![]() It is usually caused by an imbalance between night-time urine production and bladder capacity. Nocturia has recently been recognised as a separate medical condition rather than a symptom of another disorder. However, in many cases of nocturia, the average volume of urine produced during the night is greater than the amount the bladder can hold. This limits the need to empty the bladder during sleep. Nocturia – a medical conditionĪt night, the body naturally increases the release of an antidiuretic hormone, called vasopressin, to reduce the volume of urine produced to about a third of the total daily output. Being woken during this phase of sleep has the biggest impact on the daytime performance of an individual. ![]() The most important and deepest form of sleep occurs early on in the night, generally during the first three to four hours. Five or six hours of undisturbed sleep are far more beneficial than ten hours of disturbed sleep. It is not the overall length of sleep that matters, but an adequate length of uninterrupted sleep. Sleep serves many vital functions such as conservation of energy, rehabilitation, repair and metabolism, but more significantly, it enhances cognitive function and extends life expectancy. Recent figures show that nearly 40 million adults in Europe regularly have their sleep disrupted by the need to pass urine, causing daytime tiredness and, subsequently, health and psychological problems. Nocturia (or the need to wake up at least once a night to urinate) is one of the most common causes of sleep loss affecting more than half of men and women over the age of 50.
