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.

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):
  • Tuberculosis
  • Drug Side-Effects
  • Hypothyroidism
  • Seasonal Affective Disorder
  • Anorexia/Starvation Tendency
  • Mercury Toxicity
  • Vitamin B-Complex Need
  • Chronic Infection

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:
poorly-removed amalgams
constant fatigue
past amalgam filling removal
premenstrual bloating/weight gain
very great unexplained weight loss
dark spots on gums
constant slight bloating
regular sore throats
depression with anxiety
back-of-neck lymph node problems
fatty food craving
early puberty onset
... and more than 100 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
Hypothyroidism 95% Confirm
Tuberculosis 17% Unlikely
Anorexia/Starvation Tendency 18% Unlikely
Mercury Toxicity 5% Ruled out
Chronic Infection 5% Ruled out
Drug Side-Effects 0% Ruled out
Seasonal Affective Disorder 0% Ruled out
Vitamin B-Complex Need 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.
Vitamin B-Complex Requirement
Vitamin B-complex deficiency is known to cause feelings of internal coldness as your core body temperature dips.
