Potassium or Kalium (K) is present as potassium chloride (KCl) and potassium ions (K+) in the cells and fluids of our body. The total potassium content of a healthy individual is 50 mEq (milliequivalent) per kg of body weight. 98% of this potassium is present inside the cells, whereas only 2% is present in the interstitial fluid, and in blood at a concentration of 3.5 to 5.0 mEq/L.
Decrease in the potassium level of blood (hypokalemia) may occur due to abnormal distribution of potassium in the body. It may also be the result of increased excretion...
