Why is potassium important for the body?

Potassium is vital for maintaining cellular function, regulating heartbeats, and balancing fluids in the body. It helps muscles contract, nerves transmit signals, and cells maintain proper pressure. Potassium works with sodium to manage blood pressure and supports kidney and adrenal gland health. Imbalances in potassium levels can lead to symptoms like weakness, irregular heart rhythms, or even life-threatening complications. Regular monitoring through a potassium test ensures that levels remain within the normal range, particularly for individuals with chronic conditions like kidney disease, heart disease, or hypertension.
