How is sodium retention in ESRD typically treated?

In end-stage renal disease (ESRD), the kidneys are severely compromised in their ability to filter out waste products and excess substances from the body, leading to sodium retention among other issues. This sodium retention can contribute to fluid overload, hypertension, and other complications.

The treatment for sodium retention in this context primarily involves the use of diuretics, specifically loop diuretics. Loop diuretics work by inhibiting the reabsorption of sodium and chloride in the loop of Henle within the nephron and promote the excretion of sodium, water, and other electrolytes. This process effectively eliminates excess fluid from the body, helping to manage the symptoms associated with fluid overload, such as edema and hypertension.

While adjusting dietary sodium is important and may be part of an overall management strategy, in cases where sodium retention is significant, the administration of diuretics is often more critical to quickly address the imbalance. Increasing fluid intake contradicts the need to manage fluid overload, and administering potassium supplements is not relevant for the specific issue of sodium retention in ESRD, as potassium levels would need to be closely monitored given the impaired renal function. Thus, the use of loop diuretics as a method to eliminate excess sodium and fluid is a key
