Irregular Menstrual Cycles

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.

Diagnose your symptoms now!
  • understand what's happening to your body
  • check your overall health status
  • learn what you should be doing right now

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
  • Hypothyroidism
  • Polycystic Ovary Syndrome
  • Aspartame/Neotame Side-Effects
  • Ovarian Cysts
  • Perimenopause
  • Adrenal Fatigue

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:
constant thirst
2hr postprandial glucose 160-200mg%
red palms/fingertips
slight bitter taste in mouth
moderate unexplained weight gain
regularly feeling unusually cold
somewhat disturbed sleep
very great unexplained weight gain
hyperthyroidism in family members
low free T4
difficulty losing weight
... 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
Aspartame/Neotame Side-Effects 91% Confirm
Hypothyroidism 30% Unlikely
Adrenal Fatigue 20% Unlikely
Perimenopause 1% Ruled out
Polycystic Ovary Syndrome 1% Ruled out
Diabetes II 0% Ruled out
Ovarian Cysts 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.
