This creates a potential vicious cycle: Heart-related fluid issues cause nocturia → nocturia disrupts sleep → poor sleep worsens blood pressure control and cardiovascular strain → more nocturia.
Studies on patients with stable heart failure show that those with frequent nocturia report more daytime fatigue, sleepiness, and reduced function. Addressing sleep interruptions could break this loop, but it
