Potassium deficiency, or Hypokalemia, is a condition in which a person does not get enough potassium for their body. It can be due to a poor diet or loss due to diarrhoea or vomiting. Potassium deficiency can result in medical conditions like high blood pressure, constipation, muscle weakness, and fatigue.
Potassium is an important mineral that plays a number of roles in our body. Our body derives it primarily from our diets. Its main functions are:
Small changes in levels of potassium can affect our bodily functions. Potassium maintains the electrical activity in the cells in our bodies. When this level drops, it affects the cells high in electrical activity - like nerves, muscles, and the heart.
Potassium deficiency is characterised by potassium levels lower than 3.6mmol/litre.
Although we source most of our potassium from our diet, a low-potassium diet is hardly ever the reason for a deficiency.
More often than not, potassium deficiency occurs due to loss from the Gastrointestinal tract (GI) or the kidney
