That is, an allergy sufferers' immune system will not only protect them from viral enemies, but also from many of the common allergens faced daily such as pollen, spores, mold, and certain foods. According to Russell Roby LL.B.,M.D., it is often passed from parent to child, generation to generation. There are many symptoms to indicate allergies and many treatments available. An allergy sufferer should prepare and control his environment and avoid exposure to offending agents. While there wouldn't be an entire absence of dust, there wouldn't be an accumulation of it either, thereby decreasing the allergy sufferers' exposure to that offending agent.
Medication is an important form of therapy and is essential to the asthmatic.
However, in most situations it only alleviates the symptoms of the sufferer without identifying the cause of the problem. The relief brought on by medication can be adequate to the patient and therefore no other treatment is necessary. Small amounts of allergens are injected into the allergy sufferer periodically to induce blocking antibodies. Again this is not a cure for allergies but rather an attempt to build up tolerance to the offending allergens or antigens. Reactions to immunotherapy are possible though not common.
