## Sodium 136-145 mEq/L regulates water balance, controls extracellular fluid volume, increases cell membrane permeability, stimulates conduction of nerve impulses and helps maintain neuromuscular irritability, controls contractility of muscles. Most abundant electrolyte in the body. Major source is from the diet; frequently it must be limited. ### Signs and Symptoms - hyperreflexia, muscle twitching, and tremors - neurologic manifestations such as a headache due to swelling of brain cells. - anorexia, nausea, diarrhea and vomiting - dilutional hyponatremia happens with: - SIADH, heart failure, liver cirrhosis, nephrotic syndrome ### Treatment Oral fluids are restricted to restore the fluid balance and therefore the sodium level in the blood.
