You May Need More or Less Potassium

Besides being linked to the potassium in your diet, potassium levels in your body are influenced by several factors, including kidney function, hormones, and prescription and over-the-counter medications.

People who take thiazide diuretics, often used to treat high blood pressure, may need more potassium. That's because thiazide diuretics promote potassium loss from the body. Steroids and laxatives also deplete potassium.

Other drugs used to lower blood pressure, including beta-blockers and ACE inhibitors, raise potassium levels in the body.

People with reduced kidney function may need to limit their daily potassium intake.

Ask your doctor or pharmacist about how all of the medications you take affect the potassium levels in your body, and if you need more, or less, of the mineral.
