How Do You Know If Lactose Intolerant?

[jennrus 176]

For a while i had major runs so stopped Protein Shakes with milk. For a week. Today had one and been running to bathroom all day. Yet yogurt doesnt bother me.

My daughter is lactose intolerant. She gets really ill if she drinks milk, however yogurts and cheeses are easily digested.

It may be common?
