I am two weeks post op and just transitioned to "soft proteins." I work in a small office and we always go out to get lunch and eat together as a group at the office. I told everyone that I was out for hiatal hernia repair and have explained to them that I have some diet restrictions as a result. All last week at work I ate my purees/liquids at my desk. This week I decided to join back up with the group and I am getting so many inquiries about my small portion sizes and diet plan. Its getting difficult to keep up the charade. I want to eat with everyone else like normal. I don't want to be rude, but I do want all the questions to stop. Any advice?

I am not criticizing your choices at all. I don't think you should have to disclose your choices to your boss or your co-workers and if you worked some place with better protections, or if we had better protections in general in the US you wouldn't be in this position.
You told a cover story to get time off and now you have to stick to it. Adding more layers to it, makes it more complicated and more likely that you will be detected.
I completely understand why you said hernia not VSG but your boss and co-workers might not be as understanding, at least you don't think they would be or you would have told them in the beginning. No one should be in a situation where they have to be dishonest about taking a proactive stance on their health.
Good luck OP.

Thanks for clarifying. I appreciate the support.
