Urinary Incontinence Practice Test

Pregnancy increases urinary incontinence risk because of both hormonal and mechanical changes that together weaken the pelvic floor and bladder control, with recovery after delivery varying between people. Hormonal shifts—higher levels of progesterone and relaxin—toster pelvic tissues and the bladder neck, reducing urethral support and potentially increasing bladder irritability. At the same time, the growing uterus raises intra-abdominal pressure and stretches the pelvic floor muscles and connective tissues, causing urethral hypermobility and poorer bladder support. This combination makes leakage more likely during activities that raise pressure, such as coughing, sneezing, or lifting, and can also affect urgency sensations.

Postpartum recovery varies widely depending on factors like the extent of pelvic floor stretching or injury, birth method, and individual healing. Because of these dynamics, stress incontinence is particularly common during pregnancy, reflecting the mechanical load on a weakened pelvic floor. Other options that suggest only hormonal effects, or that risk is reduced, or that urge incontinence is eliminated, don’t fit the full picture, since both hormones and mechanics contribute and not all symptoms resolve uniformly after birth.
