Am I being too sensitive about this or would this bother anyone else?

Only my immediate coworkers know about my surgery. I wasn't planning on making a big announcement. But this afternoon when a group if us where going to the cafeteria to eat lunch somebody asked me what I was doing to loose weight. My answer has always been "smaller portions and hard work". It's not a lie... it's just as much of the truth I planned to tell most people. Not two seconds after I gave that answer to this person I barely know one of my coworkers who knows about my surgery blurted "she had surgery" as the answer. I'm so mad! I feel like her saying this makes it sounds like such a simple process and surgery was 'the easy way out'. Am I just too sensitive about it? Should I say something?

Wow. I'm amazed that some people believe that because something is true, it must be public. I disagree very strongly with that notion. I have the right keep information about my body private. Period.

It sounds like your co-worker does not believe in a right to privacy and she should not be privy to medical information. I understand you not wanting to rock the boat and I respect your decision, but I might have reported her.

I would have been sooo mad! You're def not being a baby
