I had RnY gastric bypass on October 18, 2022.
I was told that straws were allowed, as long as they didn't cause gas. So, I've been using straws since the day I came home.
If you get the bariatric vitamins, then you'll only need to supplement some calcium. You can buy them separately, but if you do that then you're going to be taking a handful of pills, multiple times a day. And it's really not anymore expensive to just buy the bariatric ones. I got the chewables.
The soups you can use are going to depend on your stage. If you're on clear liquids, then you won't be able to have cream soups. Once you're on full liquids, then you can have cream soups - you'll just need to strain them.
I was allowed to shower the day after getting home - so on my second day post op.
I packed an extra long phone charger (didn't need it), a heating pad (didn't need it), an abdominal binder (I didn't use it in the hospital, but I did use it for a couple of days after I got home), an old pair of slippers that I planned to just throw away (I did use them when walking the halls in the hospital) and a robe (I did use it when walking the halls in the hospital). Other than that, I just wore home the same clothes that I wore to the hospital. I knew that I was only going to be staying one night, so I didn't bring any toiletries.
I did not have a drain placed, thanks be to God. I've heard those are unpleasant to have removed.
