  • Lactose intolerance

    Lactose intolerance is when the body does not make enough lactase, the enzyme needed to digest lactose the main sugar in milk. So lactose passes unchanged into the large intestine where it is fermented by bacteria causing cramps, gas and diarrhea. Depending on the degree of the intolerance, milk and sometimes dairy need to be restricted in the diet.
