Urinary tract infection: In case of urinary tract infection, the infection will stimulate the bladder and cause a strong urge to urinate, which may sometimes lead to urinary incontinence. 3. Pregnancy: Stress incontinence can occur in pregnant women when they exert themselves in the abdomen due to the pressure of the uterus on the bladder. 4. Childbirth: after a normal delivery, pregnant women can experience muscle relaxation of the pelvic floor muscles and sphincter muscles, which can lead to urinary incontinence. 5. Ageing: due to ageing, the level of estrogen decreases, which can lead to the relaxation of pelvic floor muscles, and the angle of the urethra and the bladder changes, which may cause urinary incontinence. 6. Prostatic hyperplasia: Prostatic hyperplasia may lead to difficulty in urination, causing urinary retention, which in turn may lead to urinary incontinence.
