Document Summary
Key electrolytes include: sodium, potassium, calcium, magnesium, chloride. The electrolyte levels are influenced by osmolality of the intra, extra and transcellular water. However, in excess amounts the electrolytes either lost or retained, depending on the body water volume. The body losses its ability to maintain fluid balance. Our electrolytes are lost in the excretory wastes of the body and sweating on a daily basis. The amount of sweat depends on the 6 factors previously mentioned. Remember, how much the athlete sweats or appears to s(cid:449)eat isn"t the only fa(cid:272)tor in ele(cid:272)trolyte loss. When we sweat, we lose extra cellular fluids and along with those we lose the major electrolytes (na and cl) and minor components (ca and k). When we compare sweat to plasma it is hypo-osmolar i. e. hypotonic. This means that if dehydration occurs (water volume decreases) and the concentration of electrolytes increases causing hypernatremia.
