About Pancreatic Insufficiency

Overview

Pancreatic insufficiency (PI), also known as exocrine pancreatic insufficiency, is a condition where the pancreas does not make enough enzymes to properly digest food in the small intestine. This can happen due to damage from conditions like chronic pancreatitis (long-term inflammation of the pancreas), diabetes, autoimmune diseases, or pancreatic or gastrointestinal cancer. In children, it is often linked with cystic fibrosis or rare genetic diseases. The lack of enzymes causes problems like poor absorption of nutrients, malnutrition (not getting enough nutrients), lack of vitamins (avitaminosis), and weight loss or failure to gain weight in children. PI can lead to problems such as low bone mass (weaker bones), growth problems in children, and a reduced ability to feel well day-to-day if not treated. Treatment focuses on addressing the cause, preventing further damage to the pancreas, and relieving symptoms. It is important to talk with a healthcare professional for the right diagnosis and care.

Causes and Risk Factors

The root causes of pancreatic insufficiency can include:

• Chronic pancreatitis: Repeat or long-term inflammation of the pancreas can damage the cells that make digestive enzymes, causing problems with digestion.
• Cystic fibrosis: This genetic disorder affects many organs, including the pancreas, reducing its ability to make enzymes needed for digestion.
• Pancreatic cancer: Tumors in the pancreas can block the ducts, or damage enzyme making cells, leading to insufficient enzyme production. A cancerous growth in or near the pancreas can also impair its ability to function properly, adding to insufficiency.
• Complications from gastrointestinal (GI) surgery: Surgeries that affect the pancreas or nearby organs can damage the pancreas or disrupt its ability to release enzymes.

Non-modifiable risk factors for pancreatic insufficiency cannot be changed or controlled. These include:

• Age: The risk increases with age, as the pancreas may not work as well.
• Genetic disorders: Conditions like cystic fibrosis and hereditary pancreatitis (inherited from the family) raises the risk of problems making enzymes.

Modifiable risk factors for pancreatic insufficiency are not well understood. However, keeping a healthy lifestyle and avoiding things that lead to chronic pancreatitis, like drinking too much alcohol and smoking, may help lower the risk.

Symptoms

The early symptoms of pancreatic insufficiency (PI) may include:

• Nausea and vomiting
• Frequent, loose, and watery stools
• A feeling of fullness or swelling in the stomach (bloating)
• Stools that are greasy, float in the toilet, and may be hard to flush due to undigested fat
• Pale-colored stool: Stools that are lighter in color than normal due to the lack of bile and undigested fat
• Pain in the upper abdomen, especially after eating: Discomfort or pain in the upper part of your stomach, often worse after eating.

As PI progresses or becomes gets worse, additional symptoms may occur, such as:

• Unexplained weight loss: Losing weight without trying, due to the body not taking in nutrients properly
• Fatigue: Feeling extremely tired or weak, often due to not getting enough nutrients, vitamins, or minerals the body needs
• Anemia: A condition where you don’t have enough red blood cells, often due to low levels ofiron or vitamin B12
• Osteopenia and osteoporosis: These are conditions where bones become weak and brittle. This can happen because the body isn’t able to take in enough calcium and vitamin D, which are important for strong bones.
• Blood clotting problems: Trouble with blood clotting, which can happen when there is a lack of vitamin K, which helps with blood clotting.

It's important to note that the symptoms of PI can be similar to those of other conditions. If you notice any changes in your digestion, it’s a good idea to talk with a doctor. If you have concerns about PI or its symptoms, it's best to seek medical advice for an accurate diagnosis and proper treatment.

Diagnosis

To diagnose pancreatic Insufficiency, the following exams, tests, and procedures are commonly performed:

• History and physical exam: A healthcare provider will ask about your symptoms and any factors that may be causing your condition. They will look for physical signs such as weight loss, bloating or swelling, signs of malnutrition, and ask about any changes in stool.
• Lab tests: These may be recommended to check for problems related to how the pancreas is working. These tests can include:
  • Pancreatic function tests: To check how well the pancreas is working
  • Evaluation of mild digestive problems: Looking into symptoms like diarrhea or gas
  • Nutritional status: Checking if the body is getting enough nutrients.
  • Fecal elastase-1 test: This test checks enzyme levels in the stool to see if the pancreas is making enough digestive enzymes.
  • Secretin stimulation test: This test measures the ability of the pancreas to release digestive enzymes in response to secretin, a hormone.
  • Measurement of fecal chymotrypsin activity: This test measures the levels of the enzyme chymotrypsin in the blood, showing how well the pancreas is working.
• Imaging studies: Imaging studies like X-rays or magnetic resonance imaging (MRIs) may be suggested to give a clear picture of the pancreas. These can help identify any problems or damage to the pancreas.

To determine the stage or severity of pancreatic insufficiency, additional examinations, tests, and procedures may include:

• 13C dipeptide breath test: In this breath test, a specific meal or substance is given that contains carbon molecules labeled with 13C. These molecules need pancreatic enzymes to be broken down. Once digested, the labeled carbon is exhaled in the breath. Measuring the amount of labeled carbon in the breath helps check pancreatic enzyme activity and function.
• Cine-dynamic magnetic resonance cholangiopancreatography (MRCP): This is a specialized form of MRCP that provides real-time, moving images of the pancreatic ducts to see how they function as the pancreas releases fluids. It helps check the seriousness and detect blockages or other unusual changes in the ducts.
• Nutritional index markers assessment: This involves measuring different nutritional markers like vitamin levels and body mass index (BMI) to check the effects of PI on nutrition and health.

Remember to talk with your healthcare provider about which specific exams, tests, and procedures are right for your individual situation.

Treatment Options

The goals of treatment for pancreatic are to help the body take in nutrients better and prevent the lack of important nutrients.

The main treatment option for pancreatic insufficiency is:

• Pancreatic enzyme replacement therapy (PERT): This involves taking enzyme supplements by mouth to replace the digestive enzymes that the pancreas isn’t making. These enzymes help break down fats, proteins, and carbohydrates so the body can take them in properly.

Other treatments that may be recommended include:

• Health behavior changes: Making dietary changes such as eating less fat and having smaller, more frequent meals can help improve digestion and the way your body takes in nutrients. Avoiding alcohol and stopping smoking can also help.
• Medications to reduce stomach acid: In cases where PERT alone is not enough, medications that lower stomach acid might be used. These medications help make the enzyme supplements work better by reducing stomach acid. These medications include:
  • H2-receptor blockers: They reduce the amount of acid made by the stomach.
  • Proton pump inhibitor (PPIs): Medications that block the production of acid in the stomach.
• Therapeutic procedures: In some cases, therapeutic procedures like total mesopancreatic excision (removal of part of the pancreas and nearby tissue) or radiotherapy (using high-energy rays to target and destroy cancer cells) may be considered to improve outcomes for specific conditions linked with pancreatic insufficiency, such as pancreatic cancer.

It is important to note that specific treatment recommendations may vary based on individual circumstances. It is always recommended to talk with a healthcare professional for personalized advice and guidance.

Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
