Allergies can cause symptoms like sneezing, rashes, redness, itching, and possibly pain. Allergies are caused by foods, genetics, hygiene factors, and acute responses to allergens. Allergens can be diagnosed through skin testing or blood testing. Prevention includes avoiding pollens, molds, mosquitoes, bees, and pharmacotherapy or immunotherapy treatment. Allergens can be inhalant allergens from the air, ingestant allergens from food, contactant allergens that touch the skin or mucosa, or allergens from injections, insect venom, microorganisms, physical factors, and environmental pollutants.
