Pancreatitis is an inflammation of the pancreas, a gland that helps with digestion and regulates blood sugar. It can occur suddenly, known as acute pancreatitis, or develop over time, referred to as chronic pancreatitis. Common causes include excessive alcohol consumption, gallstones, and certain medications. Symptoms of pancreatitis may include severe abdominal pain, nausea, vomiting, and fever. Diagnosis typically involves blood tests, imaging studies like CT scans, and sometimes endoscopic procedures. Treatment often requires hospitalization, where patients may receive fluids, pain relief, and dietary changes to help the pancreas heal.
