Skin Reactions

For instance, a food allergy often triggers these kinds of stomach troubles, making you feel quite unwell. It can be a very immediate response, in some respects.

Different Kinds of Allergies

Allergies come in many forms, each with its own set of common triggers and typical reactions. Knowing the type of allergy you're dealing with can help you manage it better. There are, honestly, quite a few kinds out there.

Food Allergy

A food allergy is when your immune system reacts to a specific food soon after you eat it.
