The Oxford Dictionary defines allergy as a damaging immune response to a substance. The American Academy of Allergy, Asthma & Immunology (AAAAI), a professional organization with over 7,000 members in the United States, Canada, along with 72 other countries explains that an allergic reaction occurs when the immune system overreacts to a harmless substance known as an allergen or antigen. According to Clinical Professor of Internal Medicine and Immunology Clinical Professor of Pediatrics Mary Beth Fasano, MD, MSPH, and member of the AAAAI, not everyone exposed to a substance will develop a sensitivity or allergy to the allergen or antigen they are exposed to. When a reaction does occur, it could manifest in a number of ways.
Signs and symptoms of an allergic reaction may include any combination of the following:
- eyes: red, itchy, swollen, watery;
- nose: sneezing, aching, stuffy runny and/or congested with post nasal drip nose, or a sore throat, hoarseness of voice, headaches;
- lungs: coughing, wheezing, tightness in chest or shortness of breath;
- inflammatory Response: skin irritation, redness, itching, swelling, blistering, weeping, crusting, rash, eruptions, hives (itchy bumps or welts) swelling of the face, neck, eyelids, lips, tongue;
- gastrointestinal Distress: bloating, nausea, emesis (vomiting), diarrhea, mild to severe pain;
- other: fatigue, malaise, dizzy or lightheadedness;
- just to name a few…
- low blood pressure (hypotension) a rapid, weak pulse;
- constriction of your airways, a swollen tongue, or throat, which can cause wheezing and trouble breathing;
- a skin rash including hives, itching, flushed or pale skin;
- nausea and vomiting;
- dizziness or fainting.
In closing, As time passes, doctors, specialists, clinicians, researchers and patients alike are finding a correlation between many of the disease, we once believed we understood, allergic reactions, the autoimmune system and the pain discomfort we have come to learn to live with. When watching what we ingest be it through oral ingestion, breathing it in or absorbing it through our skin is the key to feeling even a little bit better isn’t it worth it?
