Allergy is a disorder of the immune system often also referred to asatopy. Allergic reactions occur to normally harmless environmentalsubstances known as allergens; these reactions are acquired, predictable, and rapid. Strictly, allergy is one of four forms ofhypersensitivity and is called type I (or immediate) hypersensitivity. It is characterized by excessive activation of certain white blood cells called mast cellsand basophils by a type of antibody known as IgE, resulting in an extremeinflammatory response. Common allergic reactions include eczema, hives, hay fever, asthma attacks, food allergies, and reactions to the venom of stinging insectssuch as wasps and bees.[1]
Mild allergies like hay fever are highly prevalent in the human population and causesymptoms such as allergic conjunctivitis, itchiness, and runny nose. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threateninganaphylactic reactions and potentially death.
| Affected organ | Symptom |
|---|---|
| Nose | swelling of the nasal mucosa(allergic rhinitis) |
| Sinuses | allergic sinusitis |
| Eyes | redness and itching of theconjunctiva (allergic conjunctivitis) |
| Airways | Sneezing, coughing,bronchoconstriction, wheezingand dyspnea, sometimes outright attacks of asthma, in severe cases the airway constricts due to swelling known as laryngeal edema |
| Ears | feeling of fullness, possibly pain, and impaired hearing due to the lack of eustachian tubedrainage. |
| Skin | rashes, such as eczema andhives (urticaria) |
| Gastrointestinal tract | abdominal pain, bloating,vomiting, diarrhea |
Risk factors for allergy can be placed in two general categories, namely host andenvironmental factors.[10]. Host factors include heredity, sex, race, and age, with heredity being by far the most significant. However, there have been recent increases in the incidence of allergic disorders that cannot be explained by genetic factors alone. Four major environmental candidates are alterations in exposure toinfectious diseases during early childhood, environmental pollution, allergen levels, and dietary changes.
Homeopathy is a practice that involves giving you, the patient, minute doses of treatments that produce the same symptoms as the ones that you are trying to relieve. Doing so helps to stimulate your body’s own natural immune system to help fight off the allergy and resulting symptoms. A homeopathy treatment is a gradual process and is not designed to give you instant results. Your homeopathic practitioner needs to monitor your results progressively and may need to adjust your prescription as you go along. This process can take up to weeks or even a few months.
