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.

      Taking Probiotics but Still Getting Sick After Gluten – Advice?

      By Xravith · Posted

      Yes, you are right. Indeed, I’ve been feeling anemic since the beginning of this week, and today I felt horrible during a lecture at the university, I was trembling a lot and felt all my body incredibly heavy, so I had to come back home. I’ll do a blood test tomorrow, but I’m just worried about the possibility of it coming back negative. I’ve been eating two cookies in the morning as my only source of gluten over the past two weeks—could that affect the final result?

      New (possible) celiac diagnosis

      By trents · Posted

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      New (possible) celiac diagnosis

      By Judy M · Posted

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      Patiently Waiting to See Results

      By Scott Adams · Posted

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      Gluten free beer ?

      By Scott Adams · Posted

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.
