Health risks to be aware of if you wee in the showerYou might suffer a weakened pelvic floor, bacterial infection or increase your risk of incontinence. Abbas said: “Weeing in the shower can increase your risk of a weakened pelvic floor, especially for people who have existing pelvic floor issues or poor posture. As a result, you may push or strain to empty, which puts downward pressure on the pelvic floor. This action can push down on the pelvic organs, causing stress or gradually weakening the pelvic floor muscles. Most men will not be affected by this, unless they have pre-existing pelvic floor issues.
