Chapped Lips

What Causes Chapped Lips?

Chapped lips can have various causes, just like most other symptoms.  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 chapped lips, 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 "chapped lips" as a symptom.  For example, vitamin A toxicity.

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:
severe emotional instability
major joint pain/swelling/stiffness
... and so on

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of chapped lips.

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 Mouth/Oral Symptoms section of the questionnaire, The Analyst™ will ask the following question about chapped lips:
Do you suffer from chapped lips?
Possible responses:
→ No / don't know
→ Occasionally / moderately
→ Often / severely
Based on your response to this question, which may indicate chapped lips, The Analyst™ will consider possibilities such as Vitamin A Toxicity.  Chapped lips and dry skin, which may be early symptoms, will generally occur in the majority of patients, particularly in dry weather.
