The small intestine produces the enzyme lactase which breaks hydrolyses the glycosidic bond
between glucose and galactose.
For people with LI , when the lactose reaches the small intestine, microorganisms break it down.
Why do microorganisms break it down? This is because the lactose has been undigested by the
lactase since people with LI produce little to no lactase from the lining of their small intestine.
The microorganisms then produce a lot of gas.
This may result in:
Bloating, nausea, diarrhoea and cramps.
