Unexplained Nausea

What Causes Unexplained Nausea?

Unexplained 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!
  • understand what's happening to your body
  • check your overall health status
  • 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 unexplained 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 "unexplained nausea" as a symptom.  Here are eight of many possibilities (more below):
  • Pancreatitis
  • Liver Congestion
  • Hepatitis
  • Congestive Heart Failure
  • Dehydration
  • Hyperparathyroidism
  • Overconsumption
  • Mesenteric Ischemia

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:
recent onset vomiting
weak appetite
sickness caused by wine
moderate abdominal pain
fatty food intolerance
recent onset nausea
meals worsen top-left abdomen pain
metallic taste in mouth
severe meal-increased pain
bags under eyes
indoor allergies
elevated B12 levels
... and more than 130 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of unexplained nausea:
Cause Probability Status
Overconsumption 92% Confirm
Hyperparathyroidism 27% Unlikely
Mesenteric Ischemia 17% Unlikely
Pancreatitis 2% Ruled out
Congestive Heart Failure 2% Ruled out
Hepatitis 1% Ruled out
Dehydration 0% Ruled out
Liver Congestion 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 unexplained nausea:
Approximately how often do you suffer from unexplained nausea? Do not include nausea that has an obvious cause, for example pregnancy, hunger or motion sickness.
Possible responses:
→ Don't know
→ Never / very rarely
→ Occasionally - a few times per year
→ Regularly - a few times per month
→ Often - several times per week
Based on your response to this question, which may indicate no unexplained nausea, occasional unexplained nausea, regular unexplained nausea or frequent unexplained nausea, The Analyst™ will consider possibilities such as:
Congestive Heart Failure

Accumulation of fluid (due to congestive heart failure) in the liver and intestines may cause nausea, abdominal pain, and decreased appetite.

Fluoride Toxicity

Nausea is an early sign of fluoride toxicity.

Hyperparathyroidism

In more severe cases there may be loss of appetite, nausea, vomiting, constipation, confusion or impaired thinking and memory, and increased thirst and urination.

Malaria

Nausea, vomiting, and diarrhea may occur.

Zinc Toxicity

Symptoms of zinc toxicity include nausea, vomiting and fever.
