Pancreatitis is inflammation of your pancreas. Your pancreas sits behind your stomach, near your small intestine. It releases enzymes that help you digest food and also regulates how your body manages glucose.

Pancreatitis can come and go quickly, or it can be a chronic problem. Treatment will depend on whether your pancreatitis is acute or chronic.

Pancreatitis is generally acute or chronic. Necrotizing pancreatitis can result from extreme cases of acute pancreatitis. Treatment for each case of pancreatitis depends on the severity of symptoms.

Acute pancreatitis

Acute pancreatitis is a main cause of hospital admissions for gastrointestinal issues.

According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), around 275,000 people are admitted to the hospital for acute pancreatitis every year in the United States.

The onset of acute pancreatitis is often very sudden. The inflammation usually clears up within several days after treatment begins, but some cases could require a hospital stay.

Acute pancreatitis is much more common in adults than in children. Gallstones are the primary cause of acute pancreatitis in adults.

The condition can also develop into chronic pancreatitis, especially if you smoke or drink alcohol heavily. Learn more about acute pancreatitis.

Chronic pancreatitis

Chronic pancreatitis is an inflammation of the pancreas that comes back consistently or occurs over a long period of time.

People with chronic pancreatitis can have permanent damage to their pancreas and other complications. Scar tissue develops from this continuing inflammation.

Pancreatitis can damage cells that produce insulin. Insulin is a hormone the pancreas releases to regulate the amount of sugar in your blood. When pancreatitis damages these cells, it leads to diabetes in about 45 percent of people with chronic pancreatitis.

Long-term heavy alcohol use can cause pancreatitis in adults. Autoimmune and genetic diseases, such as cystic fibrosis, can also cause chronic pancreatitis in some people. Find out how to manage chronic pancreatitis.

Necrotizing pancreatitis

Severe cases of acute pancreatitis can develop into necrotizing pancreatitis, which refers to the death of cells due to disease. This occurs in about 10 percent of acute pancreatitis cases, typically when pancreatitis is left untreated.

Inflammation from pancreatitis can cause digestive enzymes to leak into the pancreas. This can result in damage and death of the tissue, leading to necrotizing pancreatitis. Your doctor may order an abdominal ultrasound or CT scan to diagnose the condition.

If you have necrotizing pancreatitis, your doctor may take a sample of the dead tissue to make sure it hasn’t become infected. If you have an infection, you’ll likely need to take antibiotics. You may need to have the dead tissue removed.

The infection of dead tissue increases the risk of death from necrotizing pancreatitis, so it’s very important to seek treatment as quickly as possible. Learn more about diagnosing and treating necrotizing pancreatitis.

Most people who have acute or chronic pancreatitis usually experience middle-left upper abdominal pain as their primary symptom.

Some people who have chronic pancreatitis may show inflammation on diagnostic imaging scans, but they may show no symptoms otherwise.

Acute pancreatitis symptoms

  • pain that starts slowly or suddenly in the upper abdomen
  • pain that may spread to the back
  • mild or severe pain
  • pain that may last for several days
  • fever
  • nausea
  • vomiting
  • swollen or tender abdomen
  • fast heart rate

Chronic pancreatitis symptoms

  • pain in the upper abdomen or no pain at all
  • pain that may spread to the back
  • pain that may become worse after eating
  • diarrhea
  • nausea
  • weight loss
  • vomiting

People who have chronic pancreatitis may also experience steatorrhea, which is fatty stools that give off a foul odor.

Steatorrhea can be a sign of malabsorption. This means you’re not getting all of your essential nutrients because your pancreas doesn’t secrete enough digestive enzymes to break down your food.

Acute and chronic pancreatitis share many of the same causes. These include:

High levels of calcium or triglycerides (a type of fat) in the blood can also lead to chronic pancreatitis.

Gallstones are the most common cause of acute pancreatitis. Gallstones are small, solid masses that form from bile, a fluid that helps with digestion.

A large enough gallstone can get stuck at the junction where the main pancreatic duct and the common bile duct come together. These ducts empty into the duodenum, the first part of the small intestine.

The pancreatic duct carries digestive enzymes from the pancreas. The common bile duct carries bile or other substances from the liver and the gallbladder.

A stuck gallstone can cause a backup of these substances, leading to inflammation in both the common bile duct and the pancreas.

Several factors increase your risk of developing pancreatitis. These include:

A combination of risk factors, like smoking and having a family history of pancreatitis, increases your chances of getting pancreatitis.

Smoking or drinking alcohol may also increase the risk of acute pancreatitis developing into chronic pancreatitis.

Some people may develop complications from pancreatitis. These complications are rare, but they’re more common in people with chronic pancreatitis:

It can cause pseudocysts to form when tissue and other debris collect on your pancreas. These may go away by themselves. If they rupture, it can cause infection and bleeding that can be fatal if untreated.

Your doctor will likely use a combination of blood tests and imaging studies to make a diagnosis. If you have acute pancreatitis, you’ll have severe abdominal pain. Blood tests may show a significant rise in your level of pancreatic enzymes.

Different types of ultrasound, MRI, and CT scans can reveal the anatomy of your pancreas, signs of inflammation, and information about the biliary and pancreatic ducts.

A fecal fat test can also determine whether your stools have fat content that’s higher than normal.

Treatment for acute or chronic pancreatitis often involves hospitalization. The pancreas is a key contributor to your digestive processes and needs to rest to heal.

For this reason, you may receive specifically tailored fluids and nutrition intravenously (IV) or through a tube that goes from your nose directly into your stomach. This is called a nasogastric feeding tube.

Medication may help manage the pain. You may also receive artificial digestive enzymes for chronic pancreatitis if your pancreas isn’t producing enough of them on its own.

Restarting an oral diet depends on your condition. Some people feel better after a couple of days. Other people need a week or two to heal sufficiently.

Surgery

You may need surgery if other treatments aren’t working. If your doctor diagnoses gallstones, surgery to remove the gallbladder may help. Surgery can also remove diseased parts of your pancreas.

Pancreatic function test

The pancreatic function test, also called the secretin stimulation test, shows whether your pancreas is responding normally to secretin. Secretin is a hormone that causes your pancreas to release a fluid that helps digest food.

During the test, your doctor will run a tube through your nose or throat and down into your small intestine. They’ll inject secretin into your vein, then take samples of fluid through the tube.

Your doctor will send the fluid to a lab to help diagnose pancreatitis or other conditions affecting your pancreas. Learn what to do to prepare for a pancreatic function test.

A low fat, balanced diet plays a major role in recovering from pancreatitis.

People with chronic pancreatitis in particular need to monitor the amount of fat they consume, since their pancreas function has become compromised. Try to limit or avoid the following foods:

  • red meat
  • fried foods
  • full fat dairy
  • sugary desserts
  • sweetened beverages
  • caffeine
  • alcohol

Eat small meals throughout the day to put less stress on your digestive system. Stick to foods that are high in protein and antioxidants. Drink lots of fluids to stay hydrated.

Your doctor might also give you vitamin supplements to ensure that you’re getting the nutrients you need. Learn more about following a diet to help you recover from pancreatitis.

It’s important to see your doctor if you think you have pancreatitis, especially if you have consistent pain in your abdomen. There are steps you can take at home to supplement your treatment and help prevent pancreatitis.

Lifestyle changes

If you smoke or drink, quit smoking tobacco and curb drinking alcohol to help you heal more quickly and completely. Your doctor can provide guidance if you need support.

Maintaining a moderate weight can help you avoid gallstones, a primary cause of pancreatitis. Eating a balanced diet and staying hydrated can also help you recover from and prevent pancreatitis.

Alternative techniques for pain control

You’ll probably be given IV pain medication in the hospital. Alternative therapies may also help reduce pancreatitis pain.

If conventional treatments don’t reduce your pain, you can try:

These alternative treatments focus on slow, measured movements that may take your mind off your discomfort.

A small 2017 study found that acupuncture may provide short-term pain relief for people with chronic pancreatitis.

Pain associated with pancreatitis may last from a few minutes to several hours at a time. In severe cases, discomfort from chronic pancreatitis could become constant.

Your pain is likely to increase after you eat or when you’re lying down. Try sitting up or leaning forward to make yourself more comfortable.

Depending on the cause, you may not be able to prevent pancreatitis. Still, there are several things you can do to reduce your risk:

  • limit alcohol use
  • stop smoking
  • maintain a moderate weight
  • eat a balanced diet

Eating high fiber foods and avoiding sugar may help you prevent gallstones, which are the main cause of acute pancreatitis.

You can manage pancreatitis with a healthy, balanced lifestyle and medical treatment when necessary. It’s particularly important to avoid smoking and drinking a lot of alcohol to reduce your risk of pancreatitis and to help you recover.

If any of your symptoms reappear, speak with your doctor as soon as possible.
