Thee Biological Basis of Lactose Intolerance

Lactase is produced by enterocytes lining the villi of the small intestine. Its primary function is to hydrolyze lactose into glucose and galactose, which are then absorbed through the intestinal wall. When lactase activity is deficient, unabsorbed lactose moves into the large intestine. There, resident bacteria—especially species of Bifidobacterium, Lactobacillus, and Clostridium—ferment the sugar, generating short-chain fatty acids, hydrogen, methane, and carbon dioxide. This fermentation process draws water into the colon, causing osmotic diarrhea, while the gases produce bloating, cramps, and flatulence. The severity of symptoms depends on the amount of lactose consumed, the residual lactase activity, and the composition of the gut microbiome.
