Overactive bladder is a condition that causes a sudden and frequent urge to urinate, often leading to discomfort and anxiety. People with this condition may find themselves needing to go to the bathroom more often than usual, sometimes even experiencing leakage before they can reach a toilet. This can disrupt daily activities and affect quality of life. The exact cause of overactive bladder can vary, but it may be linked to issues with the bladder muscles or nerve signals. Treatment options include lifestyle changes, medications, and sometimes physical therapy to help manage symptoms and improve bladder control.
