I have kind of had a similar situation, except my husband is the one that got banded. My boss and co-worker say rude things about overweight people alot, so I never mentioned that my husband was overweight (no need to!). When the day of the surgery came I told them he was having an outpatient surgery done. My co-worker finally came out and asked what was going on but I just told her I didn't want to talk about it. That ended the conversation. If anyone should be embarrassed it is them, not me, but I still just feel that it's none of their business. So I understand what you're feeling! It's kind of tough.
