What causes sneezing or coughing?

Stress urinary incontinence is caused by the relaxation of pelvic floor muscles and the weakening of urethral support. Stress urinary incontinence is more common in middle-aged women, and the incidence of stress urinary incontinence increases with age. Stress urinary incontinence occurs when coughing or sneezing causes a sudden increase in abdominal pressure, which causes compression of the bladder, relaxation of the pelvic muscles, and weak support for the urethra, resulting in leakage of urine. For mild stress urinary incontinence patients, symptoms can be relieved by pelvic floor muscle exercise. For severe stress urinary incontinence patients, surgery is required.
