I had my surgery on May 17, and am doing well.
1. I was not told about Protein shakes, either way, by the Dr. A friend who had a gastric sleeve suggested them. They were convenient, but I wish I'd had fewer as I think they contributed to a really painful attack of constipation. I'd suggest low sodium V8, pudding, Jello, as soon as you are off clear liquids. I was a bit faint at times, when I was on liquids, but don't expect to hop up from any surgery and go play tennis!
2. broth, etc. sounds a good idea to me. Don't confine yourself to low calorie versions, all the time, as you are not getting a lot of energy from the clear liquids in any event.
3 They dissolve. I only had stitches at the port location. The other incisions were closed with super glue. Let it dissolve off your skin naturally.
4. I was instructed to take two chewable Vitamins a day (double dose) I found chewable adult vitamins that taste good.
5. First 2 weeks: liquids; not all "clear," V8, especially. Also pudding, jello. Next two weeks: "Pureed" food. Since I seemed to be tolerating it well, I pushed the limits a bit and had Imitation Krab--well chewed. I had about anything that was soft to begin with and that I could shew a lot. At four weeks I went on a cruise with my family that had been planned for about 6 months. I ate appetizers, Soups, and one or two salads, and carefully chewed. I did not try to eat even as much as I thought I could tolerate.
6. I haven't tried, but I should.
My doctor was not around that I consciously recall, but he has a good Physician's Assistant, and I asked her everything. I also suggest writing the questions down, and if the Dr. is a no-show, leave the list with the staff and ask them to get back to you.
