I've suffered from dermatitis on and off since childhood and have had to use emollients daily for the past 4 years or so.
at the beginning of this year I went vegetarian and spent about 6 weeks following a vegan diet.
My dermatitis cleared up and I had no itching.
When I reintroduced dairy I found that whenever I had ice cream I would have diarrhoea within a couple of hours and dreadful stinky wind (sorry if tmi). My skin would also get itchy in the areas I had the dermatitis.
I also seem to be affected to a lesser extent by milk but OK with a small amount of chocolate, yoghurt and cheese/butter.
could it be lactose intolerance or something else? Could I have brought it on by going vegan? Should I see a GP or just eliminate the problem foods from my diet?
