Help With A Gluten Challenge

In reading the forums it seems that people say you should eat gluten for 3 months before a biopsy if you have been gluten-free for awhile. Does anyone know of any research that supports that if you have only been gluten-free for 7 weeks? For a few reasons I decided it would be beneficial to look into an official diagnosis so I got a recommendation for a good doctor from some people my local celiac support group. I met with him today and he says gluten could be behind my issues so he'd like to do a complete celiac bloodwork (apparently the bloodwork I had done wasn't complete) and a endoscopy (he takes at least 12 biopsies). He said to go back on gluten for a couple of weeks. That conflicts with a lot of the info I see on this forum. I've looked online for research that supports being back on gluten for 3 months but haven't found much. Can anyone help me out? I was really impressed with this doctor so I'm not trying to prove him wrong, but I am just wanting to look into why others recommend 3 months so I can decide when to schedule this.

Yes, for a biopsy to have a chance to be positive for celiacs you need to consume gluten over time, so that, if you have it, the damage will be shown:(

Unfortenently, i was gluten free for 4 weeks before mine (which is the reason why i think i got a negative).

i dont have evidence on how long you should do it, but i can share with u- that i went on a 2 week gluten challenge- and it apparently was not enough, as my celiac panel looked almost identical to the 1st panel i did before the challenge

About seven weeks ago I attended a major lecture by one of Canada's leading celiac specialists who said you MUST go on gluten for at least three months, eating the equivalent of four pieces of bread a day. That is what my surgeon and dietitian told me as well. Sorry that I do not have any sources for you to read, though. I have handouts from the lecture so will check to see if there was an explanation for that timeframe.

I ate lots of gluten for nearly four months and definitely had positive biopsy results. :(

I scheduled it for 2 months from now. I can always push it back if I want to. They didn't seem to mind. The doctor said he's had success with a 2 week challenge but if I did that and it came back negative then I would always question it. Since the results of this could possibly affect some future career choices (whether I can work around gluten) I want to make sure I get an accurate result.

Here is part of where the three months came from on the board. I did some digging in the medical literature a while back when we were all confused by conflicting advice from doctors. Scroll down to the fourth post for the studies I found.

What I don't know is whether seven weeks is enough to switch to a normal biopsy. It's certainly enough to make an "iffy" antibody test negative.

Thanks for the info. I think I'll just continue with the gluten challenge until September and do the biopsy. School will be starting in a couple weeks and it's hard to get away those first few weeks anyway. I've also wondered if it was possible that my body could heal in just 7 weeks if I do have celiac. Seems like a lot of healing in just a fairly short period of time.

      Just wanted to add that checking B12 and Vitamin D only is not going to give an accurate picture of vitamin deficiencies.   B12 Cobalamine needs the seven other B vitamins to work properly.   You can have vitamin deficiency symptoms before the B12 blood level changes to show deficiency.  You can have "normal" B12, but have deficiencies in other B vitamins like Thiamine and Niacin, for which there are no accurate tests. Take a B Complex supplement with all the B vitamins.  Take additional Thiamine B 1 in the form Benfotiamine which has been shown to promote intestinal healing.  Thiamine Mononitrate found in most vitamin supplements is not easy for the body to utilize.  What makes thiamine mononitrate not break down on the shelf also makes it hard for the body to absorb and utilize.  Thiamine and Niacin B 3 deficiency symptoms include anxiety, depression and irritability.  The brain uses more Thiamine than other organs.  Take the B Complex and Thiamine in the form Benfotiamine or TTFD (tetrahydrofurfuryl disulfide) and look for health improvements in the following weeks.

      High DGP-A with normal IGA

      Hello, @rei.b, Ehlers Danlos syndrome and Celiac Disease can occur together in genetically predisposed individuals.  Losing ones gallbladder is common with celiac disease. I'm glad Naltrexone is helping with your pain.  Naltrexone is known to suppress tTg IgA and tTg IgG production, so it's not surprising that only your DGP IgG and DGP IgA are high.   Have you tried the Autoimmune Protocol diet designed by Dr. Sarah Ballantyne, a Celiac herself?  The AIP diet helps lower inflammation and promotes intestinal healing.   The AIP diet is a Paleo diet that eliminates foods that can cause intestinal inflammation until you heal on the inside, then more foods can be added back in.  The low histamine AIP diet will help reduce inflammation further.   Histamine is released as part of the immune response in celiac disease.  Foods also contain various amounts of histamine or provoke histamine release.  Lowering the amount of histamine from foods helps.  The body, with help from B vitamins, can clear histamine, but if more histamine is consumed than can be cleared, you can stay in an inflammatory state for a long time. Cutting out high histamine foods is beneficial.  Omit night shades which contain alkaloids that add to leaky gut syndrome found with celiac disease.  Night shades include tomatoes, peppers including bell peppers, potatoes and eggplants.  Processed foods like sausages and gluten-free processed products are high in histamines.  All Grains are removed from the diet because they are inflammatory and provoke histamine release. Blood tests for deficiencies in B vitamins are notoriously inaccurate.  You can have vitamin deficiency symptoms before blood levels show a deficiency.  Blood levels do not accurately measure the quantity of B vitamins stored inside the cells where they are utilized.  The brain will order stored vitamins to be released from organs into the blood stream to keep the brain and heart supplied while deficiency occurs inside organs, like the gallbladder.  Gall bladder dysfunction is caused by a deficiency in Thiamine Vitamin B 1 and other B vitamins.   The eight essential B vitamins are water soluble and easily lost with diarrhea and constipation, and the malabsorption and inflammation that occurs with celiac disease.  Because they are water soluble, the body can easily excrete any excess B vitamins in urine.  The best way to see if you are deficient is to take a B Complex and Thiamine in the form Benfotiamine and look for health improvements in the following weeks.  Most B Complex supplements contain Thiamine Mononitrate which is not bioavailable.  The body has a difficult time utilizing thiamine mononitrate because it doesn't break down easily.  Benfotiamine has been shown to promote intestinal healing.   Remember your intestines are in a damaged, permeable state.  Treat them tenderly, like you would a baby until they heal.  You wouldn't feed a baby spicy bell peppers and hard to digest corn and nuts.  Change your diet so your intestines can heal.   I use a combination of B12 Cobalamine, B 6 Pyridoxine, and B1 Benfotiamine for pain.  These three B vitamins have analgesic properties.  They relieve pain better than other otc pain relievers.

      I hadn't been eating gluten free before having the antibody test done. I started eating gluten free after having the test done because the gastro PA told me to eat gluten-free for 6 months. I'm now 3 months in.
