Last September after a trip to the mountains I began to have a complete change in bowel habits and had either diarrhea or soft, unformed stool. I was checked for parasites, bacteria, etc in late October and everything was normal. I made an appointment with the physician who had done my previous colonoscopy and asked him if it should be repeated. He said no because I had no real pain and no abnormal lab work.In the last two months I moved 1500 miles to begin a new job and I was very stressed-out by the change. I am not as stressed now, but my loose stool has become constipation and bloating...with narrow stools, small volumes, and straining to go. Also, I now have diffuse upper ab pain.The doctor here has checked everything...myriad blood work, ultrasound, barium CT with contrast dye and all is normal. Thus, she has suggested I have IBS.My question is this...so what do I do about the constipation? I used an enema the other night, which helped, and I am now on miralax and fiber. After two days on the laxative, however, nothing much is happening. Does anyone have any advice???Thanks!
