Please go with the sleeve! I am 3 months post op from revising from the band to sleeve. It was the best decision I have ever made and have already lost 50% of my excess weight.
First of all with the band you do not have immediate restriction. You have to go in every month for fills which was a pain for me since my dr was an hour away. So for the first year or so the weightloss was all me. There is a very fine line in between the "sweet" spot and too much fill. Once you are over filled life then becomes misery! I could no longer eat any kind of meat or fibrous veggie without throwing up. I had gotten to the point that I was throwing up at every meal every day until I started turning to slider foods. Which is junk! All junk when down with ease! Which resorted to me gaining back 20 of the 60 pounds I had lost over the course of 3 years. Yup it took me that long to lose 60 pounds!
Now lets talk about how unsafe the band is and all the severe issues that the band can and will likely cause.
Prolapse, acid reflux, slippage, erosion into your tummy, port flips, erosion and protruding. Another thing is when you have too much of a fill for too long. They have to empty your band and you start all over filling it up again. I have also recently heard that the band is not meant to last forever and needs to be replaced every 10 years!!!
Yes the band is less invasive of a procedure but look at all the health issues you could be facing with it. Is it worth it? Not to me.
Yes the band is reversible but so will your weightloss. I only know 1 person out of the 15 people that I know who have had the band ever get to their goal weight. Had I been aware of the sleeve prior to me getting the band there is no way I would have ever chose the band.
Good luck with whatever decision you make!
