How Long Does It Take To Have A Dh Reaction?

I'm trying to figure out how long it takes for a possible gluten-ingestion to turn into a DH outbreak. Does anyone have a specific time they know of when they react to gluten through DH?

I've been having trouble with my DH spot (on my fingers and palms), and I don't know what's causing it. I cut out iodine salt last year, which (I think) made the outbreaks go away for several months. But it's back now.

I usually react rather quickly--within 30-60 minutes or so. However, the blisters form one by one over a period of days after I've accidentally ingested gluten. By any chance, do you take thyroid meds? If so, they contain iodine, and even the smallest ecposure to gluten will cause DH to recur.

I don't take thyroid meds, but I think I identified what happened...I drank some Rice Dream last Fri. and Sat. and the topic of that having barley traces in it just came up in the forum (coincidentally, since I've never had the stuff before). So I think that did it, but the DH troubles continued into yesterday, so I didn't know if it was something else too.

Can i ask a nieve question? what does iodine and thyroid medication have to do with DH? i'm new to the forum, i definitely have a gluten intolerance. i was tested for celiac sprue and was negative, but all signs show a sensitivity to gluten including DH.

Generally speaking it takes days for blisters to form. On average, it's slower than other celiac disease reactions. Of course everybody's different.

As for the iodine question, iodine can aggravate or trigger DH even though there's no gluten, but once you're completely gluten-free, it shouldn't cause problems. It never did cause any problems for me, but it has for others. If you're eating high-iodine items now and there's no problem, you don't need to worry.

I can flare up within 24 to 48 hrs. if I don't take my medication, Dapsone. I have a thyroid issue, which goes along with having DH. I also have celiac disease and just diagnosed with lymphocytic colitis. I have had DH for 40 yrs. and have been studied at Stanford & Univ of Utah. Gluten seems to be the enemy.

      Cristiana, that sounds like a great approach and I will be looking forward to the results. I am in the same boat as you. I don't experience overt symptoms with minor, cross contamination level exposures so I sometimes will indulge in those "processed on equipment that also processes wheat . . ." or items that don't specifically claim to be gluten free but...

      Increased intraepithelial lymphocytes after 10 yrs gluten-free

      I've been reflecting on this further. The lowest TTG I've ever managed was 4.5 (normal lab reading under 10). Since then it has gone up to 10. I am not happy with that. I can only explain this by the fact that I am eating out more these days and that's where I'm being 'glutened', but such small amounts that I only occasionally react. I...

      Low iron and vitamin d

      Hi, I posted before about my son's legs shaking after gluten. I did end up starting him on vit b and happily he actually started sleeping better and longer. Back to my 4 year old. She had gone back to meltdowns, early wakes, and exhaustion. We tested everything again and her ferritin was lowish again (16) and vit d was low. After a couple weeks...

I don't experience overt symptoms with minor, cross contamination level exposures so I sometimes will indulge in those "processed on equipment that also processes wheat . . ." or items that don't specifically claim to be gluten free but do not list gluten containing grains in their ingredient list. But I always wonder if I am still experiencing sub acute inflammatory reactions. I haven't had any celiac antibody blood work done since my diagnosis almost 25 years ago so I don't really have any data to go by.

I know some of it is also to do with eating products labelled 'may contain gluten' by mistake - which in the UK means it probably does! It stands to reason that as I am a coeliac any trace of gluten will cause a response in the gut.  My villi are healed and look healthy, but those lymphocytes are present because of the occasional trace amounts of gluten sneaking into my diet.   I am going to try not to eat out now until my next blood test in the autumn and read labels properly to avoid the may contain gluten products, and will then report back to see if it has helped!

      Low iron and vitamin d

      Hi, I posted before about my son's legs shaking after gluten. I did end up starting him on vit b and happily he actually started sleeping better and longer.  Back to my 4 year old. She had gone back to meltdowns, early wakes, and exhaustion. We tested everything again and her ferritin was lowish again (16) and vit d was low. After a couple weeks on supplements she is cheerful, sleeping better and looks better. The red rimmed eyes and dark circles are much better.   AND her Ttg was a 3!!!!!! So, we are crushing the gluten-free diet which is great. But WHY are her iron and vit d low if she's not getting any gluten????  She's on 30mg of iron per day and also a multivitamin and vit d supplement (per her dr). That helped her feel better quickly. But will she need supplements her whole life?? Or is there some other reason she's not absorbing iron? We eat very healthy with minimal processed food. Beef maybe 1x per week but plenty of other protein including eggs daily.  She also says her tummy hurts every single morning. That was before the iron (do not likely a side effect). Is that common with celiac?

      Celiac disease is the most likely cause, but here are articles about the other possible causes:
