Seasonal Allergies: Fact or Fiction with Dr. Jeff Millstein

Its important to note that most people will develop allergies as children or as young adults in their early 20s. It is rare for older adults to develop new allergies, however, its not impossible.

According to immunologist;Kanao Otsu;, most adult allergies will have existed in the individual as a child, however, the symptoms may have been minor.

After speaking with my allergist, I understood that I likely had pet allergies when I was young. At an early age, my body was resilient enough that I may not have noticed the symptoms. Over time the symptoms became stronger because the allergies werent addressed.

During my life, Ive moved a lot for work so Ive gone from dry arid environments to lush tropical environments. My body has worked to adjust to new areas and differing levels of allergens.

Ive also lived in stressful environments and taken high amounts of antibiotics due to the work Ive done. These may or may not have affected my allergies, however, stress, antibiotics, pregnancies, and major lifestyle changes will have a profound effect on your body, especially the immune system.

Things that may affect your immune system could include:

  • Lifestyle changes
  • Antibiotic use

For those who suffer from seasonal allergies, you know that this time of year can be a challenge. Flowers, trees, and grasses are in bloom and growing which means pollen and other allergens are in the air. In the U.S., an estimated 18 million adults have hay fever or allergic rhinitis, caused by pollens, weeds, grasses, and molds. Other people may have environmental allergies to things like animals and dust mites. Did you know your allergies change and this year may be the first you experience symptoms?

What Should I Do If I Develop Adult Onset Allergies

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.

Strawberry Allergies What Really Happens

People who have an allergy to strawberries often ask about the biological processes that are occurring in their bodies. The protein that causes the allergy has been identified as Fra a1or Fragaria allergen 1, and this allergen, according to a study by Christian Seutter von Loetzen et al, is found in ripe red strawberries and absent in white ones. Now, what happens is that in people who have an intolerance to strawberries, the protein Fra a1 is not recognized by the immune system. This causes the formation of Ig E antibodies that latch on to this allergen and cause the release of histamine and other inflammation causing substances. The whole cascade of released substances that follows leads to the symptoms observed in people who have allergic reactions to strawberries.

What Are The Causes

can you develop allergies later in life

Food allergies occur when the immune system reacts to a food youve eaten. Or, in severe cases, a food youve touched. Your immune system mistakenly identifies that food as something bad, like bacteria or a virus. In response, your body creates the chemical histamine and releases it into the bloodstream. Histamine can cause many symptoms that range in severity.

A food allergy isnt the same thing as a food intolerance. Food intolerance doesnt cause an allergic reaction. But, a food intolerance can cause symptoms similar to a food allergy.

Food intolerance can occur due to many factors, including food poisoning or lack of an enzyme that digests a certain component of the food. Your doctor can determine whether you have a food allergy or a food intolerance.

Can Pet Allergies Develop Later In Life

It sounds crazy, but imagine waking up one day in your 40s with allergy symptoms. You look around your house for the culprit. Maybe its the houseplants or maybe you left a window open.

Youve always kept your cat and dog in the house without a problem so you know the symptoms arent from your pets. Or are they?

If this sounds familiar, youre not alone. 10 percent of Americans are allergic to household pets and cats are 2x more likely to cause allergies than other indoor pets . Like other allergies, those caused by pets are on the rise!

Interestingly, pet allergies can develop later in life. In fact, they can develop at any time and allergies can even vanish on their own too.

In the sections below, Ill share my experience with pet allergies and the reactions I began getting at age 30. We will also discuss what can cause allergies later in life and what you can do to find relief.

Allergy Can Be Inherited

Children who have one family member with allergic diseases have a 20 to 40 per cent higher risk of developing allergy. If there are two or more family members with allergic diseases, the risk increases to 50 to 80 per cent.

Most of the time, children with food allergy do not have parents with food allergy. However, if a family has one child with food allergy, their brothers and sisters are at a slightly higher risk of having food allergy themselves, although that risk is still relatively low.

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.

  • Mouth itching and swelling
  • Runny nose and coughing
  • Vomiting and diarrhea
  • Life-threatening allergic reactions also must have trouble breathing and/or swallowing. The medical name for this is anaphylaxis. Most of these reactions have a sudden onset within 10 to 20 minutes. All occur within 2 hours of eating a certain food. People who have had this carry an emergency kit like an Epi-Pen.

What Causes Strawberry Allergies

Strawberry allergies are not fully understood. However, some research indicates that one of the primary players in strawberry allergy is linked to a protein involved with the ripening of the strawberries. This protein was named Fragaria allergen 1, or Fra a1 for short. This protein is responsible for the characteristic reddening of the strawberries as they ripen.

Who Is At Risk For Adult

Can You Actually Develop Allergies Later In Life?

Most people who are diagnosed with allergies as adults probably had an allergic episode earlier in life that they don’t remember. Often allergies follow a predictable course: eczema and food allergies in babies and toddlers, then hay fever symptoms in mid-to-late childhood. Allergy symptoms may fade during the teen years, only to return when you’re an adult.

Some people, however, do experience allergy symptoms for the first time in adulthood. This most often happens in your twenties, thirties, and forties rather than in later years. “As we age, our immune system does weaken that is why more seniors get pneumonia than 20-year-olds,” says Anthony J. Weido, MD, president of Allergy & Asthma Associates in Houston, Texas, and the Gulf Coast area. “As the immune system weakens, the hyper-allergic reaction also weakens,” he says.

Any type of allergy can occur in adulthood, including hay fever, pet allergies, and dust mite and mold allergies as well as insect bite, drug, and food allergies. Again, experts aren’t entirely sure why this happens, but theories include:

  • being exposed to allergens when the immune system is weakened, such as during an illness or pregnancy
  • not being exposed to a high enough level of the allergen as a child but reaching that threshold in adulthood
  • moving to a new location with different trees, plants, and grasses
  • getting a pet

How Do You Know If You Are Allergic To Cats

Symptoms of an allergic reaction to cats range from mild to severe, and include swollen, red, itchy, and watery eyes; nasal congestion, itchy nose, ear pain similar to pain caused by an ear infection, sneezing, chronic sore throat or itchy throat, coughing, wheezing, asthma, hay fever, hives or rash on the face or

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. suggests this can also happen after a long period of having no pets.

Avoiding Strawberry Allergy Rash

The best way to prevent an allergic reaction is to identify and avoid any foods that may trigger it, points out the Mayo Clinic. Pay attention to what you’re eating and drinking, particularly when you are not at home, and make a habit out of checking food labels.

Other ways to avoid a strawberry allergy rash include:

  • Wear a medical alert bracelet or necklace that lets others know about your condition. This may help in case you experience a severe allergic reaction and you’re unable to communicate.
  • Talk to your doctor about prescribing emergency epinephrine.
  • Be careful at restaurants and ask questions about the food served. Mention your strawberry family allergy to the server.

If you suspect you have a strawberry family allergy, speak with your doctor. In the meantime, try to avoid raw apples, apricots, almonds, cherries, raspberries, peaches, plums, quince, blackberries and other foods in the Rosaceae family. Despite their health benefits, they may trigger allergic reactions.

Can People Be Allergic To Strawberries

It is possible to be allergic to strawberries, although this allergy is much less common than many other dietary allergies.

Having a strawberry allergy means that a persons immune system reacts badly to a specific protein that is present in this fruit.

Heating strawberries will distort the proteins in them, so some people with a strawberry allergy may be able to eat cooked strawberries.

Doctors do not know how common strawberry allergies are, but, according to a small-scale study conducted in Bosnia, Europe, only 34 percent of children aged 2 and under have this allergy. The percentage drops to 0.51 percent in late childhood.

Certain foods, including strawberries, citrus fruits, and tomatoes, can cause allergy-like symptoms without a person having a true allergy to them.

People who suspect that they may have a strawberry allergy can discuss their symptoms with a doctor and possibly have an allergy test for confirmation.

Barbara 93 Years Old And Never Had An Allergy In Her Life

Barbara also recently lost her husband and moved from a large house to sheltered accommodation some way from the town where she lived most of her married life. She is now closer to her daughter and is enjoying her life but suddenly, out of the blue, she has developed a serious allergy to eggs. She cant even touch an egg now, a food she used to enjoy as a quick, healthy meal. She now fears that she is beginning to have problems with dairy too and is experimenting with soya milk to see if this brings her some relief. One of her simple pleasures was a cappuccino every day and she is really missing them and finds black coffee takes some getting used to. She has developed quite painful eczema and thinks that certain foods are contributing to its severity. She has never had any allergies before, so why is this happening? Her doctor told her he has never seen someone in their 90s who suddenly got food allergies. Not the most helpful comment but probably true, though Barbara is clearly not alone. She has been refereed to an immunologist but the long wait for a local appointment meant that going private has secured an earlier appointment. Hopefully she will find some answers.

People of this generation may also be the first to say, They didnt have allergies in my day! despite the fact that there certainly have been incidences of allergies going back hundreds of years. They were still rare and certainly on the rise and sadly still very little understood.

Celiac Later In Life: Can You Become Gluten Intolerant

Research shows that celiac disease can strike at any age, even in people who have tested negative in the past. Whats behind the rise in celiac among seniors?

Jose L. Pelaez/Corbis

Celiac disease can strike at any age, even in people who once tested negative for the condition.

The digestive disease is being diagnosed more frequently in everyone including the elderly, says Joseph Murray, MD, a gastroenterologist at the Mayo Clinic in Rochester, Minnesota, and author of the book : Essential Guide to Managing Celiac Disease and Other -Related Conditions.

Celiac disease is an autoimmune condition that tends to run in families. People with celiac cant tolerate gluten, a protein found in wheat, barley, and rye, according to the National Institutes of Health . ;In these people, gluten damages the part of the small intestine that helps absorb nutrients. Signs and symptoms may include pain, diarrhea, malnutrition, , and , the NIH says. In older people, cognitive impairment can also be a symptom, Dr. Murray says.

Approach For Cultivation Of Strawberry And Tomato Varieties With Reduced Allergy Potential

Technical University of Munich
Summary:
Strawberries and tomatoes are among the most widely consumed fruits and vegetables worldwide. However, many people are allergic to them, especially if they have been diagnosed with birch pollen allergy. A team has investigated which strawberry or tomato varieties contain fewer allergens than others and to what extent cultivation or preparation methods are involved.

The incidence of food allergies has increased in recent decades: It affects three to four percent of the adult population and five percent of children. Tomatoes and strawberries can cause allergic reactions due to the presence of various allergenic proteins. Of particular note are proteins that resemble the primary allergen in birch pollen and due to this similarity can lead to birch pollen-associated food allergy. About 1.5 percent of the population in Northern Europe and up to 16 percent in Italy are affected by tomato allergies. And around 30 percent of those who are allergic to birch pollen also report allergenic reactions to strawberry fruits.

Symptoms of an immunological reaction to strawberries or tomatoes can affect the skin , irritate mucous membranes and trigger a runny nose, and can also lead to abdominal pain. Food allergy sufferers develop symptoms after eating fresh fruit or vegetables, while processed products are often tolerated.

The specific variety makes all the difference
