I'm new to WebMD because I am also looking for answers for my son. He is also 6 and symptons sound almost the same. We did 3 cleanings, 3 weekends in a row and he still had stool in his intestines. Had a sitz marker test which only showed that his colon is much larger/longer than it should be. And also every blood test there is. He is also on miralax and senokot everyday. We have good days and bad days. But I have to wear pullups on him and we change them about 5 times a day. I am in the process of changing GI docotors since I am getting no results. I would like to track your progress in hopes I can get some clues for answers.View Thread
