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):
  • Fluorosis
  • Chronic Renal Insufficiency
  • Intestinal Obstruction
  • Diabetes II
  • Food Allergies
  • Gallbladder Disease
  • Zinc Toxicity
  • Aspartame/Neotame Side-Effects

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 colds/flus
gradual decline in speaking ability
refined white flour consumption
mild right hypochondriac discomfort
having a high fever
partial aspartame/neotame avoidance
numb/burning/tingling extremities
microcytic red cells
spacey/unreal feelings
chronic vomiting
epigastric pressure after meals
sugar-free soft drink consumption
... and more than 150 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
Food Allergies 98% Confirm
Chronic Renal Insufficiency 29% Unlikely
Intestinal Obstruction 27% Unlikely
Fluorosis 2% Ruled out
Diabetes II 2% Ruled out
Gallbladder Disease 0% Ruled out
Aspartame/Neotame Side-Effects 0% Ruled out
Zinc Toxicity 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:
Delayed Gastric Emptying (Gastroparesis)

Approximately 50% of patients with chronic idiopathic nausea and vomiting evaluated in referral centers have gastroparesis.  A viral etiology was suggested in these patients and in other series when there was an acute onset of nausea and vomiting with other features of a viral illness (fever, myalgia, diarrhea, fatigue, or abdominal cramping).

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.
