What is Hypokalemia?
Hypokalemia occurs when the potassium level in the blood falls below 3.5 mEq/L. Potassium is
essential for normal muscle contractions, nerve signaling, and maintaining a steady heart rhythm.

Think of Potassium as:

The body's electrical battery.
When potassium is low, muscles become weak, the digestive system slows down, and the heart
may develop dangerous rhythm changes.
