Yes. Patients may go to the doctor complaining of bloating or gas without abdominal pain and with normal bowel habits and still be diagnosed with IBS. However, if you have abdominal pain but your bowel movements are okay, that is not IBS and could be simple constipation or diarrhea. IBS is a group of symptoms, and all of those symptoms must be present to make a diagnosis of IBS. It is very important to make sure that your doctor has thoroughly looked at your symptoms because you could have a more serious condition that is being overlooked.
