Can You Get Rid of Allergies Forever? What the Science Says

Are Allergies Permanent?

If you’ve ever asked, “Can I get rid of allergies forever?”, the answer depends on the type of allergy, its severity, and how your immune system adapts over time.

Some people—especially children—outgrow certain allergies, while others experience symptoms for life. Understanding what causes allergies and how treatments like immunotherapy work can make all the difference.

Why Do Allergies Develop?

Allergies occur when your immune system overreacts to harmless substances such as pollen, pet dander, or food proteins. When this happens, the body releases histamines, leading to symptoms like sneezing, itching, nasal congestion, and watery eyes.

Common allergy triggers include:

• Seasonal: Pollen, grass, ragweed, and mold
• Pet-related: Dander from cats, dogs, or other animals
• Food: Nuts, dairy, shellfish, or gluten
• Environmental: Dust mites, smoke, and fragrances

Can You Outgrow Allergies?

Yes — in some cases. Children often outgrow milk, egg, or soy allergies as their immune systems mature. However, most seasonal, pet, and environmental allergies tend to persist into adulthood.

Factors that influence whether allergies fade include:

• Age: Younger immune systems adapt more easily
• Exposure frequency: Regular low-level exposure may desensitize the immune system
• Immune system changes: Illness, hormones, or stress can alter reactions

Can Allergies Be Cured?

There’s no guaranteed “permanent cure,” but modern treatments can reduce or even eliminate symptoms long-term — especially with allergy immunotherapy.

Best Treatments for Long-Term Allergy Relief

1. Allergy Shots (Subcutaneous Immunotherapy)

• Gradually desensitizes your immune system to specific allergens
• Involves a series of small injections over several months
• Can provide relief that lasts years after treatment

2. Sublingual Immunotherapy (SLIT)

• Allergy tablets dissolved under your tongue
• Convenient, needle-free alternative for certain allergens

3. Medications

• Antihistamines for sneezing and itching
• Nasal sprays for congestion
• Decongestants for short-term symptom control

4. Environmental & Lifestyle Strategies

• Use HEPA air purifiers and hypoallergenic bedding
• Shower before bed during high-pollen days
• Limit outdoor exposure when air quality is poor

5. Diet & Immune Health

A nutrient-rich diet, adequate sleep, and stress management help your immune system function properly—reducing allergic flare-ups.

When to See a Doctor

You should schedule a visit with your primary care provider or allergist if you:

• Have persistent or worsening symptoms despite medication
• Experience shortness of breath, wheezing, or frequent sinus infections
• Want to explore immunotherapy or personalized allergy testing

At BASS Medical Group, our Primary Care Providers and Allergy Specialists offer advanced diagnostic testing and customized treatment plans to help you breathe easier year-round.

Frequently Asked Questions

1. Can allergies go away naturally?

Yes. Some food allergies—especially in children—may fade with time. Environmental allergies, however, usually persist unless treated.

2. What’s the closest thing to a permanent cure for allergies?

Allergy immunotherapy (shots or tablets) can desensitize your immune system, offering long-term relief that may last even after treatment ends.

3. Does diet affect allergies?

Yes. Eating anti-inflammatory foods, staying hydrated, and reducing processed sugar can support immune balance and reduce flare-ups.

4. Can adults suddenly develop allergies?

Absolutely. Allergies can appear at any age due to immune changes, new exposures, or hormonal shifts.
