I'm glad I'm retired.
Don't have to deal with people at work in any form.
Sorry this person may have issues also.
I had plenty of issues before any surgery was done.
But I was never pestered by my fellow employees.
They knew my issues. I wa never embarrassed by them. So they knew before and after my surgeries.
Keep using the bathroom you are using. Tough Tata if he needs it. He can wait or use the men's room.
