Why sleeve and not bypass?



Recommended Posts

For me the choice was easy. Here are my reasons for not choosing bypass:

  • I had a lower starting BMI with less than 100 pounds to lose, so felt I didn't need such a "drastic" surgery.
  • Hated the idea of my detached stomach and intestines still just sitting inside me where they could still develop ulcers, cancer, or God knows what else while no longer being accessible with a simple endoscopy.
  • Didn't like the idea of losing the use of my pyloric valve.
  • More disconnections and reconnections meant higher likelihood of leaks.
  • Potential for dumping syndrome.
  • Potential for malabsorption and vitamin/mineral deficiencies.

Bonus benefits of sleeve over RNY:

  • The stretchy part of your stomach (the fundus) is removed with sleeve, but only partially removed with RNY.
  • The part of your stomach that produces ghrelin (the hunger hormone) is removed with sleeve.

I want to emphasize that these are MY reasons. RNY is a hugely successful and proven solution and is a fantastic option for a lot of people. You should figure out what is most important to you and what you can live with long term, discuss your goals and concerns with your surgeon, and figure out what the best option for YOU is.

I asked the same question to my surgeon and he did not make the recommendation for me, (thought he does for some based on their particular medical conditions). Instead, he lead me through the pros and cons of each procedure. For me, I was not full blown diabetic, (which can lead to a bypass decision) and I had 90-100 pounds to lose. Definitely no more. We finally decided that I didn't need the extra malabsorption (and the potentially more intense side effects) that comes with the bypass to be successful and went with the sleeve. I had some minor reflux, (which can also lead to a bypass over sleeve decision) but my doc attributed it to a hiatial hernia that would be repaired during either WLS procedure. I reached goal with no major issues 9 months after being sleeved and have settled into maintenance so I guess it was a good decision!

With the sleeve you still have to take Vitamins everyday correct? So what's the difference between taking them with the sleeve and with bypass?

With sleeve you are sure to absorb the Vitamins you take. With bypass, you could potentially still not absorb the vitamins, even with supplements and have to resort to injections or other more extreme solutions. It's not about taking vitamins or not, it's about being confident you are getting the full benefit from them. Also I know a bypass patient who have to take more vitamins than I do, because she developed deficiencies in the fat soluble vitamins (E & K). So, while I do have to take vitamins everyday, I don't have to take as many as a bypass patient might potentially have to.

I chose the sleeve for all the reasons listed including:

  • lower recovery time (2 weeks recommended out of work for sleeve and 3 for bypass). I am taking 7 days off work in addition to the two weekends. I am not telling anyone and just using vacation time.
  • I am at a 40 BMI, in my young 30s and no health related issues-- so while the bypass was sold as the gold standard, my doctor said I was not a good candidate because the bypass is a bit more extreme. He said if I had Diabetes he would give me the choice... but for me I didn't really have an option.

Just something to keep in mind:

Many people assume that a higher starting BMI automatically means that bypass is the best choice. That is not necessarily so.

I have two chronic conditions for which medication is essential to my well being, so could not have a procedure where the result would cause malabsorption. It was the sleeve or nothing for me.

My choice was simple...I didn't want the non used part of my stomach still in my body so I chose the sleeve.

My doctor reccomened it obviously for more scientific and medical reasons lol

I was worried about long term malabsorption and Vitamin deficiencies with bypass, so I elected for the sleeve. My surgeon said I was a good candidate for either (my initial BMI was 41)

Samantha did your BMI drop below 40 during your pre-op process? If so, how did your insurance company handle that?

I was afraid to lose and to be honest, my surgeon advised me not to lose to much during my 6 month supervised diet. Subsequently, I only "lost" 6 lbs in 6 months which brought my BMI down to 40 (and for that last weigh in I kept my phone, keys, heavy necklace etc. all on!) I think it depends on your insurance. In the end I had mild sleep apnea on the required sleep study, which meant I met the "comorbid condition" requirement so my BMI could be 35+. I have Meritain insurance.

Also to clarify, you still need to take Vitamins following gastric sleeve, and there is still potential for deficiencies with both sleeve and bypass. For me personally, I perceived the sleeve as having a lower risk for malabsorption because it did not involve bypassing a portion of my small intestine. Bottom line: there's benefits and risks to both surgeries.

My only issue was being hungry constantly, I was hungry and I over ate so I got fat. I have no comorbidities so the bypass just didn't seem right for me. I'm very happy with my decision. At 2 and a half weeks out I DO get hungry, but I eat my small portion and I'm completely satisfied. I have no desire to overeat (I'm pretty sure my sleeve would protest even if I tried!).

Yes I'm wondering that too, I'm at 42 now and scared to "lose" because I have heard insurance has denied people due to dropping BMI.

I asked exactly this of my insurance company (BCBS of Ohio). I was given a link to the medical policy. It specified that my starting BMI had to be at least 40, or at least 35 with comorbidities. I was concerned about doing the six medically supervised dietitian visit would push me to being out of the BMI.

That's when they asked me to re-read: the STARTING BMI, not the BMI at the end of the 6 visits.

I think I called the insurance company a dozen times to learn how all this worked. I'll bet they are glad I'm done now! haha!

In my case, my BMI at initial surgeon consultation was 40.2.

At the time we submitted to my insurance company it was 38.

Converting from lapband to bypass...my research...my lapband misery and damage to my esophagus and erosion ...Gerd...made it easy for me to know that cutting 85% of my stomach was not for me...I was initially going for the sleeve but for me bypass is a better option.....by the way my friend had the sleeve performed on her and her daughter 2 weeks apart and she is doing fantastic...everybody needs to do what they feel is right...and go with it.

Mine only had to show a loss. I lost 2 pounds. My BMI did not change. You need to "manage" this for your own benefit. The hoops they make you go through are sometimes ridiculous, and you need to play the game..."smartly". (is that a word?)

      Four days post surgery. I am sipping as fast as I can and getting NO WHERE near the goal of 60 - 80 grams of protein or the 64 oz of liquids. I just feel FULL. I don't know if it can still be the gas build up (I would think by now that would be gone) but it is a struggle to drink. And so far I have not had the nausea or spasms and don't want to wander into that territory by pushing too hard with liquids. I about passed out today as it was my most "strenuous" day. Went from second story to basement for shower and I was sure I was going to pass out. Looking back on my last few days I have had a total of less than 1000 calories. Am I just not getting enough nourishment in me? Once again a friday where I can't get ahold of the doc until Monday rolls back around so I am hoping maybe someone here has some experience on how to keep energy going. I do have fibromyalgia too and that may be where some added fatigue comes into play. How did you all fair with the goals the week after 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. 💜

      2. Selina333

        I'm in Houston so kind of near you and had the sleeve in Dec. Down 61 lbs. Feeling better. Was definitely worth it. I hope the everything is going well for you. Update us when you can!

        I am back home after my bypass surgery in Tiajuana. I'm post op day 4. Everything went great! I guess I'm one of the lucky ones who have not encountered much pain at all, no nausea thus far and I'm having no problem keeping down broths and water. Thank you for your well wishes. I cant wait to keep up this journey and have a chance at better health and simply better quality of life. I know there will be bumps in the road ahead, and everything won't be peaches and cream, but at least I have a great start so far. 😍

      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. 💗

      2. Doughgurl

        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. 💜
