Is occasional bleeding from vaginal prolapse normal? if so, what might be the cause?

That is not good: Means the tissue is getting irritated or excoriated, make sure your gyn checks u to make sure it is not caused by something else and if u are a surgcial candidate u a=may want to consider having the prolapse fixed.

Possibly: It is best to see your doctor to be sure especially if you still have a uterus. Hope this helps.

Maybe: If you do not have a uterus and your prolapse extends outside of your vaginal opening, then it can become irritated and maybe even bleed some. If you have a uterus, there can be other issues that would need to be evaluated such as uterine cancer or pre-cancer, so see a women's health provider to be checked.
