I am not poopy! Once in the morning, just like before DS. I am rarely gassy but did recently learn I had become lactose intolerant (only to milk/cream, not cheese, ice cream, yogurt, etc). Once I eliminated that, I've been fine.
Make me so mad when surgeons who do not do a DS (proper or bastardized) say this stuff either to convince people to accept an inferior surgery that they perform or because they've been giving inadequate nutritional advice to DS patients.
Everyone's recovery is different. I had a virgin DS when I was old (62) and I was FINE. No pain to speak of after I left the hospital. When I left the hospital after 4 nights, I took no pain killers, not even a tylenol. (Do try to make them let you stay as long as possible. None of this one night and out the door crap.) Seriously, I was walking a mile in 10 days. I was however really REALLY tired for about a month. I'd take that mile walk and then fall asleep in the chair for 2 hours. My tiny trocar incisions disappeared -- no one looking at my abdomen would ever think I had a laparoscopic procedure. In fact, a nurse practitioner demanded I show her where they were as I think she thought I was lying about having surgery.
The research clearly shows that RNY is not successful long term. People with RNY have to diet like mad after a few years and, hey, how has dieting worked for you in the past?? Never worked for me!!! Will you be here asking about how to get a revision in 8-10 years? (And there are only a handful of surgeons qualified to do a RNY to DS revision.) I would never ever have had a RNY. IMO go for "one and done" By 13 months post-op I was 125# at 5'5" where I still am at 25 months post-op.
I tried to look into him (David Parker @ Geisinger Medical Center in Danville PA?) but only see "bariatric surgeon" not the specific types he personally performs. The bariatric department does do a DS but I cannot tell if it is the proper one or not.
Again are you sure he has sufficient experience to perform a PROPER TWO ANASTOMOSES DS with limb length based on the Hess Method or a cookie cutter max common channel length of 100cm? His pushing a RNY may be because he really doesn't do a proper DS. What you don't want is for him to do some sort of Franken-switch one anastomoses SADI/SIPS/Loop or a sort-of DS with a ridiculously long common channel which will not be successful for you.
Think twice, cut once.
Best of luck to you.
