Monday and today, I had some oily film on top of the toilet water after my bowel movement. I noticed it happened just Monday and today, which happened to be after I had some Collard Greens on Sunday and Tuesday evening. I have always had issues digesting vegetables well. The collard greens I ate were pretty oily, is it possible that this would cause the oily film, or would my body have digested that well enough?These 2 times are the first I have ever seen anything like that. No oily film Sunday or Tuesday, just the days after I ate it.
