l have had the scope done 2 years ago. Nothing was found but a long colon and knotted up intestines because he said worry!! l am 68 years old..I talked with my gastrogist and she said it is passing what you put in. But there are days l thought l was eating pretty good. Did not pass anything today but gas. Which yesterday l was not eating so well. l understand you do not pass anthing if there is not anything. l had the ct scan and really did not pass the solution they gave me for the test. I do have IBS and trouble with constiptation. She recommended me take Benefiber or Metimucil. She said if you do not eat a lot it is not going to pass a lot. l did take the linezz 290 to. But the benfiber and metimucil should l really be taking this?? She said also it will soften the stools. Thank you so very much for any replies and Thank you for listening to me and asking so many questions. l have never understood IBS much less why do l worry so??
