Question : What are the downsides to gastric bypass surgery?
specifically what are the nutritional ramifications because I have read that B-vitamins and protein cannot be absorbed because of the portion of small intestine that is bypassed. Also, what happens if there is a pregancy? What happens to a developing fetus if the B-vitamins and protein is not accessible? What are other downsides to gastric bypass surgery? I want to make the best informed decision and I am afraid that I am only hearing of the “up” sides of surgery or at best “sugar coated” negative sides to the surgery. I would like the most information anyone is able to give me! Thank you!

Best answer:

I’ve heard you can eat only small amounts of food OR liquid at a time, not both.
The feeling that ‘hey, I didn’t do it myself’.
