Food Allergy and Anaphylaxis in an Irritating Nutshell

A person will never know if they are allergic to a certain type of food unless they have eaten the food allergen itself. It takes a certain amount of food for the reaction to take place and trigger a symptom.

Food allergy and anaphylaxis are closely related, but they have their own defining differences that will be discussed as you read on.

Plus, a person can also develop allergic reactions to foods that are closely related to the original food allergy he or she has. Say, an allergy to oysters can also lead to an allergic reaction when the person eats shrimp, crabs, or fish.

In food allergy, the individuals immune system reacts in two ways. The body may respond through the use of mast cells. These mast cells can come about at just any part of the human body but its favorite spots make itself known to the world is in the throat, lungs, eyes, skin, and especially the organs of the gastrointestinal system. The other type of response is through the bodys release of immunoglobulin E antibodies that travel through the blood system. It then eventually causes the discharge of the body chemical histamine which then causes the activation of allergic reactions in the common body sites previously mentioned.

On the other hand, anaphylaxis is derived form the Greek words ana and phylaxis, which subsequently means back and protection. It is the abrupt allergic response that is much more intense than the common allergy which can be lethal to the sufferer. Chief causes of anaphylaxis include insect stings, skin contact to latex, medications, and food. Anaphylaxis may also be idiopathically caused or, in lay mans terms, unknown causes.

Like in food allergy, anaphylaxis involves the reaction of the different body sites; the only difference is the intensity of the response and only a small amount of the allergen is needed for the reaction to take place. The time span before signs and symptoms become evident ranges from within a few seconds up to a few hours after allergen exposure.

Anaphylaxis can come about following the intake of food, skin contact, or even as simple as inhalation of the food aroma. The life threatening type of anaphylaxis is called anaphylactic shock. In anaphylactic shock, only a tiny amount of the food allergen is needed to cause death to the sufferer within moments of exposure.

Individuals who are in danger of undergoing an anaphylactic reaction are those who have a history of allergy to food, asthma, and eczema. They are more likely to experience an anaphylactic response that can be fatal. Another population group who are also at risk of anaphylaxis, through the evidences of current studies that have been conducted, is teenagers who are afflicted with a certain type of food allergy. This is due to the fact that teenagers have frequent tendencies to eat out, are daring and experimental in their endeavors, and are more likely to fail to identify symptoms of anaphylactic reaction. Moreover, teenagers have tendencies to forget to carry with them essential medications which can either be caused by self-consciousness common to their age group.

Symptoms of anaphylaxis may be similar to that of food allergies. Basically, an incident of anaphylaxis initially starts with an itchy or irritating sensation, and some individuals experience a metallic after-taste. Anaphylactic symptoms may also include hot flashes or sudden warm feeling, inflammation of the throat and oral cavity, hives, dyspnea or labored breathing, low blood pressure, diarrhea, gastric irritations, and fainting or loss of consciousness.

Furthermore, there are cases wherein the symptoms fade away for a moment but then come back within a few hours; this incidence is known as biphasic reaction.

To prevent food allergy and anaphylactic reactions, careful scrutiny of food labels, diet modifications, specific instructions in food orders in restaurants, and certain medications can be of great help in reducing the incidence of any type of reaction. Moreover, a consultation to the physician is advisable for an efficient management plan and if allergies seem to run in families because it can also be hereditarily caused.

Food Allergy Overview and How to Fight It

Isnt it annoying when you smell the delicious aroma of a meal only to find out that it has an ingredient to which you are allergic? Ah! The demise of every person with food allergies! It is no fun to watch other people devour food that seems so delicious but you cant take part of the experience. How many times have you encountered comments like, great food isnt? And sometimes you just cant bear to admit you are allergic and just smile as if you knew how it tasted.

Then you try to ask questions, what is food allergy? What are causing these annoying symptoms? Whats happens inside the body during allergic reactions? Ah! Understanding ones own health condition will better help them accept and overcome whatevers bothering them.

To start with, food allergy is unusual reaction to certain type of food allergen. An allergen is the substance or thing that causes the allergic reactions. Exposure to the allergen sets off the alarm in the human immune system which consequently releases antibodies to fight off the invasion of the perceived foreign body that is the food allergen. It then causes the symptoms you would see when you are in a state of allergic reaction.

The aforementioned is just an overview of the whole picture. Looking more closely, allergic reactions undergo two courses of action. The initial course is the release of immunoglobulin E or IgE by the immune system into the blood stream. IgE is a food-specific antibody and a protein that is the bodys immune defense against the food allergen.

Following the initial response is the attachment of the IgE to the mast cells. These mast cells are present in body tissues specially locations of the body where allergic reactions are common. These locations may include the lungs, skin, nasal and oral cavities, and the gastrointestinal system.

As for the food itself, you may have noticed that you are not just allergic to one type of food. There are instances that you experience an allergic reaction to oyster and then later you found out that you are also allergic to crabs and other seafoods. This occurrence is what medical professionals call cross-reactivity, wherein an individual can be allergic to closely related or similar types of foods.

The only way to deal with this unfortunate mishap is to try as best as you can to avoid the foods that set off allergic reactions in your body. There is no cure to food allergy but there are medications out there that can alleviate its symptoms. With the help of a medical health professional, you can be assisted in the ways you can avoid exposures to food allergens. Nutritionists may teach you alternative ingredients or foods to replace the food that will be eliminated from your diet. Also, make it a habit to check food labels for possible ingredients that you may be allergic with and do not hesitate to warn the restaurant employees, like the waiter, about your food allergy to prevent any unwanted accidents.

Individuals who are highly allergic are advised to put on medical alert necklaces or bracelets which declare your condition. As for the medications, some patients who are very vulnerable are also advised to bring with them at all times a self-injectible epinephrine, which is prescribed by the doctor, that can be of great help during sudden attacks of allergic reactions before seeking out for the assistance of an emergency team.

Other medications are antihistamines, bronchodilators, and corticosteroids. Antihistamines help improve symptoms of rhinitis, hives, rashes, and gastrointestinal problems. Corticosteroids alleviate the severity of inflammations of the skin and in other areas of the body. While bronchodilators are utilized to open up air passages of the respiratory tract that has become inflamed which would have resulted to breathing difficulties.

To understand more about your food allergies, you can consult your physician. There are also comprehensive books in the market that can be easily understood by just about anybody that has complete information about food allergies and how to fight it.

Fighting Off Food Allergy Reactions

Allergies to food are commonly dealt with by the avoidance of the allergy-causing food. When the allergen (the one that causes allergic reactions) has been recognized, the patient is then advised to eliminate it from his or her diet. This is achieved by revolutionizing the food prepared and reading carefully food labels on food products. A specific instruction when ordering food also helps avoid allergic mishaps when eating out.

All this cautiousness is due to the fact that there are individuals out there that are highly allergic in which even a tiny amount of allergens can cause major symptoms. Plus, there are also food preparations that contain some common food allergens which the average person would not usually link together.

To prevent exposure to foods that you may be allergic with, self-awareness is very important. You should know the food culprits that are causing these uncomfortable reactions. Knowledge can help you and your physician in formulating a management plan for your allergy. You should also make it a routine to scrutinize food labels when checking for possible food allergens included in the ingredients. During eat outs, do not hesitate inquiring about the ingredients of the meal you are planning to order.

Another precautionary measure, especially for those who manifest severe allergic symptoms when exposed to a food allergen, is the wearing of necklaces or bracelets provided by a medical institution to alert other people about your allergies in case of an accident, for example, to a state of unconsciousness.

Patients are also advised to constantly bring with them epinephrine self-injectibles which are prescribed by their physicians. Their physicians will instruct them how to self-administer the medication during an episode of allergic reaction.

If symptoms seem to be getting intense, emergency medics should be called to help transport the individual to the nearest hospital. Severe and sudden allergic reactions are also called anaphylactic reactions. Anaphylaxis may be fatal if not treated quickly.

Other than epinephrine injections, there are still other medications that can be prescribed by the physician to deal with allergic reactions to food. These medications would include bronchodilators, antihistamines, corticosteroids, and adrenergic agonists.

Bronchodilators relieve symptoms that are associated with difficulty of breathing. It basically dilates the bronchial air passageways of the respiratory tract that have become inflamed due to the allergic reaction which eventually helps the patient breathe normally. Highly allergy-sensitive individuals should carry with them fast-acting bronchodilators if they also experience asthmatic attacks from time to time that may be triggered by the allergic reaction.

Antihistamines alleviate symptoms like sneezing, runny nose, hives, rashes, and gastrointestinal discomforts. And corticosteroids lessen the severity of skin irritations and other inflammation caused by the allergic reaction. Antihistamines can be available in syrup or chewable tablet for easy access when a sudden allergic episode occurs.

Adrenergic agonists are utilized during emergency treatment for anaphylactic reactions. Results are immediate and highly effective. Adrenergic agonists typically alleviate symptoms of angioedema, cardiovascular collapse, bronchospasm, and hives.

In addition to medications that fight off symptoms of food allergies, there are treatments that are causing quite a stir in the medical world although there are not enough studies that have been conducted to prove that these treatments are effective.

One these revolutionary treatments includes the desensitization of the patient by administering injections of small amounts of the food allergen on a regular basis. This treatment claims that it can eventually make the patient endure the food allergen in the long run. Another is the introduction of a diluted substance that contains the food allergen underneath the tongue thirty minutes before the actual food intake. This treatment works in a way that it will defuse the symptomatic manifestations of the consumed food allergen.

Lastly, bear in mind that there is no cure to food allergies. All the aforementioned are only there to help alleviate the symptoms of allergic reactions.

Warning Signs of Food Allergies

As you may have known already, food allergy is an unusual reaction to food that is elicited by an exposure to certain food types which then creates a response from the immune system. The reaction that the immune system eventually generates will then cause discomfiting symptoms.

Looking more closely, food allergens (the ones that causes allergic reactions) are proteins that unfortunately withstood the high temperatures of cooking as well as the acidic substances and enzymes of the gastrointestinal system. These allergens consequently live on to pass through the linings of the gastrointestinal tract, disperse into the blood circulatory system, and travel to organs of target, which results to different allergic symptoms all over the body.

Food allergy symptoms are commonly noted as irritation of the skin which may involve hives, eczema, and a simple rash. Other symptoms may also include irritations in the gastrointestinal organs like vomiting, indigestion, diarrhea, stomach aches, and nausea. Through the years, there have been numerous documented allergic reactions seen in a lot of people, the following is additional information about other allergic symptoms that even you have experienced but have failed to take notice:

– insomniac tendencies or sleeping difficulties
– moodiness
– fatigue
– heartburn
– constipation
– symptoms that resemble arthritis
– canker sores
– nocturnal enuresis or bed wetting
– inflammation of the face and lips
– rhinitis
– migraine
– wheezing

Furthermore, allergic reactions to a specific kind of food can also generate a specific symptom. Therefore there are symptoms that can pinpoint to a certain type of food allergy which can then be quite useful in figuring out what medications to administer and the formulation of a management plan. In other words, it is possible to determine the source of the allergy by evaluating the symptoms.

Simple headaches are usually symptoms of an allergic reaction to chocolates and wheat. Migraines, on the other hand, are typically caused by an allergy to cheese, nuts, citrus fruits, tomatoes, milk, eggs, and MSG or monosodium glutamate. Monosodium glutamate is a chemical used for seasonings in a lot of foods but only those which have excessive amounts can cause allergic reactions.

Eczema or atopic dermatitis, which is a swelling and drying of the skin, can be seen in allergies to citrus fruits, eggs, and tomatoes. Hives or urticaria is also a form of skin irritation which is represented by elevated skin welts that are reddish. Hives can be very itchy, this allergic reaction is common among tomatoes, eggs, shellfish, mangoes, pork meat, nuts, and strawberries.

Asthma is commonly seen in wheat and egg allergies.

There are also allergy manifestations that affect the physical energy, consciousness, and emotions of a person. These reactions can be regularly seen in allergies to wheat, soybeans, corn, and milk.

As you may have observed, many types of foods share the same symptoms most of the time. A careful assessment and physical evaluation is needed to at least determine the source of the allergy. It is not only in the symptoms that medical professionals can determine what the source of allergy is but also through blood tests, diet eliminations, and food challenges. Careful assessment of daily food intake by the patient can be of great help in pinpointing the culprit and as well as a comprehensive analysis of the symptoms observed.

Furthermore, a consultation with a reputable allergist who will be part of the medical team can assist you in fighting your allergy that may have caused you great discomfort in your daily life.
