Suggest how the exhaled air of a lactose-intolerant person could have raised levels of hydrogen gas after ingesting 50 g of lactose in a drink.

I actually did the test at a hospital. It was explained something about during the digestion process, a lack of enzymes to break down the lactose in the digestive system meant that they "fermented" instead due to bacteria and therefore hydrogen was released. Something along those lines but I am not a biologist or doctor or anything so double check!
