Pollen allergy diagnosisOral allergy syndrome (OAS) is a well-recognized, but poorly understood condition. It is characterized by a burning sensation or pain in the mouth and swelling when you eat specific foods that cross react to pollens to which you are allergic. Interestingly, the specific foods that cause this reaction are well established to cross-react with certain trees, grass, weeds or pollen, house dust mite or latex.
Although this reaction is well documented in the literature of allergy is not commonly recognized or diagnosed by most physicians including some allergy specialists and many specialists in the stomach. Several websites include allergy food lists related to certain pollens, dust mites, or latex. However, a list that is easy to read and interpret can be difficult to find. In addition, the names of some pollens or common links between a group of pollen and a group of foods can be confusing.
In its classic form the OAS should be easy to recognize. After eating a food associated with a pollen to which you are allergic near you experience immediate burning sensation in the mouth or throat with or without swelling. However, it is commonly recognized that often in medicine, the symptoms do not occur in the classic or regularly in an individual. Written another way doctors are taught patients do not read the textbooks. Therefore, you may experience changes in the reaction, such as swelling of the throat or tightening, burning when swallowing, a lump in the throat or a feeling of difficulty swallowing, but not make the connection with what you ate or what you are happening to you.
You or your doctor may misinterpret their symptoms. People often assume that just because it happened a choking spell on foods that are poorly chewed, swallowed too fast, or eat or drink while hot or cold. Commonly, it is assumed that one of the esophagus (swallowing tube), disorder, especially acid reflux with a hiatal hernia is the cause. Acid reflux can cause called esophageal stenosis or constriction ring can lead to a feeling of adhesion of food, but this is usually associated with heartburn or symptoms of food that gets stuck then asks an upper endoscopy or examination scope. Other times, especially if they occur in an elderly person, a neurological condition such as stroke or Parkinson’s disease is blamed. Doctors sometimes decide that their symptoms are due to a nervous reaction or neurosis that historically was called Globus hystericus. The hystericus part of the expression is usually reduced in these days or shorter period Globus Globus sensation mainly because it is not proven to be due to a mental problem. However, Globus diagnosis can be arrived at your complaint if you feel a lump in my throat and an assessment appears to turn anything, even if the OAS was not considered or excluded.
An unusual condition that has more recently been recognized in the field of gastroenterology (diseases of the stomach and intestines), which may be related to one or OAS variant called eosinophilic esophagitis (EE) or allergic esophagitis. It was first described in the pediatric population, but is now known to occur in adults. Classically described in adolescents and young adults who present with food stick episodes without heartburn or acid reflux symptoms, associated with a strange look of endoscopy in the esophagus (lighted scope examination of the upper gastrointestinal tract). What does the doctor believes that the scope is that the esophagus is like a cat esophagus. That’s what it looks like it has rings (cats have cartilage rings in your esophagus, not) and this is known as ringed esophagus or felinization esophagus. A biopsy of a ringed esophagus or felinized appear (which is also often reduced in the resulting food sticking) microscopic signs of allergy was noted. The coating shows numerous eosinophils, a reddish pink than white blood cells characteristic of allergic conditions appear. These eosinophils release chemicals such as histamine that trigger inflammation, pain, and tissue damage.
Food allergies are commonly found today at EE but sometimes finding a traditional food allergy skin tests or IgE blood test is negative. Treatment is avoidance of known food allergens and swallowed nasal spray steroids that are designed for use in the nose for nasal allergies. Although pollen allergy shown, however, eosinophilic esophagitis (EE) may be a variant of the OAS.
Eosinophilic allergic eosinophilic gastroenteritis and colitis or also exist and can be diagnosed by biopsy of the stomach, small intestine and colon, respectively. Allergic colitis usually seen in infants with cow’s milk protein allergy. It presents as colicky abdominal pain, diarrhea, weight loss and bloody diarrhea in infants on cow’s milk or, sometimes, the formula in infants whose mother is ccontradad drink a milk cow.
Allergic gastroenteritis occurs in any age group usually presents as abdominal pain, with or without intestinal obstruction or perforation, diarrhea, anemia, weight loss and microscopic bleeding in the intestinal tract also known as fecal occult blood. This bleeding is detectable only by special chemical stool tests known as fecal occult blood tests (FOBT) or fecal guaiac tests.
At least some people with food intolerance does not make sense on limited daily information diet, blood tests, biopsies, or allergy test may have a form of the OAS. In other words, the presence of known pollen or latex allergy could be that predispose reactions to foods known to cross-react with allergies noted in the OAS. However, instead of the classic symptoms oral allergy syndrome stomach and other intestinal symptoms or no gastrointestinal symptoms may result.
The support of this concept can be found in the detailed study of people food intolerance. Known to pollen or latex allergies, any known food allergies or intolerance, including intolerance to gluten (celiac disease) and casein intolerance, are asked to complete a series of assessments of symptoms and severity rating scales followed by a strict elimination diet. This is followed by the re-evaluation of the response of symptoms, while reintroducing foods one at a time while monitoring the repetition.
This type of analysis is the basis for Neopaleo specific diet. An online diet symptom diary also available. A simplified table illustrating the common foods that can cross react with the general categories of allergens from pollen and latex allergy is available. Food intolerances are more commonly recognized as a common cause of illness and symptoms. Individualized nutritional counseling and dietary elimination trials may be more useful in discovering possible links to what you are eating and how you feel.
