What is the most common cause of chronic pancreatitis?

• A. Alcohol abuse
• B. Autoimmune disease
• C. Obstructive biliary disease
• D. Idiopathic

Answer: (A)

Chronic pancreatitis most often results from long-term, heavy alcohol use. Repeated alcohol-related injury drives ongoing inflammation and fibrosis of the pancreatic tissue, eventually leading to a small, fibrotic gland with ductal changes and sometimes calcifications. This pattern makes alcohol abuse the leading identifiable cause in most populations. Other etiologies exist—autoimmune pancreatitis can cause chronic changes, and obstructive problems (like ductal obstruction) can contribute—but they are less common than alcohol as a cause. Historically, many cases were labeled idiopathic when no cause was found, but when a clear etiologic factor is present, alcohol remains the most frequent one in adults.
