Acute pancreatitis is a condition where the pancreas becomes inflamed (swollen) over a short period of time.
The pancreas is a small organ, located behind the stomach, that helps with digestion.
Most people with acute pancreatitis start to feel better within about a week and have no further problems. But some people with severe acute pancreatitis can go on to develop serious complications.
Acute pancreatitis is different to chronic pancreatitis, where the pancreas has become permanently damaged from inflammation over many years.
