I have a sister who the bypass 20 years ago-she gradually ate her way through the procedure and gained back all the weight she had lost. The gastric bypass is a surgery with all the complications that surgeries can entail. I had the lapband as it is a procedure that is less invasive (I went in at 6:00am and was home by 3pm same day.) My sister had vitamin deficiency problems as are a known problem-and lost alot of hair. There aren't vitamin absorbtion problems with the lapband as nothing is removed. My MD told me that my reflux would likely improve due to weight loss and it wasn't a contraindication according to my MD in Chicago.
