Does sodium affect lithium levels?
Sodium balance (i.e. - salt intake) can have an impact on lithium levels. When there is sodium depletion (i.e. - hyponatremia or low sodium intake), lithium undergoes higher reabsorption, resulting in higher serum levels. Conversely, when there is high sodium intake, there is decreased lithium reabsorption, resulting in lower serum levels.
