However, changing a mother’s diet during pregnancy or while breast-feeding does not seem to help prevent allergy-related conditions.

For most children, changing diet or special formulas does not seem to prevent these problems. If there is a family history of eczema and allergies in a parent, brother, or sister, discuss the infant feeding with your child’s doctor. The timing of introduction of solid foods in general, as well as use of several specific foods, can help prevent some allergies.

There is also evidence that infants exposed to certain airborne allergens (such as dust mites and cat dander) may be less likely to develop related allergies. This is called the “hygiene hypothesis” and sprang from observations that infants on farms tend to have fewer allergies than those who grow up in environments that are more sterile.

Once allergies have developed, treating the allergies and carefully avoiding those things that cause reactions can prevent allergies in the future.

The best prevention is to remove the potential allergen that triggers an allergy whether it is from you home or work. Even you could minimize the level of the offending allergen, your allergy symptoms and medication requirement may be reduced. The following suggestion may help you to reduce allergens around you:
1.Keep you home dry and well ventilated

2.Cut down on dust around you living area by cleaning regularly

3.If you suffer dust allergy it would be most beneficial by buying barrier cover for you bedding. These are especially designed to prevent dust mites and their droppings for escaping.

4.For people who suffer for pet allergy (such as dog allergy or cat allergy) the first priority is to remove these pet always from your home. If it is too traumatic then you try to keep the outside in your yard as much as possible. Try not to allow your pet in your living area and bath them at least once every two weeks.

5.If you suffer from skin allergy it is suggested that you try this two parts to breaking this so-called itch-scratch-itch cycle and preventing allergic skin rashes by applying moisturizers as dry skin will cause cracked and inflamed skin. This would further stimulate your immune system to develop a rash. On the other hand, by taking antihistamines can treat the symptoms of the rash and prevent it for getting worse.

6.To prevent food allergy (such as gluten allergy or wheat allergy) try to avoid food that contains ingredients that causes you to have an attack. When you purchase your foods from the supermarket check out the ingredient label for any ingredient that you are allergic to. Also when eating out at restaurants, when ordering your food at a specific questions regarding ingredients in there marinade or sauces.

7.Medication allergies can get you mild to severe side effects. Therefore, the best prevent is to clarify and make sure you inform any allergy to medication to your health-care provider. Many people with allergies to multiple antibiotics keep a list of what medications they can take safely.

8.If you previously have had an allergic reaction to insect bites, the best prevention is to remove all hornet’s nests or beehives for your yard and the eaves of your home. If you happen to get stung or bitten, the best preventive is to take an antihistamine immediately to help to minimize reactions such as rashes, swelling or itchiness. If there is no sign to improvement or the reaction become worst contact you healthcare provider or call you local emergency for assistant.

After completing medical school and graduating with a medical degree, a physician will then undergo three years of training in internal medicine (to become an internist) or pediatrics (to become a pediatrician). Once physicians have finished training in one of these specialties, they must pass the exam of either the American Board of Pediatrics (ABP) or the American Board of Internal Medicine (ABIM). Internists or pediatricians who wish to focus on the sub-specialty of allergy-immunology then complete at least an additional two years of study, called a fellowship, in an allergy/immunology training program. Allergist/immunologists who are listed as ABAI-certified have successfully passed the certifying examination of the American Board of Allergy and Immunology (ABAI), following their fellowship.

In the United Kingdom, allergy is a subspecialty of general medicine or pediatrics. After obtaining postgraduate exams (MRCP or MRCPCH respectively) a doctor works for several years as a specialist registrar before qualifying for the General Medical Council specialist register. Allergy services may also be delivered by immunologists. A 2003 Royal College of Physicians report presented a case for improvement of what were felt to be inadequate allergy services in the UK. In 2006, the House of Lords convened a subcommittee that reported in 2007. It concluded likewise that allergy services were insufficient to deal with what the Lords referred to as an “allergy epidemic” and its social cost; it made several other recommendations.

Discover the truth about allergy medication, including oral antihistamines, nasal antihistamines, decongestants, and nasal sprays…

allergy medication is widely prescribed all over the world. While some of these medicines are available by prescription, there are many available over-the-counter. If you watch television or read magazines, you have probably seen some of the numerous ads for allergy related medication, since these products are often marketed toward the consumer directly.

In recent years there has been a great increase in the types of medicines available for those with allergies, as well as an increase in the number of allergy sufferers who take prescription medication. Currently, about 50% of those with allergies take prescription medication and 35% of those with allergies take over-the-counter medicine for relief. There is room for improvement, however. 65% of allergy doctors and physicians were only partially satisfied with the allergy medication available and more than half of allergists surveyed were prescribing more than one medication for their patients.

Traditional treatment and management of allergies consisted simply of avoiding the allergen in question or otherwise reducing exposure. For instance, people with cat allergies were encouraged to avoid them. However, while avoidance of allergens may reduce symptoms and avoid life-threatening anaphylaxis, it is difficult to achieve for those with pollen or similar air-borne allergies. Nonetheless, strict avoidance of allergens is still considered a useful treatment method, and is often used in managing food allergies.

Several antagonistic drugs are used to block the action of allergic mediators, or to prevent activation of cells and degranulation processes. These include antihistamines, glucocorticoids, epinephrine (adrenaline), theophylline and cromolyn sodium. Anti-leukotrienes, such as Montelukast (Singulair) or Zafirlukast (Accolate), are FDA approved for treatment of allergic diseases. Anti-cholinergics, decongestants, mast cell stabilizers, and other compounds thought to impair eosinophil chemotaxis, are also commonly used. These drugs help to alleviate the symptoms of allergy, and are imperative in the recovery of acute anaphylaxis, but play little role in chronic treatment of allergic disorders.

Desensitization or hyposensitization is a treatment in which the patient is gradually vaccinated with progressively larger doses of the allergen in question. This can either reduce the severity or eliminate hypersensitivity altogether. It relies on the progressive skewing of IgG antibody production, to block excessive IgE production seen in atopys. In a sense, the person builds up immunity to increasing amounts of the allergen in question. Studies have demonstrated the long-term efficacy and the preventive effect of immunotherapy in reducing the development of new allergy. Meta-analyses have also confirmed efficacy of the treatment in allergic rhinitis in children and in asthma. A review by the Mayo Clinic in Rochester confirmed the safety and efficacy of allergen immunotherapy for allergic rhinitis and conjunctivitis, allergic forms of asthma, and stinging insect based on numerous well-designed scientific studies. Additionally, national and international guidelines confirm the clinical efficacy of injection immunotherapy in rhinitis and asthma, as well as the safety, provided that recommendations are followed.

A second form of immunotherapy involves the intravenous injection of monoclonal anti-IgE antibodies. These bind to free and B-cell associated IgE; signalling their destruction. They do not bind to IgE already bound to the Fc receptor on basophils and mast cells, as this would stimulate the allergic inflammatory response. The first agent of this class is Omalizumab. While this form of immunotherapy is very effective in treating several types of atopy, it should not be used in treating the majority of people with food allergies.

A third type, Sublingual immunotherapy, is an orally-administered therapy which takes advantage of oral immune tolerance to non-pathogenic antigens such as foods and resident bacteria. This therapy currently accounts for 40 percent of allergy treatment in Europe.[citation needed] In the United States, sublingual immunotherapy is gaining support among traditional allergists and is endorsed by doctors who treat allergy.

Allergy shot treatment is the closest thing to a ‘cure’ for allergic symptoms. This therapy requires a long-term commitment.

Severe allergic reactions (anaphylaxis) require treatment with a medicine called epinephrine, which can be life saving when immediately given.

The best way to reduce symptoms is to try and avoid what causes your allergies in the first place. This is especially important for food and drug allergies.

There are several types of medications available to prevent and treat allergies. Which medicine your doctor recommends depends on the type and severity of your symptoms, your age, and overall health.

Specific illnesses that are caused by allergies (such as asthma, hay fever, and eczema) may require other treatments.

Medications that can be used to treat allergies include:

ANTIHISTAMINES

Antihistamines are available over-the-counter and by prescription. They are available in many forms, including:

1.Nasal spray

2.Liquid

3.Injection

4.Eye drops

5.Capsules and pills

CORTICOSTEROIDS

Anti-inflammatory medications (corticosteroids) are available in many forms, including:

1.Lung inhaler

2.Nasal spray

3.Lung inhaler

4.Creams and ointment for the skin

Patients with severe allergic symptoms may be prescribed corticosteroid pills or injections for short periods of time.

DECONGESTANTS

Decongestants can help relieve a stuffy nose. Decongestant nasal spray should not be used for more than several days, because they can cause a “rebound” effect and make the congestion worse. Decongestants in pill form do not cause this problem.

OTHER MEDICINES

Leukotriene inhibitors are medicines that specifically block the substances that trigger allergies. Zafirlukast (Accolate) and montelukast (Singulair) are approved for those with asthma and indoor and outdoor allergies.

ALLERGY SHOTS

Allergy shots (immunotherapy) are occasionally recommended if the allergen cannot be avoided and symptoms are hard to control. Allergy shots keep your body from over-reacting to the allergen. Regular injections of the allergen are given, with each dose slightly larger than the previous dose until a maximum dose is reached. They do not work for everybody and require frequent doctor’s visits.

An experimental treatment, enzyme potentiated desensitization (EPD), has been tried for decades but is not generally accepted as effective. EPD uses dilutions of allergen and an enzyme, beta-glucuronidase, to which T-regulatory lymphocytes are supposed to respond by favouring desensitization, or down-regulation, rather than sensitization. EPD has also been tried for the treatment of autoimmune diseases but again is not approved by the U.S. Food and Drug Administration or of proven effectiveness.

In alternative medicine, a number of allergy treatments are described by its practitioners, particularly naturopathic, herbal medicine, homeopathy, traditional Chinese medicine, and applied kinesiology. Systematic literature searches conducted by the Mayo Clinic through 2006, involving hundreds of articles studying multiple conditions, including asthma and upper respiratory tract infection showed no effectiveness of homeopathic treatments, and no difference compared with placebo. The authors concluded that, based on rigorous clinical trials of all types of homeopathy for childhood and adolescence ailments, there is no convincing evidence that supports the use of homeopathic treatments.

Allergy testing may be needed to determine if the symptoms are an actual allergy or caused by other problems. For example, eating contaminated food (food poisoning) may cause symptoms similar to food allergies. Some medications (such as aspirin and ampicillin) can produce non-allergic reactions, including rashes. A runny nose or cough may actually be due to an infection.

Skin testing is the most common method of allergy testing. One type of skin testing is the prick test. It involves placing a small amount of the suspected allergy-causing substances on the skin, and then slightly pricking the area so the substance moves under the skin. The skin is closely watched for signs of a reaction, which include swelling and redness. Skin testing may be an option for some young children and infants.

Other types of skin tests include patch testing and intradermal testing. For detailed information, see:Allergy testing

Blood tests can measure the levels of specific allergy-related substances, especially one called immunoglobulin E (IgE).

A complete blood count (CBC), specifically the eosinophil white blood cell count, may also help reveal allergies.

In some cases, the doctor may tell you to avoid certain items to see if you get better, or to use suspected items to see if you feel worse. This is called “use or elimination testing.” This is often used to check for food or medication allergies.

The doctor may also check your reaction to physical triggers by apply heat, cold, or other stimulation to your body and watching for an allergic response.

Sometimes, a suspected allergen is dissolved and dropped into the lower eyelid to check for an allergic reaction. This should only be done by a health care provider.

For assessing the presence of allergen-specific IgE antibodies, allergy skin testing is preferred over blood allergy tests because it is more sensitive and specific, simpler to use, and less expensive. Skin testing is also known as “puncture testing” and “prick testing” due to the series of tiny puncture or pricks made into the patient’s skin. Small amounts of suspected allergens and/or their extracts (pollen, grass, mite proteins, peanut extract, etc.) are introduced to sites on the skin marked with pen or dye (the ink/dye should be carefully selected, lest it cause an allergic response itself). A small plastic or metal device is used to puncture or prick the skin. Sometimes, the allergens are injected “intradermally” into the patient’s skin, with a needle and syringe. Common areas for testing include the inside forearm and the back. If the patient is allergic to the substance, then a visible inflammatory reaction will usually occur within 30 minutes. This response will range from slight reddening of the skin to a full-blown hive (called “wheal and flare”) in more sensitive patients. Interpretation of the results of the skin prick test is normally done by allergists on a scale of severity, with +/- meaning borderline reactivity, and 4+ being a large reaction. Increasingly, allergists are measuring and recording the diameter of the wheal and flare reaction. Interpretation by well-trained allergists is often guided by relevant literature. Some patients may believe they have determined their own allergic sensitivity from observation, but a skin test has been shown to be much better than patient observation to detect allergy.

If a serious life threatening anaphylactic reaction has brought a patient in for evaluation, some allergists will prefer an initial blood test prior to performing the skin prick test. Skin tests may not be an option if the patient has widespread skin disease or has taken antihistamines sometime the last several days.

Aside from these ambient allergens, allergic reactions can result from foods, insect stings, and reactions to medications like aspirin and antibiotics such as penicillin. Symptoms of food allergy include abdominal pain, bloating, vomiting, diarrhea, itchy skin, and swelling of the skin during hives. Food allergies rarely cause respiratory (asthmatic) reactions, or rhinitis. Insect stings, antibiotics, and certain medicines produce a systemic allergic response that is also called anaphylaxis; multiple organ systems can be affected, including the digestive system, the respiratory system, and the circulatory system. Depending of the rate of severity, it can cause cutaneous reactions, bronchoconstriction, edema, hypotension, coma, and even death. This type of reaction can be triggered suddenly, or the onset can be delayed. The severity of this type of allergic response often requires injections of epinephrine, sometimes through a device known as the EpiPen or Twinject auto-injector. The nature of anaphylaxis is such that the reaction can seem to be subsiding, but may recur throughout a prolonged period of time.

Substances that come into contact with the skin, such as latex, are also common causes of allergic reactions, known as contact dermatitis or eczema.Skin allergies frequently cause rashes, or swelling and inflammation within the skin, in what is known as a “wheal and flare” reaction characteristic of hives and angioedema.

Symptoms

1. Breathing problems

2. Burning, tearing, or itchy eyes

3. Conjunctivitis (red, swollen eyes)

4. Coughing

5. Diarrhea

6. Headache

7. Hives

8. Itching of the nose, mouth, throat, skin, or any other area

9. Runny nose

10. Skin rashes

11. Stomach cramps

12. Vomiting

13. Wheezing

What part of the body is contacted by the allergen plays a role in the symptoms you develop. For example:

1.Allergens that are breathed in often cause a stuffy nose, itchy nose and throat, mucus production, cough, or wheezing

2.Allergens that touch the eyes may cause itchy, watery, red, swollen eyes.

3.Eating something you are allergic to can cause nausea, vomiting, abdominal pain, cramping, diarrhea, or a severe, life-threatening reaction

4.Allergens that touch the skin can cause a skin rash, hives, itching, blisters, or even skin peeling

5. Drug allergies usually involve the whole body and can lead to a variety of symptoms

The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Although the various allergic diseases may appear different, they all result from an exaggerated immune response to foreign substances in sensitive people. The following brief descriptions will serve as an overview of common allergic disorders.

One of the most common food allergies is a sensitivity to peanuts. Peanut allergies may be extremely severe, but can sometimes be outgrown by children school-age. Tree nuts, including pecans, pistachios, pine nuts, and walnuts, are another common allergen. Sufferers may be sensitive to one, or many, tree nuts.Also seeds, including sesame seeds and poppy seeds, contain oils where protein is present, which may elicit an allergic reaction.

Egg allergies affect about one in fifty children but are frequently outgrown by children when they reach age five.Typically the sensitivity is to proteins in the yolk, rather than the white.

Milk, from cows, goats or sheep, is another common allergy-causing food, and many sufferers are also unable to tolerate dairy products such as cheese. A small portion of children with a milk allergy, roughly ten percent, will have a reaction to beef. Beef contains a small amount of protein that is present in cow’s milk.

Other foods containing allergenic proteins include soy, wheat, fish, shellfish, fruits, vegetables, spices, synthetic and natural colors, and chemical additives.

About 40% of us suffer from some form of allergies. And they’re particularly bad during spring and fall, when pollens and molds are high. But allergies aren’t just about a runny nose and scratchy throat. In fact, allergies are caused by a reaction in your immune system. Read more about it in our Allergy Care Center. 3

In simple terms, an allergy is a hyperactive response of the immune system to certain substances which are “foreign” to our bodies. These substances are called “allergens”, and they can range from food and pollen to dust and drugs. Allergies are something we acquire throughout life, and some people are more susceptible than others.

Conventional treatment of allergies is most commonly directed at blocking the immune response, or in more severe cases, at suppressing the entire immune function with steroids, both systemic and topical. While this approach can provide symptomatic relief, it does nothing to address the
underlying cause of the problem. Patients often become dependant on their medication, they suffer from numerous side effects, and more importantly, they worsen their overall health by constantly suppressing their immune system.

In October 2002, the U.S. Food and Drug Administration (FDA) reported that Pfizer’s blockbuster antihistamine frug “Zyrtec” had gained a supplemental U.S. approval for use in children as young as 6 months old. Zyrtec (cetirizine hydrochloride), which is currently indicated to relieve symptoms of allergic rhinitis – nasal inflammation – and to treat itching and hives in adults and in children age 2 and older, has been cleared for those 2 indications in children 6 months and older.

Allergies Causes:

Allergies are relatively common. Both genetics and environmental factors play a role.

The immune system normally protects the body against harmful substances, such as bacteria and viruses. It also reacts to foreign substances called allergens, which are generally harmless and in most people do not cause a problem.

But in a person with allergies, the immune response is oversensitive. When it recognizes an allergen, it releases chemicals such as histamines. which fight off the allergen. This causes itching, swelling, mucus production, muscle spasms, hives, rashes, and other symptoms, which vary from person to person.

Common allergens include pollen, mold, pet dander, and dust. Food and drug allergies are common. Allergic reactions can also be caused by insect bites, jewelry, cosmetics, spices, and other substances.

Some people have allergy-like reactions to hot or cold temperatures, sunlight, or other environmental triggers. Sometimes, friction (rubbing or roughly stroking the skin) will cause symptoms.

A specific allergy is not usually passed down through families (inherited). However, if both your parents have allergies, you are likely to have allergies. The chance is greater if your mother has allergies.

Allergies may make certain medical conditions such as sinus problems, eczema, and asthma worse.

Mild allergies like hay fever are highly prevalent in the human population and cause symptoms such as allergic conjunctivitis, itchiness, and runny nose. Allergies can play a major role in conditions such as asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening anaphylactic reactions.

A variety of tests now exist to diagnose allergic conditions; these include testing the skin for responses to known allergens or analyzing the blood for the presence and levels of allergen-specific IgE. Treatments for allergies include allergen avoidance, use of anti-histamines, steroids or other oral medications, immunotherapy to desensitize the response to allergen, and targeted therapy.

Definition:

An allergy is an exaggerated immune response or reaction to substances that are generally not harmful.

Allergies are abnormal immune system reactions to things that are typically harmless to most people. When you’re allergic to something, your immune system mistakenly believes that this substance is harmful to your body. (Substances that cause allergic reactions, such as certain foods, dust, plant pollen, or medicines, are known as allergens.)

In an attempt to protect the body, the immune system produces IgE antibodies to that allergen. Those antibodies then cause certain cells in the body to release chemicals into the bloodstream, one of which is histamine (pronounced: his-tuh-meen).

The histamine then acts on the eyes, nose, throat, lungs, skin, or gastrointestinal tract and causes the symptoms of the allergic reaction. Future exposure to that same allergen will trigger this antibody response again. This means that every time you come into contact with that allergen, you’ll have an allergic reaction.

Allergic reactions can be mild, like a runny nose, or they can be severe, like difficulty breathing. An asthma attack, for example, is often an allergic reaction to something that is breathed into the lungs by a person who is susceptible.

Some types of allergies produce multiple symptoms, and in rare cases, an allergic reaction can become very severe — this severe reaction is called anaphylaxis (pronounced: an-uh-fuh-lak-sis). Signs of anaphylaxis include difficulty breathing, difficulty swallowing, swelling of the lips, tongue, and throat or other parts of the body, and dizziness or loss of consciousness.

Anaphylaxis usually occurs minutes after exposure to a triggering substance, such as a peanut, but some reactions might be delayed by as long as 4 hours. Luckily, anaphylactic reactions don’t occur often and can be treated successfully if proper medical procedures are followed.
