How does pregnancy and childbirth cause stress urinary incontinence?
The pelvic floor is composed of muscle layers that act as a supportive hammock, stretching from the pubic bone to the end of the backbone. But pregnancy-related stresses — hormonal changes, pressure caused by the expanding womb, and childbirth itself (natural or caesarean) — can weaken the pelvic floor muscles, leading to an unsupported bladder neck and a lifetime of leaks.
The impact of a weak pelvic floor doesn’t end at the bladder. It can cause a loss of sexual sensation, poor posture, core strength weakness, and a lowered sense of self-confidence and wellbeing.
