How does estrada e cream help prolapsed bladder?

Stronger vag. wall: Estrogen cream is frequently use with a pessary support (from within the vagina, holding up the bladder) to prevent infection and vaginal wall erosion. THe latter makes bladder prolapse much worse. Estrogen helps strengthen and maintain muscles in the top of the vagina, which also supports the bladder and prevents further prolapse. It may reverse it but that is not definitive.

Doubtful: I understand this is an estrogen cream? This may lessen your vaginal symptoms of discomfort, pressure, dryness, however, it probably does not help to reduce the prolapsed bladder, but your handling of the symptoms may improve

None: The harmone cream helps the lining of the Vagina to become normal, These are commonly used in cases of prolapse when lining of the vagina is thin and fragile. But it does not lift the bladder up, if that is what you are expecting.
