Food allergy symptoms occur when your immune system reacts negatively to an otherwise harmless food. According to the University of Maryland Medical Center, about 25 percent of Americans consider themselves allergic to certain foods, while only 2 percent of adults and 4 to 8 percent of children have been properly diagnosed with such allergies. If you believe you or your child may have a food allergy, proper medical testing is recommended.
Hives, Itching or Eczema
If a bumpy rash (known as hives) or itchy, flaky skin (known as eczema or dermatitis) develop on your skin within minutes or hours after consuming a particular food or ingredient, the symptom may be indicative of a food allergy. According to the Mayo Clinic, hives, itching and eczema are some of the most common food allergy symptoms people experience. Treatment for these symptoms may involve topical creams, doctor-recommended medication or antihistamines as well as avoidance of the allergen once it has been determined.
Swelling
Swelling, or inflammation, may occur once a food allergen has been consumed. According to the University of Maryland Medical Center, allergy-related swelling commonly affects the mouth, lips, eye lids, face, tongue or other body parts (a symptom called angioedema). Over-the-counter or prescription antihistamines may be prescribed by your doctor if you experience this symptom. However, if swelling is severe and affects the airways, it may be indicative of a rare but serious allergic reaction known as anaphylactic shock. Anaphylactic shock may lead to difficulty breathing, rapid pulse, bluish skin or nail tone and, potentially, loss of consciousness.
Digestion Problems
Digestive difficulties, such as diarrhea, gas, nausea, vomiting and abdominal pain are additional common food allergy symptoms. Your doctor may prescribe pain medications and suggest re-hydration measures, if vomiting or diarrhea occur. The University of Maryland Medical Center states that many allergy-sufferers carry epinephrine, a medicinal injection prescribed by doctors to treat allergies, particularly if their allergies are severe or numerous. Regardless of medications, learning proper ways to avoid allergens is recommended for best results.
