Bleeding after sex in perimenopause and after menopause
Bleeding after sex is most often caused by thin, fragile vaginal and cervical tissue as estrogen falls, and it responds well to treatment. It is nonetheless always examined, because it is also a potential sign of cervical cancer and of polyps, and an examination plus up-to-date cervical screening settles the question quickly. It should never be assumed to be dryness without being looked at, and never watched and waited on after menopause.
Why it happens
As estrogen falls, the vaginal and cervical lining becomes thinner, less elastic and less well supplied with blood, and natural lubrication decreases. Thin tissue under friction splits at the surface, and the small amount of bleeding that follows is usually pink or light red and brief.
The cervix is also affected, and the area where two types of cell meet on its surface becomes more prone to bleeding on contact.
This explains the common story: new discomfort during sex over several months, then light bleeding afterwards.
Why it is examined anyway
The benign explanation is the usual one, and it is still not a reason to skip an examination.
Bleeding after sex is one of the recognised symptoms of cervical cancer, and it can also be caused by cervical polyps, which are benign but usually removed. Both are found by looking, which takes minutes.
The second reason is specific and important: if you are postmenopausal, bleeding after sex is postmenopausal bleeding. It falls under the same rule as any other bleeding after twelve months without a period, and a plausible mechanical explanation does not exempt it.
What the assessment involves
An examination of the vagina and cervix, a check that cervical screening is up to date, usually swabs to exclude infection, and in postmenopausal women an assessment of the womb lining, often by ultrasound.
Where thin tissue is the cause, it is visible on examination, which is the fastest route to the right treatment rather than an ordeal to be endured.
What helps once it is explained
Local vaginal estrogen treats the underlying tissue change directly, and it is the treatment with the clearest effect here. It takes weeks rather than days, and benefit continues only while it is used.
Vaginal moisturisers used regularly, and lubricants used during sex, have a genuine role and work alongside rather than instead. Lubricant addresses the friction; it does not restore the tissue.
When to see someone
Book for any bleeding after sex, including a single episode and including when you are confident it is dryness. Say so when you book if you are postmenopausal.
Check your cervical screening is current — this is the symptom for which it matters most.
