Hi Donna .
To be honest the list is quiet extensive and comes in various genres tailored for different patients ..
I would suggest you call a weight loss hospital or a weight loss broker , like The Hospital Group or Obesity Surgery centre .. They will ask you about your weight , eating habits etc and then advice you the best surgery for you ..
It does clime down to cost though if your going private of course and how much you want to spend ..
A gastric band is approx £6,000 which isn't perminant and can be removed , or permanent surgery like a mini bypass that can be the best part £11,000 , if done in the UK ..
please take plenty of advice and time over choosing the right one for you ..
