Potassium is a mineral that helps regulate fluid in the body and helps muscles and nerves to function properly. 

Deficiency of potassium in our body is called hypokalaemia, which may lead to dangerous consequences.

People with deficiency may experience paralysis, faint or experience irregular heart rhythms.

The normal levels of potassium range from 3.5 to 5.2 mEq/L (3.5 to 5.2 mmol/L).

Anything lower than 3 mEq/L (3 mmol/L) can be considered severe hypokalaemia.

Symptoms

  • Neurological

  • Gastrointestinal
