Explain about the Hypokalemia?
Normal serum K ranges from 3.5-5 mM/L. Hypokalemia or low plasma K levels can occur with a net shift of K from the plasma to the cells. This shift can occur in alkalosis. Overall depletion of body's K, which occurs in vomiting, prolonged fasting can also result in this shift. Mild hypokalemia results in weakness and muscle cramps and can cause arrhythmias in patients with heart diseases. Serve hypokalemia (<2.5 mM/L of K) can result in paralysis.
