Hello,Haven't made a post here in a while but I think I am starting to find out what is wrong with me.I was diagnosed with IBS like 6 years ago and I tried a variety of anti constipation meds, even steriods, and nothing worked.About 2 months ago I had a colonoscopy, everything was normal, very frustrating when you are having incomplete evacuation every time you go.I changed my Doctor(And Thank God for that because if I still would have been at the old one I would have still been drinking water and eating vegetables to cure pelvic floor dysfunction).I got a sitz marker test done. It was a little slow but relatively normal.But the real catch was in the Defography/Defecation test.Diagnosis- Patient was only able to evacuate 10% of the barium(White paste stool). After taking nearly double the normal amount of barium, the diagnosis is an abnormal condition. The patient appears to have a normal digestive tract and colon, but has some kind of abnormality.I talked with my doctor later and he didn't exactly know what was wrong with me. I passed the test(When the doctor sticks their finger up your butt) normally, but the push or force against his finger was very, very weak. So I must have some kind of muscle impairment, that doesn't allow me to completely push out the stool.if you are wondering what a simple definition of Pelvic Floor Dysfunction is- When you take a ####, only a little bit comes out and the rest usually has to be manually removed or else you just have stool sitting up below where it should be. Which is a more than just a little uncomfortable, trust me.
