Since last year, my 16 years old autistic daughter is having this kind of eating disorder. She always throw up after having meals. A month later........I was able to stop her that habit and since then......it's almost a year now she has this kind of rumination syndrome. Ofcourse she never been officially diagnosed for there's no good doctor here in Japan. She now lost more than 22 pounds. Don't really know what would be my next step to do. But I'm glad I found this page and also finally found out what's going on with her.
