Think allergies only start in childhood? You can actually develop allergies later in life, even if you’ve never had them before. Adult-onset allergies can be triggered by things like pollen, dust mites, pets, or certain foods, and may cause symptoms such as sneezing, congestion, itchy eyes, or coughing. If you’ve noticed new or worsening allergy symptoms, it may be worth talking with a provider to identify the cause and find the right treatment plan.
