I have often been faced with the question - to tell or not to tell people I interact with about my kidney disease.
In my previous job, I started out with people I already knew directly or indirectly. So they all knew. And since they knew, the new people who joined also got to know. So, in my old company, pretty much everyone knew about my kidney disease.
In my new company, after I was told I was hired, I sent an honest email to my prospective employers about my kidney disease, what it entailed and also about how I was confident that it would not interfere with my normal work. I am not sure, six months down the line, if that turned out to be entirely true. My health has affected my normal work. But not my kidney disease per se. Totally unrelated health issues. Which anyone could have had.
The rest of my co-workers however were not aware. So, they would often wonder what the ugly bulge in my left upper arm was! I would catch their eye moving to it during a conversation and then quickly move back to my eyes as I caught them doing it! I totally understand their curiosity. My fistula is quite big!
Eventually, the question did come however.
"Did you have some accident? What happened to your arm?"
I usually decide to tell the truth. My kidney disease is not something I am ashamed of. However, I won't tell unless I am asked. If I am asked, I will tell the truth.
