unfortunately every boss is different. Some dont care why you are out, others want to know and some feel they have a right to know.
Mcleaver's advice is good. Dont mention it further.
I was lucky because my boss asked me why i had a dr appt every 8 weeks (remicade) because he wanted to congratulate me on being pregnant LOL. I told him what I have and that was it. Now I just tell him I have a Dr appt and he doesnt ask or mention it.
