Frequently Asked Questions
An allergy occurs when the body's immune system reacts excessively to a normally harmless substance, known as an allergen. This exaggerated response prompts the immune system to produce antibodies, resulting in a wide range of symptoms that can vary from mild to severe.
The severity of an allergy can differ based on the allergen and the person. Sneezing, runny or stuffy nose, watery or itchy eyes, skin rash, hives, swelling (especially in the face, lips, tongue, or throat), coughing, wheezing, shortness of breath, abdominal pain, diarrhea, and nausea are typical clinical manifestations.
Allergies are usually detected through a combination of medical history, physical examination, and allergy testing. Depending on the suspected allergens, allergy testing can include skin prick tests, blood tests (such as specific IgE testing), or oral food challenges.
Allergies may not always be preventable, but there are things that can be done to lessen symptoms and limit exposure to allergens. These consist of wearing protective clothing when going outside, avoiding known allergens, using bedding that is free of allergens, keeping indoor spaces clean and clear of mold and dust, and adhering to a customized treatment plan created under the supervision of a healthcare professional.
To minimize symptoms during allergy season, consider staying indoors on high pollen days, keeping windows closed, using air purifiers with HEPA filters, wearing sunglasses and hats outdoors to protect against pollen exposure, showering and changing clothes after being outside, and using nasal saline rinses to flush out allergens.
Yes, some individuals may be sensitive to food additives or preservatives, which can trigger allergic reactions or exacerbate existing allergies. Common additives that may cause reactions include sulfites, monosodium glutamate (MSG), artificial colors, and artificial sweeteners.
