Chronic pancreatitis is a long-term inflammation of the pancreas that often develops gradually and persists over time. It can result from repeated episodes of acute pancreatitis, prolonged alcohol consumption, smoking, genetic factors, or certain medical conditions. Symptoms typically include persistent abdominal pain, weight loss, diarrhea, and oily stools due to malabsorption of nutrients. Treatment focuses on managing symptoms, preventing complications, and addressing underlying causes, such as abstaining from alcohol, pain management, enzyme replacement therapy, and nutritional support. In severe cases, surgery may be necessary to relieve pain or improve drainage of blocked pancreatic ducts.
