Allergy symptoms vary greatly depending on severity and what type of allergen is triggering symptoms. For example, the most severe type of allergic reaction is called anaphylaxis, which is a whole-body allergic reaction that impairs breathing and causes a drop in blood pressure and heart rate. Most allergy symptoms, however, are merely an uncomfortable or inconvenient itching, swelling or sneezing. Here is a list of common North Sioux City allergens and the symptoms associated with them:
The most common foods that cause allergy symptoms are eggs, milk, peanuts, tree nuts, fish, shellfish, wheat, soy and certain seeds. Most food-related allergy symptoms occur within two hours of ingestion, but they can also occur within minutes. Some food allergy symptoms include vomiting, stomach cramps, hives, shortness of breath, wheezing, coughing, circulatory collapse, hoarse voice, swollen throat and tongue, weak pulse, pale skin, dizziness and anaphylaxis.
Skin allergies commonly present as bumps, redness, dryness and itchiness. Skin allergies can also overlap with food allergies as some people have contact allergies to certain foods. Common skin allergies include atopic dermatitis, which is a common form of eczema; hives, which can be caused by an allergen or an infection; contact dermatitis, which is a rash that can be caused by soaps, detergents, shampoos, nickel, adhesives and latex; and latex allergies, which can present as dermatitis (hives), itching, stuffy or runny nose and asthma.
Hay fever, also called allergic rhinitis, affects between 40 and 60 million Americans. It can be seasonal, only occurring during the spring and summer due to airborne pollen, or perennial, caused by dust mites, dander or mold. Hay fever symptoms include runny nose, itchy eyes and skin, sneezing, runny or stuffy nose and fatigue.
