While I am not and have never been on dialysis I know a lot of people that have been. I have been researching how sweat might be used to be an adjunctive treatment for or delay progression of kidney failure. I was convinced enough that I started a company that is looking to scientifically evaluate whether this is true. There are found a few trials, some others have mentioned on this site, and they all had positive results. The citations are on my company's website
http://www.ThirdKidney.net.. I have also read many of the posts on this website and know that there are promotors and detractors, some who even use sweat based therapies. My rationale - Let's do quality research and find out.
I would encourage you to visit our website and look at the science. There is an article that I recently authored that was published in a peer reviewed international journal using a rat model of renal failure. The project was funded by the American Society of Nephrology. If there is enough popular demand we would likely be able to post the research articles to the website and have discussions about them. A sort of "virtual journal club."
We can't recruit people for studies yet, but are actively fundraising to be able to get things started. If you want to donate you can visit
