Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "foul-smelling flatulence" as a symptom. Here are four possibilities:
- Carbohydrate Intolerance
- Lactose Intolerance
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:

In the Gastrointestinal Symptoms
section of the questionnaire, The Analyst™
will ask the following question about foul-smelling gas:
When you pass gas ("fart"), how does it usually smell?
→ Don't know / it varies a lot / don't want to know!
→ Usually odorless
→ Usually about 'normal' / 'noticeable'
→ It varies between 'normal' and terrible
→ Usually terrible / people run away screaming
Based on your response to this question, which may indicate odorless flatulence, 'normal'-smelling flatulence, foul-smelling flatulence or very foul-smelling flatulence, The Analyst™
will consider possibilities such as:
Infections of the digestive tract can lead to foul-smelling flatulence. There are many different bacteria and viruses that can cause infections in the lining of the digestive tract. Some of these may be associated with traveling to different parts of the world; infections are usually accompanied by gas, diarrhea, fever, and abdominal pain.
Lactose is the sugar found in dairy products. When we don't have enough of the enzyme necessary to break down lactose, it remains in our digestive tract for odor-causing bacteria to feed on.
