I had the sleeve done 4 years ago. Lost 115 pounds. Gained about 20 pounds over the last year. I ended up with severe GERD, hiatal hernia and gallstones that cause severe pain. 9/6 I had the surgeries to fix all that which includes the bypass. It's been an interesting month. The healing process is different. Food going down too fast will definitely be coming back up (vomiting). Anything not chewed will be coming back up. Premier protein is smooth enough to stay down. Soups like French onion, chicken noodle (minute the noodles) veggie soup. Salmon. 2 good Yogurt and high protein high fiber oatmeal. Stays down for me. It's a big adjustment. I know that this is just a phase that we go through. I can eat boiled eggs now too. Eat slowly-chew slowly-swallow slowly. Drink 60 ounces of water. Follow the doctors orders. You'll loose weight
I've seen people successfully keep the weight off with both. They stick to the high protein/low carb and don't eat anything they did before ( that made them obese....like breads, maccoroni, rice, flour, sugar, fried foods).
How are you all managing constipation? That's been interesting.
Take care and give yourselves room to adjust. Things will get better. We make the best of the tool ( bypass) and it will work for us. Everything will workout for the greater good. We deserve healthy and happy lives and we embrace them daily.
