Overactive bladder (OAB) is a common condition marked by a sudden, frequent, and urgent need to urinate, often leading to accidents (urgency incontinence) and frequent nighttime urination (nocturia), significantly affecting quality of life. Causes include nerve problems, infections, excess caffeine/alcohol, constipation, or menopause, though sometimes the cause is unknown. Treatments range from behavioral changes (bladder training, Kegels, diet modification, weight loss) to medications, Botox injections, or surgery, and it's crucial to see a doctor to rule out other issues like UTIs or diabetes.
