Allergies are the result of the immune system’s response to foreign objects such as pet dander, pollen, certain foods, bee venom etc. In response to the allergen, the immune system produces antibodies, anticipating that the allergen is harmful in nature, even though that might not be the case always. The immune system can inflame the digestive system, skin, airways or sinuses when it comes in contact with allergens. The severity of allergies can vary from anaphylaxis to a minor irritation. In most cases, allergies cannot be fully cured. It, however, can be controlled with medication.
