The pancreas is a gland that sits behind the stomach. Larger than your gallbladder, but smaller than the liver, the pancreas plays a key role in the digestive system. Pancreatitis is inflammation of the pancreas that usually begins as a sudden attack and is often caused by gallstones or alcohol abuse. Symptoms of acute pancreatitis often start with a gradual or sudden severe pain in the center part of the upper abdomen going through to the back. Treatment for pancreatitis often focuses on the nutritional and metabolic needs of the patient and on relieving pain. Most people with chronic pancreatitis have a good prognosis if they follow their treatment regimen
This condition can occur suddenly, soon after the pancreas becomes damaged or irritated by its own enzymes. Although acute pancreatitis is not fully understood, its causes are usually gallstones or alcohol abuse. When gallstones pass through the bile duct, they may become stuck, causing normally produced pancreatic enzymes to build up in the pancreas and ultimately damage the pancreas.
In the case of alcohol, the pancreas may be sensitive to the effects of excessive alcohol. An attack may occur anywhere from a few hours to one to two days after drinking alcohol. The amount of alcohol that needs to be consumed to cause pancreatitis will vary from person to person; it usually occurs after a pattern of excessive abuse, such as from binge drinking or excessive daily alcohol use.
Other less common causes of this condition are:
- Excessive levels of fat particles in the blood (triglycerides).
- Infections such as mumps.
- Some medications.
- Certain surgical procedures.
- Idiopathic (unknown causes). Acute pancreatitis affects about 80,000 Americans every year.
This stage of pancreatitis begins as acute pancreatitis and becomes chronic when the pancreas becomes permanently injured or scarred from repeated attacks of pancreatitis. Rarely, chronic pancreatitis may develop after one severe attack of acute pancreatitis.
Chronic pancreatitis is usually due to years of excessive alcohol consumption, but may also develop from other causes of pancreatitis.
Differences Between Acute and Chronic Pancreatitis
Most cases of acute pancreatitis are mild and involve a short hospital stay to help heal the pancreas. Chronic pancreatitis is a much more persistent condition. It occurs more often in men than women. Both acute and chronic pancreatitis can be mild or severe and may have the same symptoms. Often the only way to distinguish between acute and chronic pancreatitis is to look for visible scar tissue in the pancreas as seen by an abdominal X-ray, ERCP (endoscopic retrograde cholangiopancreatography), MRCP (magnetic resonance cholangiopancreatography), endoscopic ultrasound, or through evidence of chronic damage to the pancreas that it cannot produce digestive enzymes (causing fatty diarrhea) or insulin (diabetes).
- A gradual or sudden severe pain in the center part of the upper abdomen going through to your back; this pain may get worse when you eat and builds to a persistent pain.
- Nausea and vomiting.
- Jaundice (a yellowing of the skin) due to blockage of the bile duct from the inflamed pancreas.
- Weight loss. Due to the toxic effect of alcohol on pancreatic tissue, scarring can occur very early; therefore the first attack of acute pancreatitis can often occur on a gland that is very scarred and may be considered an acute flare of chronic pancreatitis.
- Pseudocysts, which are accumulations of fluid and tissue debris, may also develop. In rare cases, recurrent or chronic pancreatitis may lead to the development of cancer of the pancreas, an unchecked growth of abnormal cells in the pancreas.
Your doctor will focus treatment on your nutritional and metabolic needs and on relieving your pain. Mild pain can be treated with analgesics.
If the cause of acute pancreatitis is gallstones, you may have to have your gallbladder removed to prevent further attacks.
If the bile duct is found to be enlarged, you may need an ERCP to drain it. An ERCP is a way your doctor can examine your pancreas, pancreatic duct, the bile ducts, and/or the sphincter of Oddi. It involves passage of a long, narrow tube with a light and a camera at the end called an endoscope, through your mouth into your esophagus, stomach, and to the beginning of the small intestine. There, the endoscope is used to put x-ray contrast dye into the bile and pancreas ducts to look for gallstones or other blockages. In severe cases, surgery will be required to drain the pancreatic duct or to remove part of the pancreas.
Your doctor will also likely give you dietary guidelines to follow in order to reduce the amount of fats you eat, since your body has trouble digesting these substances. You may also need to take pancreatic enzyme supplements, which are in the form of a tablet, every time you eat a meal. These supplements will help your body absorb food, and help you regain some of the lost weight.
A low-fat diet and the enzyme supplements may help control pain by reducing stimulation of the pancreas.
If you drink alcohol, you need to stop drinking.
If you have a pancreatic pseudocyst, it may need to be drained by an endoscopic, radiological or surgical procedure.
If the cause is gallstones and your gallbladder has not been removed, avoid fatty and greasy foods, such as butter and fried eggs.
Work with your gastroenterologist to develop a healthy eating plan.
Ultimately, you may need your gallbladder removed. Your doctor should help you decide whether this surgery is needed.
If the cause is alcohol, you should stop drinking altogether.
