Lactose Intolerance

WHAT IS LACTOSE INTOLERANCE?
Lactose intolerance is when you can not digest the milk sugar, lactose. Lactose is found in foods and drink containing dairy products.

Some people are lactose-intolerant due to a deficiency of the enzyme “lactase” in their digestive tract. Normally, lactase breaks down the carbohydrate, lactose so it may be used by your body for energy, If lactose cannot be digested, it can cause cramping, gas, and diarrhea. People will differ in the severity of these symptoms based on the amount of lactase they can produce. The less lactase produced the greater degree of discomfort experienced.
