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

fatigue that worsens during the day

past amalgam filling removal

history of frequent dieting

low Metformin use

dark spots on gums

tuberculosis in family members

regular sore throats

seasonal affective disorder

back-of-neck lymph node problems

T4-only thyroid hormone use

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:

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. |
... and also rule out issues such as:
