The use of dairy products has been promoted for years as a way to ensure strong bones and healthy teeth. Back when Morgan Miller was just a teen she was surprised when she began experiencing sensitivity to a variety of milk products. "I noticed when I was twelve or thirteen, I'd go to Dairy Queen or whatever and then I just start noticing that I would get a runny noise right away," says Morgan

After going through several tests, she was diagnosed with a condition called lactose intolerance. "Lactose intolerance is one of the enzymes that most of the people have in their intestine, which digest milk and milk type of products and in people," explains Gastroenterologist Asif Choudhury.

Along with sinus problems, many people with this condition will also suffer from symptoms such as abdominal bloating and diarrhea. That's because their stomach simply cannot digest the milk properly. "Over the counter we have enzymes that helps digest those milk and milk products, so whenever they eat, they can have those enzymes taken by mouth," says Dr. Choudhury.

Morgan found her relief through a simple change in her diet. "I switched to soy milk, I also tried the soy ice cream and I liked it better actually, so I haven't had that much dairy since."

While many people may begin to develop symptoms of lactose intolerance in their later years, children as young as ten years old are linked to have a sensitivity to dairy products. Using lactose free milk is another way you can avoid the symptoms caused by this condition and can be found in most grocery stores near you.
