I can't resist responding to this thread, even though the origins are old...
I had a vertical sleeve gastrectomy in March, 2013. Afterwards, I had serious, life-threatening complications and spent five weeks in the hospital.
It took me a long time to heal and begin to regain my health. I don't know how things might have been with recovery from the surgery if I hadn't gotten pneumonia and pulmonary edema.
But...despite the complications, my experience suggests that - unless you do all the 'right' things (doctor suggestions) after a bariatric surgery, people will have poor health and possibly die.
So, what are the 'right' things? Well, for me: I take lots of vitamin supplements, I eat 6-7 small meals of mostly protein a day, I exercise regularly, and I am very serious about getting enough sleep.
If I don't take my vitamins supps (for the record, I took a lot before surgery too) and get enough sleep every single day, I feel TERRIBLE.
Today, I feel better than I ever have in my life, but it does take some effort. I take better care of myself than I ever have.
Surviving on milk shakes and tomato soup (as someone mentioned) would NOT work for me. (There's a lot of sugar in those items, for one thing.)
Despite surviving and thriving (eventually) after the surgery, though, I would not recommend bariatric surgery to anyone.
Why? Because - surgery or not - I have a complicated relationship with food and an eating disorder. Surgery did not fix those problems.
I didn't expect that it would - I hoped it would be a tool in my weight-loss strategies. But it hasn't been as useful of a tool as I had hoped.
The eating disorder is a very powerful problem (compulsive overeating.)
But - for those who are smugly complaining about people butchering their bodies and regaining the weight, I have this to say: have you ever felt so desperate about losing weight that you would do anything? Even if it was dangerous?
Well, I felt that desperation. And that's why I had the surgery. I don't regret it. Now I know.
I basically eat very similar to how I did - low carb - before the surgery. The VSG, however, prevents me from binging because it only allows me to eat much smaller amounts.
That binging restriction is one of the effects I hoped to achieve from surgery - and it works well, as long as I do not eat sugar.
I still go to Overeater's Anonymous to deal with the eating disorder. It's one day at a time. Some days, sugar looks pretty good - and I eat it, to my detriment, surgery or no surgery.
All I can do is keep trying.
I have had people tell me a bazillion stories about their friend/relative/cousin's pet dog's hamster's niece having this or that bariatric surgery and how poorly these individuals did afterwards (and/or died).
And when I asked them for details, everyone of them admitted the person in questions was NOT following post-surgery guidelines.
YMMV. Peace.
