I have just found out I can have my goitre removed with surgery. I have been advised I will have a small amount of thyroid left but will be on replacement tablets long term. I have spent my whole life struggling with my weight and have finally in the last year got to a 'normal' weight range through dieting. I am terrified that if I have the op and start taking the replacement tablets I will gain weight. I think if this was the case I would not have the op but the goitre has increased in size in the last couple of years. I am in my early fifties. Any advice from anyone who has had this op would be greatly appreciated.
