Dh Reaction Question

Hi,

I was wondering if someone with DH could share their experiences with skin reactions after gluten exposure. Here's a little background: Celiac runs in our family but we all tested negative. I've been gluten free for about 4 months b/c my children are gluten-free due to other non-celiac issues. I didn't get biopsied but noticed since going gluten-free a rash on my knees and elbows has completely gone away. It wasn't the typical DH type of rash--and it never bothered me--so it surprised me when it cleared up. I'd had it since I was a kid, and I'm now 37.

Well, funny thing, the past 2 weeks I've had gluten a couple times (since I don't think I have a medical necessity) and I've had several blister type of rashes (Look like poison ivy but it's not) come up on the inside of my foot. They seemed to happen 12 hours after eating gluten. I abstained from glutenous food for 3 days and had some again today, and sure enough the blister is back up and swolen. The bump is severely itchy and small, but doesn't spread. Is it possible that consuming gluten can cause a DH type of rash so soon after exposure?

Many thanks for any info you can share.

Yes. When I was newly diagnosed DH breakouts would occur within a few hours of exposure. If you want to have it checked to see if it is DH for sure then a trip to a derm would be in order. Make sure the derm understands the biopsy procedure, he would need to biopsy the tissue next to the lesion to look for antibodies in the surrounding skin. A positive biopsy for DH is a diagnosis of celiac, you would need no more testing for celiac diagnosis after that.

Thanks so much for your reply. Is it common to get a rash on inside of foot? I've read a lot about legs and arms, but not foot. I plan to make a derm appt. Will I have to have rash active for the area to be biopsied? Also, should I be on gluten foods at the time or doesn't it matter? I've been gluten-free for 4 months except a few times.

      Bitters for digestion?

      By AnnaNZ · Posted

      I forgot to mention my suspicion of the high amount of glyphosate allowed to be used on wheat in USA and NZ and Australia. My weight was 69kg mid-2023, I went down to 60kg in March 2024 and now hover around 63kg (just after winter here in NZ) - wheat-free and very low alcohol consumption.

      Hi Jess Thanks so much for your response and apologies for the long delay in answering. I think I must have been waiting for something to happen before I replied and unfortunately it fell off the radar... I have had an upper endoscopy and colonoscopy in the meantime (which revealed 'minor' issues only). Yes I do think histamine intolerance is one of the problems. I have been lowering my histamine intake and feeling a lot better. And I do think it is the liver which is giving the pain. I am currently taking zinc (I have had three low zinc tests now), magnesium, B complex, vitamin E and a calcium/Vitamin C mix. I consciously think about getting vitamin D outside. (Maybe I should have my vitamin D re-tested now...) I am still 100% gluten-free. My current thoughts on the cause of the problems is some, if not all, of the following: Genetically low zinc uptake, lack of vitamin D, wine drinking (alcohol/sulphites), covid, immune depletion, gastroparesis, dysbiosis, leaky gut, inability to process certain foods I am so much better than late 2023 so feel very positive 🙂

      4.5 years into diagnosis, eating gluten-free and still struggling: would love support, tips, & stories

      Hi and thank you very much for your detailed response! I am so glad that the protocol worked so well for you and helped you to get your health back on track. I've heard of it helping other people too. One question I have is how did you maintain your weight on this diet? I really rely on nuts and rice to keep me at a steady weight because I tend to lose weight quickly and am having a hard time envisioning how to make it work, especially when not being able to eat things like nuts and avocados. In case you have any input, woud be great to hear it! Friendly greetings.

      Is this celiac?

      By Hmart · Posted

      I was not taking any medications previous to this. I was a healthy 49 yo with some mild stomach discomfort. I noticed the onset of tinnitus earlier this year and I had Covid at the end of June. My first ‘flare-up’ with these symptoms was in August and I was eating gluten like normal. I had another flare-up in September and then got an upper endo at the end of September that showed possible celiac. My blood test came a week later. While I didn’t stop eating gluten before I had the blood test, I had cut back on food and gluten both. I had a flare-up with this symptoms after one week of gluten free but wasn’t being crazy careful. Then I had another flare-up this week. I think it might have been caused by Trader Joe’s baked tofu which I didn’t realize had wheat. But I don’t know if these flare-ups are caused by gluten or if there’s something else going on. I am food journaling and tracking all symptoms. I have lost 7 pounds in the last 10 days.

      Welcome to the forum, @Hmart! There are other medical conditions besides celiac disease that can cause villous atrophy as well as some medications and for some people, the dairy protein casein. So, your question is a valid one. Especially in view of the fact that your antibody testing was negative, though there are also some seronegative celiacs. So, do you get reactions every time you consume gluten? If you were to purposely consume a slice of bread would you be certain to develop the symptoms you describe?
