What Should I Do If I Develop Adult Onset Allergies

Why do people have seasonal allergies? – Eleanor Nelsen

If you believe you have developed allergies as an adult, avoid any suspected allergens while you are waiting to see your allergist. Your allergist may order some tests such as blood or skin tests to further evaluate your allergies.

If allergy testing confirms a diagnosis of allergy, your allergist will work with you to develop a treatment plan including avoidance measures, medications, and/or other treatment options such as immunotherapy for environmental allergies.

Are Allergies Worse In Childhood Or Adulthood

Per the American College of Allergy, Asthma & Immunology and 2013 data, 28 million kids across the United States have allergies. As many as 50 million adults may get reactions to allergens as well.

While more adults have allergies in the United States than children, is there an age group that has it worse? Research that appeared in a 2012 article at MassGeneral Hospital for Children in Massachusetts suggests that adults may be the most at risk for intense, serious symptoms. Adult behaviors such as taking certain medications and drinking alcohol may increase risk for severe anaphylaxis. Exercise and having asthma can also increase reaction severity. Of course, young children who cannot communicate symptoms can also have severe reactions which go unnoticed and progress to dangerous levels.

A severe allergic reaction, which can be triggered by foods or venom , is called anaphylaxis. This is a life-threatening emergency condition in which the patient goes into shock, cannot breathe, and may have vomiting, nausea, and skin rashes. Anaphylaxis can occur instantaneously or sometimes minutes after eating an allergen or being stung. Epinephrine can control cases of anaphylaxis that are caught immediately. The longer the patient goes without treatment, the greater the likelihood that death can occur. For this reason patients with a history of severe anaphylaxis are encouraged to always have an in date epinephrine injector available.

Effective Treatments Are Available

Seek advice from your pharmacist or doctor about medications that will relieve your symptoms. Although medications do not cure allergies, they are much more effective with few side effects. It is important to use them correctly, and to avoid medications that can cause problems such as frequent decongestant nose sprays or tablets.

Antihistamine tablets or syrups help to reduce symptoms , but they are not as effective in controlling severe nasal blockage and dribble. The advantage of antihistamines is their flexibility you can take them when you have symptoms, and avoid them when you are well. Antihistamine eye drops can also be helpful in controlling watery eyes due to allergies.

Intranasal corticosteroid nasal sprays have a potent action on inflammation when used regularly . These need to be used regularly and with careful attention to the way in which they are used. Different brands of INCS vary in strength and effectiveness, so it is important to read the labels and check details with your pharmacist or doctor.

Combination medications containing an antihistamine and intranasal corticosteroid nasal spray are available and offer the combined advantages of both medications.

unblock and dry the nose, but should not be used for more than a few days as they can cause long term problems in the nose

Natural products such as salt water nasal sprays or douches can be effective in relieving symptoms.

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.

How Are Allergies Treated

There’s no cure for allergies, but symptoms can be managed. The best way to cope with them is to avoid the allergens. That means that parents must educate their kids early and often, not only about the allergy itself, but also about the reactions they can have if they consume or come into contact with the allergen.

Telling all caregivers about your child’s allergy is also important.

If avoiding environmental allergens isn’t possible or doesn’t help, doctors might prescribe medicines, including antihistamines, eye drops, and nasal sprays.

In some cases, doctors recommend allergy shots to help desensitize a person to an allergen. But allergy shots are only helpful for allergens such as dust, mold, pollens, animals, and insect stings. They’re not used for food allergies.

Airborne Allergies

To help kids avoid airborne allergens:

  • Keep family pets out of your child’s bedroom.
  • Remove carpets or rugs from your child’s room .
  • Don’t hang heavy drapes and get rid of other items that allow dust to build up.
  • Clean when your child is not in the room.
  • Use special covers to seal pillows and mattresses if your child is allergic to dust mites.
  • If your child has a pollen allergy, keep the windows closed when pollen season is at its peak, have your child take a bath or shower and change clothes after being outdoors, and don’t let him or her mow the lawn.
  • Keep kids who are allergic to mold away from damp areas, such as some basements, and keep bathrooms and other mold-prone areas clean and dry.

What Is Food Intolerance

A food intolerance isn’t the same as a food allergy.

People with food intolerance may have symptoms such as diarrhoea, bloating and stomach cramps. This may be caused by difficulties digesting certain substances, such as lactose. However, no allergic reaction takes place.

Important differences between a food allergy and a food intolerance include:

  • the symptoms of a food intolerance usually occur several hours after eating the food
  • you need to eat a larger amount of food to trigger an intolerance than an allergy
  • a food intolerance is never life threatening, unlike an allergy

Can You Develop Allergies Later In Life

It is certainly possible to develop allergies in adulthood. Adult-onset allergies can occur seemingly out of nowhere due to exposure to new allergens in the environment, family history and changes in the immune system. The most common food allergies in adults are peanuts, fish, shellfish such as shrimp, lobster and tree nuts .

Theres no way to avoid getting adult-onset allergies if youre susceptible to them, since you cant reasonably expect to know every trigger that could cause an allergic reaction and then avoid it. In addition, there is some recent research that indicates avoiding allergens can make it more likely for an individual to develop allergies, because the immune system is unfamiliar with more substances.

What Are The Signs And Symptoms Of Allergies

The type and severity of allergy symptoms vary from allergy to allergy and person to person. Allergies may show up as itchy eyes, sneezing, a stuffy nose, throat tightness, trouble breathing, vomiting, and even fainting or passing out.

Kids with severe allergies can be at risk for a sudden, potentially life-threatening allergic reaction called anaphylaxis. Anaphylaxis can happen just seconds after being exposed to an allergen or not until a few hours later .

So doctors will want anyone diagnosed with a life-threatening allergy to carry an epinephrine auto-injector in case of an emergency. Epinephrine works quickly against serious allergy symptoms for example, it reduces swelling and raises low blood pressure.

Airborne Allergy Symptoms

Airborne allergens can cause something known as allergic rhinitis, which usually develops by 10 years of age, reaches its peak in the teens or early twenties, and often disappears between the ages of 40 and 60.

Symptoms can include:

  • swelling
  • a drop in blood pressure, causing lightheadedness or loss of consciousness

Allergic reactions can vary. Sometimes, a person can have a mild reaction that affects only one body system, like hives on the skin. Other times, the reaction can be more serious and involve more than one part of the body. A mild reaction in the past does not mean that future reactions will be mild.

Dealing With Nonallergic Rhinitis

Why Do Some Get People Allergies And Others Dont?

Start by trying to avoid known triggers. If a drug is the culprit, ask your doctor about trying an alternative.

If you cant avoid the trigger, first see whether a daily saline rinseoften applied using tools such as neti pots or bulb syringeshelps ease your symptoms.

You can also consider using a spray that contains the prescription nasal antihistamine azelastine . Steroid sprays can also work well for persistent symptoms.

Eating Disorders As Food Allergies

Becoming too restrictive with your diet can be a red flag for an eating disorder. For the individual who has an eating disorder, claiming a food allergy may tap into the structure and rigid control that is inherent to an eating disorder.

If you have a good food/ bad food mentality, then those foods that fall into the category of bad, may elicit efforts to avoid them. How do you know if your relationship with food is unhealthy? Having many food rules such as “no sugar,” “no carbs,” or “no food additives” may be one sign of a disrupted food relationship.

If you cant be trusted around food, or if you routinely berate yourself after you indulge, you may be showing signs of an eating disorder. Other signs include a desperate desire to be thin, controlling every morsel of food you eat, and over-exercising.

Penicillin Skin Sensitivity Testing

Penicillin skin sensitivity testing can help to confirm the safety of the drug and qualm fears of a dangerous drug reaction. A positive skin test indicates the presence of IgE antibodies to penicillin and immediately excludes the use of it and related ß-lactam antibiotics. For non-penicillin ß-lactams, the immunogenic determinants that are produced by degradation are unknown, and diagnostic skin testing is of limited value.

Climate Change And The Pandemic Are Playing A Huge Role

Year over year, were finding climate change is a major factor in worsening symptoms for spring and fall pollen seasons, said Kenneth Mendez, the CEO and president of the Asthma and Allergy Foundation of America.

The rising temps and increasing CO2 concentrations in the atmosphere are making pollen seasons heavier and longer. Allergy season is now 10 days longer than it was in 1990, and trees, grass and weeds are producing 21% more pollen. More pollen means more runny noses, watery eyes and itchy throats.

Unfortunately, we are seeing an increase in pollen counts on a yearly basis, and this is due to global warming and an increase in CO2, which we know plays a role in higher pollen counts, said Payel Gupta, an allergist and immunologist and medical director of the at-home allergy clinic Cleared.

The recent warm weather were seeing this year and in the past few years is to blame. Plants bloom in warm weather, then tree, grass and weed pollen pick up and fly into the air around us.

In the past, warm weather didnt appear until April or so, delaying pollen-producing plants from blooming. But its been getting warmer earlier year after year. Some areas in the Northeast saw 70-degree days as early as January this year. On top of that, the first freeze we typically see each fall is happening later in the year. Mendez said this keeps flowering pants like ragweed a major source of allergies alive and well.

Common Seasonal Allergy Triggers

Why Do I Suddenly Have Allergies?

If you sneeze and cough during certain times of the year, you may have seasonal allergies. However, occasional allergies arent something you just have to live with.

In many areas of the United States, spring allergies begin in February and last until the early summer. Tree pollination begins earliest in the year followed by grass pollination later in the spring and summer and ragweed in the late summer and fall. In tropical climates, however, grass may pollinate throughout a good portion of the year. Mild winter temperatures can cause plants to pollinate early. A rainy spring can also promote rapid plant growth and lead to an increase in mold, causing symptoms to last well into the fall.

The most common culprit for fall allergies is ragweed, a plant that grows wild almost everywhere, but especially on the East Coast and in the Midwest. Ragweed blooms and releases pollen from August to November. In many areas of the country, ragweed pollen levels are highest in early to mid-September.

Other plants that trigger fall allergies include:

  • Burning bush
  • Sagebrush and mugwort
  • Tumbleweed and Russian thistle

While the timing and severity of an allergy season vary across the country, the following climate factors also can influence how bad your symptoms might be:

The Relationship Between Allergies And Anxiety

The relationship between allergies and anxiety is complicated and not yet fully understood. Each person’s body reacts differently, both to allergies and to anxiety, so it’s difficult for researchers to pinpoint the causes and effects. However, there are several theories to explain the relationship between anxiety and allergies.

  • Certain allergies cause changes to the brain and body, which internally cause anxiety.
  • Living with allergies causes stress and discomfort, which may cause people to develop anxiety.
  • Allergies do not cause anxiety, but make anxiety worse.
  • Allergies have no effect on anxiety, but anxiety makes allergies worse.
  • Allergies and anxiety are independent of each other but may have some common condition between them, such as differences in immune system health.
  • Researchers have found that any one of these could potentially be true with regards to anxiety. But even more likely is that all of them are true to some extent and are simply more or less pertinent for different people.

    Why Do So Many People Have Allergies These Days

    In years past, it was the pasty-faced, sickly kid in class that had all the allergies. Today it seems everyone is allergic to something peanut butter, animals, pollen, dust, grass, and even the air we breathe.

    Why are allergies on the increase in the United States?Approximately 54 percent of the population suffers from some form of allergy, according to the American Academy of Allergy, Asthma, and Immunology. This represents a doubling according to the numbers compiled in a 1976 to 1980 study from the National Institutes of Health. In addition, allergies cost our health care system $18 billion annually, said the Allergy Relief and Learning Center.

    While the scientific community is in agreement that greenhouse gas pollution is warming the climate, might this form of pollution affect human health in ways we rarely acknowledge? Washington University Professor of Medicine H. James Wedner said the increasing concentration of carbon dioxide in the atmosphere could increase the number of people susceptible to allergies. Studies have shown that pollen, which often induces an allergic reaction, is becoming more prominent as carbon dioxide levels increase, Wedner added.

    What Allergy Treatments Are Available

    Treatments can help a great deal, says Dr. Hsu. Allergy treatment has changed over the past 10 years, with a number of first-line medications now available over the counter, she says. So, while we have lots of consultations with patients, we dont necessarily send a prescription to the pharmacy. We often advise people on what to buybut we want to be very specific, because there are certainly a lot of over-the-counter medications that we would not recommend as first-line treatments.

    For instance, she might start with antihistamines for itching and runny nose, steroid nasal sprays for nasal passage congestion, and antihistamine eye drops for ocular symptoms. If a patient is still uncomfortable, she might recommend a decongestant, but not for daily use, since its a medication patients can become overly reliant on. Likewise, some patients should avoid antihistamines that are excessively sedating, she says.

    The problem is that some people think theyll just grin and bear it. But… you can take steps to minimize those weeks of misery.Yale Medicine pediatric allergist Stephanie Leeds, MD

    Its helpful when patients have a skin or blood test to find out exactly what they are allergic to. If you are really symptomatic, its helpful to get tested at least once. I dont think you need to be re-tested year after year, but at some point, establishing the specific triggers can be helpful, because then you can take steps to avoid exposure, Dr. Leeds says.

    Allergen Immunotherapy Is A Long

    Why Do We Have Allergies?

    Medications only reduce the severity of symptoms and do not cure allergic rhinitis. Another treatment option is allergen immunotherapy which is also known as desensitisation. AIT switches off the allergic reaction, by repeatedly introducing small doses of allergen extracts, by injection, sublingual tablets, sprays or drops.

    AIT is a long term treatment which is usually given over a few years.

    It should only be started after assessment by a clinical immunology/allergy specialist to determine if this is a suitable treatment option.

    ASCIA is the peak professional body of clinical immunology/allergy specialists in Australia and New Zealand.
