Overactive bladder occurs when the bladder muscle contracts periodically and suddenly. This leads to the strong and sudden urge to urinate.
Overactive bladder is characterized by two main symptoms:
- urinary frequency: going to the bathroom more than 8 times in 24 hours
- nocturia: needing to urinate two or more times at night
- urinary urgency: frequent, sudden, strong urges to urinate with little or no chance to postpone urination
Your symptoms may be triggered by certain cues, such as hearing running water or arriving home.
