It is more common in Asians for some reason. My husband is filipino and is starting to have symptoms...his sisters too. I did read that you can develop Lactoce Intolerance as an adult not a child because children aren't old enough to have built up a intolerance to it yet. Happens in adulthood since we've used up all our digestive enzymes. I also read that cheeses are more easily tolerated because of how they're processed. I might also have a bit sensitivity because the past week I was eating cold cereal every other day and each time, the next day I would have a loose stool. Maybe I'll just have cereal w/ lactaid. Good Luck to you ...hope it's only lactose intolerance.
