I am having very soft, floating, foul smelling stools, very foul flatus, bloating, belching and general abdominal discomfort. My gastroenterologist has had me on creon and probiotics for 2 months with no improvement. I ve been treated for H pylori. I added lactaid and greatly reduced gluten in my diet. No relief yet. Negative abdominal ultrasound and c.t . Scan. At times I have precipitous diarrhea incontinently. I cannot control the flatus. I had gastric bypass surgery a year ago and have lost 117 pounds. I am almost too thin now at 120 pounds and 5 2 tall. What else could this be? What should I be doing?
