Ernährung bei Lichen Sclerosus. Gibt es eine bestimmte Ernährungsweise, die die Lebensqualität einer Person mit Lichen Sclerosus verbessert?

Yes absolutely. In my case and in many others that I know of processed sugars, gluten (wheat) and for some dairy products are definitely a cause for a 'flare'. In my case I can eat dairy without a problem. Drinking plenty of water is also beneficial. It can be very hard to cut these out but initially you need to be quite hard and gradually reintroduce things to see what your own tolerance level is .... LS is not a 'one size fits all' disease.
