Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose rotten egg burps, 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 "rotten egg burps" as a symptom. Here are eight of many possibilities (more below):

Food Allergies
Giardia
Heartburn
Overconsumption
Gluten Sensitivity
Stress
Helicobacter Pylori Infection
Bacterial Dysbiosis

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:

pain/burning behind breastbone

sugar/sweet craving

gastritis

reduced mental clarity

high platelet count

physical abuse during childhood

regular sleepwalking

frequent episodes of diarrhea

severe facial burning/tingling

sexual abuse during childhood

PPI antacid use

infrequent meal-induced pain

... and more than 140 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of rotten egg burps:

Cause	Probability	Status
Heartburn	99%	Confirm
Food Allergies	19%	Unlikely
Bacterial Dysbiosis	14%	Unlikely
Giardia	3%	Ruled out
Overconsumption	1%	Ruled out
Gluten Sensitivity	1%	Ruled out
Stress	1%	Ruled out
Helicobacter Pylori Infection	1%	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.

If you indicate occasional problems caused by eating, regular problems caused by eating or frequent problems caused by eating, The Analyst™ will ask further questions including this one:

Do you ever suffer from very foul burps that can best be described as having a 'rotten egg' or 'sulfur' smell/taste?

Possible responses:

→ No / rarely / don't know
→ Yes, but only if I eat too much
→ Yes, a few times a year even if I don't overeat
→ Yes, a few times a month even if I don't overeat
→ Yes, frequently even if I don't overeat

Based on your response to this question, which may indicate rotten egg burps after overeating, occasional rotten egg burps, rotten egg burps or frequent rotten egg burps, The Analyst™ will consider possibilities such as:

Allergy to Foods (Hidden)

Bacterial Dysbiosis

Delayed Gastric Emptying (Gastroparesis)

Gallbladder Disease

If you suffer from sulfur burps and gas you may have a problem in the gallbladder or small intestine. Rotten egg burps are caused by hydrogen sulfide gas which is produced by gut bacteria when certain types of food pass through the digestive system. When gallstones block the bile duct and prevent bile from helping to digest fatty foods, gas may be produced due to incomplete digestion.

Giardiasis Infection

Recurrent "rotten-egg" burps accompanied by diarrhea could be a sign of Giardia lamblia infection.

Gluten Sensitivity / Celiac Disease

Heartburn / GERD / Acid Reflux

Helicobacter Pylori Infection

Overconsumption

Stress
