Different Types Of Food Allergies
3 types: Perennial - year-round symptoms usually due to something in your home - house dust mites, animal danders, molds, cockroaches. Seasonal - symptoms occurring only part of the year due to outdoor stuff - tree, grass or weed pollens & molds. Intermittent - symptoms triggered by occasional exposure to things you are allergic to - typically someone else' pet when you visit their home. ...Read moreSee 1 more doctor answer
Allergies occur when your immune system is triggered by envirionmental factors it should ignore--for example, pollen in the air, or dander on a cat or dog--and creates cells to fight against them. An allergic reaction typically causes itching, congestion, or drainage, and ...Read more
Many: There are many pathogens that cause food poisoning. It is often possible to sort them out based on onset of symptoms. Most of these causes of food poisoning are self limiting. If you have vomiting and diarrhea that exceeds your input you may need medication and possibly IV fluids although rehydrating orally is best. ...Read moreSee 1 more doctor answer
What makes hives come out, and do the different types of allergies cause different sizes or different types of hives?
Highly Variable: Allergy, broadly defined is hypersensitivity to what is usually an innocuous exposure in the general population. It is primarily directed against the protein in the substance. Symptoms can vary from rhinitis, dermatitis, hives, bronchospasm, vomiting, diarrhea, and if very severe, anaphylaxis. ...Read moreSee 1 more doctor answer
Yes: Definitely since one disease condition usually does not preclude you from getting another one. Certain foods are more dangerous than others in term of allergy. Peanut tops the list followed by tree nuts and shellfish. Some fruit allergies may just cause a transient itching in the mouth, other food allergies may cause anaphylaxis. However allergy to multiple foods is not too common but not rare ...Read more
Possible: Anything about food allergy is likely possible but I must admit that there has been no study ,to my knowledge, addressing this issue. Theoretically one can postulate the such allergic combination can occur. Do note however that cooking in general reduces the allergenicity of a food and perhaps that's the reason why we have not observed this type of problem ...Read moreSee 1 more doctor answer
Several classificati: There are several ways to classify asthma - based on symptom frequency & severity, control of symptoms while on therapy, associated conditions (atopic versus non-atopic), mechanisms (aspirin-sensitivity, exercise induced) and now more recently based on inflammatory cell types (eosinophilic versus neutrophilic) etc. Identification of precipitating factors & comorbid conditions also define it furthe. ...Read moreSee 1 more doctor answer
Great Question: That is a great question and one that is up for debate at every national allergy meeting as we are seeing more and more people diagnosed with food allergies every day. Unfortunately the best minds in the field have yet to come to a consensus and therefore we don't have any way yet of preventing the development of food allergies in children or adults. Continue to stay tuned. ...Read moreSee 2 more doctor answers
Asthma...: Asthma is actually one disease with many triggers. For example, for some asthmatics, exercise triggers their asthma to exacerbate and this is labeled exercise-induced asthma. Some patients are triggered by allergens while others are triggered by upper respiratory infections. In all cases, the asthma is the same but the triggers are different. ...Read moreSee 1 more doctor answer
Different Cartegorie: In general allergy medications are in several broad categories. Antihistamines ( like allegra, claritin, zyrtec that are taken by mouth and Astelin / patanase which are nasal inhaled antihistamines); steroids which can be oral (prednisone), inhaled for the nose or lungs and topically applied for the eyes and skin. ...Read more
Several: Milk allergy can have symptoms of hives, swelling and anaphylaxis (severe life threatening reaction). In infants, milk allergy can lead to asthma and nasal allergy symptoms--this is very unusual in adults. Also heiner's syndrome is a milk reaction in infants where they have pneumonia-like changes on chest x-ray, anemia and GI symptoms. Milk allergy can flare eczema (atopic dermatitis). ...Read more
More than one: Cancer can arise from different types of cells which is what gives it its name. Skin cancer on the skin surface is different than the cancer arising from the mucus membrane of the nose, which further has glandular cells and surface cells and pigmented cells in it. So a nasal cancer can be squamous type, adenoid cystic(glandular type) or a mucosal melanoma, each with a different behavior and course. ...Read moreSee 1 more doctor answer
Yes: Different people certainly can have different reactions to various foods if allergic. These reactions are unpredictable in nature. ...Read more
Is there a "carbohydrate" intolerance or just individual intolerances of different types of sugars?
Specific: About 30-40% of some populations will lose or never have the lactase enzyme need to digest lactose, a common sugar. A smaller number have a similar issue with the common fruit sugar fructose. If they don't digest it, it can loosen stools & cause cramps or other symptoms. Most other carbs are well tolerated by humans and once inside your system provide the main fuel for energy. ...Read moreSee 1 more doctor answer
Neither: Skin testing and blood test (serum specific ige) have different sensitivities and specificities. Either or both must be interpretted in light of the clinical picture. Frequently, patients with positive tests are not allergic and an oral challenge under the supervision of a board certified allergist familiar with oral challenges and treatment of anaphylaxis is needed. ...Read moreSee 6 more doctor answers
Different: They are both immune reactions but the similarity ends there. They involve different cells of the immune system, have different symptoms, onset and duration and are treated differently. ...Read more

My kids have food allergies, and even as a doctor, it scares me! if you are not sure, do not hesitate! get your child to an emergency room as quicly as possible, as every minute counts. Having Epinephrine pens will buy you time as well. Please discuss this with your child's docotr as well. ...Read more
Widely available: Even though blood testing for food allergies is widely available, indiscriminate testing should be strongly discouraged. The tests are very good at ruling out allergies, but have a very high false positive rate, which often leads to unnecessary anxiety and confusion for both patients and providers. This makes proper selection of patients and tests critical. Allergists are experts in this area. ...Read moreSee 1 more doctor answer
What type of benadryll and how much benadryll should I give my 17 month old baby? She is also 18 lbs..She has a minor food allergy..
Maybe none...: Benadryl only relieves symptoms, it is not needed just because there is an allergy. It helps if the symptoms are hives or runny nose, but likely won't help if the symptoms are diarrhea, vomiting, eczema, or asthma. The best treatment is to avoid what she is allergic to. If she does need benadryl, make sure it has no other ingredients, only diphenhydramine, and the dose is about 1/2 tsp. ...Read more
I have developed over 40 different food allergies in less than 6months. Full blood work and they can't tell me why? Its only getting worse. Help.
Be wary of labels: Some of the available skin tests are easily over interpreted as can blood tests. I suppose you didn't get labeled with many of these food allergies until the tests were done with no clear symptom patterns beforehand. Any such labels should be verified by an experienced board certified Allergist. These can happen but having been through much of this myself, I would be cautious in accepting it all ...Read moreSee 1 more doctor answer

Is a skin test for food allergies reliable? If i've tested negative can I assume that I am safe ingesting all types of foods?
Don't count on it: People can have adverse reactions to foods that are significant but have nothing to do with allergy. About 1/4 adults are intolerant to lactose sugar in regular milk & have a variety of symptoms. Red food dye #40 can give similar symptoms in many. Skin tests can be a guide, but maintaining a food diary & being vigilant about your changes in symptoms is often the best approach. ...Read moreSee 2 more doctor answers

What is the likelihood of being born with food allergies, asthma, and later on juvenile type 1 diabetes?
Depends: If you have pots and have symptoms from food allergies that can worsen fatigue or change your fluid balance, the impact will be negative but mostly related to symptoms. If you are asking if food allergies could cause pots, not likely. I assume you mean igg food allergies, not emergent ige allergies. ...Read more
No: Food allergy can present at any times in your life. Eating certain foods everyday does not increase your risk of getting allergy to that particular food. Instead, you have a higher risk of getting food allergy if you have other atopic diseases like allergic rhinitis, asthma, urticaria, eczema, and other food allergies.... ...Read more
Symptoms with eating: Food allergy symptoms occur within minutes to a few hours after ingesting or contact with food leading to hives, itching, swelling, nausea, vomiting, abdominal or less likely anaphylaxis. Avoiding the food resolves it. An allergist can review your symptoms and diet and assess for a food allergy vs. Intolerance. Both allergy blood and skin tests are not perfect, but can help guide the allergist. ...Read moreSee 1 more doctor answer
