Feeling Cold For No Reason

What Causes Feeling Cold?

Feeling cold can have various causes, ranging in severity from 'worrying' to 'life-threatening'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • learn what you should be doing right now
  • identify any nutritional deficiencies
  • 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 feeling cold, 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 "feeling cold" as a symptom.  Here are eight of many possibilities (more below):
  • Anorexia/Starvation Tendency
  • Underconsumption
  • Panic Attacks
  • Seasonal Affective Disorder
  • Chronic Infection
  • Drug Side-Effects
  • Guillain-Barre Syndrome
  • 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:
hair loss on lower legs
low systolic blood pressure
poor tolerance of heat
consuming too few calories
sugar/sweet craving
incoherent speech
history of adolescent acne
recent onset diarrhea
hypoglycemia
poor cold weather tolerance
very brittle hair
inability to tell hot from cold
... and more than 90 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of feeling cold:
Cause Probability Status
Guillain-Barre Syndrome 99% Confirm
Underconsumption 30% Unlikely
Adrenal Fatigue 18% Unlikely
Anorexia/Starvation Tendency 2% Ruled out
Seasonal Affective Disorder 0% Ruled out
Chronic Infection 0% Ruled out
Drug Side-Effects 0% Ruled out
Panic Attacks 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 feeling cold for no reason:
How often do you feel cold for no apparent reason? This question refers to your whole body, not just hands and feet.
Possible responses:
→ Don't know / hands and feet only
→ Never / less than once a year
→ Occasionally - several times a year
→ Regularly - several times a month
→ Often/always
Based on your response to this question, which may indicate not feeling unusually cold, occasionally feeling unusually cold, regularly feeling unusually cold or often/always feeling unusually cold, The Analyst™ will consider possibilities such as:
(Prescription) Drug Side-Effects

Certain medications – such as those prescribed for hypertension, angina, or migraine – can cause feelings of being cold because beta blockers may reduce the circulation in the extremities while increasing blood circulation to the heart.

Anorexia / Starvation Tendency

Underweight people often feel cold due to having less fat and muscle mass.  Body fat acts as insulation to keep the body warm; muscle activity generates heat.

Diabetes Type II

The coldness caused by diabetic hypoglycemia is usually accompanied by weakness and, in severe cases, disorientation and fainting.

Underconsumption

As a result of fasting, skipping meals or eating too little, the body will try to conserve energy by producing less body heat, thus reducing your body temperature.

Vitamin B-Complex Requirement

Vitamin B-complex deficiency is known to cause feelings of internal coldness as your core body temperature dips.
