What is it?

Hyperkalemia, or high levels of potassium in the blood, refers to levels higher than 5.2 millimoles per liter (mmol/L). Hyperkalemia may be caused due to acute kidney failure, chronic kidney disease, some medications, dehydration, Addison’s disease, red blood cells destruction, excessive use of potassium supplements and diabetes type 1. High levels of potassium could be dangerous and even lethal because it may lead to arrhythmias.
