Can Allergies Develop In Adulthood
While the majority of allergies present themselves in childhood, adults are not immune to the onset of allergies.
Allergies to any substance can develop, even well into adulthood. More than 18 million Americans suffer from hay fever, and an even larger number develop allergies to environmental substances such as pet dander or dust. Foods and medications also present problems even for grown adults.
Why Do Allergies Strike In Adulthood
Your adult-onset allergies arent a fluke. Its possible to develop an allergy to any substance at any point during your life. Whats more, the number of people with adult-onset allergies is growing.
Experts in the field arent yet sure why allergies strike in adulthood. There seems to be a genetic component, though. If you have close family members with allergies, youre more likely to develop allergies yourself, whether in childhood or adulthood.
In some cases, environmental triggers may alter the way your immune system responds to different substances. Having an existing allergy raises the risk that you may develop a new allergy. While the exact reasons remain unknown, we do know that the immune system continues to change over time.
Why Adults Develop Allergies
A lot of people think that youre born with allergies or can only develop them during early childhood. But the truth is that a lot of people develop allergies during their 20s, 40s and even beyond suddenly becoming sensitive to certain foods or things in their environment like ragweed and mold. Why? The truth is that doctors dont really know why adults develop allergies, but they do have some theories.
Are These Symptoms Allergies
If you believe you have developed allergies, the first thing you can try is over-the-counter antihistamines to help control your symptoms. It is also a good idea to avoid the things you believe you are allergic to until you can be seen by an allergist.
An allergist can perform allergy testing to determine if you have allergies and exactly what is triggering your allergy symptoms. If testing confirms you have allergies, you can work with your doctor to develop a personalized treatment plan.
What Happens In Your Body When You Have Allergies
Millions of people in the U.S. suffer from seasonal allergies. And, if you notice symptoms like itchy eyes and a stuffy nose after spending time outside, youre probably one of them.
These types of symptoms happen when your bodys immune system kicks into high gear and overacts to something in your environment. In the case of seasonal allergies, common allergens like pollen and mold cause the immune system to produce antibodies called Immunoglobulin E .
These IgE antibodies carry messages to the cells in your eyes, nasal passages, throat and airways to release the chemical histamine. When this happens, an inflammatory response is triggered and you experience those annoying allergy symptoms.
Common seasonal allergy symptoms
- Dark circles & puffiness under eyes
- Stuffed up & runny nose
- Scratchy & sore throat
An allergic reaction is essentially your bodys way of protecting you from what it believes to be dangerous foreign invaders. By triggering an inflammatory response, your body is attempting to block allergens while also triggering an immune response to ward off possible infection.

You Might Have Allergy Symptoms For The First Time Ever This Spring Here’s Why
After months of bare trees and snow, Spring is a welcome change but with gorgeous blooms come the itchy, watery, stuffy symptoms of seasonal allergies. And now, that might be true even if you’ve never suffered from allergies before.
“Climate change is making allergies worse,” Amiinah Y. Kung, MD, an allergy and immunology specialist at Northwestern Medicine Central DuPage Hospital, told POPSUGAR. “Winters aren’t as cold, so there isn’t much of a freeze, and with seasonal warming beginning earlier, it makes Spring particularly bad.” A longer, harsher season can mean that some people develop symptoms for the first time, while others simply feel worse.
Pollution also plays a role in this trend. “Pollutants like smog and carbon dioxide interact with pollen, which can make your reaction to it worse,” Dr. Kung explained. But pollution also puts stress on the plants themselves. “They release more pollen to make sure they reproduce, and the pollen becomes more potent,” she said.
So, the probability that your itchy throat or runny nose is a symptom of seasonal allergies even if you’ve spent much of your life allergy-free is relatively high. “Each year you’re exposed to allergies, you have the potential to develop more of them,” Dr. Kung said.

Q: Is It True That A Child Has To Be At Least 2 In Order To Develop Allergies
A: For a long time many doctors believed that babies under 2 couldn’t develop allergies because their immune systems were not developed enough. But now we know that’s not true. A baby can have an allergic reaction to almost anything she’s exposed to on a consistent basis, including dust, mold, pet dander, or even certain foods.
On the other hand, seasonal allergies tend to manifest later because it takes at least one allergy season for a baby’s immune system to “learn” to be allergic to them. Depending on when your baby was born, you’re not likely to notice seasonal allergies earlier than 12 to 15 months.
The symptoms of allergies in babies and young children include a runny nose with clear mucus, itchy, watery eyes, sneezing, hives, and dark circles under the eyes . If you suspect your child has allergies, talk to your pediatrician. If your child is diagnosed with allergies, your doctor may suggest you see an allergy specialist, but most pediatricians can manage mild to moderate allergies very well with over-the-counter antihistamines like Zyrtec or Claritin .
Is There Anything Else I Should Know About Seasonal Allergies
Yes. Scientists have recently determined that because of climate change, pollen season is likely to become longer and feature even higher amounts of pollen than it does currently. Right now in the US, it generally starts in mid-April and peaks in early May by 2020, it’ll begin in mid-March, peak in April, and continue even later into the summer, with higher amounts of pollen in the air at any given time.

Can I Develop Seasonal Allergies Over Time And Can They Go Away
Yes and yes.
Most people with seasonal allergies develop them some time after reaching adulthood, and these allergies can change unpredictably in some cases, disappearing one spring after years of suffering. But scientists still really have no idea how or why this happens. Claims that you can eliminate seasonal allergies by changing your diet are unsubstantiated.
What Are Seasonal Allergies
Seasonal allergies are reactions to things that are only around during certain times of the year. These are also known as pollen allergies or hay fever.
Pollen is a powdery substance that plants release to reproduce. When a person has a pollen allergy, their body reacts to the pollen as a foreign substance, then attacks it.
Seasonal allergies affect a person only during certain seasons. For instance:
- Tree pollen: If your child has an allergy to tree pollen, they will have allergy symptoms in the spring.
- Grass pollen: If they have a grass pollen allergy, their symptoms will occur in the summer.
- Weeds and mold: Weed pollen and mold spore allergies crop up in the fall.
Some people have allergies to all kinds of pollen. If your child has tree, grass, weed, and mold allergies, seasonal allergies may bother them for much of the year.

Can Allergies Stop On Their Own
A question commonly asked at diagnosis is how likely is it that my allergy will improve with time? The severity and types of symptoms you had at your initial reaction and the number of foods to which you are allergic can help predict your chances of outgrowing the allergy. In addition, we know that milk, egg and soy allergies most often improve with time while peanut, tree nut, fish and shellfish are less likely to improve.
Its not recommended you simply assume that youve outgrown a reaction to an allergen instead, you should visit an allergist for testing. For food allergies, if your test results indicate that it is safe, you will participate in an in office oral food challenge to determine if you still have symptoms.
When To See A Doctor
Some allergy symptoms are mild and can be treated with reduced exposure to the allergen or by taking medication.
But some symptoms are severe enough to disrupt your life, or even life threatening.
Seek emergency medical help, or have someone around you get help if you notice any of the following symptoms:
- feeling abnormally dizzy
- abnormal swelling of the tongue or throat
- rash or hives across your body
- abdominal cramps

Why Does This Happen
It isnt exactly clear why allergies might develop in adulthood.
Researchers believe that a severe allergic reaction during childhood, even a single episode of symptoms, can increase your likelihood of developing allergies as an adult when youre re-exposed to that allergen at higher levels.
In some cases, these links are easy to see and represent what is known as the atopic march. Children who have food allergies or skin conditions like eczema may develop symptoms of seasonal allergies, like sneezing, itching, and sore throats, as they get older.
Then, symptoms fade for a while. They may return in your 20s, 30s, and 40s when youre exposed to an allergy trigger. Possible adult allergy triggers can include:
- Allergen exposure when your immune system function is reduced. This happens when youre sick, pregnant, or have a condition that compromises your immune system.
- Having little exposure to an allergen as a child. You may not have been exposed to high enough levels to trigger a reaction until adulthood.
- Relocating to a new home or workplace with new allergens. This could include plants and trees that you werent exposed to before.
- Having a pet for the first time.Research suggests this can also happen after a long period of having no pets.
Why Do Some People Suffer From These Allergies While Others Don’t
The short answer: we really don’t know.
Genetics are at least part of the reason having a parent with a pollen allergy makes it more likely you’ll have one as well. And scientists have begun identifying some genes that seem to be linked to the condition.
But it’s clear environmental factors play a role in determining whether you’ll experience allergies, as well. In the United States, rates of all sorts of allergies have been increasing in recent years, especially in children. Many scientists blame this on something called the hygiene hypothesis the idea that growing up in an overly clean, sterilized environment somehow messes with the natural development of the immune system, making it more prone to errors, like mistaking a harmless pollen grain for an invader.

Allergies Take Time To Develop
Even though it may seem like your childs symptoms popped up suddenly, allergies actually take time to develop in children, pediatric allergist Kathryn Ruda Wessell, DO, says.
Allergic rhinitis can be caused by either an indoor or outdoor allergen, Dr. Wessell says. With outdoor allergens, you have to live through the season a few times to become sensitized. We tend to see outdoor triggered seasonal allergy symptoms in children after age 3, classically ages 5 to 6. Indoor allergen triggered symptoms can be seen earlier, as early as 1 year of age because of things theyre exposed to in the home on a regular basis, such as dust mites and pets.
According to Dr. Wessell, some people are exposed to a foreign substance or allergen and have no symptoms, while others come into contact with an allergen and have allergic reactions, including a runny nose, watery eyes and sneezing.
Age also matters. Allergic reactions that are triggered by allergens, such as pollen, dust or pets are more common in children up to 20 years old. After that, its usually thought to be non-allergic rhinitis, which isnt caused by allergens, but rather by substances like smoke, chemicals, environmental irritants, hormonal changes and/or physical defects of the nose.
The way that allergies evolve in children even has a name, says Dr. Wessell.
The allergic march includes these conditions:
These four diseases can overlap or appear in different order in a childs life, Dr. Wessell says.
When Does A Person Develop Allergies
Allergies can develop at any point in a persons life. One factor that increases your chance is your family history. If one parent is allergic there is a 30-50% chance of their offspring developing allergies. This jumps to 60-80% if both parents are allergic.
In many cases, allergies first present early in life, during infancy or the toddler years. Most of these allergies will be lifelong concerns, although some can resolve on their own.

Can Allergies Be Prevented
Unfortunately, you cannot prevent the manifestation of adult-onset allergies. As we mentioned, these allergies sometimes spring up where none existed before. Other times, exposure to the allergen triggers a reaction. For those reasons, its difficult to say with certainty which triggers you should avoid.
While you cant always prevent adult-onset allergies, you can treat them as they develop. If, for instance, you notice you get an adverse reaction after eating shellfish or peanuts, you should refrain from eating these foods right away. Instead, set up an appointment with an allergy provider who can test your to see what is causing your symptoms
In the case of food allergies, the best treatment is avoidance. For pet dander, pollen, and other standard allergy triggers, you can try medications, including steroid nasal sprays and antihistamines, to alleviate uncomfortable symptoms. You can also try to keep yourself away from these allergens via lifestyle adjustments.
It’s Not Just You Who’s Suddenly Having Seasonal Allergies
The World Allergy Organization reports that the prevalence of allergies has risen in industrialized countries over the past 50 years. In 2018 alone, more than 19 million adults in the U.S. were diagnosed with hay fever , according to the CDC. Meng Chen, M.D., an allergist at Stanford Universitys Sean N. Parker Center for Allergy and Asthma Research, says her office is seeing more cases each day. Its something I oftentimes hear from patientsIve never had allergies, and all of a sudden, I, an adult, have developed all of these allergies, she says. What the heck is going on?
For one thing, the world is warming up, and that leads to longer allergy seasons as much as 27 days longer, according to the Asthma and Allergy Foundation of America. Then theres all the moving around we dothe average 30-year-old will have already moved about six times in their life. If some resident in your building has cats, or your new bedroom faces a field of sagebrush, you may develop a reaction youve never experienced before.

What Questions Should Allergy Sufferers Ask When Speaking To Their Doctor About Their Symptoms
First, patients should share their symptoms with their doctor to see if they are compatible with seasonal allergies as opposed to a medical condition that may look like allergies, such as chronic sinusitis. Then, the patient should ask about creating an action plan and what medication is most likely to work best for them. There are many treatment options like oral medications, nasal sprays or allergen immunotherapy depending on each individual patient.
How Do Adult Onset Allergies Develop
If youre predisposed to a certain type of allergy, but youve never been around that allergen before, it can seem like your symptoms have materialized out of nowhere. Say, for instance, you never had pets growing up. Youre allergic to pet dander, but youd never know it. Then, your roommate decides to get a dog, and your allergies start going crazy.
So yes, even though it may seem like you just woke up with allergies one day, theres usually a medical explanation for why its happened. Unfortunately, that explanation can be difficult to pinpoint, especially when youre simply becoming aware of an allergy you may have had for some time.
In other cases, allergies do develop on their own. You may notice changes suddenly, or monitor a gradual shift in your reaction to a specific substance. Adult onset allergies typically develop differently in different people.
