Dysfunction: It interferes with the muscles ability to contract because it alters the electrolyte balance across the muscle memberane. You have to have the right balance of potassium and other electrolytes for the contractile elements of the muscle to be able to contract which is what gives you movement and strength.

A 47-year-old member asked:

Does hypo or hyperkalemia cause muscle weakness?

3 doctor answers13 doctors weighed in
Dr. Kevin Griffiths
Specializes in Nephrology and Dialysis
Hypo: Potassium is needed to help muscle function. Without enough potassium, there is a change in the conduction of cells within a muscle. This change can lead to cramping, weakness and even heart arrythmias. People who have poor diets or who take diuretics "water pills" can develop hypokalemia more often.
