Could this be lactose intolerance?

If it's not lactose intolerance, then what could it be?

• So I thought that I've developed lactose intolerance because whenever I eat stuff like macaroni and cheese or anything else with dairy in it, I end up feeling really sick (bloated, gassy, nauseous, and difficulty breathing because of gas pressure). The symptoms usually last 2 to 3 hours before they start going away. I take gas relief pills containing simethicone but they don't seem to help at all. The reason why I'm thinking that this might not be lactose intolerance is because I get the symptoms immediately after I eat the food or while I'm eating. I read that lactose intolerance symptoms don't start until 30mins after you eat.

  Sounds like it to me, and I have been very intolerant in the past. You need to get lactaid, or it's equal in generic form. Take 1 with the first bite of milk product and it helps tremendously. I have found that drinking alcohol and periods of stress make it much worse. Yogurt with live cultures helps. You might try the probiotics, that helps too.
