When your pancreas doesn't make enough digestive enzymes, your body can't break down fats properly, so you can't absorb important vitamins like A, D, E, and K from your food — leading to deficiencies.

Appropriate Language Strength

Can make definitive causal claims
Assessment Explanation
The biological mechanism is well-established: pancreatic enzymes (lipase, colipase) are essential for fat emulsification and absorption; without them, fat-soluble vitamins cannot be incorporated into micelles and absorbed in the small intestine. Multiple clinical and physiological studies confirm this pathway in humans with conditions like chronic pancreatitis or cystic fibrosis. The claim uses precise causal language consistent with known physiology.
More Accurate Statement
“Exocrine pancreatic insufficiency causes deficiency of fat-soluble vitamins (A, D, E, K) by impairing the digestion and intestinal absorption of dietary fats, which are required for their solubilization and uptake.”

When the pancreas doesn’t work right, it can’t help digest fats, and since vitamins A, D, and E need fat to be absorbed, people with this problem often end up lacking those vitamins — and this study found exactly that.
