Sodium and chloride are the major electrolytes lost in sweat and blood, and are therefore the minerals lost in greatest quantity when a person loses fluid through sweating or bleeding. Bicarbonate and sulfate are not major electrolytes lost through sweat and blood loss. Calcium and magnesium are not greatly affected by sweat and blood loss. While potassium and phosphate are also lost through sweat and blood loss, they are not lost in as great a quantity as sodium and chloride.
