Modern medical science! Hysterectomy and stents that require anti rejection meds all within a month!

I don’t understand this. Why does she need anti rejection meds for stents or a hysterectomy? She also didn’t answer my question.

I don’t need them for my 3 stents and the mother in law didn’t need them for her hysterectomy that was done decades ago.
