I've had bariatric bypass and it was the best thing I ever did. Have now lost 8 and a half stone. Do have minor problems with something called dumping syndrome and have reactive hypoglycaemia, which apparently is being see I more and more bariatric patients after surgery. However these are problems that although can be unpleasant I find I can manage whereas I couldn't manage to lose that amount of weight on my own. Each person is different and what is good for one will not be for others.
