I am a 36 year old female who recently had a sigmoid colectomy. It was suppose to be laparoscopic, unfortunately during surgery the surgeon decided to open me up from belly button down. Thank God I haven't had any problems with the incision, with exception of a little tenderness every once in a while. I am now 6 weeks post op. After week three my Dr. placed me on a high fiber diet, which made my bowels move 5 - 7 times a day. (which is wonderful after not being able to have a normal bowel movement prior to surgery, due to a twisted colon). My BMs were healthy "looking" as far as size and color. Within the last week I've had bad cramping which comes and goes. Now my Stool is thin and the color is slowly fading to a dull tan color. I feel the urge to go but it's usually mostly gas. Should I be concerned that there may be some type of obstruction that is causing the thin stool?
