Editing Enterocyte (section)

==Clinical significance==
*[[Fructose malabsorption|Dietary fructose intolerance]] occurs when there is a deficiency in the amount of [[fructose carrier]].
*[[Lactose intolerance]] is the most common problem of carbohydrate digestion and occurs when the human body doesn't produce a sufficient amount of [[lactase]] enzyme to break down the sugar lactose found in dairy. As a result of this deficiency, undigested lactose is not absorbed and is instead passed on to the colon. There bacteria metabolize the lactose and in doing so release gas and metabolic products that enhance colonic motility. This causes gas and other uncomfortable symptoms.
*[[Cholera toxin]] may increase the secretion or decrease the intake of water and electrolytes, leading to possibly severe [[dehydration]] and [[electrolyte imbalance]].<ref>{{cite journal |url=http://icmr.nic.in/ijmr/2011/february/0204.pdf |title=Cholera toxin – A foe & a friend |author=Joaquín Sánchez, Jan Holmgren |journal=Indian Journal of Medical Research |volume=133 |page=158 | date=February 2011 }}</ref>
