What is corn pollen allergy

For mild allergic reactions, treatment generally consists of managing the symptoms alone until the allergic reaction is done.

For anaphylactic reactions, epinephrine (an EpiPen) is the only treatment available, along with immediate medical care in an emergency room.

Anaphylaxis is a life-threatening emergency and immediate medical treatment is needed. Call 911 immediately if you suspect you or a loved one may be having such a reaction.

For some people, spring is a magical time of blooming flowers, longer days, and warmer weather.

For those with seasonal allergies, though, it's more love dark magic, with invisible pollens assaulting your nose, eyes, and face every time you dare to leave your castle (or tiny apartment, as the case may be).

Depending on where you live and what you are allergic to, pollens may start to make you desire to hibernate as early as January until as tardy as early September. “When trees start to get leaves is when tree pollens are out,” says Jacqueline S. Eghrari-Sabet, M.D., spokeswoman for the American College of Allergy, Asthma, and Immunology (ACAAI).

“Grass pollen follows and continues until summer, then ragweed pollen can start as early as summer,” she tells SELF. This is also a time when mold and dust mites can thrive, so if you're also allergic to those, it can be a triple whammy.

Luckily there are remedies—both everyday habits and OTC medications—that can alleviate the sneezing, itchy, watering eyes, congestion, nasal drip, and every those other lovely allergy symptoms that turn you into a red-eyed snot monster. Attempt one or some of the solutions under and see what works best for you.

Because it's far too nice exterior to let allergies hold you cooped up in your apartment.

1. Shut the windows.

If your mom was the type to throw open every window on the first warm day to “air out” the home after winter, don't follow her lead. “The first thing we always tell patients is avoidance—avoid the thing you are allergic to,” Dr. Eghrari-Sabet says. “Opening the windows lets every the pollen in the home, and you need to make [your house] a sanctuary where pollens can't get to you.” Instead, turn on the AC.

2. Use a HEPA filter.

A HEPA filter is better than an ionic air filter, according to the ACAAI. Ionic filters tend to lack the air flow necessary to effectively filter air particles, and they produce ozone, which can be a health risk.

Instead, the ACAAI recommends a HEPA room air cleaner rated with a Clean Air Delivery Rate.

What is corn pollen allergy

Own central air? Use filters with a MERV rating of 11 or 12 and change them every three months.

3. Hold your car windows closed.

Sure, you'll miss that shampoo-commercial-wind-in-your-hair effect. But you'll also miss letting pollens in.

4. Hold your shoes outside.

After running or spending other time exterior, if you can, remove your sneakers and leave them to enjoy the unused air, says Beth Corn, M.D., associate professor of medicine and clinical immunology at Icahn School of Medicine at Mount Sinai. The less you can track inside, the better.

5. Strip down.

Experts tell to change your clothing after coming inside if you can.

“I own patients who bike to work and then they own a change of clothing and change as soon as they get to work,” Dr. Corn says. Certain, you might finish up doing a ton of laundry, but you also won't be sneezing and itching as much. Tradeoff?

6. Send pollen below the drain.

If you can, also shower and wash your hair to really rid your body of the allergens.

7. Sport your shades outside.

Not only will you glance cute and protect your eyes from harmful UV rays, your sunglasses function as a blockade for anything in the air, Dr.

Corn says.

8. Befriend the treadmill.

Walkers and runners, if you suffer from seasonal allergies, why put yourself through the distress of trying to do cardio while sneezing and sniffling? Consider hitting a gym and hopping on a machine, or take this as a chance to stir up your fitness routine and attempt a new class.

9.

What is corn pollen allergy

Or chase the rain.

A excellent rain helps clear pollen from the air, according to the Mayo Clinic, so if Mom Nature's weather aligns with your schedule, go for it.

10. Shift your workout schedule.

One final tip for outdoor exercisers with seasonal allergies: If you can, avoid sweat sessions in the morning, when pollen counts are highest. But don't use this as an excuse. “I'd rather someone exercise than sit on the sofa because it's not the correct pollen time,” Dr. Eghrari-Sabet says.

11. Scrub away mold.

Groan. But hear us out. Although mold is a perennial allergen, it is often worse in spring. “When you get a time when there's a lot of rain, you will get more mold,” Dr.

Eghrari-Sabet says. “And mold can be in the leaves that drop off the trees.” Her solution: Bring out the Clorox and attack any spots you see with some elbow grease.

12. Cover your mattress.

Dust mites are another perennial allergen, and they are worse during times of humidity. “They 'drink' through their skin and they 'drink' the water in the air,” Dr. Eghrari-Sabet explains. She recommends putting a dust mite–proof cover on your mattress because dust mites love to eat skin cells that are on our mattresses. (Eew.)

13.

Spray it away.

If you know when you typically shift from “Yay, spring!” to “Is it winter yet?” because of your allergies, you can head off some distress by using maintenance anti-inflammatory nasal steroids, Eghrari-Sabet says. These include brands such as Flonase, Nasacort, and Rhinocort. “These are meant to be taken ahead of allergy season on a daily basis,” Eghrari-Sabet explains. “They preempt a reaction so you own a better time, but there's no harm in using them after allergy season starts.”

14.

But not with these sprays.

Avoid using any nasal sprays that come with the warning to only use them a few days. Those are not the same thing as the anti-inflammatory nasal sprays, and not only will they not provide the same relief, they can own a rebound effect (meaning, your symptoms get worse after you stop them).

15. Rinse your nose.

Any saline rinse will assist with allergies. (Try this saline rinse recipe that the AAAAI recommends.) “You own pollen up your nose, so this rinses it out, just love taking an shower to get the pollen off your body and hair,” Eghrari-Sabet says.

“Plus, there is a lot of mucus that forms and you desire to get that out [so you can breathe more easily]. You can blow your nose, but you can't get as much gunk out as when you use sinus rinses.” If you also use a nasal spray, Corn says to do the saline rinse first, otherwise it's a moot point. If you use a neti pot for your saline rinse, make certain you use it properly to avoid rare but serious infections.

16. Take an antihistamine.

“Histamine is a chemical the body makes that causes itching, sneezing, and dripping,” Dr. Eghrari-Sabet explains. Ergo, antihistamines assist fight these symptoms. You should only take antihistamines if you own systemic problems, Dr.

Corn says, love a runny nose, postnasal drip, sneezing, or itchy eyes, but not for congestion.

17. Or a decongestant (maybe).

“Predominantly medications that own pseudoephedrine or own 'D' in the name are a decongestant,” Dr. Eghrari-Sabet says. “These work by 'shrink-wrapping' the blood vessels in the nose so you own more room for air. They take swollen blood vessels and squeeze them.” However, be cautious about taking a decongestant.

What is corn pollen allergy

You'll discover they're behind the counter, and the reason is that they hype you up and can elevate your heart rate and blood pressure. So weigh the side effects and your personal health history against the benefits.

18. Do double-duty.

If you've got it all—congestion, sneezing, itching, postnasal drip—a combination antihistamine-decongestant may be best. But again, consider the side effects of the decongestant part of this medication. Talk with your doctor or a pharmacist if you own questions.

19. Go simple on the eyes.

If you can't stop rubbing your eyes (and smudging your makeup) or your peepers glance love you were getting high, start with natural tears products, Dr.

Corn recommends. “Gentle tears or lubricating tears are great,” she says. If that isn't powerful enough, then attempt antihistamine eye drops, available over the counter or with a prescription. If you love a cooling sensation, put the drops in the fridge for more relief. But be careful, contact lens wearers, as these drops can dry your eyes out.

20. Don't attempt essential oils.

Holistic remedies may seem “better” than pills, as scents love ecalyptus and mint are touted as clearing up your nasal passages. But these are actually respiratory irritants, says Dr. Eghrari-Sabet, adding, “You don't desire to smell that up.”

21.

Skip the honey.

There is nothing incorrect with honey on your overnight oatmeal, but don't expect it to assist your allergies. “Honey comes from bees, and bees pollinate flowers. The pollen bees carry is too heavy to be carried by the wind,” Dr. Eghrari-Sabet says. “However, trees and grass [the sources of seasonal allergies] aren't pollinated by bees, so local honey does nothing for you.”

22. If you're allergic to tree pollens, be mindful of fruit.

“The proteins in raw fruit and vegetables are similar to the proteins in pollen.

So if you're allergic to tree pollen, when you take a bite of apples, cherries, pears, et cetera, your body sees it as pollen,” Dr. Corn explains. “And then you get an itchy mouth and throat.” Carrots, peanuts, almonds, and hazelnuts may also cause a reaction. How, if you cook these foods, “the proteins come apart and your body doesn't recognize them as anything dangerous or bothersome,” Dr. Corn adds.

23. If grasses give you grief, watch out for melons.

Peaches, celery, tomatoes, oranges, cantaloupe, watermelon, and honeydew can every cause a reaction for you.

24.

Finally, if ragweed is a drag, these foods might give you issues.

Banana, cucumber, and melon could make a yummy smoothie, but if you're allergic to ragweed, eating these foods may cause a reaction. For a full list of potential food reactions, check out the AAAAI's chart.

25. Discover the cause of your pain.

Dr. Corn encourages everyone to discover out what substances trigger their allergies. “It's such a simple thing to do, to own a skin test,” she says. “It takes a minute, and within 15 minutes you know what you are allergic to.” Then you can be prepared when those pollens rear their ugly heads in your area.

26.

Don't give up.

Dr. Eghrari-Sabet likens allergy shots to a vaccination—it prevents allergic reaction. Each shot contains a little quantity of the allergen, so you gradually decrease your sensitivity to the allergen over time. If you attempt medication and other remedies and are still in dire straights, see an allergist, she says. There are shots for each helpful of pollen, so you can be certain to only get the therapy you need.

With school back in session, there’s so much to ponder about – new classrooms, teachers, and potentially more homework than the year before.

And if your kids own allergies, you own even more to consider than other parents. With a little additional planning, your kids can own a grand school year, without letting allergies disrupt their day.

Dr. Rafiquddin S. Rahimi, of Allergy Relief Clinics in Richardson, Texas, recommends the following back-to-school tips for kids with allergies:


Diagnosis and Testing

Diagnosing food allergies is significant, as the results can own a significant impact on what a person eats each and every day.

That said, the diagnosis of corn allergy can be challenging.

Allergy testing with blood tests and skin tests can be inaccurate, with untrue positive tests occurring often. Such a result, however, does place a person at a higher risk for an allergic reaction to that food and should be considered along with other findings.

A careful history is often the most dependable indicator of a corn allergy, with symptoms of an allergic reaction occurring after eating corn or foods containing corn. The history, however, can be hard to assess for a few reasons:

  1. Corn is present in a vast number of foods and in diverse amounts.
  2. Signs and symptoms are non-specific and may easily be dismissed as a freezing virus, a rash due to irritation, or an allergic reaction due to something else.

With mild symptoms, keeping a food diary is often an excellent start.

This involves recording foods that are eaten, when they are eaten, and any symptoms you experience.

An elimination dietcan also be extremely helpful.

What is corn pollen allergy

With this, the foods that are eaten are greatly restricted, and then individual foods are slowly added back in at specific intervals so that a reaction, if present, can easily be traced back.

The diet often requires a commitment of a minimum of two weeks and often more to identify potential food allergies. If a corn allergy is suspected, a food challenge (eating corn) may be considered, but should only be done under the guidance of an allergist.

Consulting with an allergist who specializes in food allergies early on can be extremely helpful, and is imperative if you own had any symptoms suggestive of an anaphylactic reaction.


Signs and Symptoms

Allergic reactions to corn can take diverse forms.

Common symptoms include:

  1. Hives
  2. Flushing or reddening of the skin
  3. Abdominal pain
  4. Headaches
  5. Hay fever-like symptoms: sneezing, nasal congestion, runny nose
  6. Nausea and/or vomiting
  7. Itching, particularly in or around the mouth (oral allergy syndrome), but may be generalized as well
  8. Wheezing, asthma
  9. Diarrhea

Anaphylaxis may also happen and can include symptoms such as:

  1. Swelling and/or tightness of the lips, tongue, throat, neck, or face
  2. Difficulty breathing
  3. Lethargy, confusion, or loss of consciousness
  4. Rapid heart rate
  5. Hoarse voice
  6. Lightheadedness
  7. A sense of impending doom


Cause

Unlike some other food allergies (nuts, shellfish, and wheat, for example), the exact causes of corn allergy aren't known.

It's thought that a combination of genetic factors, environmental factors, and epigenetic factors (the interaction of genetics and the environment) are at play.

Corn is a cereal grain that contains a protein, zein, which is the suspected culprit in this allergy. A reaction occurs when the body recognizes this protein as foreign and releases immunoglobulin E (IgE), antibodies to attack the protein. IgE then stimulates cells in the immune system to secrete substances such as histamines that are responsible for the symptoms.

Allergic reactions can happen as a result of eating both raw and cooked corn, as well as foods manufactured with corn products.

What is corn pollen allergy

Not every corn products contain zein, but it can be hard to know when it is present, as current food labeling does include a "corn free" designation.

Even coming into contact with surgical gloves or intravenous fluids that contain corn can be problematic. Those who own corn allergy may also react to corn pollen, grass pollen, and cornstarch (typically with hay fever (allergic rhinitis) and/or asthma).

People who own asthma, eczema, hives, hay fever, or other food allergies appear to be at greater risk. A family history of these conditions is also associated with a higher risk, particularly when a sibling has a corn allergy.


Incidence

It's uncertain exactly how common corn allergy is, but some researchers believe it's underdiagnosed.

A 2016 study done in Pakistan found the rate to be 0.86, or almost 1 percent of the population. In the study, a diagnosis of allergy was confirmed by a food challenge.

One study in Honduras of only 50 adults found the prevalence to be 6 percent, but there's currently no excellent estimate of the incidence in the United States. Since corn is present in so numerous products (found in roughly 75 percent of processed foods), minor symptoms could be easily overlooked as due to something else.


Know your child’s allergy triggers and how to manage them.

Nearly 6 million children in the U.S.

own food allergies, and seasonal allergies affect about 40% of school-aged kids. Allergies not only get in the way of learning and concentration during a endless day in the classroom, but they can also lead to emergency situations if your kid and their teachers aren’t careful. Knowing what triggers your child’s allergies and how to manage their symptoms is imperative for keeping your kid comfortable and safe at school.

If you don’t know the exact cause of your children’s allergies, make an appointment with Dr. Rahimi to get them tested as soon as possible.

When you know the triggers and the severity of a potential allergic reaction, you can prepare faculty and the school nurse ahead of time and equip your kid or staff members with necessary medications.

Common food allergy triggers include:

  1. Peanuts
  2. Eggs
  3. Wheat
  4. Milk or other dairy products
  5. Shellfish
  6. Soy

Other allergy triggers commonly include:

  1. Dust
  2. Pet dander
  3. Molds
  4. Tree, plant, and weed pollen
  5. Insect bites

While insect bites may not be as common in the drop as they are in spring and summer months, if your kid is allergic to them, it’s always a excellent thought to remain vigilant any time of year.

Any of these triggers can cause symptoms that make it hard for children to stay focused at school.

Once you understand their triggers, you can create a treatment plan that teachers and school nurses can follow as necessary.

You can also be proactive in keeping triggers away from your children whenever possible. For example, most schools own “peanut-free zones” in the cafeteria, so if your child’s nut allergies are severe, you can make certain they don’t come in contact with nuts, while eating lunch at school.

Or, for example, if your kid is particularly sensitive to ragweed pollen, send an additional set of clothes to school so they can change after outdoor recess.


Know what’s in bloom during drop months

In the drop, the greater Dallas area experiences “weed season” in which ragweed pollen is one of the most predominant allergens your kids face each day on their way to and from school, or anytime they’re outdoors. An abundance of ragweed pollen this time of year can lead to increased asthma symptoms, rhinitis (hay fever), and worsening eczema skin irritations.

Ragweed pollen can also cause conjunctivitis – commonly known as pinkeye.

Additional seasonal allergens that appear in abundance in the Dallas area from September through November, include:

  1. Annual marsh-elder
  2. Great ragweed
  3. Bermuda sagebrush
  4. White sagebrush
  5. Palmer’s amaranth
  6. Corn
  7. Narrow-leaf marsh-elder
  8. Spiny amaranth
  9. Perennial ragweed
  10. Perennial ryegrass

Beyond this list of severe allergens, cedar elm, sugar-berry trees, and alfalfa are among the other culprits that may trigger more moderate allergy symptoms.
