Hello this is Dr. Salama MD,
There are a few potential causes for bleeding years after a hysterectomy:
Vaginal dryness, a common side effect of hysterectomy, makes vaginal tissues thinner and more prone to bleeding from sexual intercourse or other irritations.
One can even develop fissures, or cracks, in dry vaginal tissues that cause bleeding.
“Mini periods” can continue if you had a subtotal hysterectomy and the cervix was retained. Essentially, a tiny portion of uterus remains, and as the ovaries continue to cycle, that small piece of uterus continues to shed lining just as before.
Regardless of the cause, I would see a gynecologist who could perform a pelvic exam and/or pap smear if warranted and prescribe the appropriate treatment for you.
Let me know if you have any other questions.
If not, please don't forget to leave a positive rating as that's the only way I get credit for answering your question.
