Chronic pancreatitis
Chronic pancreatitis - chronic; Pancreatitis - chronic - discharge; Pancreatic insufficiency - chronic; Acute pancreatitis - chronic
Pancreatitis is swelling of the pancreas. Chronic pancreatitis is present when this problem does not heal or improve, gets worse over time, and leads to permanent damage.
Causes
The pancreas is an organ located behind the stomach. It produces chemicals (called enzymes) needed to digest food. It also produces the hormones insulin and glucagon.
When scarring of the pancreas occurs, the organ is no longer able to make the right amount of these enzymes. As a result, your body may be unable to digest fat and key elements of food.
Damage to the parts of the pancreas that make insulin may lead to diabetes.
The condition is most often caused by alcohol abuse over many years. Repeated episodes of acute pancreatitis can lead to chronic pancreatitis. Genetics may be a factor in some cases. Sometimes, the cause is not known.
Alcohol abuse
Alcohol use involves drinking beer, wine, or hard liquor.
Other conditions that have been linked to chronic pancreatitis:
- Problems when the immune system attacks the body
- Blockage of the tubes (ducts) that drain enzymes from the pancreas
-
Cystic fibrosis

- High levels of a fat, called triglycerides, in the blood

Overactive parathyroid gland
Overactive parathyroid gland
Hyperparathyroidism is a disorder in which the parathyroid glands in your neck produce too much parathyroid hormone (PTH).
- Use of certain medicines (especially sulfonamides, thiazides, and azathioprine)
Chronic pancreatitis occurs more often in men than in women. The condition often develops in people ages 30 to 40.
Symptoms
Symptoms include:
ABDOMINAL PAIN
Abdominal pain is pain that you feel anywhere between your chest and groin. This is often referred to as the stomach region or belly.
- Greatest in the upper abdomen
- May last from hours to days; over time, may always be present.
- May get worse from eating or drinking
- May get worse from drinking alcohol
- May also be felt in the back
DIGESTIVE PROBLEMS
- Chronic weight loss, even when eating habits and amounts are normal
- Diarrhea, nausea, and vomiting
- Fatty or oily stools
-
Pale or clay-colored stools
Pale or clay-colored stools
Stools that are pale, clay, or putty-colored may be due to problems in the biliary system. The biliary system is the drainage system of the gallblad...
Exams and Tests
Tests to diagnose pancreatitis include:
-
Fecal fat test
Fecal fat test
The fecal fat test measures the amount of fat in the stool. This can help gauge the percentage of dietary fat that the body does not absorb....
-
Increased
serum amylase
level
Serum amylase
Amylase is an enzyme that helps digest carbohydrates. It is made in the pancreas and the glands that make saliva. When the pancreas is diseased or ...
-
Increased
serum lipase
level
Serum lipase
Lipase is a protein (enzyme) released by the pancreas into the small intestine. It helps the body absorb fat. This test is used to measure the amou...

Trypsinogen is a substance that is normally produced in the pancreas and released into the small intestine. Trypsinogen is converted to trypsin. Th...
Tests that may show the cause of pancreatitis include:
- Serum IgG4 (for diagnosing autoimmune pancreatitis)
- Gene testing, most often done when other common causes are not present or there is a family history
Imaging tests that can show swelling, scarring, or other changes of the pancreas may be seen on:
-
CT scan of the abdomen
CT scan of the abdomen
An abdominal CT scan is an imaging method. This test uses x-rays to create cross-sectional pictures of the belly area. CT stands for computed tomog...

Ultrasound of the abdomen

- Endoscopic ultrasound (EUS)
- Magnetic resonance cholangiopancreatography (MRCP)
ERCP is short for endoscopic retrograde cholangiopancreatography. It is a procedure that looks at the bile ducts. It is done through an endoscope.

Treatment
People with severe pain or who are losing weight may need to stay in the hospital for:
- Pain medicines
- Fluids given through a vein (IV)
- Stopping food or fluid by mouth to limit the activity of the pancreas, and then slowly starting an oral diet
-
Inserting a tube through the nose or mouth to remove the contents of the stomach (
nasogastric suctioning
) may sometimes be done. The tube may stay in for 1 to 2 days, or sometimes for 1 to 2 weeks.
Nasogastric suctioning
Gastric suction is a procedure to empty the contents of your stomach.
The right diet is important for people with chronic pancreatitis to keep a healthy weight and get the correct nutrients. A nutritionist can help you create a diet that includes:
- Drinking plenty of liquids
- Limiting fats
- Eating small, frequent meals (this helps reduce digestive symptoms)
- Getting enough vitamins and calcium in the diet, or as extra supplements
- Limiting caffeine
The health care provider may prescribe pancreatic enzymes. You must take these medicines with every meal. The enzymes will help you digest food better and gain weight.
Avoid smoking and drinking alcoholic beverages, even if your pancreatitis is mild.
Other treatments may involve:
- Pain medicines or a surgical nerve block to relieve pain
-
Taking insulin to control
blood sugar (glucose)
level
Blood sugar (glucose)
A blood glucose test measures the amount of a sugar called glucose in a sample of your blood. Glucose is a major source of energy for most cells of t...
Surgery may be recommended if a blockage is found. In severe cases, part or all of the pancreas may be removed.
Outlook (Prognosis)
This is a serious disease that may lead to disability and death. You can reduce the risk by avoiding alcohol.
Possible Complications
Complications may include:
-
Ascites
Ascites
Ascites is the build-up of fluid in the space between the lining of the abdomen and abdominal organs.
-
Blockage (obstruction) of the small intestine or
bile ducts
Bile ducts
Bile duct obstruction is a blockage in the tubes that carry bile from the liver to the gallbladder and small intestine.
- Blood clot in the vein of the spleen
-
Fluid collections in the pancreas (
pancreatic pseudocysts
) that may become infected
Pancreatic pseudocysts
A pancreatic pseudocyst is a fluid-filled sac in the abdomen. It may also contain tissue from the pancreas, enzymes, and blood.
- Diabetes
-
Poor absorption
of fat, nutrients, and vitamins (most often the fat-soluble vitamins, A, D, E, or K)
Poor absorption
Malabsorption involves problems with the body's ability to take in nutrients from food.
When to Contact a Medical Professional
Call your provider if:
- You develop symptoms of pancreatitis
- You have pancreatitis, and your symptoms get worse or do not improve with treatment
Prevention
Determining the cause of acute pancreatitis and treating it quickly may help prevent chronic pancreatitis. Limiting the amount of alcohol you drink can reduce your risk of getting this condition.
Acute pancreatitis
Acute pancreatitis is sudden swelling and inflammation of the pancreas.
