When potassium levels rise beyond 5.0–5.5 mEq/L, it is generally referred to as hyperkalemia. This condition can cause heart attacks, muscle weakness, or paralysis. Tap to know the causes!

Pseudohyperkalemia

They are artificially produced increases in blood potassium levels, often brought on by issues with sample processing or collection.

Metabolic acidosis

A process in which, due to excess production of acid, there is movement of potassium ions from cells into the bloodstream.

Red cell transfusion

Due to red blood cell transfusion, potassium is released from the cells into the blood and hence increases serum potassium levels.

Succinylcholine

Potassium moves out of the cell due to succinylcholine, a muscle relaxant used as an adjunct in anaesthesia, leading to a rise in serum potassium.

Arginine hydrochloride

By affecting the kidneys and potassium balance, an amino acid supplement may raise potassium levels.

Kidney dysfunction

The cause for impaired renal clearance of potassium, leading to its accumulation in the blood.
