Pancreatitis is a condition in which the digestive enzymes of the pancreas are activated within the gland, leading to tissue destruction and scarring of the pancreas. The disease can be acute and resolve within days, or chronic and cause irreversible damage and even be life-threatening. The causes include gallstones, excessive alcohol consumption, high triglyceride levels, and medications. Symptoms include severe abdominal pain radiating to the back, nausea, vomiting, and elevated pancreatic enzymes in the blood. Acute treatment requires fasting, fluids, and pain management; in chronic cases, dietary modification, enzyme therapy, and sometimes surgery are required.
