Seasonal allergies are just that; POLLEN allergies that spring up seasonally. Pollen is a fine coarse powder responsible for plant reproduction, and whether it comes from trees, grasses, or weeds, it can cause a variety of symptoms. Some people sneeze, or have a runny nose, others may experience itchy eyes, and a sore throat, and sometimes people will cough, or have clogged ears, hives, fatigue or a headache.Tree pollen causes most spring allergies, which can flare up anywhere from January to May, depending on where you live. And grass pollen causes most late spring and early summer allergies. Grass allergens in Northern and colder climates vary, while Bermuda grass is the main cause in warmer Southern climates. Contact with pollen from these grasses also can result in itching and hives, which is known as contact urticaria. As for late summer and early fall allergies, WEED pollen is typically the main cause. Depending on the area of North America, these weeds include ragweed, sagebrush, pigweed, tumbleweed and cocklebur. Interestingly, pollens that are spread by INSECTS, such as those from brightly colored flowers, don't usually trigger allergy attacks. If you think you have seasonal allergies, you should go see an allergist. A skin or blood test will be able to uncover the cause of your symptoms. And there are many treatments available to ease the symptoms or reduce or prevent the allergic reaction.

One second you're cuddling with your best friend and the next you're feeling lousy because you have a runny nose and itchy eyes. Pet allergies are a big problem for many pet owners. Some knew they were allergic before they brought the pet home. Others developed the allergy months, or even years, after the puppy or kitten came to stay. But what exactly are pet allergies? A pet allergy is a reaction to proteins found in an animal's skin cells, saliva or urine. When cats and dogs lick themselves, their saliva sticks to their hair or fur. Then if they sit or lean against carpets, furniture, bedding and clothing, the saliva, along with skin cells and urine, can be transferred to those surfaces. In addition, as the saliva dries it can become airborne. Plus, outdoor pets have been known to carry pollen and dust, two other common allergens, in their coats, Cats and dogs aren't the only pets that can cause allergies. Mice, gerbils, hamsters, guinea pigs, ferrets and rabbits, who live in cages with cedar or sawdust beddings, can kick up dander, saliva or urine that's mixed in with the chips. And pet birds can trigger allergy attacks since droppings contain bacteria and mold, which some people are allergic to.Whatever the trigger for your pet allergy, once it sets in you will most likely experience sneezing, nasal congestion, a runny nose, and itching of the nose, roof of the mouth and/or throat. You may also have itchy, red or watery eyes, a cough, and facial pressure or pain. But not all pet allergies trigger symptoms related to the nasal passages. Some people with pet allergies develop allergic dermatitis, which causes hives and itching.One interesting feature of pet allergies: They can develop even if you have had a pet for years without any symptoms. This is called becoming SENSITIZED. Or they may be triggered only by animals that are NOT your own. You may develop an immunity to your own pets through long-term exposure and DEsenitization.If you have pet allergies, don't ignore them. When nasal passages are constantly inflamed, they become vulnerable to bacterial infections. And continuous inflammation of the airways can cause difficulty breathing, wheezing and chest tightness culminating in an asthma attack. Talk to an allergist to find effective treatments for your symptoms.For more information on other airborne allergies and how to diagnose or treat them, check out other videos on this site.More »

You've heard of allergies. And you've heard of asthma. But what about allergic ASTHMA? Turns out allergic asthma is actually a combination of the two conditions And it's the most common form of asthma, affecting more than half of all asthma sufferers, including around two and a half million children. An allergy is a hypersensitive response by the immune system to a normally harmless substance, known as an allergen. The immune system triggers the release of histamines that cause reactions ranging from hives or a runny nose to shortness of breath, or in extreme cases, anaphylactic shock. As for asthma, it's an INFLAMMATION of the body's AIRWAYS. During an asthma attack, the muscles surrounding the airways become tight and the lining of the air passages swells. This reduces the amount of air that can come into the lungs, resulting in an asthma attack. ALLERGIC ASTHMA is caused by an allergic reaction to an inhaled substance, such as pollen or mold, which causes histamines to be released, INFLAMMING the airways and INITIATING an asthma attack. The symptoms of allergic asthma include ASTHMA symptoms, such as coughing, shortness of breath and wheezing, AS WELL AS symptoms of an ALLERGY, such as a stuffy or runny nose and excess mucus in the throat. To determine the triggers of your allergic asthma attacks, and to develop a treatment and prevention plan, you should see an asthma specialist regularly. It is important that you follow the prescribed treatments, EVEN IF you are feeling okay. Asthma is a potentially life-threatening condition and should not be ignored. The good news is that treatment can provide effective control.More »

A skin allergy is a hypersensitive response by the immune system to contact with a normally harmless substance, known as an allergen. Allergens may include pollen, dust, animal dander, food proteins, insect venom, or household chemicals. When an allergen comes in contact with skin, antibodies are produced and skin cells release histamines and other chemicals. Theses chemicals trigger inflammation that may result in hives, a rash or contact dermatitis. HIVES are swollen, pale, red bumps, patches, or welts that appear when histamine is released from cells in the skin. Allergic hives can be triggered by FOODS such as nuts, chocolate, fish, and milk; by INSECT STINGS; SUN EXPOSURE, and even by MEDICATIONS such as aspirin and codeine. Hives may last anywhere from a few minutes to a few hours and can be treated with antihistamines or a combination of medications including corticosteroids.ANGIODEMA is a condition that is RELATED to hives, but instead of causing outward bumps, it triggers swelling in the deeper layers of the skin, often around your eyes and lips. Skin allergies are also associated with ECZEMA, also called atopic dermatitis. This is a condition that causes red, flaky patches of skin that, when scratched, can become infected. Although eczema is NOT usually an allergic disorder, it often coexists in people who also have asthma or hay fever. In children, atopic dermatitis has been found to be triggered by food allergies. Experts think it is caused by immune system malfunction and/or highly sensitive skin.CONTACT DERMATITIS is another common skin allergy. While it may look similar to eczema, it's not the same. Contact dermatitis is caused by contact with allergens in cosmetics, perfumes hair dye, metals, topical medications and dental materials. You'll typically spot it on the face, especially the eyelids, neck, hands and feet. It may EVEN appear along the waistline or down the center of the abdomen, due to zippers in clothing. Cold compresses, oatmeal baths, and oral antihistamines are soothing treatments, but if contact dermatitis becomes chronic, it's best to get tested. This way you can pinpoint the main triggers and avoid them, while taking any prescriptions your doctor may recommend. PHOTOSENSITIVITY is one of the RAREST skin allergies. It's caused by an immunological response to sunlight, though fluorescent lighting can set off a reaction, too. The light causes a pink or red rash with blotchy blisters, scaly patches, or raised spots on exposed skin. Itching and burning may occur, sometimes lasting a few days. To treat this rare reaction, doctors usually recommend oral beta-carotene, steroids or other medications.To learn more about allergy triggers, check out other videos on this site.More »

Some of the most common food allergies are milk, eggs, peanuts, soy and wheat. These foods contain allergens that can trigger a number of reactions. Learn more about risk and prevention of food allergies.

Food allergies affect about 4 percent of teens and adults and 5 percent of children. They can be mild or severe depending on the person, and are occasionally fatal. A food allergy occurs when the immune system mistakenly attacks a food protein, thinking it is an invading germ. The severity of symptoms can vary greatly from swelling or hives, to abdominal or digestive issues, respiratory distress, and in rare cases, life-threatening anaphylaxis. While any food is a potential allergen, allergies to these seven foods are more common than others.Peanut allergy affects many children, and can persist into adulthood. The actor Ray Romano and country singer Trace are both still allergic to peanuts. And singer Clay Atkins is allergic to tree nuts, such as walnuts, macadamias and pistachios. Exposure to these allergens can trigger reactions ranging from minor hives to a serious, life-threatening anaphylactic shock.DAIRY proteins such as casein and whey also can cause allergic reactions. And MOLDS, another common allergen, turn up in some aged cheeses. SHELLFISH, including lobster, shrimp and scallops, as wells as squid and octopus, are another common food allergy. It's possible to be allergic to SOME shellfish and not others. Some people can't eat ANY shellfish at all, for risk of anaphylactic shock. WHEAT-or the gluten protein in it-can cause uncomfortable allergic reactions, particularly in the digestive tract. TV host Elizabeth Hasselback and NFL player Drew Brees both have wheat allergies. And wheat and soy allergies often go hand in hand. Research has found that those who are allergic to soy proteins are usually also allergic to wheat. This is distinct from celiac disease which is an autoimmune disorder. EGG WHITES are a common allergy in young and old alike. And..Both FRUITS and VEGETABLES turn out to be allergy triggers for some people. In fact, fruit allergies make up about 10 percent of all food-related allergies. Celery, especially the root, can cause anaphylactic shock. Pollens found on apples and naturally occurring salicylates found in numerous vegetables can set off attacks. And corn, which is found in practically everything from sweeteners to milk shakes, is another source of problems.Fortunately, reactions to fruit and vegetable allergies are usually mild and often just affect the mouth, causing itching, a rash, or blisters where the food touches the lips and mouth.If you have food allergies, read food labels CAREFULLY. The FDA requires food manufacturers to list ingredients that trigger food allergies and alert consumers to their potential presence in prepared and packaged foods..

Keeping a tidy home can be a task, but it becomes a feat if you have indoor allergies to common household "pests," such as dust, mold or pet dander. The most common indoor allergen is the nearly invisible DUST MITE, which feeds off dead skin cells. When dust mite residue is inhaled, the immune system may start a cascade of reactions that leads to the release of histamines. These histamines cause the eyes to itch, the nose to run and the airways to tighten, resulting in coughing and shortness of breath. MOLD, often found in the kitchen, bathroom and basement, can grow beneath wallpaper, in rugs and on the soil of houseplants. When mold spores are released into the air, we may inhale them, which can cause coughing, sneezing and itching eyes, as well as hives and scaly rashes in some people. Pet dander, and saliva and urine attached to pet hair or fur, are also common indoor allergens. About 6 percent of the population is allergic to cats, followed closely by dogs and then rodents like gerbils, ferrets and mice. And a surprising allergen? Cockroaches. Recent research suggests that cockroaches, specifically their digestive enzymes, saliva, and body parts, can be a major factor in both asthma and nasal allergies. If you think you have indoor allergies, talk with your doctor or an allergist about the best way to identify the cause of your symptoms and your treatment options.More »

What do farmers loggers, wine makers and people with pet and pollen allergies have in common? They're all at high risk for developing mold allergies. Mold grows in damp places, such as soil, basements, bathrooms and kitchens. And when spores are released into the air, they can find their way into your nasal passages and airways. In people with sensitive immune systems, this starts a cascade of reactions that culminates in the release of histamines and other chemicals from cells in the lining of the nose, sinuses, eyes, throat and or lungs. The result is sneezing, itching, nasal discharge, congestion and sometimes asthma or a dry, scaly rash. These symptoms can flare up in the summer, when outdoor molds are at their highest, or linger throughout the year as indoor molds thrive. Mold can also be found in food, which may explain why some people are allergic to mushrooms, aged cheeses or smoked meats. Even breads and other food made with yeast can cause an allergic reaction. So... if a slice of mushroom pizza or day of gardening has left you sneezing and itching, it's possible you may have a mold allergy. A simple skin test can determine if you do. The treatment may include over-the-counter antihistamines and decongestants. Or your doctor may prescribe corticosteroid nasal sprays. And if that isn't doing the trick, there are always allergy shots.To ease symptoms, try wearing a dust mask when cleaning or gardening. Reduce indoor humidity to prevent mold from growing, Clean all garbage cans frequently, Repair leaks right away, and Recycle old books and newspapers before spores build up.

You may think you're allergic to dust, but for most people it's actually a microscopic insect, known as a DUST MITE. Dust mites live IN the dust and ON your bedding and furniture. THEY are what cause the sneezing and watery eyes, asthma and even eczema. Dust mites, discovered in 1964, are tiny members of the spider family, about a third of a millimeter in length. Fortunately, dust mites don't bite, spread disease, or live on humans. But they DO eat skin - dead skin -and their waste is what causes allergic reactions. According to researchers, the mite can live for up to 30 days and drops about 20 fecal pellets per day. So just think of how many pellets are kicked up into the air while vacuuming, bed making, or just walking along a carpet.Dust mites nestle into mattresses, sheets and blankets, feather pillows and stuffed animals that collect our sloughed off skin cells and secretions. They also thrive anywhere that the humidity is above 55 percent, making most coastal areas ideal habitats.About 10 percent of the population is allergic to dust mites. If that includes you or someone in your family, you can limit exposure by: Wrapping mattresses, box springs, and pillows with mite-proof covers, Swapping upholstered furniture for wooden, leather, or vinyl, Using a vacuum cleaner with a HEPA filter, And keeping stuffed toys washed, and off the beds.

Over two million people in the United States suffer from a bee sting allergy. Symptoms of this allergy range from itching to anaphylaxis and dizziness. Watch this video for more.
Transcript: Insects alone are annoying enough. Now imagine being ALLERGIC to them! More than 2 million Americans...
Insects alone are annoying enough. Now imagine being ALLERGIC to them! More than 2 million Americans ARE allergic to insect stings and bites from bees, wasps, fire ants, mosquitoes and scorpions. SOMETIMES these allergies can prove deadly. Stinging insects inject a venom into the body, while BITING insects introduce anti-coagulants. BOTH substances can trigger an immune system response that produces a WIDE range of allergy symptoms. For instance, some people may react with minor swelling or itching, while others can have a full body reaction including HIVES, flushed skin, tingling of the mouth, nausea and vomiting. Additional symptoms of insect allergies can include blistering rashes, bruises, or large areas of swelling. Sometimes these reactions occur suddenly; other times it can take up to 24 hours. LESS common, but incredibly serious, are those who react with an anaphylactic response to an insect sting, like Macaulay Culkin's character did in the movie "My Girl" These rare, but severe, reactions to insect stings or bites cause the airways to swell and blood pressure drastically drops, risking either asphyxiation or cardiac arrest. People prone to this type of severe response ARE at risk of death from a simple bee sting, and will typically carry an epinephrine injection - or Epi-Pen - with them at all times. They should head to a doctor or emergency room RIGHT AFTER any use. Researchers have found that it usually takes at least ONE sting or bite with NO reaction, before an allergy can develop. Which means, even if you ARE allergic, it's rare that you'll react on the first bite.If an insect sting DOES rile up your immune system, you'll be 60 times more likely to have a noticeable allergic reaction after your SECOND exposure to the bite or sting. Treatment for mild allergic reactions to bites and stings includes using a topical anti-histamine cream and an icepack. But if the itching persists, and hives develop, you may want to grab an oral antihistamine and give your doctor a call, just as a precaution.

Anaphylactic reactions are extremely rare and can be life threatening. These can cause tongue swelling, hives, and shock. Check out the video to learn some interesting facts.
Transcript: It's rare, but allergies CAN be deadly. Anaphylaxis, a severe WHOLE-BODY reaction can lead to suffocation...
It's rare, but allergies CAN be deadly. Anaphylaxis, a severe WHOLE-BODY reaction can lead to suffocation or heart failure. According to research, anaphylactic reactions are responsible for approximately 1,500 deaths in the U.S. each year. And 88 percent of those involve sudden cardiovascular collapse. Anaphylaxis typically occurs after a SECOND exposure to an allergen,. This is because the FIRST exposure causes the immune system to create antibodies to the TRIGGERING SUBSTANCE-think peanuts, bee stings, or mold. The second exposure sends those antibodies into action, causing a cascade of bodily reactions that lead to loss of blood pressure, hives, constriction of airways, and gastrointestional problems. The skin and respiratory system are most likely to be affected, followed by the gastrointestinal tract and circulatory and nervous systems. The most COMMON triggers of anaphylaxis are FOODS such as peanuts, wheat, tree nuts, shellfish, fish, milk, and eggs, MEDICATIONS, including antibiotics, aspirin, ibuprofen, and other anti-inflammatory drugs, as well as insect VENOM from stings have also been known to trigger an anaphylactic reaction. If you are HIGHLY allergic to ANY substance, and have experienced an anaphylactic reaction, OR if you are at risk due to genetics or past health history, you should have an "allergy action plan." Carry an epinephrine injection with you at all times; Wear a medic alert bracelet that explains your potential condition, and in a crisis Call 911 immediately. EMTs may give antihistamines and corticosteroids intravenously to reduce airway inflammation and a beta agonist to relieve breathing symptoms.

If you’re experiencing burning of eyes, itching, redness, and watering, there is a high probability that you have eye allergies. Learn about its causes and prevention through this video.
Transcript: 27 million Americans, that's about 10 percent of the population, have eye allergies, also called allergic...
27 million Americans, that's about 10 percent of the population, have eye allergies, also called allergic conjunctivitis. This form of allergy can happen when the cells in the mucus lining of the eyes--called the CONJUNCTIVA--come in contact with AIRBORNE allergens, such as grass, tree and weed POLLEN or mold spores. People who are sensitive to these allergens can develop SEASONAL allergic conjunctivitis, the most common type of eye allergy. TOPICAL products that are applied around the eyes can also trigger an eye allergy. Cosmetics, such as eye shadow, eye pencils and mascara may cause blisters, itching, and redness, especially if they contain certain dyes or traces of metals. Whether the trigger is airborne or topical, in sensitive people, exposure to these allergens can cause the cells in the conjunctiva to release histamines and other chemicals. The result? Itchy, red, watery eyes.Very often such eye irritation coexists with NASAL allergy symptoms, such as sneezing, sniffling and a stuffy nose. This one-two punch is called allergic RHINOconjunctivitis. You can get relief with oral antihistamines and or antihistamine eye drops, and by avoiding rubbing your eyes, which can increase the irritation.Contact lenses may also cause eye allergies. People who wear hard or extended-wear contact lenses may become allergic to the proteins that can build up on a lens. In extreme cases, the crystallized goop on the lens can cause red bumps and thick discharge on the conjunctiva under the upper eyelid. This is called giant papillary conjunctivitis. There is one more form of eye allergy that is rare but serious. Atopic keratoconjunctivitis (AKC) is the result of a genetic condition that causes the immune system to produce higher than normal antibodies in response to an allergen. This usually appears in adolescents and affects males more than females. This condition makes the conjunctiva red and swollen and, if untreated, it can cause ulceration, scarring, cataracts, and cornea damage.

If you're sniffling, sneezing and feeling out of sorts every spring and fall, it COULD be a sign of SEASONAL allergies. Allergies CAN be controlled and treated, so if you have any of these symptoms for more than a WEEK, you should see you doctor.Five common symptoms of seasonal allergies are: An itchy nose that's running one second and congested the next. If you are allergic, when you breathe in pollen or other seasonal allergens your immune system reacts and your cells release inflammatory histamines. Their job is to flush away the allergen, but they also cause nasal congestion and excess mucus production. Red, watery, itchy eyes. Allergens can cause the thin membrane protecting the eye to become inflamed. When that happens, the eyes can become sore, watery and itchy. A scratchy, tight throat. Inhaling pollen or mold spores can bring on an allergic response in the throat and airways, making your throat sore and causing wheezing. THIS SYMPTOM is also triggered by the release of histamines. Hives If you are allergic to pollen and it comes in contact with your skin, you can develop contact dermatitis-or hives. To avoid exposure, stay indoors between 5 and 10 am on high pollen days. ...and Headache. Seasonal allergies inflame the nose and sinuses which can trigger a headache. Decongestants can ease the pressure.To find out how to diagnose and treat certain allergies, check out other videos on this site.More »
