Non-Menstrual Bleeding

What Causes Unusual Vaginal Bleeding?

Unusual vaginal bleeding can have various causes, ranging in severity from 'needs attention' to 'generally fatal'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose unusual vaginal bleeding, we could:
  • Research the topic
  • Find a doctor with the time
  • Use a diagnostic computer system.
The process is the same, whichever method is used.

Step 1: List all Possible Causes

We begin by identifying the disease conditions which have "unusual vaginal bleeding" as a symptom.  Here are seven possibilities:
  • Adrenal Fatigue
  • Endometrial Cancer
  • Ovarian Cancer
  • Ovarian Cysts
  • Endometrial Hyperplasia
  • Fibroids
  • Endometriosis

Step 2: Build a Symptom Checklist

We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
occasional unexplained vomiting
hot flashes during period
early puberty onset
craving for salt
history of adult allergies
uterine fibroids
prednisone use
short-term cortisol use
inability to work under pressure
significant left iliac pain
painful deep penetration during sex
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of unusual vaginal bleeding:
Cause Probability Status
Ovarian Cancer 97% Confirm
Endometrial Cancer 26% Unlikely
Endometriosis 12% Unlikely
Fibroids 4% Ruled out
Ovarian Cysts 0% Ruled out
Endometrial Hyperplasia 0% Ruled out
Adrenal Fatigue 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate being menopausal or being postmenopausal, The Analyst™ will ask further questions including this one:
Abnormal bleeding. Do you have any vaginal bleeding that is not due to a menstrual period?$$$NOT linked to Metrorrhagia because abnormal bleeding is much more serious after menopause... conditions are linked individually instead
Possible responses:
→ Don't know
→ No
→ Occasionally, a few times per year
→ Frequently
→ Yes, it is constant or nearly constant
Based on your response to this question, which may indicate either no unusual vaginal bleeding or unusual vaginal bleeding, The Analyst™ will consider possibilities such as:
Endometrial Cancer

The most common sign of endometrial cancer is unusual bleeding from the vagina, especially bleeding that occurs after passing through menopause.

Endometrial Hyperplasia

Endometrial hyperplasia usually occurs after menopause, when ovulation stops and progesterone is no longer made.


Although endometriosis is more common in women who are still having periods, it does affect between 2% to 5% of postmenopausal women.


The growth of uterine fibroids is estrogen dependent, which means that fibroids tend to stop growing – and often shrink – after menopause.
