Gastro-intestinal Issues (autism)

Hi Everyone,

I have a friend who is autistic and he has had gastro-intestinal issues his whole life, or as far back as he can remember anyway and he is awaiting a colonoscopy. I am also autistic and have had my own issues with this too. I have been reading different studies and scientific research online and have found that there may be a link between autism and bowel problems. I know from personal experience that all the autistic people I have encountered in my life have had a lot of bowel and tummy problems from a young age. I wonder if any of you have had a similar experience or have managed to resolve these issues in your self and what tips you may have to ease this? Hopefully more research is done on autism's connection to gastro-intestinal problems instead of research money going towards trying to invent cures using old drugs like Suramin for example.

Hope everyone has a good week.
