Nocturia is the most common and under-recognized urinary symptom, experienced by the majority of older people and increasing in prevalence with advancing age. It is associated with a range of debilitating effects including sleep disturbances, falls and instability, depression, and social isolation, yet it is accepted by many as a natural consequence of ageing. However nocturia, like most other lower urinary tract symptoms, is responsive to a range of simple lifestyle advice and behavioural interventions that may be delivered by nurses. This article calls for a raised awareness of this 'silent condition' to enable nurses to recognize nocturia, identify its impact on individuals and initiate and deliver intervention to improve the health and well-being of older people.
