yeah well the big one we're talking about here both help keep us from having unwanted pregnancies (you're fucking welcome) as well as mitigate symptoms some of us experience monthly, which no shit you don't understand because you've never experienced but come the fuck on, dude
also outside of bcp, chronic conditions often require meds to help keep them stable (e.g. ACE/ARB/diuretic for hypertension, statin for hyperlipidemia, metformin for diabetes, ACE/ARB as attn for nephropathy in diabetic patients, insulin, etc) where taking the meds help keep their health steady
