Flatulence

What Causes Flatulence?

Flatulence 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!
  • see your health summarized and in detail
  • learn what you should be doing right now
  • 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 flatulence, 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 "flatulence" as a symptom.  Here are eight of many possibilities (more below):
  • Mesenteric Ischemia
  • Atrophic Gastritis
  • Giardia
  • Colon Cancer
  • Small Intestine Cancer
  • Stomach Acid Deficiency
  • Ulcerative Colitis
  • 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:
frequent rotten egg burps
severe right iliac pain
minor joint pain/swelling/stiffness
chronic diarrhea
having loose stools
history of colon cancer
moderate unexplained weight loss
frequent stools
frequent episodes of diarrhea
meal-related bloating
abdominal pain reduced by eating
significant abdominal 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 flatulence:
Cause Probability Status
Atrophic Gastritis 90% Confirm
Gastroenteritis 23% Unlikely
Small Intestine Cancer 23% Unlikely
Ulcerative Colitis 1% Ruled out
Giardia 0% Ruled out
Colon Cancer 0% Ruled out
Stomach Acid Deficiency 0% Ruled out
Mesenteric Ischemia 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 flatulence:
Do you suffer from excess lower bowel gas (flatulence)? The average adult passes gas ("farts") 8 to 20 times a day, but this depends on various factors. Try to compare yourself to others with similar diet and eating habits.
Possible responses:
→ No / average / only after overeating / don't know
→ Yes, but it is probably due to my diet
→ Somewhat more than most people
→ Very much more than most people
Based on your response to this question, which may indicate flatulence, excessive flatulence or severe flatulence, The Analyst™ will consider possibilities such as:
Gallbladder Disease

Persistent and severe flatulence may be a symptom of gallbladder problems.

IBS (Irritable Bowel Syndrome)

The altered digestion found in IBS will usually lead to higher gas production.  If intestinal transit is too quick, food is only partially digested.  Natural bacteria residing in the gut will cause fermentation of this food, producing gas.  Fast-moving bowel contents may also lead to pockets of trapped gas, worsening the problem.  Some studies suggest that the populations of gut bacteria in IBS patients differ from the normal, with more 'bad' than 'good' bacteria, which can cause excess flatulence.
