A patient with a history of alcohol abuse presents with severe abdominal pain, nausea, vomiting, and elevated amylase and lipase levels. Which of the following is the most common initiating event in acute pancreatitis?

✓ Correct Answer: Option C

Acute pancreatitis is most commonly initiated by premature activation of trypsinogen to trypsin within pancreatic acinar cells. This leads to autodigestion of the pancreas by its own digestive enzymes, causing inflammation and damage.
