Boy, I dunno. It's major surgery and you can't go back--which sounds familiar
I'd give the same advice as for the hyst--find several opinions and do a lot of research and don't rush into it.
Maybe someone will come along and have personal experience, but I looked at it as an option--I am 130 pounds overweight--and I realized that it just wasn't for me. I can walk, I have no related health problems, and I'm sure I can at least make a dent in weight loss the old-fashioned way.
There's a good site on the procedures and risks and benefits here:
It's definitely not a magic wand and you're taking on some bad stuff--some of it for the rest of your life.
One risk is that the tiny pouch that's left stretches or the staples etc. breakdown and the stomach contents dump into the abdomen--this is very dangerous stuff.
You WILL have nutritional problems and have to take supplements and medications for the rest of your life--the scariest for us is the risk of osteoporosis because you'd have such trouble absorbing calcium.
There's a lot of reports of on-going nausea, weakness, sweating, faintness, and, occasionally, diarrhea after eating, as well as the inability to eat sweets without becoming weak and sweaty. So, you're still dieting, it's just enforced!
I found out that it can produce a liver condition that in 10% of the time can lead to liver failure.
And you'll need extensive plastic surgery to deal with the masses of loose skin.
Ten to 20 percent of patients require followup operations to correct complications.
1/3 of gastric bypass patients develop gallstones.
So it's not something to do without a lot of thought. But if you have a BMI over 40 and have obesity-related physical problem (such as body size that interferes with employment or walking) or a high-risk obesity-related health problems (such as severe sleep apnea or obesity-related heart disease) then it's literally a life saver and the risks are all worth it.
I suspect, that like hysterectomy, if you walk into it crystal clear on why you're doing it and realizing that you might have a lot to live with afterward, then you're likely to do better. If you go into it expecting to be the same you only thinner, then it could be a rough aftermath--the same as hysters can be.
Let us know how it goes. Whatever makes you healthier is a good thing.
