Pancreatitis is an inflammation of the pancreas, a large gland behind the stomach and close to the duodenum. The duodenum is the upper part of your small intestine.
The pancreas secretes digestive enzymes into the small intestine through a tube called the pancreatic duct. These enzymes help digest fats, proteins, and carbohydrates in food. The pancreas also releases the hormones insulin and glucagon into the bloodstream. These hormones help the body use the glucose it takes from food for energy.
Usually, digestive enzymes don’t turn active until reaching the small intestine, where they begin digesting food. But if these enzymes become active inside the pancreas, they start “digesting” the pancreas itself.
Acute pancreatitis occurs suddenly and lasts for a short period of time, and usually resolves on it’s own. Chronic pancreatitis does not resolve itself and results in a slow destruction of the pancreas. Either form can cause serious complications. In severe cases, bleeding, tissue damage, and infection may occur.
Pseudocysts, accumulations of fluid and tissue debris, may also develop. And enzymes and toxins may enter the bloodstream, injuring the heart, lungs, and kidneys, or other organs.
Symptoms of Acute Pancreatitis
Acute pancreatitis typically starts with a pain in the upper abdomen that may last for a few days. The pain can be severe and may become constant, just in the abdomen, or it may reach to the back and other areas. It may be sudden and intense or begin as a mild pain that gets worse when food is eaten. Someone with acute pancreatitis often looks and feels very sick. Other symptoms may include
* swollen and tender abdomen
* rapid pulse
Severe cases may cause dehydration and low blood pressure. The heart, lungs, or kidneys may fail. If bleeding occurs in the pancreas, shock and sometimes even death follow.
Treatment will depend on the severity of the attack. If no kidney or lung complications occur, acute pancreatitis usually improves on its own. Treatment, in general, is designed to support vital bodily functions and prevent complications. A hospital stay will be necessary so that fluids can be replaced intravenously.
If pancreatic pseudocysts occur and are considered large enough to interfere with the pancreas’s healing, your doctor may drain or surgically remove them.
Unless the pancreatic duct or bile duct is blocked by gallstones, an acute attack usually lasts only a few days. In severe cases, a person may require intravenous feeding for 3 to 6 weeks while the pancreas slowly heals. This process is called total parenteral nutrition. However, for mild cases of the disease, total parenteral nutrition offers no benefit.
Before leaving the hospital, a person will be advised not to drink alcohol and not to eat large meals. After all signs of acute pancreatitis are gone, the doctor will try to decide what caused it in order to prevent future attacks. In some people, the cause of the attack is clear, but in others, more tests are needed.
