Sharon Successfully Treats Keto Rash with Carbs

Sharon shared her experience on Keto Rash Facebook Community and described how she tried many things unsuccessfully before finally increasing her carbs to treat her keto rash

Hi everyone.

I’ve been reading up on other instances of Keto rash wherever I can find it on the Internet and just thought I would share my experience. I have had a rash on and off on my arms for the past 3 years or so. It would appear and last for months at a time and then go away seemingly on its own.… Read More

Relationship Between Gut Biome and Keto Rash?

Recently posted in the Forums, a reader with keto rash wonders if there is a connection with a stool analysis that was done previously.

Hi Philip,

Thanks for your website – it’s good to know I’m not the only one that has suffered. I too get a rash when I embark on a high fat, low carb diet. It’s happened to me at least twice now and usually comes on about 1.5 weeks or so into the change in diet. For me it starts in my arm pits and then spreads across my trunk, although my skin as a whole feels very hot/irritated.

Melanie’s Keto Rash Experience

Melanie

Reader Melanie was kind enough to allow me to share her experience with the keto rash.  She also sent me a photo of her rash that she gave me permission to share.

Thank you for this blog! I just started a strict keto diet about 3 weeks ago and got the rash about 5 days ago. It started small and then spread into a pretty symmetrical rash all over my sides, lower torso, and mid back in two patches. The itch is making me crazy! It was only minimally calmed by hydrocortisone and calamine.

Keto Rash in 49 Koreans

Keto Rash in 49 KoreansNow 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

Prurigo Pigmentosa vs Confluent and Reticulated Papillomatosis

Prurigo Pigmentosa and CARP

This is just a letter to the editor in the Journal of the American Academy of Dermatology reporting a single case published in 2013.

Is prurigo pigmentosa an inflammatory version of confluent and reticulated papillomatosis?

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

Prurigo Pigmentosa: Report of two cases in the United States and review of the literature

Published in the Dermatology Online Journal December 2011

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 next article is also hot off the presses, published July/August 2014 in Pediatric Dermatology.

Segmental Prurigo Pigmentosa

This was simply a case report about a 13 year old girl (pictured above) who developed the rash.  Unfortunately they do not discuss what they think caused it.

They thought this was worthy of report primarily because of the distribution of the rash which they call “segmental,” describing how it appears almost as a band on the left side of her chest.… Read More
