“I had mine taken out in 93 and always had a problem with going to the bathroom. I started taking fiber pills and it really helps and I no long eat fried and fatty foods.
I had asked a dr about this and he said that your gb filters the fat from your foods and when your gb is gone you are lubbing up your insides and that is why you need to run to the restroom and fast.
I have also had the weight problems to and I went to my dr about it and he put me on a 1000 cl diet and walk 30 min a day and that has really help me out.
I hope that this helps.
