K85: Acute pancreatitis

Acute pancreatitis is a sudden inflammation of the pancreas, an organ that lies behind the lower part of the stomach. This condition mainly occurs when digestive enzymes become activated while still in the pancreas, attacking and damaging the organ's tissues. A few common causes include gallstones and heavy alcohol use. In its early stages, acute pancreatitis can trigger upper abdominal pain that often radiates to the back. Other symptoms may include fever, nausea, vomiting, and a rapid pulse. Progressing further, acute pancreatitis might lead to serious complications, such as pancreatic necrosis, infection, and occasionally, organ failure. This can sometimes be life-threatening. However, with the appropriate medical care, less severe cases of acute pancreatitis are usually resolved.
