Non-Dumping Syndrome Dizziness and Nausea?



Recommended Posts

I’ve tried researching this myself but so much of the advice assumes you’re “cheating” and dealing with dumping syndrome.

Has anyone else experienced EXTREME dizziness, flushing or cold sweats, and nausea right after eating a few bites or small meal?

I’m 22 days post-op and for the last week or so I’ll have these absolutely horrible bouts right after I start or finish eating. It’s not after every meal and it seems totally unrelated to sugar/carbs/protein/fiber or any other obvious nutritional element. Half an hour ago I got two bites into one of those often recommended ricotta bakes and it hit me. At lunch today I had a tiny serving of mashed avocado and hummus and it happened within like 2 minutes of finishing. It happened after a coconut milk based yogurt for Breakfast on Monday.

This isn’t happening any other time - it’s right after some but not all foods but there isn’t an obvious pattern to what foods or times of day. That makes me think it’s also not dehydration because you’d think that would impact me other times, right? It shouldn’t just be when something hits my stomach?

I’d be concerned about a leak but I don’t have a fever or swelling or pain in the area either. I’m stumped!

Out of curiosity, have you taken your blood pressure when this happens?

Yes, nearly every time I developed the “foamies” from eating something that didn’t agree with me. Most of this was texture based or eating too quickly and earlier on after surgery (first 2 months was the worst). Aside from the excessive saliva produced. I’d get extremely dizzy, nausea, cold sweats, and almost black out before and after vomiting. I’d also have severe fatigue afterwards for 2hours or more.

I would talk with your team. I also know I wasn’t given the ok to eat any of that stuff until 7 weeks out, and only after getting my Protein in first. I got those symptoms after 2 bites of “protein ice cream.” It was classic dumping. It could have been the fat or the sugar, either way it’s not something I want to repeat. Talk with your team!

Hypoglycaemia was my first thought. I have random episodes (light headed, cold sweats, want to vomit but don’t, diarrhoea cramping but nothing, almost faint) but not during or immediately after eating. Water, cup of tea, a few blueberries or strawberries help me.

Contact your medical team.

It could be the fat - the ricotta bake, avocado, and hummus are all relatively high in fat and fat can cause dumping in some people.

But definitely talk to your surgery team and see what they say. I hope you find an answer!

Weeks 3-5 were my worst for my stomach to veto certain things, and you are correct that it can be healthy things. After 6 weeks, it was almost magical. Rarely any foamies and/or disagreements.

My team unfortunately knows very little about cases like mine as I also have Ehlers Danlos syndrome.


I’ve already run into several occasions where they gave me dietary suggestions that work for most people that didn’t work for me because of the various comorbid orthostatic conditions associated with my EDS. I’ve only found 4 or 5 people online who’ve ever had GB with EDS.

And the issue is even faster than dumping syndrome levels of fast. Like 1 bite of mashed avocado (which is on my post op diet) and it was happening - I think it’s just EDS stuff at this point. Any level of digestion pulls blood away from the rest of your body and that is, I think, what my body is reacting to. Sigh.

Nope, almost no fat in the ricotta bake. It was fat free ricotta and 1/3 of an egg in my entire meal and it happened within 30 seconds of the first bite. Happened within the first bite of avocado and was full blown in under 5 minutes.

I would definitely contact your team as that is not typical if it is not dumping. They should have some answers for you.

Definitely let your team know this is happening.

It seems like it will be trial and error for you to determine what foods do/don’t sit well with you. Avoid the ones that don’t for now.

Perhaps try to keep your foods simple for a while (one ingredient) to rule out sensitivities. You are still in the early days so it could just be temporary intolerance.

One other cause could be foods that are digested too quickly (everything you mentioned is very slippery smooth) may affect you this way.

Feel better soon!

      2 days until I fly out to San Diego to have my Bypass Surg. in Tiajuana Mexico. Not gonna lie, the nerves are starting to surface. I don't fear the surgery itself, or the fact that I'm traveling alone, but its the aftermath that I'm stressing about the most, after this 8 week wait. I'm excited to finally be here, but I am really dreading the post surgical chapter. I know its going to be tough, real tough and I think I'm just in my head to much now that the day i here. Wish me luck, Hopefully I'm one of the lucky ones, and everything goes smoothly. Cant wait to give an exciting update,. If there is anyone else have a June bypass or even a recent one, Id love to have someone to compare war stories with. Also, anyone near San Antonio Tx? See ya soon with the future me. 💜

      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.
