Web22 aug. 2024 · Lithium can cause hyponatremia by decreasing sodium reabsorption by the renal tubules, leading to sodium depletion. Therefore, it is essential for patients receiving Lithium treatment to maintain a normal diet, including salt, and an adequate fluid intake (2500 to 3000 mL) at least during the initial stabilization period. WebThese results indicate that changes in lithium reabsorption may be dissociated from the reabsorption of other cations. They are consistent with the hypothesis that FELi may …
