Allergic reactions can be mild, like sneezing or coughing. They can also be severe, such as anaphylaxis. Anaphylaxis is characterized by difficulty breathing or swallowing, swelling of the lips, tongue, or other parts of the body, dizziness or loss of consciousness. This usually occurs within minutes after contact with the allergen but can take up to 4 hours. These kind of allergic reactions are rare and can be treated successfully if treated correctly.
If the allergen is breathed in, such as flower pollen the reaction usually occurs in the nose, and eyes. If the allergen is eaten, such as peanuts, then the reaction is usually in the mouth, tongue, throat and/or the intestinal tract. If the allergen touches the skin, such as poison ivy, the allergic reaction is usually swelling or itching.
Histamines, along with other similar chemicals, are known as mediators and are generally responsible for many of those physiological reactions we associate with an allergic reaction such as itching and itchy eyes, rashes, hives, sneezing, nausea, and a runny nose. They can also induce much more serious reactions including difficulty breathing (constriction of the airway), a dilation of blood vessels, and of course, anaphylactic shock.
