Hypokalemia (low Potassium)

What Is Hypokalemia? Hypokalemia is an electrolyte imbalance and is indicated by a low level of potassium in the blood. The normal adult value for potassium is 3.5-5.3 mEq/L. Potassium is one of many electrolytes in your body. It is found inside of cells. Normal levels of potassium are important for the maintenance of heart, and nervous system function. What Causes Hypokalemia? One way your body regulates blood potassium levels is by shifting potassium into and out of cells. When there is a breakdown or destruction of cells, the electrolyte potassium moves from inside of the cell to outside of the cell wall. This shift of potassium into the cells causes hypokalemia. Trauma or insulin excess, especially if diabetic, can cause a shift of potassium into cells (hypokalemia). Potassium is excreted (or "flushed out" of your system) by your kidneys. Certain drugs or conditions may cause your kidneys to excrete excess potassium. This is the most common cause of hypokalemia. Other causes of hypokalemia include: Increased excretion (or loss) of potassium from your body. Some medications may cause potassium loss which can lead to hypokalemia. Common medications include loop diuretics (such as Continue reading >>

    Insulin results Hypokalemia just by increasing the activity of H*K ATPase pump. So insulin only shifts the K+ from the extracellular compartment to the intracellular compartment, it doesn't decrease the total K+ content of the body........remember it......that's why during management of Hyperkalemia 1st initial therapy is done by giving Insulin + Glucose combination which usually needs 30 minutes to come into action........Hope it helps
