What type of diet were you given?  I was on a low residue diet for about a month.  Check with your surgeon’s office if you weren’t given direction as far as that goes.  For each of my surgeries, I was on this diet for a period of time.  

Many folks are given fiber supplements 1-2 months post takedown to help the stool bulk up. I was given immediately after takedown. 4tsp at night to help me sleep better. The pysllium husk powder has helped me big time. Even now I take 1.5 tsp in morning and sometimes 1tsp before dinner, its the best thing and I also started taking 1 imodium caps. (2mg) in the morning thats the only thing I have to take. I wouldnt say shy away from fiber altogether, just dont have fresh salad, fruits, high sugary foods, nuts, or excess dairy in the first month. Its a learning curve from here on. You can add foods and see how your body reacts to them. Some foods may feel better now and some not. But as time passes the pouch stretches and you'll tolerate foods better n better. Also I find banana extremely helpful to stablise my output although its high in fiber. Good luck 👍

I’ve been on soluble fiber (psyllium) twice daily since my surgery 17 years ago. You probably should go easy on insoluble fiber in the beginning, and over time explore your body’s tolerances for salads, fruits, etc.

After takedown I ate food with soluble fiber, no insoluble fiber foods. No raw vegetables, no fruit peel, no nuts or seeds, not even multigrain bread!  Just remember that insoluble food can hurt on the way out because it doesn't break down completely; soluble food becomes gel-like and soft in the gut. Cooked zucchini helped me, also cooked spinach. Sweet potato was introduced in time. Well cooked oatmeal with sliced banana on top. Pasta with pesto sauce or good olive oil, but not acidic tomato sauce.  Currently, I am eating 1/2 a ripe avocado per day, mashed on toast with salt and pepper. It helps me 100%, and it supplies a good fat. Try to avoid fried foods and sugary food or drinks because it can be messy. Watch out for sugary yogurts, go with high protein Greek yogurt with cinnamon or nutmeg if you like yogurt. I didn't use supplements; they didn't seem to work for me, but food did. I am three years now!
