Hi Ana,
I recently had a laparoscopy and I also have lost my appetite for the things I was eating before. I also feel nauseous just thinking about some foods that never bothered me before. I am quite sure this is a residual effect of going through surgery or surgical procedure. As far as the incontenence and headaches, you sould contact your doctor immediately because you could have a bladder infection. I'll be praying that Jesus will heal you - He is able!
