Re: 15 year old son has abdominal pain, rectal bleeding & losing weight
As you know, it could be many things.. the symptoms sound like Crohn's or Ulcerated Colitis. The endoscopy should show any inflammation. I hope they do a colonoscopy too.
Once he is diagnosed with either of those, the medication usually works pretty well for it. After my first bout (everything was normal too, except the colonoscopy - last test) it took about 2 weeks to feel OK and after a month on the medication I was feeling back to normal.
