Warm/Cold Hands And Feet

What Causes Warm Or Cold Extremities?

Warm or cold extremities can have various causes, ranging in severity from 'very minor' to 'very serious'.  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 warm or cold extremities, 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 "warm or cold extremities" as a symptom.  Here are eight possibilities:
  • Raynaud's Phenomenon
  • Hypothyroidism
  • Low Progesterone
  • Adrenal Fatigue
  • Stress
  • Mercury Toxicity
  • Chronic Fatigue-Fibromyalgia
  • Poor Circulation

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:
yellow/yellowish fingernails
recurring depression
history of sinusitis
afternoon headaches
moderate mercury toxicity
depression with fatigue
being an unsocial person
having amalgam fillings
low diastolic blood pressure
weak appetite
poor concentration during cycle
non-human estrogen use
... and more than 210 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of warm or cold extremities:
Cause Probability Status
Poor Circulation 97% Confirm
Hypothyroidism 24% Unlikely
Stress 21% Unlikely
Mercury Toxicity 2% Ruled out
Chronic Fatigue-Fibromyalgia 2% Ruled out
Low Progesterone 2% Ruled out
Adrenal Fatigue 0% Ruled out
Raynaud's Phenomenon 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.

In the Metabolic Symptoms section of the questionnaire, The Analyst™ will ask the following question about warm/cold hands and feet:
How warm or cold do your hands and feet tend to be? Consider when you shake hands with other people: do their hands usually feel warm (meaning your hands are colder) or cold (your hands are warmer)?
Possible responses:
→ Usually or always cold
→ Colder than average
→ Average / don't know
→ Warmer than average
→ Usually or always warm
Based on your response to this question, which may indicate either cold hands and/or feet or warm hands and/or feet, The Analyst™ will consider possibilities such as:
Chronic Fatigue / Fibromyalgia Syndrome

Raynaud's phenomenon (severe cold hands and feet) affects about 16% of fibromyalgia sufferers.

Poor Circulation

In cases of peripheral vascular disease, the arteries narrow and there is a marked reduction of blood flow especially to the fingers and toes.

Progesterone Low or Estrogen Dominance

Cold hands and feet, often caused by low thyroid function, may be a symptom of estrogen excess or low progesterone influencing thyroid function.
