People with lactose intolerance do not produce enough of the lactase enzyme to break down lactose. Instead, undigested lactose sits in the gut and gets broken down by bacteria, causing gas, bloating, stomach cramps, and diarrhea.

Dairy. The fermentation of dairy products in our intestines can also lead to gas symptoms. Lactose intolerance is an inability to digest lactose â the sugar found in dairy foods. This is caused by a deficiency of the natural enzyme called lactase (say LACK-tays), which breaks down the milk sugar to make it digestible. Left undigested, the milk sugar lactose (say LACK-toes) can lead to the production of gas, bloating, diarrhea, and stomach discomfort. The product LactaidÂ® can relieve this gas if taken with the first mouthful or sip of dairy products.
