Trembling Hands

What Causes Hand Tremors?

Hand tremors can have various causes, ranging in severity from 'troubling' to 'generally fatal'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

  • see your health summarized and in detail
  • identify any nutritional deficiencies
  • 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 hand tremors, 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 "hand tremors" as a symptom.  Here are eight of many possibilities (more below):
  • Anxiety
  • Stress
  • Multiple Sclerosis
  • Parkinson's Disease
  • Hypoglycemia
  • Dehydration
  • Mercury Toxicity
  • Hyperthyroidism

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:
very strong appetite
inability to work under pressure
insufficient water consumption
adverse reaction to delayed meals
morning sickness
having watery stools
multiple sclerosis in remission
red palms/fingertips
moving white lines across nails
high platelet count
occasional 'chills'
... and more than 190 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of hand tremors:
Cause Probability Status
Parkinson's Disease 95% Confirm
Hypoglycemia 30% Unlikely
Hyperthyroidism 24% Unlikely
Multiple Sclerosis 5% Ruled out
Stress 0% Ruled out
Dehydration 0% Ruled out
Mercury Toxicity 0% Ruled out
Anxiety 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 having muscle problems / disease, The Analyst™ will ask further questions including this one:
Do your hands tremble or have a tremor?
Possible responses:
→ No / don't know
→ Yes, but trembling stops while I am using my hands
→ Slight trembling, only when I try to use my hands
→ Obvious trembling, only when I try to use my hands
→ Constant and obvious trembling
Based on your response to this question, which may indicate either hand tremors or constant hand tremors, The Analyst™ will consider possibilities such as:
Parkinson's Disease

The main symptom of Parkinson's disease is a pronounced tremor affecting the extremities – notably the hands, chin or lips.  The tremor is most evident at rest and disappears with movement and sleep.


Early symptoms of hypoglycemia, such as hand tremors, are similar to those which occur as the result of experiencing a sudden and violent fear.

Magnesium Requirement

Early symptoms of magnesium deficiency can include fatigue, anorexia, irritability, insomnia, and muscle tremors or twitching.
