What should you know about nighttime overactive bladder?

Overactive bladder involves a sudden urge to pass urine that can be difficult to defer, with or without leaking urine. Waking to urinate may also relate to evening fluids, caffeine, alcohol, medicines, constipation, urinary infection, pregnancy, diabetes, sleep problems or fluid shifting from the legs when lying down.

A clinician may ask about urgency, leakage, burning, thirst, bowel symptoms, ankle swelling and sleep. A urine test and a bladder diary can help separate bladder storage symptoms from increased urine production at night.

Record drinks, toilet visits, urgency, leakage and sleep for several days to show the pattern. Avoid large drinks close to bedtime while keeping daytime hydration steady, and reduce evening caffeine or alcohol if they trigger urgency. Treat constipation and empty your bladder before bed. Do not sharply restrict fluids without medical advice.

Bladder training uses planned toilet visits and gradual delays to build better control; a clinician or continence specialist can tailor it. Pelvic floor exercises may also help some people. If symptoms persist, urodynamic testing may be considered to examine how the bladder stores and releases urine.

Arrange a review if night-time urination is new, worsening, repeatedly breaks sleep, or comes with leaking urine. Seek prompt care for burning urine, fever, back or side pain, visible blood, inability to pass urine, marked thirst, or sudden leg swelling and breathlessness.

Ask: Could a medicine, infection or sleep problem be contributing? Should I complete a bladder diary? Would bladder training or pelvic floor therapy suit me? When would urodynamic testing add useful information?
