Question

Common cause of chronic pancreatitis:

• A. Chronic alcohol
• B. Chronic pancreatic calculi
• C. Pancreas divisum
• D. Gall bladder stones

Hint:

Gallstones cause acute pancreatitis; the leading cause of chronic pancreatitis is something you drink.

Answer 1

The Correct Option is A

Step 1: Separate the two questions students confuse: what causes acute pancreatitis versus chronic pancreatitis. Gallstones top the acute list; alcohol tops the chronic list.
Step 2: For chronic pancreatitis the dominant driver in adults is long-standing alcohol intake, responsible for roughly $70\%$ of cases. The mechanism is repeated acinar injury, protein plugs, ductal calcification and steady fibrosis.
Step 3: Eliminate the distractors. Pancreatic calculi appear because of the disease, so they are an effect, not the usual cause. Pancreas divisum is a rare congenital variant and only sometimes contributes.
Step 4: Gallbladder stones are the hallmark of acute, not chronic, disease. So the best single answer for the common cause of chronic pancreatitis is chronic alcohol.
