Eat Gluten Before Tests?

Ok, I have been gluten-free since May 1 of this year. I had blood tests ordered in November of last year and they came back fine, but my dr ordered every test EXCEPT the ttg and ama (i think thats right.) We are waiting for new insurance, so it may be a couple weeks until i can get to the GI Dr. I guess my question is should I go back on gluten, now, keeping in mind I have finals in about 2 weeks, or should I wait until school is out (so I can TRY to handle being glutened EVERY DAY without having to worry about school and concentrating)? Also, if I go back on gluten, do I realllllly HAVE to be on it for months to get positive biopsy? Thanks for responses in advanced.

Kassandra,

If they didnt run the tTG or EMA...and you plan on getting retested you may want to be back on gluten for more than 2 weeks for accurate results.

You do need to be back on gluten for a few months (at least) prior to the biopsy. Even if the biopsy is negative....you may still have Celiac. The biopsy is "hit or miss".....and alot of times they miss.

If a firm diagnosis is important to you...I would recommend 2-3 months back on gluten before retesting. If the diet is working and symptoms are too unbearable while on gluten...I wouldnt put myself through all that. I'd just stick with the diet.

Please do wait till after finals if you feel you have to do a challenge to satisfy your doctors. It sounds like you already know gluten is a problem, are you having issues still that might mean something else is going on? If that is the case being gluten free will not mask any symptoms or test results other than the ones for celiac. If you are planning on challengeing just to 'prove' to the doctors that this is medically needed be sure to keep them informed of any violent reactions like seizures, bleeding, etc that may appear.

Yes, you do have to eat gluten for that long for any chance of an ACCURATE test.

All that being said: if you do better on the diet, you do NOT need to do anything you don't want to do. My drs didn't do the right tests, and did the biopsy while I was gluten-free. Other drs have tried to make me go back on gluten and I refused to---because I get so violently ill. Weigh the benefits and the risks of it...but keep in mind, you don't have to do it if you have reservations about it.

Can anyone tell me how much gluten you need in your diet before the endoscopy and how fast the intestine is likely to heal if your gluten intake is minimal?

I was told before the test to make sure I eat gluten, and the recommended way was to eat a slice of bread per day. I don't eat bread very often and I just thought I'd carry on with my regular diet which contains gluten anyway. I eat pasta at least twice per week, and numerous other items which I know contains the stuff, but my appetite is quite weak and I fear that I might not have been eating enough.

You need to be eating the equivalent of about four slices of bread for several months before a biopsy to have any hope of it being accurate.

So, while it is possible that your biopsy will be positive, it may also come back false negative, due to you not eating a lot of gluten.

Why don't you just try the diet and see how you feel?

Kassandra, you definitely shouldn't do a gluten challenge before finals, you might not make it through.

Personally I think a gluten challenge is a terrible idea. Your villi have healed, you feel much better. Now you are thinking of destroying your villi again on purpose, which may lead to getting bowel cancer down the road, definitely nutritional deficiencies, and can cause irreparable damage, just to prove you have celiac disease, even though your diet response has already proven that you can't tolerate gluten.

Would your doctor also order a diabetic to purposely eat a ton of sugar and carbs to the point of going into a coma (which may kill him), just to prove he has diabetes? Of course not, he'd rightfully be sued with malpractice. I don't think telling somebody who gets violent reactions to gluten to go back on it to destroy their villi again, making sure that person gets malnourished just to satisfy his curiosity is every bit as bad. It could also kill you, and I am NOT exaggerating.

Now I have had the endoscopy I shall try the diet. I certainly won't let the biopsy results determine whether I give the diet a chance.

      Knowing what to do when feeling unwell.

      By Me,Sue · Posted

      I was diagnosed with coeliac disease a couple of years ago [ish]. I love my food and a variety of food, so it's been hard, as it is with everyone. I try and ensure everything I eat doesn't contain gluten, but occasionally I think something must have got through that has gluten in. Mainly I know because I have to dash to the loo, but recently I have noticed that I feel nauseous after possibly being glutened. I think the thing that I have got better at is knowing what to do when I feel wiped out after a gluten 'episode'. I drink loads of water, and have just started drinking peppermint tea. I also have rehydration powders to drink. I don't feel like eating much, but eventually feel like I need to eat. Gluten free flapjacks, or gluten free cereal, or a small gluten free kids meal are my go to. I am retired, so luckily I can rest, sometimes even going to bed when nothing else works. So I feel that I am getting better at knowing how to try and get back on track. I am also trying to stick to a simpler menu and eat mostly at home so that I can be more confident about what I am eating. THANKS TO THOSE WHO REPLIED ABOUT THE NAUSEA .

      The Happy Tart review

      Thanks. Since the back and forth and promises of review and general stalling went on for more than six months, the credit company will no longer investigate. They have a cutoff of maybe six months.

      The Happy Tart review

      By Scott Adams · Posted

      Is this the same restaurant? https://www.facebook.com/TheHappyTartFallsChurch/ Is it too late to take this up with your credit card company? Normally you have a few months to do a chargeback with them. It seems very odd that they are taking this approach with someone who is likely to be a regular customer--not a good business-minded way of handling things!

      Stomach burning and neuropathy

      By Scott Adams · Posted

      Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal. This article may be helpful: The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs. Because of this it took me decades to overcome a few long-standing issues I had that were associated with gluten ataxia, for example numbness and tingling in my feet, and muscle knots--especially in my shoulders an neck. Only long term extensive supplementation has helped me to resolve these issues.

      Nausea

      By Scott Adams · Posted

      Welcome to the forum. Is the nausea associated with eating certain foods, or anything else in particular?  Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy.
