some hearsay about WLS

I read this account, by "Robin" and thought it might be relevant here.

" I have 3 friends who have had that surgery....the first one had
horrifying hair loss....daily vomiting even almost a year later,
sickly something terrible, another has had the surgery and did not
lose hardly any weight because it didn't take...or they suggested
that she might have just stretched her stomach back out thru over
eating, the third, he lost weight but has had to have 2 subsequent
surgeries to find out why he stayed in pain a lot of the
time.....None of them died but I know at least 2 of them might have
had serious regrets about having done it. The really crazy thing is
that with the first one...she had the surgery and her doctor told her
she had to eat low carb basically for the rest of her life...... IMHO
she could have done that without going under the knife....She is very
sensitive about it so we don't talk about it but I know it has been
frustrating for her to find out post surgery that she was still going
to have to eat according to an eating plan that she tried and could
not do pre-surgery..... I will stick with the Atkins and spare myself
the knife......That surgery scares me! "
