Pancreatitis is an inflammation of the pancreas, a gland located behind the stomach that helps with digestion and blood sugar regulation. This condition can be acute, meaning it comes on suddenly and lasts for a short time, or chronic, where it persists over a long period. Common causes include excessive alcohol consumption, gallstones, and certain medications. Symptoms of pancreatitis often include severe abdominal pain, nausea, vomiting, and fever. If left untreated, it can lead to serious complications, such as infection or damage to other organs. Treatment typically involves hospitalization, where doctors may provide fluids, pain relief, and dietary changes to help the pancreas heal.
