Blood pressure medicines lower pressure but don't fix the root cause of why it was high in the first place.

Blood pressure medications are more effective when combined with metabolic improvements (e.g., weight loss, whole-food diet, exercise, sleep) that restore hormonal regulation of sodium and vascular function.

Cutting down on salt helps lower your blood pressure, even if you're already taking medicine for high blood pressure — so salt reduction adds extra benefit on top of your meds.
