I don't want to rain on anyone's parade here, but please, please research this VERY carefully before you make a decision. This is not a quick fix, and it is a major surgery. I have seen some research articles out of the US which suggest that:
1. while there is significant initial weight loss after three to five years most recipients have gained much of the weight back
2. there are high death and complication rates from all bariatric surgeries.
3. there are cases of people suffering from long term problems such as continual vomiting, and neurological problems caused by compromised nutrient absorption.
The human body is an amazing thing which is not fully understood and interfering with its natural capacity to absorb nutrients is dangerous - possibly more dangerous than carrying extra weight. Especially if you want to have a baby, it will need a mum with a full spectrum of nutrients.
I wish you the very best in whatever you decide but I really hope that you do some serious research before you make a decision.
