Some things I learned from my surgeon yesterday about VSG that I had never heard before



Recommended Posts

So we all know about ghrelin... but according to my surgeon, once the brain detects ghrelin it starts to prepare for a fast. The body slows down the metabolism thinking we won't get to eat for a few days or something.

In addition, there's something called the omentum (I had NEVER heard of that before.) that serves as a fat depository, amongst a few other things. One of the problems with the omentum is that once your BMI starts getting over 30, it starts to act as a blocker between the nutrition you're eating, and your cells. And the more weight you put on, the more nutrition it blocks.

So what happens when you're not getting enough nutrition? Your body signals that you need to eat more by producing more ghrelin. Which in turn lowers your metabolism.

So, even if you just ate an hour ago, a fatty omentum will block your cells from getting nutrition, you'll make ghrelin, shut down your metabolism, and be hungry again..

Sound familiar? I know it does to me... sometimes I'll eat a whole large pizza, and be hungry again an hour later. My surgeon said it's one of the reasons he truly believes obesity is a disease. Because you have to not eat even when your body is telling you it's hungry.

Then all that sugar in your blood that the omentum is blocking from getting to your cells, just stays in your blood, and that is the cause of diabetes. (at least one type of it)

So part of what makes the sleeve so awesome, is it cuts out the ghrelin producing part of your stomach, which eliminates the omentum's ability to make you hungry when you shouldn't eat... BUT it also means your brain always thinks your stomach is full.... which means your brain is constantly running your metabolism at full speed.

I'm not an expert, just repeating what my surgeon said. But I found this REALLY interesting, and I thought maybe someone else on here would too.

Very interesting. I remember learning about the omentum in anatomy and physiology but I've never heard that theory!

Thanks for sharing this info. This definitely solidifies my decision to get the sleeve. It makes the surgery seem even more necessary to me now!

I have heard that there is just less ghrenelin because there is less stomach :( either way we are eating less and if have learned to eat healthy we will all do great :)

Wow this is truly interesting. It makes so much sense to me. This has also made me more sure that getting the sleeve is perfect for me. I may even print this page and let others see it so they can understand why I want the sleeve so bad and what could happen if I continue to overeat without help. Thank you so much for this.

This actually makes a lot of sense to me; thanks for sharing! I remember pre-surgery I would eat nearly constantly, and was fairly obsessed with food (so when I wasn't eating, I was thinking of what I would eat next). food really was an obsession for me, really almost like drugs must be for a drug addict. I think it was the carbs, too -- I was not much of a Protein eater prior to surgery (I really think I was addicted to carbs!). While I still do experience physical hunger, it is nothing remotely like it was before surgery, and I don't find myself obsessing about food like I used to before surgery.

Before surgery, my husband would let me plan out all the meals for the week because I was always thinking about food. Now he gets really exasperated with me because he will ask what we are having for dinner, and I will tell him truthfully that I really don't care what we eat, and that is 180 degrees different than how I used to be, and he is not used to that response!

I was reading an article in a bariatric journal that indicates within a few years after surgery, the sleeve will begin producing ghrelin, which is why you will always have to be careful about maintenance. Hopefully it won't produce ghrelin in the same quantity as before surgery!

      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. 💜

        Good Luck this procedure is well worth it I am down to 249.6 lb please continue with the process..

      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.
