Chronic pancreatitis is a long-lasting inflammation of the pancreas, an organ that helps with digestion and blood sugar regulation. This condition can lead to permanent damage, affecting the pancreas's ability to produce digestive enzymes and hormones. Common causes include excessive alcohol consumption, certain genetic disorders, and autoimmune diseases. Symptoms of chronic pancreatitis may include abdominal pain, weight loss, and digestive issues such as diarrhea or oily stools. Diagnosis typically involves imaging tests like CT scans or MRI, and treatment focuses on managing pain, improving digestion, and addressing any underlying causes to prevent further damage.
