Larger than your gallbladder, but smaller than the liver, the pancreas plays a key role in the digestive system. Its juices join bile from the liver and gallbladder to drain into the small intestine. The digestive substances split the fats, proteins, and carbohydrates into digestible molecules.
Pancreatitis is inflammation of the pancreas.
When the pancreas becomes inflamed, the digestive enzymes attack the tissue that produces them. One of these enzymes, called trypsin, can cause tissue damage and bleeding, and can cause the pancreas blood cells and blood vessels to swell. With chronic pancreatitis, the pancreas may eventually stop producing the enzymes that are necessary for your body to digest and absorb nutrients. This is called exocrine failure and fat and protein are not digested or absorbed. Although acute pancreatitis is not fully understood, its causes are usually gallstones or alcohol abuse.
