Duration Of Current Nausea Episodes

What Causes Chronic Nausea?

Chronic nausea 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.

Diagnose your symptoms now!
  • check your overall health status
  • have a doctor review your case (optional)
  • 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 chronic nausea, 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 "chronic nausea" as a symptom.  Here are eight of many possibilities (more below):
  • Gastritis
  • Enlarged Spleen
  • Hepatitis
  • Zinc Toxicity
  • West Nile Virus
  • Magnesium Toxicity
  • Cirrhosis Of The Liver
  • Congestive Heart Failure

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:
frequent unexplained nausea
recent loss of appetite
meal-induced pain for 1-4 weeks
very pale fingernails
severe epigastric pain
reduced mental clarity
hepatitis A
blue/bluish fingernails
history of copper supplementation
being medication sensitive
recent transplant surgery
highly elevated eosinophil count
... and more than 70 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of chronic nausea:
Cause Probability Status
Hepatitis 96% Confirm
Gastritis 28% Unlikely
Enlarged Spleen 26% Unlikely
Zinc Toxicity 1% Ruled out
Magnesium Toxicity 0% Ruled out
Cirrhosis Of The Liver 0% Ruled out
Congestive Heart Failure 0% Ruled out
West Nile Virus 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 Gastrointestinal Symptoms section of the questionnaire, The Analyst™ will ask the following question about duration of current nausea episodes:
If you suffer significantly from unexplained nausea (at least once per week), for how long has this been a problem?
Possible responses:
→ It is not a problem / don't know
→ It started within the last week
→ It started within the last month
→ I've had it for 1 to 3 months
→ I've had it for over 3 months
Based on your response to this question, which may indicate no significant nausea, recent onset nausea, nausea for 1-3 months or chronic nausea, The Analyst™ will consider possibilities such as:
Pancreatitis

Most cases of acute pancreatitis resolve within a week; chronic pancreatitis does not resolve itself and results in a slow destruction of the pancreas.
