Bleeding Between Periods

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.

Diagnose your symptoms now!
  • check your overall health status
  • understand what's happening to your body
  • have a doctor review your case (optional)

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 possibilities (more below):
  • Ovarian Cancer
  • Low Progesterone
  • Adrenal Fatigue
  • Hypothyroidism
  • Ovarian Cysts
  • Fibroids
  • Endometrial Hyperplasia
  • 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:
regular postprandial somnolence
low diastolic blood pressure
hyperactivity
intermittent abdominal fullness
regular unexplained nausea
dizziness when standing up
pear-shaped body when overweight
often/always feeling unusually cold
premenstrual weight gain
low T3 free level
non-vaginal candidiasis
painful deep penetration during sex
... 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 Cysts 90% Confirm
Endometriosis 24% Unlikely
Adrenal Fatigue 20% Unlikely
Endometrial Hyperplasia 3% Ruled out
Hypothyroidism 1% Ruled out
Fibroids 0% Ruled out
Low Progesterone 0% Ruled out
Ovarian Cancer 0% Ruled out
* This is a simple example to illustrate the process
