5 yrs since my surgery and I never lost any of my hair but I think maybe it depends on the type of surgery...I had Lapband where I have girlfriends who have had Gastric bypass and have lost their hair...I would guess it's because of the nutrients and vitamins ur body is no longer receiving that causes this issue...Make sure u take all ur supplements and keep ur hair oiled and make sure u keep all the tension (no tight ponytails or braids).

I agree it does hurt.  Don't let them gain power over you.  What is just as sad is that a supervisor at my job is telling people that I do nothing but show off how much weight I lost.  Guess what, you and I know that it wasn't an easy journey.  So we are getting a lease on life.

You had a slight setback, but you are taking control back.  And we are learning who are real friends are.   So get rid of those friends and find some new ones who accept you as you are.  I am doing the same. 

Best of luck on your journey.
