Patient discussion about food hypersensitivity

Q. Can you define celiac as a food allergy? and if you can- how come you can't treat it with alternative medicine- like you do for other types of food allergies???

A. No, celiac is not defined as a food allergy, because the mechanism of injury to the bowel mucose after exposure to gluten containing products is much more severe than the regular allergic reaction. The damage caused to the bowel is by severe inflammation and destruction of the bowel "villi", and in a regular food allergy the only problem caused is either mal-digestion or other allergic manifestations such as a rash (aside from actual anaphylaxis).

Q. How long does it take for an allergy to occur after eating a food? Ok, I am allergic to peppers, each time I get an allergic reaction it takes longer and longer for the allergy to occur last time it was nearly 10 hours after eating the food this time it was 17 hours after eating the food. Is this even possible? I thought reactions occurred at max 4-6 hours after eating the food

A. i have a LOT of allergies. i am allergic to nuts very bad and i ate a chocolate with a nut in that a didn't notice, 10 seconds after digesting gave me a bad feeling in my throat and a few more seconds later i was violently sick and couldn't breathe very well and needed to call an ambulance 10 seconds later. i think its how bad the allergy, the quicker it starts to take effect.

Q. Is it possible to show external symptoms with a food allergy? The research I've done only mentions irritation of the throat and mouth, wheezing, etc. But is it possible to develop hives and itching on your back, arms, legs, but not have any irritation in your throat, mouth, etc, when you're affected by a food allergy, such as soy? Also, is it possibly a food allergy if the hives take a long time to go away, maybe a day or two?

A. Yes, it is possible. This exact same thing happens to me when I eat avocado products.
My skin whelps up, turn's red and itches like nothing else...
I hope that this helps and good luck with your allergies!
