What is hypokalemia, and how does it occur?


Hypokalemia or low blood potassium is not common, but can occur with prolonged diarrhea and/or vomiting (illness or eating disorder) or use of potassium-depleting diuretics. Signs and symptoms include muscle weakness, constipation, irritability, confusion, and (some studies suggest) insulin resistance. Hypokalemia can be very serious and cause irregular heart function, muscular paralysis, decreased blood pressure, and difficulty breathing.
