Personality change after gastric bypas

I don't mean to rain on anybody's parade. My mother recently just went through this surgery and I believe she's changed for the worst. When I look at her, and not at her body but in her eyes she's not the same. And I get that the surgery is suppose to help with her confidence, and her overall mood in life. But I think as part of the surgery it went a little beyond that. Theres a certain extent where over confidence kicks in, and I believe she's obtained that. She's doing things she never would've done before. I get the whole I was used to how she used to be, and I'll adjust to the new her, but morally she's not the same. Confidence isn't suppose to change your morals. I can't blame it completely on the surgery, maybe its was just her all along and now its just more obvious, but its like people believe your life only starts when your skinny. Its not true, you don't need to date everyone in the world once you've lost 60 pounds mom. And everything came after the surgery, is this the surgery's fault or is it just my mother? Im just confused. 

A lot of people who are obese,  are obese because there  is an underlying psychological issue.  Some of us use being fat as a way to protect ourselves.  Take that away and we are stripped bare and have to find new ways to cope with our problems.  

You should talk to your mother and encourage her to seek therapy.  But then again,  maybe she's happy the way she is.  

Good luck. 

I was looking into other peoples' experiences, and yours is most like mine.  My sister and I became extremely close when we were each single mothers. For years, we did everything together--all weekends, holidays and vacations.  I was her hospital buddy when she had her surgery.  Within a year, or so, of having the surgery, she became extremely bitter and vindictive.  She's caused untold problems among the family and seems to delight in the attention she gets by dividing and conquering.  She's screamed at both of our elderly parents about what terrible parents they are (THEY ARE NOT!), and further, falsely accuses others of horrible things.  Her perspective is like no one else's.  Simply, I wonder if there are physiological changes that occur in the brain with such extended "starvation."  

I too have a similar issue. My best friend and i havent spoken in about a year. I was happy about the surgery, but all of a sudden an arrogance kicked in, not confidence, arrogance. Lecturing me on what to eat, answering for me at questions directed to me. I went through a hard time at work laying off people, and the conversations ended up revolving around them. They were the center of the universe and bragging about all they did. This was who they truly were underneath and i dont have time for that. I have known too many others that are not affected like this. It is really strange and upsetting. I see other comments ,"maybe jealous..." So on and so forth but this is not the case here, this is not the person i have known for 35 years, or maybe it is.

I understand that you are seeing something not connected with jealousy or lack of comfort.  My sister is just, plain bitter and mean.  Nothing makes her happy, and she'll be damned if anyone else can be happy, either.

As I said in an earlier post, I lost my sister the same way.  I don't believe I said anything insulting:  She's my SISTER, and I cheered for her every win!  Somehow, she became a bitter, mean person.  She is NEVER happy--thinner, still, but never, EVER happy.  I don't think this has to do with her weight or her struggle. (I've fought fat all my life, too!)  I feel that something in her chemistry has altered the way her mind works.  I simply do not know this person, and it's becoming so that I do not want to. Are there any studies about the physiological changes that occur during starvation?  That's been my quest.
