Potassium is a mineral and electrolyte that is essential for the body to function properly. When levels of potassium (K) are out of balance, several issues can arise, such as hyperkalemia and hypokalemia, muscle cramps, low blood pressure, and changes in heart rhythm. Potassium levels change with sodium levels to keep muscles working properly throughout your body, especially your heart. As sodium levels rise, potassium levels decrease. And as sodium levels fall, the levels of potassium increase. Potassium is also affected by the hormone aldosterone, which is made by the adrenal glands.
