Confused about throwing up (sorry tmi)



Recommended Posts

I have read ((and heard from friends who had the surgery) that people with gastric bypass do not throw up, and that their stomach doesn't turn since it's a pouch now. I just ate something that didn't agree with my stomach. and I started foaming. The stoma was plugged, I believe due to a piece of egg due to improper chewing. I'll try better next time. After I spit out all the excess saliva, my stomach "turned" twice and it forced me to empty my pouch. I didn't get nauseated at all, it just kind of happened on it's own but my stomach definitely "turned" both times.

Can someone please explain to me if this is common for gastric bypass patients? I'm sincerely confused about it all. I hope I'm connected alright & nothing went amiss in my surgery lol. Thanks!

You will hear all sorts of stories because none of us is exactly the same…. My daughter had her bypass 10 years ago and she can throw up - she also gets things lodged. It’s common to ‘foam’ first before retching. I had my bypass 8 years ago and I don’t get things lodged; I also couldn’t actually throw up for nearly 8 years, but would foam (that would be the first indication something hadn’t agreed with me) and then retch, but not bring anything up. After my first radiotherapy session for cancer (they blasted my whole abdomen) I came home and tried to eat something and threw up and retched for 3 hours until my family got hold of a nurse on the phone and she recommended flat Pepsi or coke…. Must be flat. It worked. It’s been my go-to drink ever since (Pepsi Max Cherry, completely flattened, with ice 😆). Since then I threw up medication also with the treatment, but not since.

The important thing is to know yourself. As I understand it the stomach, when it’s very small, is often not muscular enough to actually throw up, but now I know it can be done! 🙄 - not that I wish cancer treatment on anyone…

I’m sure you’re connected alright - you also know now that you can get clogged and chewing things properly is really important. I used to foam at the mouth and feel I was going to throw up every time I tried peas in the first year - I think because I didn’t chew them properly and they were rattling round like little bullets… 😜 x

Thank you so much for your thorough response and flat Pepsi max cherry tip. 😁 And... I am so sorry you had to go through all that. I hope you are healthy now, and will live a long life.

Thank you for your lovely well wishes. I had ‘no evidence of disease’ in May after finishing treatment in February. My next scans are in November and I’m keeping positive. VERY important to flatten your Pepsi - your stomach cannot cope with carbonated liquid - and get the Max (no sugar) versions as otherwise the sugar will give you dumping syndrome as it will metabolise too quickly…. I have one bottle in the fridge (flattened) and another being flattened on the counter 😂. I keep squeezing and shaking, then letting the gas out. Once the gas lessens I drop a tiny lump of sugar in, and close the top not quite fully… If you do this too soon it will spill over - if you get it right it will de-fizz away nicely. Then when you think it’s flattened pour on ice, and that will finish it off… if you’re not sure stir it with a metal spoon. I keep a glass full in a shelf in the fridge so I’ve always got one ready 😜. I am a determined person.

I've thrown up several times since my surgery six years ago. I've also had that foamy business. I've heard that some people can't vomit after surgery, but I think most of us can.

Some of us do throw up, some of us foam and some of us do both...

I've done both. I've had gastric Bypass and had a lot of times when I did that... It was during the process of when I was learning what I could and couldn't handle.

I’m a sleever & I’ve found vomiting is different too. I wonder if it’s because we have fewer stomach muscles as well cause, on the handful of occasions I have vomited, it doesn’t feel like all my muscles are heaving. A win is I don’t have sore muscles after like I used to either. Plus I only need to throw up a small volume of food to empty my tummy.

I hate the foamies! I get them if my food is too dry, too coarse or fibrous. Begins with my restriction being more severe, followed by hacking & then spitting up small amounts of that foamy, gunky saliva. Can occur up to an hour after I’ve eaten.

My dad was told the same thing about the flattened cola with his chemo. It’s also useful for getting rid of the bad taste & reducing the coated tongue after chronic vomiting with chemo. Best of luck with your continued recovery, @Jacks133.

PS - Personally, I’ve never understood the whole ‘pouch’ description thing. Our tummies are exactly the same organ as they were before the surgery. They function in the same way as they did before (maybe a bit fussier). They are only smaller & for bypass have had a little shortcut rerouting to the intestines. They’re still stomachs.

Thank you all for responding!! That is one less thing for me to stress about. All this time I kept thinking something was wrong with my new revision because my stomach actually "turned" twice. One person I know in real life scared me and told me that she couldn't throw up no matter what since she had her gastric bypass and something must be connected wrong inside me 😅. I think she had her surgery back in the 90s. Not sure if the procedure changed.

I understand what you are saying. I always called my VSG my sleeve or stomach, not pouch. I can kind of understand the pouch idea with the gastric bypass because things get stuck in our "pouch", which is the size of an egg, and not our stomach. Thank you for your response. I only threw up once with my VSG in many years. Then again, I had a very conservative surgeon who made it 10 ounces instead of the 3 - 5 ounces. I wish I could say the same thing that I never foamed or threw up about my revision to RNY. 😆

After my bypass, for about three months, I would get sick and throw up if I ate something that didn't agree with me (like meats, hot or spicy foods, fried foods). I would get an awful feeling of pressure in my stomach and then get the foamies and throw up mostly saliva. One time the foamies and throwing up lasted an entire miserable night. But now I can eat anything I like with no problem. So I wouldn't worry about your stomach turning and the foaming. It happens to a lot of us!

What @Dinah said, just happened last W/E. Lots of saliva and very little food. I didn’t chew my eggs as thoroughly as I should have. It reminded me of baby spit up, only my entire abdomen felt horrible.

What does "turning" mean and feel like?

Sometimes if I get stuck, I just have to cough and the foam will come out. Turning is similar to throwing up like before surgery when one gets sick. Stomach contraction, noise and all.

Hi Lisa. They said that I didn't chew enough and it sounds like I temporarily blocked my stoma.

      I am new here today... and only two weeks out from my sleeve surgery on the 23rd. I am amazed I have kept my calories down to 467 today so far... that leaves me almost 750 left for dinner and maybe a snack. This is going to be tough for two weeks... but I have to believe I can do it!

      Hey everyone. I'm new here so I thought I should introduce myself. I am 53y/o and am scheduled for Gastric Bypass on June 25th, 2025. I'm located in San Antonio, Texas. I will be having my surgery in Tiajuana Mexico. I've wanted this for years, but I always had insurance where bariatric procedures were excluded. Finally I am able to afford to pay out of pocket.  I can't wait to get started, and I hope I'm prepared for the initial period of "hell". I know what I have signed up for, but I'm sure the good to come will out way the temporary period of discomfort and feelings of regret. I'd love to find people to talk to who have been through the same procedure or experience before. So I look forward to meeting you all. Hope you have a great week!

        I'm so happy for you! You are about to change your life. I was so glad to get the sleeve done in Dec. I didn't have feelings of regret overall. And I'm down almost 60 lbs. I do feel a little sad at restaurants. I can barely eat half a kid's meal. I get adults meals often because kid ones don't have the same offerings at times. Then I feel obligated to eat on that until it's gone and that can be days. So the restaurant thing isn't great for me. All the rest is fine by me! I love feeling full with very little. I do wish I could drink when eating. And will sip at the end. Just a strong habit to stop. But I'm working on it! You will do fine! Just keep focused on your desire to be different. Not better or worse. But different. I am happy both ways but my low back doesn't like me that heavy. So I listened (also my feet!). LOL! Update us on your journey! I'm not far from you. I'm in Houston. Good luck and I hope it all goes smoothly! Would love to see pics of the town you go to for this. I've never been there. Neat you will be traveling for this! Enjoy the journey. Take it one day at a time. Sometimes a few hours at a time. Follow all recommendations as best you can. 💗

        Thank you so much for your well wishes. I am hoping that everything goes easy for me as well. We don't eat out much as it is, so it wont be too bad in that department. Thankfully. Also, I hear you regarding your back and feet!! I'd like to add knees to the list. Killing me as we speak! I'm only 5' so the weight has to go. Too short to carry all this weight. Menopause really did a doosey on me. (😶lol) My daughter also lives in Houston. with her Husband and my 5 grand-littles. I grew up in Beaumont, so I know Houston well, I will be sure to keep in touch and update you on my journey. I may need some advice in the future, or just motivation. Thank You so much for reaching out, I was hoping to connect with someone in the community. I really appreciate it. 💜

      On day 4 of the 2 week liquid pre-op diet. Surgery scheduled for June 11th.
      Soooo I am coming to a realization
      of something and I'm not sure what to do about it. For years the only thing I've enjoyed is eating. We rarely do anything or go anywhere and if we do it always includes food. Family comes over? Big family dinner! Go camping? Food! Take a short ride or trip? Food! Holiday? Food! Go out of town for a Dr appointment? Food! When we go to a new town we don't look for any attractions, we look for restaurants we haven't been to. Heck, I look forward to getting off work because that means it's almost supper time. Now that I'm drinking these pre-op shakes for breakfast, lunch, and supper I have nothing to look forward to.  And once I have surgery on June 11th it'll be more of the same shakes. Even after pureed stage, soft food stage, and finally regular food stage, it's going to be a drastic change for the rest of my life. I'm giving up the one thing that really brings me joy. Eating. How do you cope with that? What do you do to fill that void? Wow. Now I'm sad.

        I hope your surgery on Wednesday goes well. You will be able to do all sorts of new things as you find your new normal after surgery. I don't know this from experience yet, but I am seeing a lot of positive things from people who have had it done. Best of luck!

        Life as a big person had limited my life to what I knew I could manage to do each day. That was eat. I hadn't anything else to look forward to. So my eating choices were the best I could dream up. I planned the cooking in managable lots in my head and filled my day with and around it.

        Now I have a whole new big, bigger, biggest, best days ever. I am out there with those skinny people doing stuff i could never have dreamt of. Food is now an after thought. It doesn't consume my day. I still enjoy the good home cooked food but I eat smaller portions. I leave food on my plate when I am full. I can no longer hear my mother's voice saying eat it all up, ther are starving children in Africa who would want that!

        I still cook for family feasts, I love cooking. I still do holidays but I have changed from the All inclusive drinking and eating everything everyday kind to Self catering accommodation. This gives me the choice of cooking or eating out as I choose. I rarely drink anymore as I usually travel alone now and I feel I need to keep aware of my surroundings.

        I don't know at what point my life expanded, was it when I lost 100 pounds? Was it when I left my walking stick at home ? Was it when I said yes to an outing instead of finding an excuse to stay home ? i look back at my last five years and wonder how loosing weight has made such a difference. Be ready to amaze yourself.

        BTW, the liquid diet sucks, one more day and you are over the worst. You can do it.
