Electrolyte Imbalance

Electrolytes are substances that help metabolism in the body, such as sodium, potassium, magnesium, chloride, and calcium. Because thiazide diuretics block reabsorption of electrolytes, body is at risk for depletion of some electrolytes. Potassium depletion is especially a great concern because hypokalemia, a low level of potassium in the body, can cause fatal dysrhythima. Fatal dysrhythmia ia dangerous condition caused by extremely irregular heart beat. Potassium supplements or foods rich in potassium is recommended with the use of thiazide diurectis to prevent hypokalemia.

Other potential electrolyte imbalances are yyperchloremic alkalosis (a metabolic disorder resulting from an increase in blood bicarbonate level secondary to loss of chloride from the body), hypomagnesemia (abnormally low level of magnesium in blood), and hyponatremia (abhormally low level of sodium in blood).
