Symptom 9. Increased Urination at Night: An Unusual Connection
Increased urination at night, or nocturia, is another unusual symptom of chronic heart failure. While it might seem unrelated, this symptom is a direct result of the body’s response to fluid accumulation, a common occurrence in chronic heart failure.
So, how does heart failure lead to increased urination at night? During the day, the fluid accumulated in your legs and lower body is drawn back into the bloodstream due to gravity when you lie down to sleep. Your kidneys process this additional fluid, resulting in an increased need to urinate during the night.
Notably, nocturia related to heart failure is different from regular nighttime urination. The frequency is typically higher, with individuals waking up multiple times during the night to urinate. This symptom can disrupt sleep, leading to daytime fatigue and tiredness. (9)
