One thing no one has mentioned is about your question about losing weight without the surgery: I can lose weight really easily, but I can't keep it off. WLS resets your "metabolic set point" so it's easier to keep the weight off, though many people regain some weight. I've previously lost 50 and 100 lbs, but both times gained almost all of it back within a few years. I'm having surgery to give myself a better chance to keep weight off.

I am ten weeks out and have returned to eating almost anything I would have eaten while counting calories pre surgery and I have been lucky enough to not vomit at all so far. I had iron stomach before surgery and I think that is still true. I can also eat more than I should at this point though so it’s not all a good thing. I have to measure my food to make sure I don’t eat too Much because it doesn’t hurt my stomach.

I had bypass on April 14. There is indeed a steep learning curve as to what foods your new stomach can handle, but that is to be expected. However, my surgeon said some people never experience dumping at all. Personally, I have been very careful about what I’m eating and so far, so good!

This was one of my big fears, too, that deterred me from getting WLS sooner. I had read a lot of people's personal WLS experiences, and many of them seemed to talk about their pouch ruling their lives, and stuff about how they never know how their pouch will like something they ate, etc. I really hate vomiting and I was afraid that if I had WLS, it would happen all the time.
I am 10 months out and I haven't vomited a single time since surgery. There were a few close calls (early on, it's not uncommon for a bite of a dense/dry food like meat to get sort of stuck on the way down, which is very uncomfortable and can result in nausea, but in my case every time this happened, it worked its way down eventually). I have been extremely careful about what I eat, so I'm not even sure if I get dumping syndrome. My surgeon said I should make sure not to exceed 15 grams of sugar or 15 grams of fat in one meal to avoid dumping. I've stuck with that and haven't had any issues. I actually see it as a benefit of the surgery that fear of dumping keeps me in line. There have been some occasions where I ate a few bites more than I should have, but I didn't vomit -- just felt kind of stuffed for a while.
Unfortunately, there's no way of knowing how your individual body will respond to the surgery, but there's a good chance that if you stick to your plan, you won't have to worry about vomiting.

I just wanted to chime in because I am an EXPERIENCED DUMPER! This is not a title I hold proudly, by the way. I still dump sometimes for no reason at all. It has been the worst thing about this surgery, by far. They do say that gastric bypass has the most chance for dumping, but it most certainly can happen for sleeve patients, too. I am post bypass, but I still have to fight dumping nearly every day. Caffeine is a big trigger, sweets, fried anything and of course meat products. I wasn't told until after I had the surgery that a lot of gastric bypass patients cannot consume meat. This decision should not be taken lightly. I wish I could be this super supporter of WLS, but it's certainly not for everyone.
Talk to your doctor, please. Ask a TON of questions. Bring a notepad of everything you wanna know. Ask about things that happen to the small percent of people, because you could be that person. Like me. I promise the result will be worth it, but sometimes people don't want to pay the price of pain. ALSO - I don't vomit like I normally do. Because my stomach is so small, I usually regurgitate and food just falls out. OR if I have to "vomit" really hard, I have to cough to make my stomach push up enough to empty it. I usually blow blood vessels in my eyes because of how hard I need to cough.

GOOD LUCK!

about 30% of people with gastric bypass dump. You'll also find dumpers among sleeve patients, but it's much less common with sleeve. Which means 70% of bypassers (and even more sleevers) don't dump.
Dumping is caused by eating too much sugar (or for some people, too much fat) in one sitting, so to control it you just don't eat a ton of sugar (or fat) in one sitting, which we shouldn't be doing anyway.
in addition, vomiting after surgery is much easier than it was before. For one thing, we have tiny stomachs so there's not much in there to vomit. For another, you don't have much acid in your stomach, either, so you don't get that horrible taste in your mouth. I don't dread vomiting as much as I did pre-surgery.
I don't dump (never have), but I've thrown up. I did most often during the first two or three months after surgery as I was learning what my new stomach tolerated and how much it could handle. Now, I know. And now, I rarely throw up - probably not much more than I did pre-surgery, which was not very often.
P.S. I just read Nova Luna's response. Yes - the most common side effect with sleeve is GERD. About 30% of sleevers develop GERD - and/or it gets worse after sleeve (if you had it before). So there's that. Bypass often improves if not outright cures GERD. So basically, the stats on potential dumping (bypass) vs potentially having your GERD get worse (sleeve) are about the same.

Dumping Syndrome is generally linked to Gastric Bypass. It's from your food going from your stomach to your small intestines too fast. There is also only something like a 25% chance of you even having it. Gastric Sleeve has far less chances of that happening because your intestines aren't messed with but if you eat too fast then yeah, you'll feel like vomiting. Doesn't mean you will, but you may gag a bit. Also, drinking will cause your stomach to empty faster and could 1. make you hungry faster and 2. cause a dumping episode because you sent the food too fast through your system with the drink. If you DO decide to go the surgery route, you have to decide on whether you want the 25% of getting dumping syndrome with Gastric Bypass or the 30% your GERD will get worse with the Sleeve

OK, I haven't had a gastric bypass. I had a Loop DS, but I can only throw up if there's something in my stomach. Actually, last week, I had an episode of nausea, and would have vomited if I could, but I couldn't. I have an umbilical hernia that caused that.
My cousin, however, had a gastric bypass and she can't vomit at all.
I can say vomiting is quite different after surgery too.. It's not the big dramatic thing like before.

Just chiming in to say that it's pretty common to have a hiatal hernia fixed at the same time as bariatric surgery. I had both and a lot of posters on here have as well. I definitely wouldn't let that be the deal-breaker, your surgeon has likely done this double-surgery many times.

I had to revise to bypass and I cannot vomit and I am also a dumper. One bite too many is just as bad for me as a dumping episode.

I’m going to reiterate what was said by catwoman. I also hated vomiting. It is so much easier now! No heaving stomachache, nearly no acid. I’ve had it happen a few times when I’ve had one bite too many. It comes up easy and you feel way better once you do. It’s a good lessen to learn, to slow down and not take just one more bite when your body tells you it is full.
