hi, my mom is 72 years old and she tends to bleed when she does excercises or when she gets tired alot. she is very active by always doing things around the house and her excercises, she does have dyverticulities (not sure on the spelling) is there any cause for concern? she bleeds from the virgina, and when she pees, in addition she has also had a hystorectami and only tends to bleed when she excersices, why would that be?
