Overactive Bladder
Overactive bladder is a sudden, strong urge to pass urine that is hard to put off, often with frequent trips to the toilet and waking at night to go. Some people also leak before they reach the toilet.
Key points
- The core sign is urgency: the need comes on fast and feels urgent.
- The symptom pattern, urine testing, retention or kidney involvement, pregnancy and recurrence all affect what care is appropriate.
- Pelvic floor exercises help many people regain control.
Similar urinary symptoms can have different causes, so catalogue matches should not replace urine testing or clinical assessment when indicated.
How it shows up
Alongside it, you may go more than eight times a day, wake once or twice a night, or have small leaks when an urge hits. Triggers like cold weather, running water, or arriving home can set it off. Bladder irritants matter too.
How it is treated
First steps are practical: spacing fluids sensibly, easing off caffeine and alcohol, and bladder training to stretch the gap between visits. When that is not enough, medicines settle the bladder muscle. Antimuscarinics such as solifenacin, tolterodine, oxybutynin, and darifenacin reduce unwanted contractions, while mirabegron works a different way to relax the bladder as it fills.

When to see a doctor
See a doctor if symptoms are disrupting sleep, work, or daily life, or if changes appeared suddenly. Get checked promptly for blood in the urine, pain or burning when passing water, fever, or sudden trouble emptying the bladder, as these point to something other than overactive bladder.
When to seek urgent care
Seek prompt care for fever or shaking chills, pain in the side or back, vomiting, visible blood, inability to pass urine, pregnancy with urinary symptoms, or a child who appears unwell.
