Testing For Food Intolerance/sensitivities
0

12 posts in this topic

I'm new to all this and awaiting my cp results. I've been reading these forums and have a few questions about getting diagnosed/tested. I notice some people label themselves with different allergies or sensitivities to gluten, soy, yeast, dairy, etc. I am curious how do you find this out? Do you see an allergist? Do you get a pin prick test or blood work? Does your gp help you figure this out? If my cp is neg for celiac, can it still show intolerance, or is that another test?

I personally don't think I will be positive for celiac, but I think I have an intolerance or sensitivity (is that the same thing?) to something. My symptoms are more constipation, bloating, mental fog, tiredness, and difficulty keeping my weight down, despite intense exercise. I always though my problem was just "carbs" and only could distinguish that I ate some carb (bread, pasta, etc), which is why I felt bad. I have tried to be low carb for years. Now I do think it is more specifically related to wheat, but wonder about yeast and soy as I see others mentioning them. I have a large amount of environmental allergies and food allergies to nuts and egg whites. However the last I was tested for food allergies was 30 years ago. If it is not celiac, how do you find out what it is?

Basically, the only difference i've heard between celiac and an intolerence is that celaic does damage due to being an AI disease.

People often times do elimination diets. Removing everything that could potentially be problematic and then slowly (once a week or so) adding an item back in.

I have never been tested for celiac and AFAIK, I do not have any gluten issues. My daughter did (doesn't currently) but that's what brought me here.

Long story short with her, she was thought to have ADHD by her teachers. But I didn't believe this. After taking her to a variety of Drs., my mom's Naturopath finally said he could test her for food allergies. He did and said that she had quite a few. We changed her diet and it was like we got a new girl! Lots of things cleared up.

What he did was a blood test for IgG allerigies which most medical Drs. will say are not allergies at all but sensitivities or intolerances. We were told to have her restested in three years. But... We did not like this Dr. He charged many thousands of dollars for the test and insisted that we buy supplements from him that I thought we did not need.

So we went to an allergist who didn't believe in the IgG allergies but said that if the foods caused us problems, to avoid them. She tested us both and we were found not to have allergies to those foods. Technically, allergies cause a histamine response. And this can be life threatening. I was found to have OAS (oral allergy syndrome) to pistachios and almonds. But... The allergist only tested us for the specific foods that we were told we were allergic to. No others. Daughter is currently having stomach issues and the GP that she saw suspects food allergies or intolerances that we have yet to ferret out. The food allergies were tested for via a skin prick test.

We found another Naturopathy (now deceased) who tested my daughter twice (I think) and me once. Each time we were tested, we changed out diet.

Then we needed to be retested again but I couldn't find a Dr. to do it. So I did a hair test online. I know some people think this test isn't valid but it did seem to work for us.

I also have some other issues with foods that I do not test as having a problem with. But if they bother me in any way, I just avoid them. Like garlic in more than a tiny amount and melons.

So the cp test should show "intolerance", even if there is no damage?

The elimination test is difficult for me as I don't have great will power to resist the large amount of things I would test for, such as most carbs, starches and sugars. Also, other than edema and constipation, my symptoms are so subjective, such as a general overall feeling of being unwell and brain fog. It is just Not scientific enough for me and feels like self diagnosing. I know I feel great on just meat and vegetables, but at this point in my life I want to know if this is just a diet issue, or if there is an internal autoimmune response that can compound into further issues down the road.

Thank you for your story! Did your allergist do any blood testing or was it just pin pricks?

If by cp you mean Celiac blood tests, no, it doesn't show intolerance. It measures if you are making antibodies. Intolerance means you don't make antibodies but have problems when you eat gluten. The only way to know about intolerance is, once you have had all the Celiac testing, stop eating the food you think you are intolerant to. See if it helps.

You will find many fringe medical sites willing to sell you tests for gluten intolerance, so be careful.

This article discusses some research done on non-celiac wheat sensitivity. It is not the same condition as celiac disease but can cause similar symptoms.

Thanks Karen, for breaking my link! :) Just kidding. I fixed it in the post above. It didn't work for me either.

Thank you for your story! Did your allergist do any blood testing or was it just pin pricks?

She did a blood test for bees because she said if I were really allergic like I was told that I was, this could cause a deadly reaction. That test came up negative so I had to take a series of stings with needles. I was injected with the venom from various stinging insects. It really hurt! But I wasn't allergic.

Funny, i found out i was allergic through the plain old fasion way. Mine aren't life threatening, but the area swells up so bad that benadryl is needed (once got stung on my hand, I couldn't move two of my fingers for a couple of days).

    • Hi, Ok good advice and I am sincere when I say how much I appreciate a lot of the responses, advice and encouragement that have been posted here. I'm not sure what a nutrionist is but a dietician (here in the U.K.) is a heavily regulated medical profession and my dietician is based most of her week in a hospital where doctors and MD's as they are known refer patients to her for help. She works every day with celiacs, dh sufferers and people with crohns, ibs etc and seeing my skin, listened to what I was saying (particularly about how my redness and blisters resolved on a gluten free (though not wheat free) diet for several years, and sent a report to my doctor/MD requesting a battery of tests - tests that can indicate dh, celiac and associated complications. I also have a friend with a wheat allergy and two with celiac (all diagnosed) and they are encouraging me to go ahead with getting these particular tests. So that's great but reading the above quote that suggests that situations like sharing an oven used to cook gluten-containing pizza, should not cause a gluten reaction. I thought, my god what's the point of going through these tests if my recent reactions aren't actually to do with gluten. Although my dietician is concerned about possible dh and has been through years of medical school, I also really trust the advice of an advanced member on this site and if they think oven-sharing shouldn't cause any gluten reaction, what hope do I have with an MD? It has taken me years to pluck up the confidence to ask for any medical help because I feared that sort of response along with a focus on psychological issues and hormones etc early on in the thread (even though, I only started feeling depressed since yesterday). Actually, I'm a mental health nurse so it's good to see people are alert to these issues but I am also pretty familiar with depression and I know that many people with physical health problems are fobbed off by doctors with talk of depression, stress, and hormones. I'm sorry that I took the (above) quote to heart and I know that I allowed that to colour my perception of the whole thread, which has been helpful in many ways. Best wishes to you all, even those I didn't agree with! Rhian 
    • I thought maybe doing a trial period to see if he reacts positively to being gluten free and then adding it back to see if symptoms come back would maybe be helpful to the doctor? But I guess that's true, it might skew things regarding any future tests that might be warranted. 
    • If you haven't had her tested yet please do not go gluten free. Get the celiac testing first as if she does feel better gluten free when she has to go back on gluten for testing she may have much worse symptoms.  There will also be a higher risk of false negatives.
    • I did not mean to imply that you should put him on a gluten free diet.    If you suspect a problem with gluten, please get an opinion from a GI who is celiac savvy.  All celiac testing requires a patient to be consuming gluten.  The slightly equivocal TTG?  That warrants a gene test at the very least.   http://www.mayomedicallaboratories.com/it-mmfiles/Celiac_Disease_Diagnostic_Testing_Algorithm.pdf
