What Causes Bleeding Between Periods?

Bleeding between periods can have various causes, ranging in severity from 'troubling' 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 bleeding between periods, 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 "bleeding between periods" as a symptom.  Here are eight of many possibilities (more below):
  • Hypothyroidism
  • Adrenal Fatigue
  • Low Progesterone
  • Endometrial Hyperplasia
  • Endometrial Cancer
  • Ovarian Cysts
  • Endometriosis
  • Ovarian Cancer

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:
painful urination
history of non-vaginal candidiasis
slight afternoon/evening fatigue
poor concentration during cycle
sexual abuse during childhood
low HDL cholesterol level
frequent infections
highly elevated basophil count
history of postpartum depression
red palms/fingertips
slow reaction time
... and more than 140 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of bleeding between periods:
Cause Probability Status
Ovarian Cancer 94% Confirm
Ovarian Cysts 24% Unlikely
Endometriosis 12% Unlikely
Hypothyroidism 4% Ruled out
Adrenal Fatigue 2% Ruled out
Endometrial Hyperplasia 2% Ruled out
Low Progesterone 1% Ruled out
Endometrial Cancer 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 premenopausal or being perimenopausal, The Analyst™ will ask further questions including this one:
Do you have bleeding between periods?
Possible responses:
→ Don't know
→ No
→ Occasionally / moderately
→ Often / severely
Based on your response to this question, which may indicate either absence of bleeding between periods or bleeding between periods, 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.

Ovarian Cysts

Ovarian cysts may cause a variety of menstrual abnormalities, including Metrorrhagia, depending on the hormone produced by the cyst.  Metrorrhagia can also be a result of an ovarian cyst being unusually large, blocking the blood supply or rupturing.
