Common Allergens And Their Symptoms

Testing for food allergies is an important step to determine if you have a reaction to a particular food or drink. An intolerance to foods that are common allergens will cause a negative response to the same foods when they are consumed. The most common food allergies include peanuts, shellfish, wheat, cow's milk and tree nuts. Each of these foods contain different sets of proteins that can cause a negative reaction. Some common allergens include:

Allergic reactions can be triggered by several factors. Exposure to allergens is one of the main factors. In the past, food allergies were often attributed to poor digestion or other unknown reasons. Today, however, doctors have identified specific genes or cells within the immune system that can cause allergic reactions. It has been proven that people with these genes are more susceptible to food allergies.

If testing for food allergies is done according to the specific foods identified in the digestive system, then it is more likely to produce a positive result. However, there is an increased risk for negative results when testing is done according to a careful history of allergic episodes. Food allergy tests are conducted on a part of the individual which has a slightly higher immunity to the allergen. In most cases, the individual with the highest level of resistance to food allergies is the first to be tested. This is due to the fact that if the individual is highly allergic to one type of food, he/she should have developed the reaction consistently over time.

There are two further tests which can be done to confirm the diagnosis of food allergies. One of these tests involves administration of a nasal allergy test. This test is known as the nasal challenge test. When the allergist injects an aqueous solution into the sinuses, it is possible to identify any potential allergens that may have been missed by an initial visit to the allergist.

The other test employed by allergy specialists is a skin test known as the patch test. This test is very similar to the normal allergy test that is conducted by doctors using the patient's blood. However, since it only involves the application of a small amount of a specific allergen on the patient's skin, there is a much higher degree of reliability for the results obtained from this test. Because this test can only identify those allergens which have a greater affinity for humans, therefore it relies heavily on the knowledge and experience of the allergist as well as the expertise of the laboratory staff.

Testing for food allergies is also performed on individuals who exhibit signs of having anaphylactic shock. This consists of two separate procedures. The first involves the stimulation of the immune system to release histamine. When histamine is released, it causes swelling within the mouth and throat area. A second procedure uses a method known as EIA (endoscopic innervation).

The Food Allergy Panel has completed thousands of allergy tests and performed hundreds of evaluations. Because food testing can be extremely complicated, allergy specialists have made it possible for most individuals who experience hives or symptoms related to allergies to obtain a quick diagnosis by undergoing one of these simple tests. Food tests are usually simple and easy to do not require any special equipment to perform. This means that individuals suffering from food allergies can receive a proper diagnosis and start getting their lives back.

As with any health condition, it is very important to know what to do if you believe that you may be allergic to a particular food. In the case of food allergies, it is important to know exactly what you are allergic to keep a food diary. Keeping a food diary is similar to keeping a health diary in that it will help you to monitor your symptoms and provide you with information about how your body is reacting to various foods. In addition to a food diary, it is also important to know what you should be doing to decrease the possibility of suffering from hives or other types of symptoms. Common allergens include: coffee, eggs, soy products, fish, shellfish, peanuts, wheat, peanuts, corn, sesame seeds, oranges and more.

What Food Allergies Is and How You Can Recognize Them

Food allergies occur when the body's immune system wrongly identifies proteins found in certain foods as a potential threat. Because of this, some chemicals are introduced into the body which result in an allergic reaction. It is these chemicals that ultimately cause the actual symptoms of a food allergy. If left untreated, however, food allergies can lead to severe illness and even death. Peanut and tree nuts are two of the most common food allergies. Many children have a food allergy to either one or both tree nuts and/or peanuts. A severe reaction may take hold if they are exposed to both tree nuts or peanuts at once. Overdosing on peanuts or tree nuts (especially peanuts) can lead to a life threatening high fever. Tree nuts and peanuts are both protein rich and have a long chain of amino acids. They are also both rich in protein and have several essential amino acids necessary for human development. For this reason, they are frequently found in a person's diet. They are als...

How to Deal With Stress Face Rash

Stress can really cause a great deal of skin damage. Some people are not even aware that they have been under stress until they have symptoms such as a face rash or eczema. Other people have no idea that they are stressed until it is too late. When you are constantly stressed out, your body puts on a lot of weight and causes your skin to become thin and fragile. This makes you more susceptible to many different types of skin problems. The first thing you need to do when you think you might be stressed is relax. If you must tell yourself that you are stressed, then do so during a calm, peaceful moment. Do not think about the stressful situation during this time. You are better off focusing your mind on something else. This will help to distract your mind, which in turn helps you to relax. Getting enough sleep is crucial if you want to stay healthy and work well at all times. Try to go to bed at least the same time each night. You should wake up feeling refreshed and ready to take on you...

How To Reduce Your Exposure To Allergic Reactions To Ragweed

Ragweed is probably one of the worst known environmental allergens which doctors to see, and it is estimated that up to 10 percent of Americans have it. "It's everywhere - on our clothes, the foods we eat, our cars, even our hands," says Mary E. Zuber, MD, a dermatologist in Scarsville, Utah. "We know that ragweed has the potential to cause problems for people who suffer from asthma or allergic rhinitis." What's more, the extent of the problem is probably under-recognized, since many patients do not realize they're prone to ragweed until it is too late. Unfortunately, the extent of the problem may also be under-treated, because doctors are less likely to look for skin rashes, itchy nose, sneezing, watery eyes, coughing, and chest congestion - all classic signs of ragweed allergy in humans. Even in areas where ragweed allergy is not common, the plant can still be a big problem, especially during ragweed season (also called autumn leaf fever) when it launc...

What Are the Symptoms of Bladder Cancer?

Smoking is a major risk factor for bladder cancer, as well as for most other forms of cancer. This is simply because tobacco contains carcinogenic (carcinogenic) substances. If you smoke heavily for years, these substances gradually permeate into your blood stream and are metabolized into your urine, where they remain inactive. Eventually, the toxins begin to attack healthy cells in your body. Cancerous cells begin to rapidly grow, while healthy tissue gradually deteriorates. As a result, bladder cancer progresses slowly over time. This type of cancer is called non-Hodgkins lymphoma, and accounts for more than 90 percent of all malignancies. One of the key signs of bladder cancer is hematuria--a decrease in the volume of the urine that a person produces. Hematuria is caused by a decrease in the number of red blood cells produced by the white blood cells. When there is an increase in the number of red blood cells, the oxygen level in the urine increases. Because more oxygen causes a hig...
