Our Translational Scientist, Dr. Nabeetha Nagalingam, was recently featured in HuffPost’s article, “‘Rotten Egg Breath’ Could Be a Sign of This Health Problem”, and Mirror’s article, “‘Rotten Egg Breath’ Could Be a Sign of Serious Health Problems – How to Combat It”, where she discussed the link between gut bacteria and bad breath.
You may have heard of sulfur, a gas known for its characteristic eggy smell. According to Dr. Nagalingam, certain gut bacteria break down sulfur-containing compounds, producing hydrogen sulfide, which causes this distinct odor.
While low levels of hydrogen sulfide in the breath are normal, high levels are often linked to inflammatory bowel diseases such as Crohn’s disease, ulcerative colitis, and irritable bowel syndrome (IBS). Additionally, bad breath could be a sign of small intestinal bacterial overgrowth (SIBO), where excess bacteria in the small intestine lead to higher hydrogen sulfide production. As Dr. Nagalingam notes, “Research shows that people with SIBO tend to have more hydrogen sulfide in their breath.”
There are several strategies to reduce sulfur-induced bad breath. One approach is incorporating probiotics containing Lactobacillus and Bifidobacteria, as these strains can lower hydrogen sulfide levels. Experimenting with your diet to identify trigger foods may also help. Before making major dietary changes or taking supplements, it’s essential to consult with a healthcare professional.

Dr. Nagalingam also highlights the role of Hydrogen Methane Breath Tests in understanding gut health. “Our ongoing research at OMED Health is paving the way for a hydrogen sulfide-specific breath test, giving patients more accurate insights into their gut function,” she explains. If you are interested in monitoring your gut health, the soon-to-be-launched OMED Health Breath Analyzer and App aims to help you learn more about what triggers your digestive discomfort. The device will help users track breath samples and lifestyle factors, empowering them to make more informed decisions about their digestive health.
