I feel all your pain. Been there. First significant thing that made a difference to my quality-of-life, was to start taking the psyllium fiber husk and the brand name is Konsyl. It has no citric acid or flavors added, it’s highly recommended by all surgeons in my area. I take a heaping Teaspoon about 10 minutes before each meal. This helps bind liquids and slow things down. If I’m going out I make sure not to ingest too many fats, oils, fried foods. This day the worst things for me are acidic foods like vinegar, eggs, coffee on an empty stomach, onion garlic spices, peppers. Unfortunately those Thai restaurants are a Big no-no for me. Any foods that burn like spices onion garlic peppers are not good. Try some herbs instead to make your food taste flavorful. Bring your own homemade dressing perhaps an avocado dressing or similar that has more herbs, no vinegars. Eggs, acidic foods, carbonation, coffee are all acids and more likely will burn just like spices. I do want to cuppa coffee I make sure I take the fiber before hand. Chocolates cause diarrhea so maybe have one or two squares after a meal. Start with the above. You’re some things to try so you don’t get too hungry then start making a list of what works, specifically for you.
In order to get my fruits and not have pain I use non-dairy milk like oat milk put in a blender with strawberries, or you can try some mixed fruits but I would stay away from those with too many seeds or tough skins unless you have a really nice blender It’s again if they have too many skins or seeds be sure you take the fiber Powder drink beforehand. It’s again, I tried many fiber options but the Konsyl brand was so much better than any Metamucil The extra price was well worth it. You want to be able to feel good and have some control. When I don’t feel full and I’m really hungry, I do pasta Dishes with steamed vegetables. I only eat soft to medium soft food. Soluble fiber instead of insoluble fiber’s Soft peaches, pears, Ripe bananas, Put soft fruits in your oatmeal to help bind them. Stay away from acidic oils, use avocado oil, olive oil but don’t overdo on them Red meat is a no-no, choose tilapia fillets, cod, steam them and they steamer with some steamed carrots, maybe some white potatoes And above all, make sure you take the fiber before the meal about 10 minutes before hand. When you’re on the road, or at a restaurant, you can always have some fiber tablets on hand so you aren’t dealing with the powders. Just keep some in your car or whatever it takes. As soon as you get to the restaurant wow the dinner is getting prepared, take some with your water. It’s not as good as the powder but it’s better than nothing When ordering try to order steamed fish and vegetables stay away from non-soluble fiber until things get better and test those out one by one when you can. This is an ongoing process, I’ve had it done at least 15 years ago but these made huge differences in my ability to feel like I could live a normal life.
You Read all the time about how high fiber diet’s are the way to go, whole grains, but realize your situation is different. Soft or medium fiber foods work better and if you have to use white bread instead of wheat in order to feel good then that’s what you do. You can get your fruits and vegetables in high quality blended super smoothies but I would still take the fiber before hand. By puréeing and using blenders, the kind it actually will liquefy your greens and fruits You can easily in just the nutrients you need without dealing with the fiber pain. Vita mix is a good one. Worth the $$$ to get the nutrition.
You need to buffer the liquids, acids, tiny particles of foods that sift down into the pouch by taking the Konsyl to help bind any of those acids or particles which Make it less painful to eliminate.
I hope this helps all of you. I can totally relate to your experiences. Each and everyone mine and hope to help.
