What Causes Distorted Sense Of Smell?

Distorted sense of smell can have various causes, ranging in severity from 'worrying' to '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
  • see your health summarized and in detail
  • have a doctor review your case (optional)

Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms.  In order to diagnose distorted sense of smell, 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 "distorted sense of smell" as a symptom.  Here are two possibilities:
  • Parkinson's Disease
  • Zinc Need

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:
history of deformed toenails
adult acne
zinc test metallic/fuzzy/sweet
confirmed Parkinson's disease
slow/heavy physical motion
occasional hangnails
high coffee consumption
reduced sense of smell
discontinued calcium supplementation
frequent soy consumption
darker/redder skin color
slow reaction time
... and more than 30 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of distorted sense of smell:
Cause Probability Status
Parkinson's Disease 90% Confirm
Zinc Need 60% Possible
* This is a simple example to illustrate the process
