Diagnosing overactive bladder: what to know

Tell the clinician how often you pass urine, whether you wake at night, whether urgency causes leakage, and whether there is burning or pelvic pain. A bladder diary can show fluid intake, voiding times, urgency and leakage patterns. Urine testing may check for infection or blood, while an examination can assess pelvic organs, nerves and pelvic-floor function. Symptoms may overlap with infection, constipation, medicines, diabetes or bladder-emptying problems, so the diagnosis is not based on urgency alone.

Keep a diary for a few days if your clinician suggests it, and bring a list of medicines, supplements and drinks. Do not drastically restrict fluids without advice. If the initial assessment does not explain your symptoms, urodynamic testing may measure bladder pressure, flow and storage during filling and emptying. Treatment planning may include bladder training and pelvic-floor rehabilitation after the cause has been clarified.

Seek prompt medical care for blood in the urine, fever with urinary symptoms, pain in the side or back, inability to pass urine, new weakness or numbness, or sudden loss of bladder control. Urgency with severe pain or vomiting also needs assessment. These features may point to a problem requiring a different response from routine overactive-bladder care.

Ask which causes should be excluded, whether you need urine testing or a bladder diary, and what would make urodynamic testing useful. Discuss caffeine, constipation, medicines, pelvic-floor symptoms and whether bladder training is suitable for your pattern.
