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

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:
vomiting for 1-3 months
history of chronic thyroiditis
hot flashes during period
history of adult acne
processed meat consumption
having hard stools
moderate afternoon/evening fatigue
poor cold weather tolerance
yellow/yellowish fingernails
occasional odd skin sensations
incoherent speech
seizures
... 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 irregular menstrual cycles:
Cause Probability Status
Diabetes II 92% Confirm
Hypothyroidism 24% Unlikely
Ovarian Cysts 20% Unlikely
Polycystic Ovary Syndrome 5% Ruled out
Adrenal Fatigue 0% Ruled out
Aspartame/Neotame Side-Effects 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.

Ovarian Cysts

In some cases ovarian cysts can cause problems with menstrual periods such as abnormal or irregular bleeding, especially in women with endometriosis.
