Pancreatitis

Organ or systemPancreasOrgan
Detail level

Pancreatitis is inflammation of the pancreas. The acute form causes sudden severe upper-abdominal pain and usually needs hospital care; the chronic form is long-term and gradually damages the pancreas.

The most common causes are gallstones and excessive alcohol; other causes include some medicines and inherited disorders. The NHS states that recovery from acute pancreatitis usually takes 5 to 10 days, and that it can cause serious complications such as cysts and tissue death.

It is diagnosed with a blood lipase test and imaging (ultrasound or CT). Hospital treatment includes intravenous fluids, painkillers, antibiotics if there is infection, and surgery to treat complications when needed, with a low-fat diet and avoiding alcohol.
