For the past few yrs, when I feel I need a bowel movement, I can barely make it to the washroom. It only happens when I m home and normally in the morning after eating. I often feel naugeus off and on. Another symptom us when I eat certain things I get really bloated. I ve been tested for ceilac disease and came back negative. I had changed drs and was told that I had IBS without any testing. I recently has a colonoscopy , if I had IBS wouldn t that show??
