hi I'm 30 years old, had a full hysterectomy two years ago. I had a lot of problems with my bowel movements and periods. Well before the surgery my BM's were bright yellow diarriah with like stringy stuff in it. It went away for a year and a half after the surgery but has come back again. I had endometriosis before the surgery and the dr and I both agreed that's why I was having bm problems. My stomach cramps up all the time. I have to run to the bathroom or I am not going to make it. It's always when I wake up that this happens. And I get nauseas all the time too.
