How does a sleeve gastrectomy work?



Recommended Posts

Sleeve gastrectomy surgery reduces the size of the stomach by stapling along its length to form a long tube that looks similar to a banana. The majority of the stomach is then removed and discarded. The new banana shaped stomach is long and thin hence is often referred to as a ‘sleeve’.



Sleeve gastrectomy surgery reduces the size of the stomach by stapling along its length to form a long tube that looks similar to a banana. The majority of the stomach is then removed and discarded. The new banana shaped stomach is long and thin hence is often referred to as a ‘sleeve’.

About 80-90% of the stomach is removed making it much smaller, hence it holds much less food than it did previously. This smaller stomach helps you feel satisfied after eating a small amount of food. In addition, the part of the stomach that is removed is the part that secretes much of the hormone called ghrelin, which is involved in stimulating appetite. It is thought that producing less ghrelin further helps to reduce hunger after surgery. Although ghrelin levels start to rise again after surgery, they don’t seem to return to their previous levels and so hunger is more easily satisfied.

Unlike the adjustable gastric band the sleeve gastrectomy is not reversible. The stomach may stretch, or adapt to fit a little more food, but it cannot grow back. A sleeve gastrectomy therefore is a commitment for life.

As you will be eating less after sleeve gastrectomy, making the most of your food choices is important to help you obtain all the nutrients required for good health.

Following a sleeve gastrectomy most people will lose most of their excess weight in the first year. After this time weight loss often stabilises, so make the most of this period by making good food choices and regular physical activity a habit for life. After the first year, your ongoing success will depend on your efforts to change your lifestyle and maintain these habits in the long term.

Whilst the size of the stomach changes after surgery, the type of foods that can be eaten does not. Choosing high-energy (calorie or kilojoule) foods regularly will hinder your progress. As with other types of weight loss surgery, snacking or grazing, lack of physical activity and poor food choices can lead to weight regain. Positive, lifelong changes to eating and physical activity will ensure your long-term success.

Poor food choices can also cause dumping syndrome. Dumping syndrome had been thought to occur only following gastric bypass surgery, however it has been seen following sleeve gastrectomy surgery. Avoiding fatty or sugary foods will help prevent dumping syndrome. We will discuss dumping syndrome in a coming edition of the newsletter, but for now you can see a simple explanation here. Avoiding fatty or sugary foods will help prevent dumping syndrome.

A 2011 study found that those who had regular follow up after sleeve gastrectomy achieved better weight loss, health improvement, quality of life and food tolerance, than those who did not.

Great comments Sally,

I think the other item I would add is that drinking also makes a difference. I don't drink anything but Water, Powerade Zero, or other zero calorie drinks. I can manage an ounce or so of milk in coffee but its got to be a good amount of coffee and drank over a 10-15 min period or so.

      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!

      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.
