Sometimes allergies are delayed reaction and some can be immediate. It's a good idea to see a doctor to see what you are allergic to and to formulate a game plan. I agree with SassyLassie above, too!

Hello~My food allergies usually cause Anxiety attacks. I use to have many food allergies, but now, I hardly have any and the ones I do have really don't cause many symptoms at all. Oh, I do know that food allergies can cause weight gain in certain people, especially if it is wheat. Allergies are hard to detect at times and can be hard to control.
