What Causes Irregular Menstrual Cycles?

Irregular menstrual cycles can have various causes, ranging in severity from 'very minor' to 'life-threatening'.  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 irregular menstrual cycles, 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 "irregular menstrual cycles" as a symptom.  Here are seven possibilities:
  • Diabetes II
  • Polycystic Ovary Syndrome
  • Perimenopause
  • Ovarian Cysts
  • Aspartame/Neotame Side-Effects
  • Adrenal Fatigue
  • Hypothyroidism

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:
slight abdominal fullness
history of postpartum depression
occasional confusion/disorientation
high sensitivity to bright light
frequent odd skin sensations
vision disturbances
low T3 free level
hypothyroidism in family members
history of sinusitis
yellow/yellowish fingernails
adrenal insufficiency
short-term memory failure
... and more than 150 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of irregular menstrual cycles:
Cause Probability Status
Adrenal Fatigue 95% Confirm
Aspartame/Neotame Side-Effects 24% Unlikely
Diabetes II 16% Unlikely
Polycystic Ovary Syndrome 2% Ruled out
Hypothyroidism 2% Ruled out
Ovarian Cysts 0% Ruled out
Perimenopause 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:
Are your natural menstrual cycles irregular? In other words, does the cycle length and/or the amount/duration of bleeding vary significantly from cycle to cycle? Do not answer if you have been using hormonal birth control for over 6 months.
Possible responses:
→ Don't know / used birth control for over 6 months
→ No, my cycles are usually quite similar/regular
→ Yes, I have occasional moderate cycle variations
→ Yes, regular moderate variation / occasional major
→ Yes, regular major variations, very unpredictable
Based on your response to this question, which may indicate slightly irregular menstrual cycles, irregular menstrual cycles or very irregular menstrual cycles, The Analyst™ will consider possibilities such as:
Diabetes Type II

Women with long or very irregular menstrual cycles may be at increased risk of developing type 2 diabetes mellitus.
