Hi Amarie,
It is your personal business what type of surgery you are having. I don't feel your boss has to know. I told my boss that I was having a surgical procedure and I would need 2 weeks off. I provided human resources with appropriate doctor excuse but it didn't say anything about diagnosis or why I was having surgery. It just listed how much time I needed and was signed by surgeon. Good luck on your surgery.
I had my sleeve on 4/3 and I can relate. I am barely consuming many calories and having difficult time getting as much fluid as I need, however, I don't notice change on scale. I am guess the more time we heal, we will see better results. Good luck!
