Do you know anything about being lactose intolerant?
Well, I know that it is a condition that happens when people can't digest lactose very well
Yes -- all dairy products make you have gas or indigestion; however, there are things you can do about it.
Yeah, some symptoms from it can be gas, diarrhea, nausea and even pain in the abdomen
That sounds bad, does it couse any demage to the gastrointestinal tract?
Actually no, it doesn't cause any demage to this tract
Interesting. My father has primary lactose intolerance, what is this?
Well, this type of lactose intolerance happens when lactase declines with aging
Definitely the aging process has a lot to do with it. What else does it affect?

Response: Hmm, I heard inflammatory bowel disease makes it worse as you get older like lactose intolerant.
