While allergies often develop in childhood, it’s not uncommon for some people to start experiencing allergy symptoms in their 20s or 30s.
How Allergies Develop
Allergy development happens in two stages. In the first stage, your body encounters a harmless substance, such as pollen, but mistakenly identifies it as a threat. In response, your immune system creates antibodies known as IgE to combat this substance.
The second stage occurs upon repeated exposure to the same allergen. The allergen binds to the IgE antibodies, which triggers allergic reactions like sneezing, watery eyes and congestion.
Common Adult Allergy Triggers
Some of the most frequent allergens that can trigger symptoms in adults include:
- Pollen
- Pet dander
- Certain foods like shellfish, tree nuts and soy
Why Do Allergies Develop in Adulthood?
If you never experienced allergies as a child but now find yourself reacting to pollen while walking on your favorite trail, you may wonder what’s changed. While the exact cause behind adult-onset allergies remains unclear, several factors could be at play, including:
- Moving to a new area where you’re exposed to unfamiliar allergens.
- Getting a pet for the first time.
- Limited exposure to certain allergens during childhood.
- Encountering allergens when your immune system is weakened.
Managing and Preventing Adult-Onset Allergies
The type and severity of your allergies will influence how you manage and prevent symptoms.
The best way to avoid allergy symptoms is by minimizing exposure to the allergens that trigger them. This might include:
- Steering clear of foods that contain allergens.
- Staying indoors with windows closed during high pollen seasons.
- Using a dehumidifier to reduce moisture and allergens in your home.
- Keeping your home free of dust by cleaning and vacuuming regularly.
For some, avoiding allergens entirely isn’t always possible. In these cases, over-the-counter medications like antihistamines or decongestants can help control symptoms.
When to See an Allergist
If over-the-counter treatments aren’t providing relief or you’re unsure what’s triggering your symptoms, it’s a good idea to consult an allergist. They can perform skin or blood tests to identify your specific allergens and provide treatment options.
In cases where typical medications don’t work, your allergist may recommend immunotherapy. This treatment involves gradually introducing small amounts of the allergen to your system to build up your tolerance. Immunotherapy is most commonly administered through allergy shots, but oral allergy drops may also be an option.
