If you battle body odor, the answer may be in your gut. A study published in the European Journal of Gastroenterology and Hepatology found that the same bacteria that can lead to stomach ulcers can also cause certain types of body odor.
Helicobacter pylori is found in the stomachs of about 50% of the population in the Western world. Out of these 50%, 80% show no symptoms. This bacteria seeks out a neutral place to thrive away from stomach acid and it adheres to the stomach's internal wall. When an overgrowth of this bacteria occurs, it causes gastritis and ulcers. It can also infect the intestinal tract, leading to IBS.
So, now, what does this have to do with body odor?
When H pylori thrives in the stomach, it produces high amounts of an enzyme called urease, which breaks down urea (which exists naturally in the stomach). Urea then breaks down in to carbon dioxide and ammonia, which then is released in to the bloodstream, and then released through sweat. Most people have ammonia in their sweat, however people infected with H pylori will have higher amounts of it.
So, if you're one of those people that has a hard time with pungent odors, or experience odor shortly after cleansing, it may be ammonia in your sweat caused by H pylori in your stomach.
If you suspect that you have H pylori and have symptoms of ulcers or other gastric symptoms, visit your doctor for a complete diagnosis and treatment options. Probiotics have been found to help ease the symptoms and control the growth of H pylori, so you may look at this as an option with your doctor.
(High levels of ammonia in sweat can also be caused by the body's inability to fully break down protein, a condition called proteinuria. Low-carb, high protein diets can also be the cause, as consuming more protein than the body can metabolize can also lead to elevated serum levels of ammonia, and thus in sweat. If you suspect that you have proteinurea, it is a serious condition; please seek medical attention.)
