Is this normal language to describe a health issue? Could be triggering to read

I'm speechless. Each post I read, feels like I wrote myself. I don't know where to even start. Please bear with me.

I'm low contact with my elderly parents, which is made easier because they decided to move away just after their grandchildren were born. Currently one parent is going thru a very significant health issue, and I'm struggling knowing with how much contact to have in order to kind of keep abreast. The other parent is very angry about providing health care for their spouse.

The next bit may be triggering to read.

In a phone call the sick parent talked to me with an update about (I'm sorry I can't do a spoiler on my phone) their, let's say, continence issues. I was told...

<So yeah, things were going great, I was pissing so great I could hit a target on the wall from 4 feet away, but now ...>

I felt so disgusted having to hear this, and it was happened so fast into the conversation that I had no chance to even stop it

Is this a normal conversational tack to describe this, am I overreacting?

I'm so overwhelmed and confused by so much at the moment

Thank you
