Allergy is defined as an excessive reaction of the body's natural defense system (immune system). Normally functioning immune system protects the body against viruses and bacteria by producing antibodies to fight them. In allergies, the immune system is also against normally harmless substances like dust mites, pollen or drugs and considers these substances were trying to attack the body. These reactions range from just a rash, itchy eyes, runny nose to difficulty breathing, nausea and diarrhea.
Allergic reactions usually occur during the first contact with an allergen (allergy causing substances). Example: the nut allergies, eating the first time will not cause allergic reactions because at that time just happened introduction of peanut allergens in the body. If you eat again for a second, then the body already knew him as an allergen and is producing antibodies that attack peanuts.
Some people have allergies and vary from mild to severe (may cause death). The majority of allergic reactions including mild-moderate category and home care can relieve some symptoms. Severe allergic reactions including anaphylactic reactions or are additional allergic reactions such as bleeding nose, ear problems, shortness of breath with wheezing and coughing.
Allergies often occur with other diseases such as asthma, ear infections, sinusitis and sleep apnea.
