Why does steatorrhea (excess fat in feces) occur in individuals with cystic fibrosis, despite normal dietary fat intake?

💡 Explanation

Steatorrhea occurs due to impaired fat digestion because cystic fibrosis affects the exocrine glands, resulting in the production of thick mucus that blocks the pancreatic ducts, thus inhibiting pancreatic enzyme secretion; therefore, fat digestion is incomplete, rather than a result of increased water absorption, altered bile concentration, or microbiome changes.
