Duration Of Current Vomiting Episodes

What Causes Chronic Vomiting?

Chronic vomiting 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.

  • understand what's happening to your body
  • 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 vomiting, 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 vomiting" as a symptom.  Here are eight of many possibilities (more below):
  • Malaria
  • Gastritis
  • Appendicitis
  • Chronic Renal Insufficiency
  • Ovarian Cysts
  • Cyclic Vomiting Syndrome
  • Aspartame/Neotame Side-Effects
  • Gastroenteritis

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:
occasional unexplained nausea
severe left iliac pain
severe flatulence
foul-smelling flatulence
significant abdominal pain
recent onset abdominal pain
acute abdominal pain
frequent unexplained nausea
kidney failure
significant right iliac pain
... and more than 60 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 vomiting:
Cause Probability Status
Malaria 98% Confirm
Aspartame/Neotame Side-Effects 21% Unlikely
Chronic Renal Insufficiency 16% Unlikely
Ovarian Cysts 3% Ruled out
Cyclic Vomiting Syndrome 1% Ruled out
Gastritis 0% Ruled out
Gastroenteritis 0% Ruled out
Appendicitis 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 vomiting episodes:
If you suffer significantly from unexplained vomiting (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 vomiting, recent onset vomiting, vomiting for 1-3 months or chronic vomiting, The Analyst™ will consider possibilities such as:
