What Causes Acute Pancreatitis? The Top Culprits Revealed
Published: Jan 29, 2024
Acute pancreatitis is a painful inflammation of the pancreas that can land you in the hospital. But what triggers this sudden attack on your digestive system?
Contents
The Gallstone Culprit
Gallstones are the most common cause of acute pancreatitis, responsible for 40-70% of cases. These small, hardened deposits in your gallbladder can block the pancreatic duct, causing inflammation. It's like a traffic jam in your digestive system, with painful consequences. Interestingly, only 3-7% of people with gallstones develop pancreatitis, so having stones doesn't guarantee you'll have an attack.
The Alcohol Connection
Alcohol is the second most common cause, accounting for 25-35% of acute pancreatitis cases. Long-term heavy drinking can overstimulate the pancreas, leading to inflammation. Think of it as overworking your pancreas until it rebels. However, not everyone who drinks heavily will develop pancreatitis, suggesting other factors may be at play.

Other Surprising Triggers
While gallstones and alcohol are the main culprits, other factors can cause acute pancreatitis. High triglyceride levels (>1000 mg/dL), certain medications, and even some infections can inflame your pancreas. In rare cases, genetic factors or anatomical abnormalities might be to blame. It's like a pancreatic perfect storm when these conditions align.
