Were you looking for information on Allergies? Alergies is a common misspelling of allergies.
Allergies are the immune system's specific reaction to a normally harmless substance, such as pollens, certain foods, or medicines. These reactions can be seasonal, occurring at specific times of the year, or perennial, occurring year-round. It is unknown why one person will develop allergies and another will not, although the tendency may be inherited. Being exposed to allergens at times when the body's defenses are lowered or weakened -- such as after a viral infection or during pregnancy -- also seems to contribute to their development.
Common symptoms include sneezing, coughing, runny nose, and itchy eyes, among others. In many cases, the problem can be treated with medication, reducing contact with specific allergens, or shots.
