"Changes in bleeding are normal as you near menopause. There are also other common causes of bleeding in the years after menopause. The decline in your body's estrogen levels can cause tissues lining the vagina to become thin, dry, and less elastic. Sometimes this lining can become broken or easily inflamed and bleed. It can also become injured during sex or even during a pelvic exam.
Once you've reached menopause, though, you should report any bleeding that you have to your HCP. Uterine bleeding after menopause could be a sign of other health problems. Other things that can cause abnormal bleeding include:
* fibroids
* the use of birth control pills
* a hormonal imbalance
* non-cancerous growths in the lining of the uterus "

"Postmenopausal bleeding may be caused by:
* hormone (estrogen) replacement therapy
* hormone problems
* atrophy of the vagina, which is thinning and drying of the lining of the vagina
* polyps (small growths) in the uterus or on the cervix
* hyperplasia (enlarged cells) of the lining of the uterus
* infection of the cervix
* cancer of the uterus, cervix, or vagina
* some types of ovarian tumors
* anticoagulants (blood-thinner medicines)."

"Most of the time there is a reasonable explanation for a post-menopausal bleeding event, but any kind of irregular bleeding — particularly if you haven’t had a natural period for over a year — warrants investigation by your healthcare provider — just to rule out anything serious."
