Reduced Muscle Tone

What Causes Loose Muscles?

Loose muscles can have various causes, ranging in severity from 'worrying' to 'very serious'.  Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.

Diagnose your symptoms now!
  • understand what's happening to your body
  • learn what you should be doing right now
  • identify any nutritional deficiencies

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose loose muscles, 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 "loose muscles" as a symptom.  Here are four possibilities:
  • Neuritis/Neuropathy
  • Myasthenia Gravis
  • Nephrotic Syndrome
  • Premature Aging

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:
brittle fingernails
paralysis not due to physical injury
frequent odd skin sensations
cold weather muscle weakness
edema of the knees
long focal length
loss of appetite
regular infections
edema of the eyelids
significant abdominal pain
low lymphocyte count
reduced sense of smell
... and more than 20 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of loose muscles:
Cause Probability Status
Nephrotic Syndrome 97% Confirm
Myasthenia Gravis 26% Unlikely
Neuritis/Neuropathy 4% Ruled out
Premature Aging 4% 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 Muscular Symptoms section of the questionnaire, The Analyst™ will ask the following question about reduced muscle tone:
Has your muscle tone been declining? Low tone muscles are soft, loose and allow great range of motion; high tone muscles are tight, rigid and allow less motion at the joints.
Possible responses:
→ Don't know / I have always had soft/loose muscles
→ No, my muscles are still normal or high tone
→ Yes, my muscles are now a little softer and looser
→ Yes, my muscles are now very soft and loose
Based on your response to this question, which may indicate no loss of muscle tone, some loss of muscle tone or great loss of muscle tone, The Analyst™ will consider possibilities such as:
Nephrotic Syndrome

Over time, the loss of protein due to nephrotic syndrome causes muscles to become weak and small (muscle wasting).

Neuritis/Neuropathy

Loss of muscle tone is a common neuritis symptom: The affected nerve keeps the muscles from staying toned.
