A healthy pelvic floor functions as a muscular hammock that supports the bladder, urethra, and surrounding organs. When these muscles contract with adequate strength and timing, they compress the urethra during moments of increased abdominal pressure, such as coughing or lifting. Over time, pregnancy, childbirth, hormonal shifts, and chronic strain can weaken this hammock, reducing its ability to maintain that urethral seal. The American Urogynecologic Society identifies pelvic floor dysfunction as the central mechanism behind most cases of stress and mixed incontinence in adult women.
Once pelvic floor support declines, even small increases in abdominal pressure overcome the urethra's ability to stay closed, producing the classic leakage that happens with a sneeze, a jog, or a sudden laugh. In urge incontinence, the bladder muscle itself contracts at unpredictable times, overriding conscious control and creating that sense of racing to the bathroom. Many patients experience both patterns together, known as mixed incontinence.
Estrogen decline during perimenopause and menopause thins the tissues of the urethra and vaginal wall, further reducing structural support and nerve sensitivity. Addressing both the muscular and hormonal layers often produces stronger results than targeting either alone, which is why options such as Emsella Pelvic Floor Therapy are often paired with hormone optimization when clinically appropriate.
