Everything About Allergy

People who fear seasonal allergies may find some relief that researchers have actually found the triggering mechanism, or the on/off switch that triggers allergies in the lab and may soon be on the hunt for similar mechanisms in humans. Seasonal allergies affect a lot of people the world over and is considered to be a billion dollar industry for those who make and develop cures to relieve those runny noses. The study has also found that the human body has a proper balance that is upset by these allergens, but should also be capable of doing the balancing act on its own without medication. The researchers are now looking at the possibility of specific genes that may be damaged ths resulting in the inability of the immune system to cope and maintain the balance which we often rely upon for the rest of the year. Time will tell if similar mechanisms and the specific cure for these abnormalities may eventually lead to more effective cures for the millions who suffer, sneeze and get runny noses each and every spring, for a better tomorrow.

Everybody knows that smoking can eventually kill you but new research is saying that smoke form these deadly things can indeed prevent some allergies. The study shows that the smoke form cigarettes actually lessens the response of immune cells to specific types of allergies. The surprising thing is that smokers are apparently getting some improvement in the way their bodies react to several allergens, either softening the blow or halting adverse reactions all together. This all sounds crazy but the ground-braking research shows that smokers have a slightly varied way of reacting to allergens compared to normal non-smokers who react to the slightest presence of these nasty substances. But don’t go grabbing a pack for it does cause lung cancer and even with lessened reactivity to specific allergens, it may actually shorten your life by a lot of years.

Rhinitis is associated with allergens in the air and is considered to be more of a seasonal illness by most. The surprising part is that allergic rhinitis is known to cause death if it is compounded by obstructed nasal passages which may explain the disassociation of the allergy to snoring or daytime sleepiness. The presence of a blockage in the nasal cavities tends to aggravate the effects of the rhinitis causing blockage of the pathway effectively suffocating people in their sleep. These blockages are also responsible for other symptoms such as headaches, thirst, disturbed sleep, sleepiness during the day and more, all of which can cause serious social disruption enough to make behavior unpredictable.

Scientists have discovered that a specific compound chmokine eotaxin, to be responsible in the over-reaction of the human body to infections. This compound is the chemical marker that prevents our immune system’s security guards that detects invaders and then directs killer cells to the site to effect an attack to defend us. Exposure to eotaxin tends to block the ability of patrolling attack cells from becoming seekers that finds these invaders thus causing the system to go haywire. The jumble of cellular response triggers a confusing to the body’s immune systems that a violent mass production of killer cells ensues in what can be called a panic attack as it knows there are invaders for the normal defenses aren’t really working but they are not getting anything done.

Anaphylactic shock (anaphylaxis) is one of the most life-threatening severe allergic reactions. Allergies may be caused by an ingestion (peanuts), skin contact (pollen), injection, or inhalation of an allergen.

Sensitization to a particular substance is required for an anaphylactic reaction to occur. An example is when a person is stung by a bee for a first time (sensitizing dose), anapahylaxis may not occur. Succeeding bee stings (shocking dose) in the future will have a sudden, severe allergic reaction to the person.

Anaphylaxis involves the whole body. A person experiencing anaphylactic shock will experience difficulty in breathing, shock, polyuria, urticaria (hives), vomiting, flushed appearance, swelling of the lips, face, neck and throat, and could even progress to death.

Due to its life-threatening nature, risks of brain and organ damage (death) are imminent if emergency medical intervention is not given. Epinephrine (adrenaline) is the primary treatment for cases of anaphylactic reaction.

Talk about unexpected relationships, the results of the study have been so dumbfounding, for though allergies are a nuisance, they can help fight some forms of cancer, researchers are saying. Allergic symptoms such as sneezing, tearing, coughing and itching can in fact lower risks for developing cancer in the colon, skin, bladder, mouth, throat, cervix and the uterus that may be affected by environmental factors. Tissues exposed to, say, high levels of pollution such as the mouth, skin and throat may find the toxins expelled by allergic reactions enough to prevent the mutation of the cells and becoming cancerous. Food allergies may also prevent such cancers from ever starting which goes to show, that a sniffle may indeed be a blessing in disguise or it may be the body simply irritated and reacting as needed. So next time you have the flu, be grateful for it might just be your body disposing of cancer causing agents that you may have come in contact with. So having an allergy may not be a curse after all, but a blessing in disguise.

Do you know that allergies and the medication that people consume to tame them are worth an estimated $18 billion Dollars. Over 50 million Americans alone suffer from the disease and global figures are mind-boggling. The term allergy actually denotes a drastic reaction by the human body to known allergens such as pollen, dust, food and many other irritants that causes reactions within the body. The gene that makes one person highly reactive to one allergen may actually not affect the next person which is due to the individual characteristics of the human body and the differences in the way we react to them. Nobody is immune for even a child can be born allergic of all things milk, to the elderly who got welts as an allergic reaction to new medication. The best defense is to steer away from these allergens but some being seasonal, the only way to deal with them is to take medication that does not actually cure the disease but tames the allergic reaction making it more bearable.

Dust, cats, peanuts, cockroaches. An odd grouping, but one with a common thread: allergies — a major cause of illness in the United States. Up to 50 million Americans, including millions of kids, have some type of allergy. In fact, allergies account for the loss of an estimated 2 million schooldays per year.

What Are Allergies?
An allergy is an overreaction of the immune system to a substance that’s harmless to most people. But in someone with an allergy, the body’s immune system treats the substance (called an allergen) as an invader and reacts inappropriately, resulting in symptoms that can be anywhere from annoying to possibly harmful to the person.

In an attempt to protect the body, the immune system of the allergic person produces antibodies called immunoglobulin E (IgE). Those antibodies then cause mast cells (allergy cells in the body) to release chemicals, including histamine, into the bloodstream to defend against the allergen “invader.”

Egg allergy usually occur in children, and is eventually outgrown. But a small percentage remain allergic, and avoidance of foods, and even other non-food products, that contain egg is the best option, especially for those who manifest dangerous symptoms. For those whose symptoms are tolerable, like rashes, they are able to take in a little amount of products containing egg.

The current flu vaccines are developed using eggs, and allergic patients may react to the shot. If a patient cannot tolerate the vaccine, the family members should have a flu shot to decrease the person’s probability of having the flu.
