Allergies occur when the immune system overreacts to normally harmless substances (allergens), releasing chemicals like histamine that cause inflammation and symptoms. Common allergens include pollen, dust mites, pet dander, certain foods, insect venom, medications, and mold. Travelers may experience new or worsened allergies due to exposure to different plants, foods, or environmental factors in Mexico. Symptoms range from mild (sneezing, runny nose, itchy eyes) to severe (hives, swelling, difficulty breathing, anaphylaxis). Prompt treatment helps prevent progression to more serious reactions and improves quality of life during travel. Diagnosis typically involves medical history review and sometimes skin or blood tests to identify specific allergens. Treatment options include antihistamines, decongestants, nasal corticosteroids, bronchodilators for respiratory symptoms, and in severe cases, injectable epinephrine. Allergists can also provide strategies for allergen avoidance and may recommend immunotherapy for long-term management. Mexico has highly trained allergists, particularly in major cities and tourist areas, often at lower costs than in the US.
