Am exactly where you are. Weight loss, loose foul smelling pale stools and alot of gas. The gas is so much that I have flatal incontinence. It passes out without my knowledge and this is what has brought my life to a standstill.
Tests so far stool culture is OK, colonoscopy is OK, liver is OK, pancreas is OK, ESR is OK, blood sugar is ok, thyroid is OK. But the problem persists. I Don't drink at all and I've quit smoking since this started months ago.
What could be my problem. Am in Africa
Hopefully the CT scan will show something. Also ask him about the colonoscopy, did he get into the small bowel? If this continues and tests come back negative ask for blood work that would show if you have the crohns gene.
And don't worry, even if it were to be crohns or something like that, it sounds like it is very mild. But may be starting to flare. There are antibiotics for the flare-ups.

Your GI doc sounds like he's on top of this. I know this is scary and frustrating-- I feel the same way with my similar problem. But all you can do is keep at it. If your GI doc is running out of ideas, absolutely get a second opinion. What can it hurt?
