Overactive bladder is characterized by a sudden and frequent urge to urinate. People with this condition may experience urinary urgency, where they feel the need to urinate immediately, often resulting in involuntary urine leakage. An overactive bladder can significantly impact a person's quality of life and may be caused by various factors, including bladder muscle overactivity and nerve problems. Treatment options range from lifestyle changes and behavioral therapies to medications and, in some cases, medical procedures.
