Acute pancreatitis is a sudden inflammation of the pancreas that can vary in severity from mild to life-threatening. It is typically caused by gallstones, excessive alcohol consumption, certain medications, infections, or high levels of triglycerides. Symptoms can include severe abdominal pain, nausea, vomiting, and fever. Treatment often involves hospitalization, pain management, IV fluids, and possibly antibiotics. Severe cases may require surgery or other interventions. Complications can include organ failure, infection, and potentially fatal pancreatic necrosis. Recurrent attacks of acute pancreatitis can lead to chronic pancreatitis, a long-term condition characterized by irreversible damage to the pancreas.
