What changes can you expect after gynecomastia surgery?

I am a woman in my 20s considering gynecomastia surgery. I am curious about how the body changes after the operation. In particular, I would like to know about the reactions of those around me and my own satisfaction levels, as well as what difficulties are typically encountered during the recovery process. I would also like to check what kind of care is required during the rehabilitation period. I would appreciate opinions from those with experience or recommendations for trustworthy hospitals!
