Cystic fibrosis can affect food digestion and nutrient absorption. The underlying mutation of
the cystic fibrosis trans-membrane regulator gene depletes functional cystic fibrosis trans-
membrane regulator on the surface of epithelial cells lining the digestive tract and
associated organs, where Cl− secretion and subsequently secretion of water and other ions
are impaired. This alters pH and dehydrates secretions that precipitate and obstruct the
lumen, causing inflammation and the eventual degradation of the pancreas, liver …
