Story at-a-glance
- New data from the largest clinical trial on this topic shows no improvement in symptoms, hospitalizations, or survival with fluid restriction in chronic heart failure patients
- Patients who drank more than the advised limit of 1,500 ml had no higher risk of death, hospitalization, kidney injury, or emergency interventions
- Fluid-restricted patients reported much higher thirst distress, which contributes to stress hormone release, reduced treatment compliance, and increased emotional strain
- Over-restricting both water and salt leads to dangerously low sodium levels, while getting enough potassium helps your kidneys manage hydration and prevent harmful fluid buildup
- Researchers recommend giving fluid goals based on your symptoms, medications, and how you feel — this allows you more control and fewer restrictions
