Hello, Sorry to hear about your problems after surgery. I had a partial gastrectomy where I had 80% of my stomach removed. They also did a ru en y. My surgery was for bad acid reflux. I previously had a nissen fundoplication which failed horribly. I know since my surgery I have to avoid simple sugar. Protein shakes do cause problems for me. I have found the only ones I can drink are the Atkins shakes because they have no sugar. I can eat fruits fine. I would suggest getting another opinion or 2. When my nissen fundoplication failed I went to the same doctor and he didn't give me much hope. I went to 3 other doctors for opinions. I went online and researched surgeons that specialized in digestive issues, found 3, scheduled appointments and met with them, took all my test results, and met with them to see what they thought would help. Luckily I found a surgeon that had 30 years experience in digestive surgery. He in detail explained and showed me (in drawings) what he could do for me. I had similar symptoms you explained after my nissen fundoplication. Since the partial gastrectomy I had in March of 2019 I am so much better. 210 isnt that heavy. Why did you have the gastric sleeve surgery?
