Level of triglycerides that causes pancreatitis?

• A. 500 mg/dL
• B. 1000 mg/dL
• C. 800 mg/dL
• D. 1200 mg/dL

Answer: (B)

Extremely high triglycerides can trigger pancreatitis because the excess TGs are carried in large chylomicrons that thicken the blood and can clog pancreatic capillaries. This slows blood flow to the pancreas and, as pancreatic lipase acts on these triglycerides, free fatty acids are released in a concentrated area, injuring acinar cells and surrounding tissue. These combined effects provoke inflammation and pancreatitis. The level around 1000 mg/dL is the classic threshold where this risk becomes significant, which is why that value is chosen as the correct answer. Levels somewhat lower are less likely to cause pancreatitis on their own, while higher levels still carry risk, but 1000 mg/dL is the established tipping point in many references.
