Literally asking for a friend. What are your thoughts on MGB for a lower BMI patient, like someone with max 40-50 lbs to lose?

I started with a BMI of 35 and had the sleeve 4 months ago.

Unless the patient has GERD, I'd tend to lean towards suggesting a sleeve for a fellow low BMI patient. Low BMI patients tend to have the the best results - on average they lose 80% of their excess weight, compared to 60% for the higher BMI patients, and many reach a normal weight. There's only ~5% difference in weight loss between the sleeve and bypass type surgeries, but bypass surgeries are more likely to lead to certain types of Vitamin deficiencies in the long term. A high BMI patient might want that little extra kick of a malabsorptive procedure, while a low BMI patient is likely to not need it, so why take the extra risk?

I am a low BMI and had my sleeve op. rjan is right, bypass causes Vitamin deficiencies & are bigger ops than sleeve. Low BMI's do not seem to need it that's why the surgeons prefer sleeve.

Low BMI/need for lower fat loss is the only reason I can see that there is to use a sleeve. I know some might disagree on this - but sleeve is really best if there is ONLY a little weight loss issue. All other commodities are best solved with a bypass solution, thus also decrease the risk of revision.

I think a lot of surgeons prefer the sleeve because it's easier and quicker to do. Also, Vitamin deficiencies are rare in bypass patients as long as they keep on top of their Vitamins.

Studies do show significant differences in nutritional deficiencies in sleeve vs. bypass.

The incidence of ND at 1 year postoperatively was generally less after SG than RYGB (34% versus 37% for zinc; 18% versus 28% for iron; 4% versus 8% for albumin; 32% versus 52% for Vitamin D; and 18% versus 58% for vitamin B12) except for folate deficiency which was higher after SG than RYGB (22% versus 12%).

they can be more of an issue with RNY than VSG, yes, because of the malabsorption factor. But as long as RNY'ers are diligent about taking their Vitamins, deficiencies are rare.

This is interesting, I was not made aware of this. Can you tell me the source of this information?

Well it depends on their BMI and the surgeon you're dealing with if they will even do a bypass surgery; but from experience I had the RNY bypass and had not one single issue and lost ALL my excess weight..

Your friend needs to research more before deciding if they want to put their body through surgery for only 50lbs?

This clinic reports their results for different BMI ranges on their website; results are shown all the way up to 5 years out.

interesting - looks like there's a difference if it's a size 40 bougie, but about the same if it's a size 36 bougie. I didn't have VSG so I'm not sure which size is most often used.

I had bypass surgery with a BMI of 32. I have 40-50 pounds to lose. I chose bypass because I have diabetes and the bypass helps that greatly.. I had surgery a month and a half ago and have lost just over 20 pounds. I wanted a permanent fix to get diabetes under control. Diabetes is getting better. I also had acid reflux and the sleeve can make that worse.

it's a really personal decision. I thought 50 lbs would be the amount I lose and I went with having the surgery. I am really glad I did.
