My sister is really Lactose Intolerant. She couldnt have any dairy, without getting sick. She got sick to her stomach, stomach pains, and was constantly in the washroom.
So we stopped having dairy in the house (when she was still living here). The doctor didnt do any tests, because they said that it was so obvious that it was the dairy, so just to not have it and she would be fine.
Now, there is a new pill on the market, that my sister takes. Its really good if you can get it overseas. Its called Lactaid. It breaks down the lactose, and makes it so she can have a pizza slice or something without getting sick. Now she cant go overboard (she did, right after she saw that she could eat a pizza slice, and she went to eat the whole pizza the next time she got pizza!) You wouldnt believe how happy she is, to have this pill. She takes it before supper (or whenever she wants some dairy products) and waits 10 minutes, and then she can have the milk products.
I believe they can do scopes for Lactose as well. Where they put a camera down your espohogus, and see what damage you have done to your stomach and intestines. I know my mom had it done for both Lactose and Celiac. It is really uncomfortable, though. I wouldnt want to go through it as a child, or someone with a bad gag reflex. But the diagnosis is more accurate.
