Potassium is a mineral that our body needs to function properly. Our body does not produce Potassium naturally. Eating a balanced diet is the best source of potassium. Hence it is essential that we consume Potassium-rich foods. 

Can You Die from Low Potassium? Why is Potassium Important?

Potassium is an electrolyte. Now you might be wondering what are electrolytes and why are they necessary for our bodies. Electrolytes carry an electrical charge and are a type of mineral. When electrolytes are dissolved in our body, they activate cellular, muscular, and nervous system functions. It is particularly necessary for the proper functioning of heart muscle cells. The most important role that potassium plays is to maintain normal fluid levels in our cells.

Potassium ensures that extra sodium is removed from our body which in turn helps in maintaining blood pressure. 

Potassium helps in the below body functions:

  • Normal Blood Pressure
  • pH balance
  • Digestion
  • Helps in the flexing and contraction of muscles.
  • Arrhythmia
  • Water balance

What happens if you have low Potassium?

Hypokalemia is the medical term for a low level of potassium in your body. Normal Potassium level in the blood in adults ranges between 3.6 to 5.2 mmol/L. Hypokalemia can occur due to Potassium loss through vomiting, diarrhea, or laxatives intake. It may also be caused due to some medications or genetic conditions.

A potassium level ranging below 2.5 mmol/L is a fatal situation. This needs urgent medical attention. Potassium makes sure that your muscles, nerves, and heart are functioning properly. Potassium also affects your digestive tract and bones. If potassium deficiency continues, you may experience weakness in muscles, arrhythmias, i.e., abnormal heart rhythm, and in some cases even paralysis.
