Understanding allergies

Do you blow your nose and rub your sore eyes more than usual in the summer? You may have hay fever, also called rhinitis, an allergic reaction that is not related to hay and anything related to smallpox.

Periodically rising in the trees, grass and pollens of grass cause chronic rhinitis — with symptoms of runny nose, sneezing, congestion, runny nose and itchy eyes — in many Americans. And perennial allergic rhinitis affects millions every year thanks to dust, grime and even cockroaches.

So the length of cold that you think you have in January could be hay feversays Christopher Codispoti, MD, Ph.D., specialist in allergy and immunization at Rush University Medical Center.

How do you split the two? Below Codispoti helps to set a straightforward record on the two differences and explain some misconceptions about allergies, which — depending on their severity — can lead to everything from soft skin pains to life-threatening anaphylactic shock.

Allergy vs cold

Cold is a virus, which is contagious. Allergy is not a contagious disease vaccine for the environment; Allergies can not be spread from one person to another. Allergies occur when the immune system overflows into something like pollen or mold (ie allergens) because it confuses it with the virus.

While some symptoms of cold and illness are similar (e.g., runny nose, fatigue, watery eyes), others are not (cold, causing fever and chills). People with the flu recover within a few weeks, while sufferers endure symptoms as long as they are allergic.

No signs, no sweat?

When diagnosing allergies, do not rely on immunoglobulin tests, says Codispoti, which is used by some doctors to diagnose allergic reactions to certain allergens.

Purpose of these blood tests: Our body’s immune system releases immunoglobulins, or bacteria, to detect foreign cells. If the levels of immunologulins of a particular type (immunoglobulin E, IgE) are elevated, then malignancy may be suspected; however, the clinician may want to point out the relationship between IgE levels and clinical signs before identifying them.

Immunoglobulin G (IgG) testing is particularly problematic, according to Codispoti, because the body produces IgG antibodies to respond to many of the foods we eat, not just harmful ones. These IgG dietary supplements represent a previous manifestation; for example, a person may have IgG antibodies to eggs simply because he ate eggs.

Therefore, this test has not been proven to be effective when it comes to identifying allergens for specific foods or environmental factors. But many people with good results go for it thinking that they have to make big lifestyle changes, such as leaving their favorite food or parting with a loved one.

Codispoti Recommendation: If you do not have any food-related symptoms or allergens that you have tested positive — such as rashes, inflammation or abdominal pain — do not change your lifestyle. If you have allergy symptoms but cannot identify the culprit, a skin test is more helpful in determining the root cause.

Spit the dander

Are there really hypoallergenic dogs and cats? While a satisfying thought for many pet lovers, it is not true, Codispoti said. Causes of animal allergens arise from the skin, not the hair. There is no scientific evidence that there is such a thing as a cat or hypoallergenic dog.

“While you can reduce the spread of dander – the shedding skin – by shaving, washing and cleansing, you can’t completely control it,” Codispoti said. “And keeping dogs and cats from licking – either themselves or others – is very difficult,” Codispoti said. “The same goes for cats and dogs.”

He said, sufferers of illness with pets can make changes to improve their appearance, such as limiting where the animals enter their homes. Well, removing the pet from the house will work best, but if this is not an option, keeping the pet out of the bedroom can help reduce your appearance.

Fearless walnut

Gone are the days of pre-secondary school teachers sharing peanut butter cookies. Increasing the number of peanuts, some of which can be life threatening, has completely changed.

But then pregnant women those who do not have peanuts? Will eating peanuts put their babies in danger or will they harm peanuts for the rest of their lives? Will the appearance of the place be able to protect the next generation?

“While judges do not fully understand the impact of peanut butter, the American Academy of Pediatrics states that avoiding peanuts during pregnancy – or during breastfeeding – does not protect a child from developing peanut allergy,” Codispoti said. . “That said, pregnant women with peanut butter should avoid peanut butter for their health.”

Mistake allergies for intolerance

People often blame bloating and other digestive problems for food allergies. But more often than not, says Codispoti, it is actually food intolerance.

What is the difference? Allergies contain responses from your body’s immune system. Allergies occur when exposed to or even detect the amount of allergen and may have symptoms such as rash or hives, which occur immediately after exposure.

Food intolerance, however, has intentional symptoms — such as indigestion — that occur slowly and do not necessarily include immune system. Unlike allergies, the small amount of food in question does not result in an answer.

If you have gastrointestinal problems and are not allergic, other possible causes include lactose intolerance, severe intestinal obstruction and celiac disease.

Many more misunderstandings about allergies persist: For example, malnutrition physical illness-free, and no allergy “in the head” or psychosomatic.

As the number of people suffering from dementia continues to grow, Codispoti hopes our understanding of dementia will increase, and this continued effort to find effective treatments will bring more freedom and less stress to sufferers. ailment.
