General Weakness

What Causes Feeling Weak?

Feeling weak can have various causes, ranging in severity from 'minor' to 'generally fatal'.  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 weak, 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 weak" as a symptom.  Here are eight of many possibilities (more below):
  • Dehydration
  • Low Carbohydrate Diet Consequences
  • Excess Water Consumption
  • Electrical Hypersensitivity
  • Hepatitis
  • Aspartame/Neotame Side-Effects
  • Stress
  • Hyperparathyroidism

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:
being fatigued
poor mental clarity
facial flushing
jumpiness
shortness of breath when at rest
occasional confusion/disorientation
high low-calorie soda consumption
severe emotional instability
craving for salt
sugar/sweet craving
recent onset nausea
mild right lumbar discomfort
... and more than 120 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 weak:
Cause Probability Status
Excess Water Consumption 98% Confirm
Hyperparathyroidism 20% Unlikely
Low Carbohydrate Diet Consequences 15% Unlikely
Stress 0% Ruled out
Dehydration 0% Ruled out
Electrical Hypersensitivity 0% Ruled out
Aspartame/Neotame Side-Effects 0% Ruled out
Hepatitis 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 General Symptoms section of the questionnaire, The Analyst™ will ask the following question about general weakness:
Do you have a sensation of general weakness?
Possible responses:
→ No / don't know
→ Occasional slight weakness but usually I'm fine
→ Frequent slight / occasional moderate weakness
→ Frequent moderate / occasional severe weakness
→ Severe weakness (almost) always, I can't function
Based on your response to this question, which may indicate general weakness, The Analyst™ will consider possibilities such as:
Andropause/Male Menopause

The sensation of weakness, especially muscle weakness, may be due to the loss of muscle mass seen in andropause.

Dehydration

A loss of 4-5% of body weight of fluid decreases the capacity for hard muscular work by 20-30%.

Effects of a Low Carbohydrate Diet

Gradually increasing weakness is a sign of ketosis.  The May 2004 Annals of Internal Medicine study showed that most of the Atkins Dieters suffered significantly more general weakness.
