[Editor’s Note: This is a guest post from a visitor of the site who wants to go by Jude. I think its wonderful for folks who have the keto rash to share their experiences for the benefit of others. We all know how little information there is out there regarding this, so the more cases we can accumulate the better. Please, if you think this is something you have, I’d encourage you to share your experiences here. Many of you have done so already in the comments section, which is fantastic. … Read More

Every once in a while people will contact me about a rash that they think might be keto-rash. I do my best to respond to all of them, and sometime I hear back and sometimes I don’t. Well here’s a case where someone with a rash tried treating it by increasing their carb intake and provided wonderful followup.
In early December I received this e-mail from a visitor named Apryl:

“I found this page by Googling “low carb diet rash”… after breaking out into a rash under my breast and rib cage area.
In a few of the papers I’ve read, some authors have expressed the notion that ketone bodies can actually cause inflammation, and this may be an explanation for why the keto rash occurs.
Most recently I read this in the study looking at prurigo pigmentosa in 50 koreans:
Like I mentioned before, this idea really piqued my curiosity so I headed on over to the references and saw:
Now this may sound familiar, especially since I just wrote a post on another study where they analyzed the keto rash in 50 koreans, and I myself had to do a double take because this was published in the same year as the other study… but after reading the paper itself, I can reassure that it is a completely separate study. While the country is the same, the authors are different, the journal is different, and the patients are different (although there may be some overlap, I’ll explain why).… Read More
This is just a letter to the editor in the Journal of the American Academy of Dermatology reporting a single case published in 2013.
The case was of a 24 year old white male with a 2 week history of itchy rash on his back, chest, and abdomen.
He was first treated with both oral and topical corticosteroids to no effect. A skin biopsy was performed and he was diagnosed with prurigo pigmentosa.
Unfortunately they do not go into potential causes of the rash in this patient (ie fasting, dieting, weight loss, etc.), but since this is a letter to the editor, it’s not subject to the same scientific rigor as regular journal articles.… Read More
In the comments section of the BJJ Caveman keto rash page a reader named John wrote:

I had no reoccurrence of the rash after taking Doxycycline for 11 days without any change in my diet 9 months ago (see above and be aware of rare but possible severe side effects affecting mood). In order to avoid antibiotic-associated diarrhea I took Saccharomyces boulardii together with the antibiotic.
I now do intermittent fasting daily throughout the work-week without any problems. My longest fast was 36 hours.
Maybe Doxycycline wipes out certain types of gut bacteria that can proliferate extremely well under the conditions of ketosis, but not otherwise and produce a substance that causes the rash.
Dave Asprey, the Bulletproof Executive briefly discussed his thoughts on the keto rash in his most recent Q&A session.
Before going into this, I want to first thank Jasmine from jasminesvision.com for alerting me to this a few weeks ago.
Beginning at the 41:50 mark they address the question of:
“What are your thoughts on Keto rash and it’s causes or processes. It’s not everyone, so why some and not the others. Is that genetic? And is the only cure carb consumption. It would seem as though waiting it out as if it were a detoxing mechanism is risky, as it can cause scarring.”

I actually really feel terrible for the first patient because she had this rash off and on for 2 years and underwent multiple skin biopsies… which led to her being misdiagnosed with herpes simplex virus for which she was treated unsuccessfully with anti-viral medications (oral acyclovir, valcyclovir, and topical acyclovir) as well as topical corticosteroids with no improvement.… Read More
This is a great paper with one of the largest series of keto rash cases assembled to date. They also do a wonderful job going into the history of the rash, and is probably the most comprehensive paper available. Let’s dive in!
Published in 2012, in the Journal of Dermatology
They report that this rash was first described in Japan, in 1971 (can’t wait to look at this paper), with more than 300 cases reported at the time of this papers publication.… Read More
NOTE: A version of this was originally published on bjjcaveman.com (here) on September 5, 2014.
This was another paper that caught my attention because of the title which identified a specific organism in the skin biopsy of the prurigo pigmentosa rash.
This was published in the American Journal of Dermatopathology on June of 2012.
This was a 23 year old Chinese man with a history of rash for 3 years.
They performed a skin biopsy from which they were able to isolate the Helicobacter pylori organism. … Read More
