Long-term use of diuretics in patients with kidney disease can lead to significant risks, particularly electrolyte imbalances and dehydration. Diuretics work by promoting the excretion of sodium and water through the kidneys, which can effectively reduce fluid overload and lower blood pressure. However, as diuretics increase urine production, they also enhance the risk of losing important electrolytes such as potassium, sodium, and magnesium.

These imbalances can have serious consequences. For example, hypokalemia (low potassium) can lead to cardiac arrhythmias, while hyponatremia (low sodium) can cause neurological issues. Additionally, excessive fluid loss can result in dehydration, which can further compromise kidney function and overall health.

Patients who are on long-term diuretic therapy must be closely monitored for these potential complications to manage and mitigate risks effectively. Regular blood tests may be necessary to check electrolyte levels and ensure that fluid balance is maintained. Thus, understanding these risks is crucial for nephrology nurses when providing care and recommendations for patients with kidney disease.
