Waking up occasionally to use the bathroom at night is normal, but if it happens frequently, it could be a sign of an underlying heart condition, according to research.
The medical term for needing to urinate multiple times at night is nocturia. While it is commonly associated with conditions like diabetes and an enlarged prostate, it may also be linked to certain heart diseases, particularly heart failure—a condition where the heart struggles to pump blood efficiently throughout the body.
The Connection Between Nocturia and Heart Health
According to the NHS, heart failure (also called congestive heart failure) doesn’t mean the heart has stopped working but rather that it requires additional support to function properly. It is a chronic condition that worsens over time and can affect people of all ages.
A study conducted in Japan involving 1,882 participants found that 1,295 of them needed to urinate at least once per night. Researchers discovered that these individuals had a 40% higher risk of hypertension (high blood pressure).
However, it’s important to consider that high sodium intake—a known contributor to hypertension—may also play a role. Japanese people typically consume around 10 grams of salt daily, which is significantly higher than the global average of 4 grams.
Excessive salt intake and high blood pressure are major risk factors for cardiovascular diseases, heart failure, and strokes.
Nocturia, Sleep Disruptions, and Heart Disease
Some studies suggest that the link between nocturia and heart failure is more complex. Frequent nighttime awakenings can disrupt sleep quality, preventing the body from getting the restorative rest it needs. Poor sleep has been associated with an increased risk of heart disease, as well as other health issues like diabetes and obesity.
When to Seek Medical Advice
If you experience nocturia regularly, it may be worth consulting a doctor to determine the underlying cause. Addressing it early could help prevent potential heart-related complications and improve overall health.
