How does chronic alcohol use increase risk of pancreatitis?

• A. Alcohol can cause pancreatic inflammation and changes in secretions; repeated injury leads to pancreatitis, with oxidative stress and ductal effects contributing.
• B. It has no effect on the pancreas.
• C. It reduces pancreatic enzyme production preventing pancreatitis.
• D. It only affects the liver.

Answer: (B)

Chronic alcohol use increases the risk of pancreatitis by directly hurting the pancreas and altering how it functions. Heavy drinking stimulates the pancreas to secrete more digestive fluids and can change the composition of that fluid, making it richer in proteins. Those protein-rich secretions can form plugs in the pancreatic ducts, causing ductal obstruction and higher pressure inside the gland. This environment promotes premature activation of digestive enzymes within the pancreas, leading to autodigestion and inflammation. Alcohol metabolism also generates oxidative stress and toxic metabolites that injure acinar cells, triggering inflammatory responses and cytokine release. Repeated cycles of injury and inflammation over time can cause scarring and fibrosis, characteristic of chronic pancreatitis. In short, alcohol’s effects on secretion, ductal flow, enzyme activation, and oxidative stress all contribute to increased pancreatitis risk, not a lack of effect.
