Sodium deficiency, condition in which sodium is insufficient or is not utilized properly. Sodium is an element that functions with chlorine and bicarbonate to maintain a balance of positive and negative ions (electrically charged particles) in body fluids and tissues. The body receives sodium primarily in the form of table salt (sodium chloride). Sodium, the principal extracellular ion, has the property of holding water in body tissues. In persons with circulatory problems, excess sodium may result in edema, or retention of water in the body. On the other hand, too little sodium in the diet disturbs the tissue-water and acid-base balance that is important to good nutritional status.
