It will be gurgly for about
a week. Drink lots and avoid gassy foods. Foods that are high in fiber, but low in gas are best. Oatmeal, most vegetable except for peppers, onions, Broccoli, ...in other words, green beans, carrots, and LOTS of sweet potato and squash. that should settle things down really quickly.
Stay on your stool softener for as long as the cath is in. I would also ween yourself off it gradually.
