Less so: The best treatment for food allergies defined as having symptoms after ingesting certain foods (and not just having a blood testing stating food allergy is present) is first and foremost, avoidance and secondarily by carrying epipen(jr) which is adrenaline which can be injected into the person's thigh asap after contact with the allergen. Prednisone is much less useful. ...Read more

If kids can grow out of food allergies, is it possible to grow into a food allergy? Within the last two years I have started getting sick with dairy.

If kids can grow out of food allergies, is it possible to grow into a food allergy? Within the last two years I have started getting sick with dairy.

Lactose intolerance: Allergies can develop with repeated exposure. Stomach upset from milk is not likely a true allergy. Genes code an enzyme that breaks down lactose, a milk sugar. As we age, the gene may express less and we don't tolerate milk as well. Some infants have the gene turned off, don't tolerate milk and need special formula. Undigested lactose can ferment by gut bacteria causing gas, bloating and pain. ...Read more

Hello. My allergist told me that based on the symptoms I've experienced due to food allergies that it's not safe for me to do a food allergy test. I'm devastated because I was hoping for the test to provide some sort of confirmation because I'm at a place

Try blood test: Although blood test (ImmunoCap IgE) for food allergy may not be as sensitive to skin test, the results are more specific. In your case, I think blood tests should be obtained first and skin test to follow if blood test turns out to be negative. In double-blind food challenges, many presumed food allergies turned out to be false. Avoiding too many foods may lead to nutritional deficiency. ...Read more

Does aspirin help or worsens food allergies? I have a cold and food allergy at the same time.

Does aspirin help or worsens food allergies? I have a cold and food allergy at the same time.

No effect: Aspirin should have no affect on your food allergies. It could cause GI upset, gastritis, etc. But that would not be related to your allergies unless you had pre existing gastritis, which it could worsen. If you have a GI diagnosis, you should talk to your doctor before starting Aspirin or nsaids like motrin. ...Read more

Dr. How to test for food allergies? How does allergy testing work in general? And what about non food allergy testing?

Two kinds: Of allergy testing - blood test for antibody levels and skin prick test (a small amount of the substance placed on a sharp tip that is pressed against the skin). The skin test is more likely to correlate with real allergy, however remember w both methods it can only suggest a possible allergy. Would leave interpretation up to ur allergist. ...Read more

Can a food allergy cause mental slowness/confusion? I have new food allergies (IgE testing) and trying to make sense of it all. Thanks!

Can a food allergy cause mental slowness/confusion? I have new food allergies (IgE testing) and trying to make sense of it all. Thanks!

Not likely: Many people with no food allergy will produce antibody that reacts to the food allergy panel. Thus, these tests need to be interpreted by experts who treat food allergy daily. Skin testing is often more accurate, but ones history of symptoms that follow an ingestion is critical as well. Yes, dizziness/fogginess can occur with allergy, but is transient immediately following intake. Be well! ...Read more

29yo. Never had food allergy but recent skin test had some allergies. Done for Chronic hives. What r the chances of going into anaphylaxis now?

Food allergy tests: If you never had anaphylaxis and you have been eating the positive foods regularly, the risk is low. You should not stop eating the foods. If it's a food you never eat, it could be higher. The size of the positive reaction also matters. Over 9 mm, there is more chance, but it's still highly unlikely if you have never had a severe reaction before. Try elimination diet for the hives though. May help ...Read more

I have health anxiety. My fear is food allergy and that my tongue is going to swell because of the food i eat. Have no food allergy or other allergies?

You ready to work ?: Worrying about a health issue you don't have is a smoke screen you erected (likely subconsciously) to shield your thoughts from your real fear. If you waste time on made up issues you can be stuck forever. If you are ready to do the work & find a good therapist to help, you can get past this but it requires looking for the real issue you fear. ...Read more
