Doc says ibs. i have had mre small bowel, ct scan with vein contrast, colonoscopy, blood tests. all were normal. what are the chances i have crohns?

Very low: If all the above were normal including colonoscopy and colon biopsies then your chances of having crohn's is very slim. New evidence points to fructose and high fructose corn syrup as the culprit in ibs. Try to avoid the for few weeks and see.

Zero: If all tests and colonoscopy normal. Ibs is most commonly caused by poor diet affecting the lower brain that sends action signals to the bowel. Commonest cause is sugary "junk" food and beverages.

Dr Chao and another doctor agreed
