Overactive Bladder
A closer look at urinary urgency, frequent toilet visits and the approaches that can help you regain confidence in daily life.
A guide for patients and carers
What is an overactive bladder?
Overactive bladder, often shortened to OAB, describes a pattern of symptoms centred on a sudden need to pass urine that is difficult to put off. You may also go more often during the day or wake at night to use the toilet. Leakage can occur, but you can have OAB without leaking.
Symptoms and possible causes
Urgency may arrive with little warning. When urine leaks before you reach the toilet, this is called urgency urinary incontinence. These symptoms can make travel, work and sleep harder to manage.
The bladder may send a signal of fullness too early or its muscle may contract while it is filling. Sometimes there is no clear reason. Infection, certain medicines and neurological conditions can cause similar symptoms or contribute to urgency, so assessment matters.
How is it assessed?
A GP or specialist nurse will discuss your symptoms and general health. A urine sample can help check for infection. You may be asked to keep a diary for around three days, noting when and how much you drink, when you pass urine and any urgent episodes or leaks.
This record helps your clinician understand the pattern and plan treatment. Some people need a scan to check bladder emptying or specialist pressure and flow tests, particularly when initial treatment has not helped.
Everyday changes and bladder training
Ask about a fluid intake that suits your health. Drinking too little can make urine more concentrated and irritate the bladder. Reducing caffeine gradually and addressing constipation may help. Keep taking prescribed medicines unless your prescriber advises a change.
Bladder training is a supported, gradual programme to change the timing of toilet visits and manage urgency. A nurse or continence specialist can help set realistic goals using your diary. Pelvic floor training may also be appropriate after assessment. Improvement takes practice, so agree when to review progress.
Do not try to delay passing urine as a training exercise if you think you have an infection; seek advice about the new symptoms.
When more support is needed
If symptoms continue to affect your life, medicines may be offered. Your clinician should explain expected benefits, side effects and follow-up. Specialist options, such as bladder injections or nerve stimulation, may be considered when other approaches have not helped. These require an individual discussion of risks, including possible difficulty emptying the bladder.
Preparing for your appointment
Note which activities and times of day are most affected. Useful questions include: What might explain my urgency? Would bladder training suit me? How will we know whether treatment is helping? Tell your clinician if you develop pain, blood in the urine or symptoms of infection, rather than assuming these are OAB.
