11 Everyday Habits That Are Quietly Draining Your Blood Pressure-Regulating Potassium

5. Using some prescription diuretics or steroids without monitoring

Certain blood-pressure medicines called thiazide diuretics commonly lower potassium by increasing urinary excretion. Other drugs, including some steroids, can also change potassium levels in differing ways. This doesn't mean you should stop medication; rather, it highlights the importance of monitoring. Ask your clinician whether your prescriptions affect potassium and whether routine blood tests are needed. If your care plan allows, simple dietary additions such as potassium-rich vegetables or a clinician-approved supplement can counter low levels. Never change prescribed medication on your own. Work with your healthcare team to keep blood pressure controlled and potassium balanced safely.

6. Excessive caffeine from energy drinks and high-dose supplements

High intakes of caffeine, especially from energy drinks or concentrated supplements, can increase urine output and sometimes contribute to small losses of potassium. That effect may be modest for casual caffeine users, but frequent high doses paired with poor diet or dehydration can matter. Replace one energy drink a day with tea or a plain coffee plus a potassium-rich snack, like a small banana or handful of nuts. Also be mindful of hidden caffeine in supplements and preworkouts. If you notice jitteriness, sleep disruption, or changes in blood pressure, cutting back and checking in with a clinician is a wise step.
