Which type of incontinence is characterized by a sudden, strong urge to urinate?

Urge incontinence is defined by an involuntary loss of urine that occurs following a sudden, intense urge to urinate. This type of incontinence arises from an overactive bladder, which causes a sudden need to void, often accompanied by an inability to reach the bathroom in time. Individuals with urge incontinence experience frequent urination and may have episodes where they can’t control their urges, leading to leakage of urine.

For reference, stress incontinence involves leakage that occurs during physical activities that increase abdominal pressure, such as sneezing or exercise, rather than an overwhelming urge. Functional incontinence is linked to physical or cognitive impairments that hinder a person's ability to reach the bathroom in time, rather than an inherent issue with bladder function. Overflow incontinence is characterized by constant dribbling of urine due to a full bladder, often resulting from an obstruction or a weak bladder. Therefore, urge incontinence is the clear answer when considering the defining characteristic of a sudden, strong desire to urinate.
