Doctors note that changes in body odor can sometimes reflect underlying health issues. According to medical observations discussed by Russian specialists and reported by Sib.fm, certain illnesses may influence the way sweat or breath smells due to biochemical processes in the body. These signs are not diagnostic on their own, but they may serve as signals to seek medical advice.
Dermatologist Irana Skorogudayeva explains that in medicine there is a theory suggesting that even serious diseases can be associated with characteristic odor changes. When the body is affected by certain conditions, metabolic byproducts and bacterial activity may alter natural scent patterns.
Possible Odor Changes and Their Associations
Strong ammonia-like odor
This type of smell may be associated with kidney or liver dysfunction, as well as urinary tract infections. It can occur when the body has difficulty eliminating nitrogen-containing waste products.
Sweet or acetone-like odor
A scent similar to overripe fruit or acetone is sometimes linked to diabetes. This occurs when the body begins breaking down fats instead of glucose, producing ketones.
Persistent unpleasant breath odor
While often related to oral hygiene, ongoing bad breath may also be connected to conditions affecting the throat, lungs, or digestive system, including stomach disorders.
Unusually heavy or decaying odor
In some respiratory infections, such as severe lung conditions, metabolic changes and bacterial activity may contribute to a noticeably altered smell.
Fish-like odor
This type of odor may be associated with certain bacterial infections, particularly in the genital area, and usually requires medical evaluation.
Important Clarification
Health professionals emphasize that body odor alone cannot confirm any disease, including cancer or other serious conditions. Many factors—such as diet, stress, medication, hygiene habits, and environment—can influence scent. However, persistent or sudden changes, especially when accompanied by other symptoms, should be discussed with a qualified healthcare provider.
Early attention to unusual signs can support timely evaluation and peace of mind.
