Was told have dropped bladder but not prolapsing. what is the difference?

Here are some...: Bladder drop to prolapse all results from pelvic floor muscle weakness, which is chiefly related to childbirth, aging, etc., but presents on its different stage of weakness. At its early stage, bladder drop is visible but still inside vaginal outlet; at its later severe stage, bladder/vaginal wall becomes obviously visible out of vagina. In short, it is the same at different stage of full spectrum
