I just read comments from the lichen planus group and one or two ladies stressed diet is as a very important consideration for treating lichen planus. One claimed dramatic improvements after following diet that sounds like the SIBO diet, which is highly restrictive. I tried that diet a few years ago for SIBO and was hungry most of the time because 80% of the food I ate was prohibited. I spent hours every week on meal planning and shopping . Also lost 13 pounds in the first month that I didn't need to lose and still have sagging skin as a result. After a year I eventually began eating "normally" again. I am very curious if anyone who reads this has had noticeable improvements in her lichen sclerosus or planus by eliminating sugar, gluten , alcohol, etc, etc. ?
