Potassium Deficiency
Potassium is a mineral that is essential for all of the body's functions.
It helps your nerves, muscles and heart function properly, and also helps move nutrients and waste around your cells.
Foods that have lots of potassium include:
Avocados.
Bananas.
Beans and peas.
Bran.
Dark leafy greens.
Milk.
Oranges.
Peanut butter.
Potatoes.
Spinach.
Tomatoes.
Potassium deficiency (hypokalaemia) is when a person has abnormally low levels of potassium in their body. Some people with potassium deficiency don't experience any symptoms, but others will notice muscle weakness, muscle cramps and an abnormal heart rhythm (arrhythmia).
Potassium deficiency is treated with supplements.
