Has your son officially been diagnosed with UC...if yes, he has UC. Yes, it could have been set in motion at an early age, possibly with very minimal inflammation continuing throughout his life. If he suffered through lots of constipation or bouts of diarrhea, it could have been UC and IBS..
How old is your son? You might consider to make a signature with some of that information so that it's clear for us reading your posts.
How is he doing at this time?.
