Cockroach allergies can cause sneezing, wheezing, itchy eyes, cough and other symptoms common to allergic rhinitis. As in other common allergies, symptoms can range from mild to severe. But cockroach allergies may have especially dangerous health consequences to children. One study showed that kids who were allergic to cockroaches were hospitalized for asthma 3.3 times more often than other children—including children with allergies to dust mites or cats. Twenty-three percent to 60 percent of city dwellers with asthma are allergic to cockroaches. Some researchers believe that the rise in cases of asthma among urban children is due to increased contact with cockroach allergens, especially since kids play indoors more than they used to. Proteins in cockroach feces, saliva and bodies are thought to be the major culprit in triggering allergic responses.

An allergen such as mold spores or pollen enters the body through the mouth or nose or lands on the skin. Special white blood cells (T-cells) recognize the allergen as foreign and release chemicals in response. These chemicals travel through the blood and instruct another kind of white blood cell (B-cells) to produce IgE antibodies. Some of these antibodies attach to the outside of another special type of white blood cell called a mast cell. Mast cells are scattered throughout the skin and respiratory tract and their purpose is to help mediate the inflammatory response of the immune system. IgE antibodies can remain attached to mast cells for many years.
