Maybe your aunt is confused and he did a colonoscopy and an endoscopy. The colonoscopy is the large intestine. Celiac destroys the villi in the small intestine. The endo goes in thru the mouth for the top part. Taking biopsies during the endo is how they diagnose Celiac. I had both done just to make sure I didn't have anything going on in the second half, too.

Hopefully, the doc isn't the confused one. Sometimes people hear " oscopy" and they all sound the same.

You cannot test for Celiac with a colonoscopy. It's done with an endoscopy.

They biopsy the small intestines. You will get a negative test every time with a colonoscopy.

The damage to the villi caused by celiac disease cannot be detected by colonoscopy. An endoscopy of the duodenum is needed to do that.

Is it possible that both an endoscopy and a colonoscopy were done at the same time? The preparation for a colonoscopy is more involved and includes what is needed for the endoscopy. It is prudent to do both, as there may be other issues besides celiac disease.

I have had the double procedure twice. In 2000, the endoscopy showed severe damage to my villi, while the colonoscopy was normal. When repeated in 2005, my villi were completely healed and were normal.

Thats what I thought. I need to ask. I hope it's not the doctor that is confused. I'd get another doc. Thanks guys. :D

Your aunts gastro can't look for celiac in the large intestine with a colonoscopy. She would need an endoscopy to find damage to the villi in the small intestine. My mother-in-law said her doc told her she didn't have celiac after her colonoscopy too but if he did, he is unclear on how celiac is diagnosed. Glad we use a different gastro than she does!

If your aunt's gastro did check with a colonoscopy, she also doesn't know how and where to check for celiac and any diagnosis based on that would be irrelevant.

      Terrible Neurological Symptoms

      Thiamine Mononitrate is "shelf stable" and won't break down easily when exposed to heat, light and over time. This makes it very hard for the body to absorb and utilize it. Only thirty percent is absorbed, less is utilized because it takes additional thiamine to break it down. Thiamine Hydrochloride is great. Benfotiamine is wonderful, too. Retaining...

      @Known1, Search for "niacin flush fades the longer you use it" and "Niacin flush worse if deficient". It takes a couple to three weeks for the body to adjust and you're at that point now, so things should improve. Riboflavin makes the neon color, which glows under black light. If not absorbed, excreted. Absorption of riboflavin will improve...

      Terrible Neurological Symptoms

      The conversion factor for mg/dl and mmol/L is 18. So 5 = 90, 7 = 126, and so on. In the US, blood sugar regulations now are the same as what we use in the UK except for this difference in units. In terms of how they compare in the past, the numbers today that I quoted are stricter than they used to be. Blood sugar numbers for +1 and +2 hour postprandial are...

      @knitty kitty For me, the flushing lasts about 10 hours and not just 60-90 minutes after consuming the vitamins. I am 10-days into taking this already. My urine is neon colored around the clock and I drink between 1/2 to 3/4 of a gallon of water per day. I'll stick with 2 a day for now, but am honestly quite hesitant to do so. I am curious, where...

      Terrible Neurological Symptoms

      Thiamine Mononitrate is "shelf stable" and won't break down easily when exposed to heat, light and over time.  This makes it very hard for the body to absorb and utilize it.  Only thirty percent is absorbed, less is utilized because it takes additional thiamine to break it down.   Thiamine Hydrochloride is great.  Benfotiamine is wonderful, too.   Retaining water, edema, is a symptom of low thiamine.  I'd bloat up like a puffer fish.   The ingrown toenail problems I had that I attribute to Niacin deficiency and Vitamin C deficiency.  My toenails curled in and grew thick and yellow, thickened heels.  It was awful.   So glad you're going to give thiamine hydrochloride a try!   Let me know how it goes.  You may feel worse before you feel better, the thiamine paradox, but it does clear up.  It's like a car back firing if it hasn't been run for a while.   Thiamine and benfotiamine: Focus on their therapeutic potential https://pmc.ncbi.nlm.nih.gov/articles/PMC10682628/

Riboflavin makes the neon color, which glows under black light.  If not absorbed, excreted.  Absorption of riboflavin will improve as the body starts healing the intestinal lining and villi grow back.   You could skip the multivitamin instead.

      The conversion factor for mg/dl and mmol/L is 18. So 5 = 90, 7 = 126, and so on. In the US, blood sugar regulations now are the same as what we use in the UK except for this difference in units. In terms of how they compare in the past, the numbers today that I quoted are stricter than they used to be. Blood sugar numbers for +1 and +2 hour postprandial are measured from the beginning of a meal in these official numbers. In regards to the thiamin supplement I have: it says it is thiamine mononitrate. I had not until now been aware there were different types (it seems I find that is the case with everything, including the magnesium I take!) and this one I have is the only one available in my local stores. I know it makes my pee smell strong when I take it which would seem to indicate my body is absorbing enough that the remainder gets ejected, but I could be wrong. Of course, I'm willing to try anything reasonable to correct this long standing condition, whatever it might be so I will try and get thiamin hydrochloride. Back on the note of diabetes (potentially) I haven't had the blood test for a while and I did notice ingrown toenail type infections a few times in the last 3 years that kept coming back. I heard that diabetes caused high urination. But eating sugar and elevated blood sugar causes the opposite in me. If I eat a lot of sugar I retain water, like big time. If I ate a bunch o sugar in the afternoon say, I can produce little enough urine that I can go over 12 hours and have nowhere near enough urine to need to void in that time or longer which seems abnormal.

I am curious, where are you reading "the worse the flush, the more your body needs the niacin"?  I have been searching for that, but haven't found that anywhere.
