Overactive Bladder (OAB) and Urinary Symptoms in Women
Overactive bladder is a condition characterised by urinary urgency, often with increased frequency and nocturia. Some women may also experience urge incontinence.
Overactive bladder is a symptom-based diagnosis. It is made after excluding other causes such as urinary infection, bladder stones, neurological conditions, or structural abnormalities.
These articles are intended as educational sources, not diagnostic nor taking place of a proper medical assessment. If you need help, please book an appointment with one of our GP’s.
Understanding Urinary Symptoms in Women
Urinary symptoms in women are common and may have several possible causes. While overactive bladder describes urgency and frequency without infection, similar symptoms can arise from other conditions.
Common urinary symptoms include:
- Urgency, a sudden strong need to pass urine
- Increased daytime frequency
- Waking at night to pass urine
- Leakage before reaching the toilet
- Burning or discomfort when passing urine
- Leakage when coughing or exercising
Possible causes include:
- Overactive bladder
- Urinary tract infection (UTI)
- Pelvic floor weakness
- Genitourinary syndrome of menopause
- Bladder irritation from caffeine or certain medicines
- Neurological conditions
- Pregnancy or postnatal changes
Because symptoms overlap, assessment is important before assuming a diagnosis.
Urine testing, medication review, and discussion of pelvic or hormonal symptoms may be needed to guide management.
What Is Overactive Bladder?
Overactive bladder typically involves:
- Sudden strong urge to pass urine
- Frequent urination during the day
- Waking at night to pass urine
- Leakage before reaching the toilet
It differs from stress incontinence, which occurs with coughing, laughing, or exercise.
Why Does It Happen?
Possible contributing factors include:
- Hormonal changes during menopause
- Bladder muscle overactivity
- Pelvic floor weakness
- Neurological conditions
- Caffeine or fluid intake patterns
After menopause, reduced oestrogen can affect bladder and urethral tissue, contributing to urinary urgency and irritation.
First-Line Management
Treatment often begins with non-medication approaches:
- Bladder training
- Pelvic floor physiotherapy
- Fluid timing adjustments
- Reducing caffeine intake
These measures may significantly improve symptoms.
Pelvic Floor Physiotherapy
Specialist pelvic floor physiotherapy can significantly improve bladder control through targeted exercises, bladder training techniques, and expert guidance tailored to your needs.
Our experienced physiotherapists work with women experiencing overactive bladder, stress incontinence, and other pelvic health concerns.

If symptoms persist and affect quality of life, medication may be considered.
Common options include:
Antimuscarinic medicines
These reduce involuntary bladder muscle contractions.
Examples include:
- oxybutynin
- solifenacin
- tolterodine
Possible side effects:
- dry mouth
- constipation
- blurred vision
Beta-3 agonists
These relax the bladder muscle.
Example:
- mirabegron
Blood pressure monitoring may be required.
Vaginal Oestrogen and Menopause
In postmenopausal women, local vaginal oestrogen may improve urinary urgency and irritation associated with genitourinary syndrome of menopause.
Local treatment usually has minimal systemic absorption.

When Further Assessment Is Needed
Before starting medication, assessment may include:
- Urine testing
- Review of infection history
- Pelvic symptom review
- Medication review
- Consideration of blood tests where relevant
Red Flags
Seek medical review urgently if you experience:
- blood in urine
- unexplained weight loss
- persistent pelvic pain
- recurrent urinary infections
- difficulty emptying bladder
Sudden inability to pass urine requires urgent assessment.
When to Contact a GP
You should consider contacting a GP if:
- you are unsure whether symptoms could be infection
- urgency or frequency disrupt daily life
- leakage becomes more frequent
- symptoms worsen after menopause
- treatment causes side effects
