It really depends upon you and the people around you. When I had lapband surgery about 10 years ago and I was still working, I told everyone. I am the "no stigma" type of person as well. Since then I have retired and Covid hit so I don't see many people anymore, I only told immediate family. No neighbors, even though they see me walking and commented how good I look. I just say thank you. Most people just think I had hernia surgery, which I did. I didn't feel the need to go into details. Maybe because this was a revision surgery for me and I didn't want to share with everyone. After all, that is not as exciting as the first time around and I can just image people's judgment!
I think it is great that you have supportive colleagues, I did too. I even had a colleague go through lapband surgery the same time I did, we planned it together. So I really never have had any negative thoughts directed at me that I am aware of. But that was my experience. Unfortunately not everyone has that. I've seen many people here surrounded by others that are negative, even close family members. You need to do what is best for YOU. I wish you all the best!
