The condition of acidosis can also cause hyperkalemia because the higher H+ concentration diffuses to the intracellular fluid, pushing K+ towards the extracellular fluid.
Hyperkalemia describes a potassium level in the blood which is higher than normal. Potassium is a vital substance to the function of nerve and muscle cells, including those of the heart. Blood potassium is normally 3.6 to 5.2 millimoles per liter.
