However, studies show that heart-related issues can also play a significant role. In heart failure (also called congestive heart failure), the heart doesn’t pump blood as effectively as it should. This leads to fluid buildup in the legs and lower body during the day. When you lie down at night, that fluid shifts back into circulation, reaches the kidneys, and increases urine production—prompting those frequent trips to the bathroom.

Research from various studies, including analyses of large populations, highlights that nocturia often appears in people with cardiovascular concerns.
