my blood test came back positive for gluten sensitivity. however, my biopsy from my colonoscopy and endoscopy were negative for gluten. how is this possible? could i have a mild form of celiac? i've been suffering from severe canker sores for over a few years now. my oral pathologist wants me to go on a gluten-free diet anyways and see what happens. any feedback?

I have heard of this happening and also vice versa. Basically in my opinion the reason your endoscopy / biopsy was negative could be because of 2 reasons:

1. the gluten has not had time to damage the villi in your small intestines (which is good)

2. the part of the small intestines in which was biopsied was not damaged. I've heard that docs should get 5-10 biopsies to check, all in different areas. Also it could have shown "patchy inflammation" and your doc was not concerned with it (that is what happened to me).

If your blood work was positive then you should be on a strict gluten free diet for the rest of your life.

Good luck to you

Who interpreted your biopsy? The doctor or the lab? I found out recently that sometimes the lab doctors aren't as good at interpreting Celiacs as the actual GI doctor. Basically, your GI could interpret the pictures and tissue samples differently. This just happened to me. Did you GI actually look all all of the slides himself or did he just go by the pathology report?

Others have already explained how this can happen. Believe me, it's not unusual to have positive blood test and negative biopsy. The positive blood test alone makes it almost certain you have it because false positives are rare.

Canker sores was one of my main symptoms but I never knew what was causing them. They completely disappeared on the gluten-free diet. I NEVER have them any more. It was very astute of your doctor to pick up on celiac disease as a possible cause. Personally, I would go gluten-free.

Defenitly go gluten-free!!!!!!!!!! The blood is telling you that you have this disease and if you have problems that going gluten-free would clear up, you don't need a biopsy to prove that.

I also have had positive IGA and IGG results and a negative biopsy. At the time of my biopsy I was on budesoniod ( a steriod used to treate crohns disease) and according to my doctor it can also be used to treate celiacs. My doctor had forgotten that I was still on budesoniod at the time of the biopsy and thought the budesoniod had masked any damage. After being off of the budesonoid for a month I was retested for the IGA and IGG antibodies and they are still above normal and had increased (IGA- 44, IGG-110) since my last test. Has anyone heard anything about different medicines used to treate Celiacs or if they have had any effect on biopsy results? I am also on 6mp (Purinthol) and Pentasa for Crohns disease. Right now, my doctor wants me to go on a three month gluten free trial and see if my numbers go down.

      IBS-D vs Celiac

      No coincidence. Recent revisions to gluten challenge guidelines call for the daily consumption of at least 10g of gluten (about the amount in 4-6 slices of wheat bread) for a minimum of 3 weeks. If possible, I would extend that two weeks to ensure valid testing.

      IBS-D vs Celiac

      Thank you both for the replies. I decided to bring back gluten so I can do the blood test. Today is Day #2 of the Challenge. Yesterday I had about 3 slices of whole wheat bread and I woke up with urgent diarrhea this morning. It was orange, sandy and had the distinctive smell that I did not have when I was briefly gluten free. I don't know if it's a...

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      @Jane02, I hear you about the kale and collard greens. I don't do dairy and must eat green leafies, too, to get sufficient calcium. I must be very careful because some calcium supplements are made from ground up crustacean shells. When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly. This is safe...

      Hello, @Jane02, I take Naturewise D 3. It contains olive oil. Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets. Fractionated coconut oil is not the same as coconut oil used for cooking. Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the...

      @Jane02, I hear you about the kale and collard greens.  I don't do dairy and must eat green leafies, too, to get sufficient calcium.  I must be very careful because some calcium supplements are made from ground up crustacean shells.  When I was deficient in Vitamin D, I took high doses of Vitamin D to correct the deficiency quickly.  This is safe and nontoxic.  Vitamin D level should be above 70 nmol/L.  Lifeguards and indigenous Pacific Islanders typically have levels between 80-100 nmol/L.   Levels lower than this are based on amount needed to prevent disease like rickets and osteomalacia. We need more thiamine when we're physically ill, emotionally and mentally stressed, and if we exercise like an athlete or laborer.  We need more thiamine if we eat a diet high in simple carbohydrates.  For every 500 kcal of carbohydrates, we need 500-1000 mg more of thiamine to process the carbs into energy.  If there's insufficient thiamine the carbs get stored as fat.  Again, recommended levels set for thiamine are based on minimum amounts needed to prevent disease.  This is often not adequate for optimum health, nor sufficient for people with absorption problems such as Celiac disease.  Gluten free processed foods are not enriched with vitamins like their gluten containing counterparts.  Adding a B Complex and additional thiamine improves health for Celiacs.  Thiamine is safe and nontoxic even in high doses.  Thiamine helps the mitochondria in cells to function.  Thiamine interacts with each of the other B vitamins.  They are all water soluble and easily excreted if not needed. Interesting Reading: Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/ Safety and effectiveness of vitamin D mega-dose: A systematic review https://pubmed.ncbi.nlm.nih.gov/34857184/ High dose dietary vitamin D allocates surplus calories to muscle and growth instead of fat via modulation of myostatin and leptin signaling https://pubmed.ncbi.nlm.nih.gov/38766160/ Safety of High-Dose Vitamin D Supplementation: Secondary Analysis of a Randomized Controlled Trial https://pubmed.ncbi.nlm.nih.gov/31746327/ Vitamins and Celiac Disease: Beyond Vitamin D https://pmc.ncbi.nlm.nih.gov/articles/PMC11857425/ Investigating the therapeutic potential of tryptophan and vitamin A in modulating immune responses in celiac disease: an experimental study https://pubmed.ncbi.nlm.nih.gov/40178602/ Investigating the Impact of Vitamin A and Amino Acids on Immune Responses in Celiac Disease Patients https://pmc.ncbi.nlm.nih.gov/articles/PMC10814138/

      Thank you so much @knitty kitty for this insightful information! I would have never considered fractionated coconut oil to be a potential source of GI upset. I will consider all the info you shared. Very interesting about the Thiamine deficiency.  I've tracked daily averages of my intake in a nutrition software. The only nutrient I can't consistently meet from my diet is vitamin D. Calcium is a hit and miss as I rely on vegetables, dark leafy greens as a major source, for my calcium intake. I'm able to meet it when I either eat or juice a bundle of kale or collard greens daily haha. My thiamine intake is roughly 120% of my needs, although I do recognize that I may not be absorbing all of these nutrients consistently with intermittent unintentional exposures to gluten.  My vitamin A intake is roughly 900% (~6400 mcg/d) of my needs as I eat a lot of sweet potato, although since it's plant-derived vitamin A (beta-carotene) apparently it's not likely to cause toxicity.  Thanks again!

      Hello, @Jane02,  I take Naturewise D 3.  It contains olive oil.   Some Vitamin D supplements, like D Drops, are made with fractionated coconut oil which can cause digestive upsets.  Fractionated coconut oil is not the same as coconut oil used for cooking.  Fractionated coconut oil has been treated for longer shelf life, so it won't go bad in the jar, and thus may be irritating to the digestive system. I avoid supplements made with soy because many people with Celiac Disease also react to soy.  Mixed tocopherols, an ingredient in Thornes Vitamin D, may be sourced from soy oil.  Kirkland's has soy on its ingredient list. I avoid things that might contain or be exposed to crustaceans, like Metagenics says on its label.  I have a crustacean/shellfish/fish allergy.  I like Life Extension Bioactive Complete B Complex.  I take additional Thiamine B 1 in the form Benfotiamine which helps the intestines heal, Life Extension MegaBenfotiamine. Thiamine is needed to activate Vitamin D.   Low thiamine can make one feel like they are getting glutened after a meal containing lots of simple carbohydrates like white rice, or processed gluten free foods like cookies and pasta.   It's rare to have a single vitamin deficiency.  The water soluble B Complex vitamins should be supplemented together with additional Thiamine in the form Benfotiamine and Thiamine TTFD (tetrahydrofurfuryl disulfide) to correct subclinical deficiencies that don't show up on blood tests.  These are subclinical deficiencies within organs and tissues.  Blood is a transportation system.  The body will deplete tissues and organs in order to keep a supply of thiamine in the bloodstream going to the brain and heart.   If you're low in Vitamin D, you may well be low in other fat soluble vitamins like Vitamin A and Vitamin K. Have you seen a dietician?
