The pelvic floor is a hammock of muscles and connective tissue that supports the bladder, urethra, and surrounding pelvic organs. When these muscles weaken or become uncoordinated, the bladder loses its support system and the urethra can no longer fully close under pressure. The result is leakage, urgency, or both. The American Urological Association recognizes pelvic floor weakness as a primary contributor to stress incontinence in women and post-prostatectomy incontinence in men.
Stress incontinence occurs when increased abdominal pressure from coughing, laughing, sneezing, or exercise overcomes a weakened pelvic floor. Urge incontinence, often called overactive bladder, happens when the bladder muscle contracts involuntarily, creating sudden, intense urges. Many patients experience mixed incontinence, a combination of both. In men, urinary incontinence frequently follows prostate surgery and responds well to pelvic floor strengthening.
Hormonal changes also play a role. Declining estrogen during perimenopause and menopause thins the urethral lining and reduces pelvic tissue elasticity. For some patients, addressing these contributors with hormone replacement therapy alongside pelvic floor strengthening produces meaningful improvement.
