From the Guidelines
To manage fluid overload, start by restricting sodium and fluid intake while taking diuretics as prescribed by your healthcare provider, with loop diuretics like furosemide being the preferred first-line treatment, as recommended by the most recent guidelines 1. The management of fluid overload, or hypervolemia, is crucial to prevent complications and improve patient outcomes.
Key Considerations
- The initial approach to managing fluid overload involves the use of intravenous loop diuretics, such as furosemide, to reduce morbidity and relieve symptoms of congestion 1.
- The dose of furosemide should be limited to the smallest amount necessary to provide an adequate clinical effect and should be modified according to previous renal function and previous dose of diuretics 1.
- For patients with resistant cases of fluid overload, combination therapy with different diuretic classes may be needed, such as adding a thiazide like hydrochlorothiazide or a potassium-sparing diuretic like spironolactone 1.
Monitoring and Adjustments
- Regular monitoring of urine output, signs and symptoms of congestion, electrolytes, kidney function, and blood pressure is essential to adjust the diuretic dose and avoid potential complications such as hypotension, hypokalemia, and renal dysfunction 1.
- Patients should be educated to monitor their weight daily and report any symptoms of worsening fluid overload, such as increased swelling, shortness of breath, or rapid weight gain.
Additional Measures
- Elevating the legs when sitting and wearing compression stockings can help reduce peripheral edema.
- For severe cases of fluid overload, ultrafiltration or dialysis may be necessary.
- The underlying cause of fluid overload, such as heart failure, kidney disease, or liver cirrhosis, must also be addressed for effective long-term management.
Treatment Goals
- The treatment goal of diuretic use is to eliminate clinical evidence of fluid retention, using the lowest dose possible to maintain euvolemia 1.

From the Research
Management of Fluid Overload
To manage fluid overload, several strategies can be employed, including:
- Diuretic therapy: Diuretics, such as furosemide, metolazone, and spironolactone, are commonly used to treat fluid overload in patients with heart failure 2, 3.
- Aquaretic therapy: The addition of an aquaretic-like vasopressin antagonist, such as tolvaptan, may enhance diuresis further 2.
- Optimization of diuretic intervention: Maximizing water and sodium excretion through diuretic therapy is a critical therapeutic target in patients with heart failure 4.
- Renal replacement therapy: When diuretic therapy fails to relieve congestion, renal replacement therapy may be necessary to remove excess fluid 4, 3.
- Sodium restriction: Sodium restriction has been believed to be indispensable in managing fluid overload during acute decompensated heart failure, but recent data suggest that small amounts of hypertonic saline solution with high-dose furosemide may produce improvement in hemodynamic and clinical parameters without severe adverse effects 5.
- Nurse-led programs: Nurse-led programs that incorporate objective fluid volume assessment, structured patient education, and action plan coaching may improve blood pressure and self-management in patients with chronic kidney disease and fluid overload 6.
Monitoring and Adjustments
Monitoring and adjustments are crucial in managing fluid overload, including:
- Close supervision by a team of cardiologists and nephrologists 2.
- Regular assessment of serum sodium, potassium, and creatinine levels 2.
- Monitoring of urine output and weight loss 2.
- Adjustment of diuretic therapy based on patient response and clinical goals 3.
- Consideration of the interplay between the heart, kidney, and lung in volume regulation and management 4.
