Many people believe that allergies are something you are born with or develop in childhood. While this is often true, it is also possible to develop new allergies as an adult. Suddenly reacting to a food you have always eaten or getting seasonal sniffles for the first time can be confusing. A key part of understanding adult-onset allergies is recognizing that your immune system can change over time. This guide will explore why allergies can appear later in life, the common triggers, and when it is time to see a specialist, such as an allergist, for proper diagnosis and management. At Doral Health & Wellness, we have all the answers you need.
Why Do Adults Suddenly Develop Allergies?
Developing an allergy as an adult can feel random, but there are several theories about why it happens. An allergy occurs when your immune system mistakenly identifies a harmless substance, like pollen or a certain food, as a threat and overreacts. While the exact cause for this shift in adulthood is not always clear, several factors may play a role.
Key contributing factors include:
- Significant Life Changes: Major life events that impact the immune system, such as a severe illness, pregnancy, or extreme stress, can sometimes trigger the development of new allergies.
- A Change in Environment: Moving to a new geographic location can expose you to different types of pollen, mold, or other environmental allergens that your body has never encountered before. This new exposure can sometimes lead to an allergic reaction.
- Reduced Exposure in Childhood: Some theories suggest that a lack of exposure to certain microbes and allergens in early childhood may make the immune system more likely to overreact to them later in life.
- Viral or Bacterial Infections: A significant infection can sometimes reset or alter the immune system’s responses, leading it to become sensitive to new allergens.
The Most Common Adult-Onset Allergies
While it is possible to develop an allergy to almost anything, some types are more common to see emerge in adulthood. Recognizing the most common adult-onset allergies can help you identify potential triggers for your new symptoms.
Environmental Allergies (Allergic Rhinitis)
This is perhaps the most frequent type of adult-onset allergy. Often called hay fever, it is triggered by airborne substances.
- Pollen: You might suddenly start reacting to tree, grass, or weed pollen, leading to classic seasonal allergy symptoms like sneezing, itchy and watery eyes, and a runny nose.
- Dust Mites: These microscopic creatures are common in households and can trigger year-round allergy symptoms.
- Mold: Exposure to mold spores, either indoors or outdoors, can cause allergic reactions.
- Pet Dander: It is not uncommon for someone who has lived with pets for years to suddenly develop an allergy to cats or dogs.
While most food allergies develop in childhood, they can appear at any age. Shellfish is one of the most common food allergies to develop in adulthood. Other common culprits include fish, tree nuts, and peanuts. Symptoms can range from mild itching in the mouth to a severe, life-threatening reaction called anaphylaxis.
Skin Allergies (Contact Dermatitis)
This type of allergy occurs when your skin comes into direct contact with an allergen, leading to an itchy, red rash. Common triggers for adult-onset skin allergies include:
- Nickel: A metal often found in jewelry, buckles, and buttons.
- Fragrances and Preservatives: Chemicals in perfumes, lotions, and cosmetics can trigger a reaction.
- Latex: Found in gloves and other products.
Diagnosing and Managing Adult-Onset Allergies
If you suspect you have developed a new allergy, self-diagnosing can be difficult and unreliable. The best course of action is to consult a board-certified allergist. A specialist can perform tests to accurately identify your triggers.
The Diagnostic Process
- Skin Prick Test: This is the most common allergy test. A tiny amount of a potential allergen is placed on your skin, which is then lightly pricked. If you are allergic, a small, raised bump similar to a mosquito bite will appear.
- Blood Test: A blood test can measure the amount of specific allergy-causing antibodies (IgE) in your bloodstream.
- Patch Test: For suspected skin allergies, patches with various allergens are applied to your back for 48 hours to see if a rash develops.
Treatment Options
Once your allergens are identified, a specialist at an immunology clinic in Brooklyn can develop a personalized management plan.
- Avoidance: The first step is to avoid or minimize your exposure to the identified allergens.
- Medications: Over-the-counter or prescription antihistamines, nasal sprays, and eye drops can help manage symptoms.
- Allergen Immunotherapy (Allergy Shots): For severe environmental allergies, this treatment involves regular injections with small amounts of the allergen to desensitize your immune system over time.
