self-care at home

• Keep a note of your symptoms, meals, and bowel changes to share with your doctor
• Stay hydrated, especially if you have vomiting or diarrhoea
• Eat small, regular meals if large meals make you feel bloated or uncomfortable
• Avoid or limit alcohol
• Do not smoke, and ask for help to stop if you need it
• Ask your pharmacist or doctor before taking any new medicines or supplements

Medical treatments

Your care team may suggest pain relief, enzyme supplements if your pancreas is not making enough digestive enzymes, vitamins, nutrition support, or treatment for diabetes if it is present. You may be referred to a specialist, such as a gastroenterologist, dietitian, or diabetes team. Always follow the plan your healthcare professional gives you.

When is surgery considered?

Surgery or a procedure may be needed if gallstones are blocking a duct, if a duct is narrowed, if there are complications such as a cyst or infection, or for some long-term pancreas problems. Your specialist will explain the risks and benefits.

Living with this condition

Living with pancreas problems can mean paying attention to your body and keeping regular appointments. Keep track of pain, bowel habits, weight, and blood sugar if relevant. Ask your clinic who to contact between visits.

Lifestyle tips

• Limit or avoid alcohol
• Stay smoke-free
• Eat regular, balanced meals
• Take prescribed medicines as directed
• Keep active in a way that suits you
• Plan ahead for travel and clinic visits

Diet and exercise

A balanced diet with enough protein, vitamins, and healthy fats is important. Some people do better with smaller, more frequent meals. A dietitian can help you adjust your diet safely. Gentle activity, such as walking, can support your overall health. Ask your doctor what is right for you.

Mental health and emotional wellbeing

Ongoing symptoms, tests, and waiting for results can feel worrying. It is okay to ask for emotional support. If you feel overwhelmed or have thoughts of harming yourself, contact your local crisis service or emergency services right away.

Prevention

Not all pancreas problems can be prevented, but you can lower your risk. Limit alcohol, stay smoke-free, manage high triglyceride levels, treat gallstones if advised, and keep a healthy weight.

Vaccines

Stay up to date with routine vaccines. Ask your doctor if you need extra vaccines because of a long-term condition or treatment.

Screening programmes

There is no routine screening test for pancreas function for everyone. Tests are usually done when you have symptoms or risk factors. If you have a strong family history or an inherited condition, your doctor may advise a screening plan.

Complications

If left untreated

• Poor digestion and malnutrition
• Weight loss and vitamin deficiencies
• Diabetes if the pancreas stops making enough insulin
• Ongoing pain
• Infections or collections of fluid around the pancreas
• Long-term damage to the pancreas

Long-term outlook

Many pancreas problems can be managed with the right care. Early advice, follow-up, and support can make a real difference. Some people need long-term care, but your healthcare team can help you live as well as possible.
