Differential Diagnosis for Egg Smelling Burps

The symptom of egg smelling burps, also known as halitosis or more specifically, hydrogen sulfide burps, can be caused by various conditions. Here's a breakdown of potential diagnoses:

  • Single Most Likely Diagnosis

    • Gastroesophageal Reflux Disease (GERD): This condition is characterized by stomach acid frequently flowing back into the tube connecting the mouth and stomach (esophagus). The acid can cause symptoms such as burping, which may have a sour or egg-like smell due to the presence of hydrogen sulfide gas produced during digestion.

  • Other Likely Diagnoses

    • Helicobacter pylori (H. pylori) Infection: This bacterial infection can lead to stomach ulcers and is known to produce volatile sulfur compounds, which can cause bad breath and burps with a characteristic egg smell.
    • Lactose Intolerance or Other Food Intolerances: Difficulty digesting certain foods can lead to gas production in the stomach and intestines, resulting in burps that may smell like eggs.
    • Irritable Bowel Syndrome (IBS): Although primarily known for causing abdominal pain and changes in bowel movements, some individuals with IBS may experience gas and burping, potentially with an unpleasant odor.

  • Do Not Miss Diagnoses

    • Gastric Cancer: Although rare, gastric cancer can cause a variety of symptoms including weight loss, abdominal pain, and changes in digestion. Bad breath or unusual smelling burps could be an early sign in some cases.
    • Liver Disease: Certain liver conditions can lead to an increase in sulfur-containing compounds in the body, potentially causing halitosis or foul-smelling burps.

  • Rare Diagnoses

    • Trimethylaminuria: A rare genetic disorder that affects the body's ability to break down trimethylamine, a compound found in certain foods. This can lead to a strong, fishy or egg-like body odor and bad breath.
    • Small Intestine Bacterial Overgrowth (SIBO): An excessive growth of bacteria in the small intestine can lead to malabsorption and production of gas, potentially causing burps with an unpleasant smell.
