Is it possible to develop new allergies in adulthood?

Understanding Adult-Onset Allergies

New allergies can develop in adulthood due to various factors, including changes in environmental exposure, lifestyle, and immune system function. A significant proportion of adults, approximately 30%, develop allergies after the age of 18. This phenomenon is often linked to increased sensitivity to specific allergens, such as pollen, dust mites, or pet dander.

Symptoms and Diagnosis

Adult-onset allergies can manifest as respiratory issues, skin rashes, gastrointestinal problems, or even anaphylaxis. To diagnose adult-onset allergies, healthcare professionals typically conduct skin prick tests, blood tests, or elimination diets to identify the triggering allergen. Symptoms can be subtle, making accurate diagnosis crucial for effective treatment.

Managing Adult-Onset Allergies

If an adult-onset allergy is diagnosed, the primary focus is on avoiding exposure to the allergen and using medication to manage symptoms. An EpiPen or other epinephrine auto-injector may be prescribed for severe reactions, such as anaphylaxis. Patients with tree nut or peanut allergies are at higher risk for anaphylaxis and should carry their EpiPen with them at all times.
