Allergist Kentville

Allergist Kentville - Food allergies are normally mean an adverse immune response to a particular food protein. Reactions are different from various adverse responses to food like for instance pharmacological reactions, food intolerance and toxin-mediated reactions.

Usually, a protein found in the food is the main allergic element. These kinds of allergies occur when the body's immune system wrongly identifies a protein as a harmful substance. Various fragments of proteins are resistant to digestion. Such proteins which are not properly broken down during the digestive process are tagged by the IgE or the Immunoglobulin. These tags trick the immune system into thinking that the protein is harmful. When the immune system thinks that immune system is under attack, an allergic reaction is triggered. These responses vary from mild to severe. Several types of allergic reactions include dermatitis, respiratory distress and gastrointestinal distress life-threatening anaphylactic reactions like biphasic anaphylaxis and vasodilatation. These are extreme responses which require immediate emergency intervention.

Among the numerous common non-food protein allergies, one main allergy is a latex sensitivity. Sufferers of this particular protein allergy should avoid whichever contact with the problematic protein. There are various medications that could help prevent, treat, minimize protein allergy responses. Avoidance is amongst the main treatment choices as well as desensitization and immunotherapy. Many individuals who suffer from a diagnosed food allergy opt to carry an injectable form of epinephrine such as an EpiPen or Twinject. They usually wear some type of medic alert jewelry to be able to alert people around them in case they become incapacitated by their allergy.

Common Signs

There are many ways wherein allergies can present. Like for example, hives on the back are a common allergy symptom. Classic IgE or immunoglobulin-E mediated food allergies are classified as type-I immediate Hypersensitivity reactions. These allergic reactions have an acute onset, typically showing up within seconds of contact to an hour and may comprise: itching of throat, lips, skin, mouth, tongue, skin eyes or different areas, swelling of entire face, lips, eyelids, or tongue, a congested or runny nose, nausea, difficulty swallowing, hoarse voice, lack of breath or wheezing, vomiting, light-headedness, fainting, abdominal pain or stomach cramps. Obviously, symptoms differ from individual to individual. The amount of exposure to the allergic substance also differs from person to person.

Peanuts are one of the most common allergies. This sensitivity belongs to a member of the bean family. Some kids with peanut allergies do outgrow them, however, these allergies may be life threatening and severe. Tree nuts such as pine nuts, pistachios, walnuts and pecans are likewise common allergens. People who have an allergy to tree nuts could be sensitive to just one or maybe many types within the tree nut family. Various seeds like poppy seeds and sesame seed contain certain oils that have protein present. This could likewise elicit an allergic response. About 1 in 50 kids has an egg allergy. This particular type of allergy is usually outgrown by children when they reach the age of five years old. Normally in the case of egg allergies, the sensitivity is to the proteins in the egg white rather than those in the yolk.

Dairy allergies are one more common kind. The milk from cows, sheep and goats is a common allergen for a lot of the population. These sufferers are unable to tolerate dairy products like for instance ice cream, cheese and yogurt. Roughly a small portion of children, who have a milk allergy, approximately 10 percent, will also have a response to beef, because beef contains a tiny amount of protein that is found within cow's milk. Other common allergenic proteins are present within the following foods: fish, soy, wheat, spices, fruits, shellfish, veggies, natural and synthetic colors and chemical additives such as MSG.

Milk, eggs, peanuts, tree nuts, shellfish, seafood, soy and wheat are the top eight food allergies. Within North America, these account for over 90% of allergies to food. Sesame seeds are becoming a more popular allergen as well. There has also been a noted surplus of rice allergies in Eastern Asia where rice forms a huge part of the local diet.

Examples of Allergy Testing Consist of:
Skin prick testing is amongst the most common types of allergy testing. The results are immediately available and the test is easy to do. An allergist will typically make use of a bifurcated needle, which resembles a fork two prongs. Others can utilize a multi-test, that can look like a small board that has many pins sticking out of it. During these tests, a minute amount of the suspected allergen is put onto the skin or into a testing device. After that, the device is placed on the skin to prick and go through the top skin layer. This puts a small amount of allergen under the skin. If the person is allergic, a hive will form at the spot.

This particular test usually yields a positive or negative result. It is positive for quickly learning if an individual is allergic to a specific food or not since it detects allergic antibodies known as IgE. Skin tests cannot predict if a reaction will occur if a person ingests a specific allergen or even what type of reaction would occur with ingestion. Nonetheless, skin tests can confirm an allergy based on a patient's history of reactions with a certain food. Non-IgE mediated allergies could not be detected by this method.

Another useful diagnostic tool for testing IgE-mediated food allergies are blood tests. The RadioAllergoSorbent Test is a blood test which is called RAST for short. This test detects the presence of IgE antibodies to a specific allergen. A CAP-RAST test is a specific type of RAST test which could show the amount of IgE present to each allergen.

Researchers have been able to determine "predictive values" for certain foods. These predictive values could be then compared to the RAST blood test results. For instance, if a person's RAST score is higher compared to the predictive value for that food, there is a 95% possibility the person would have an allergic reaction if they ingest that particular food. This is limited to rash reactions and anaphylaxis. There are presently predictive values available for peanut, soy, egg, milk, fish and wheat. Blood tests enable hundreds of allergens to be tested from one sample. This consists of inhalants as well as food allergies. It is important to note that non-IgE mediated allergies cannot be detected by this particular method.

The double-blind placebo-controlled food challenges are known as DBPCFC. They are considered to be the gold standard for diagnosing food allergies, along with most non-IgE mediated responses. Blind food challenges are given to the individual. This involves packaging the suspected allergen into a capsule and giving it to patient and observing them for whichever symptoms or signs of an allergic reaction. Normally, these challenges occur within a hospital environment under the presence of a doctor because of the possibility of anaphylaxis. For the evaluation of non-IgE or eosinophilic reactions, diagnostic tools such as biopsy, colonoscopy and endoscopy are normally utilized.
