do we change after surgery

I don't think gaining or losing weight can change your morals, values and beliefs.  I think personality can change with lost of weight and for some people it is a good change and for others not so good. 

I am happy with my changes and even though some of my friends are not that is OK with me.  In the long run I must be the one that is happy and my husband be happy with you I am and he is. My number one fan at my races.

Behaviours certainly change with losing weight - better choices, etc. And yes, you are the one who must be happy with who you are. You are very lucky to have such an awesome supporter in your husband. And he is very lucky to have you!
