Body odor can reveal underlying health conditions... Learn about the most prominent warning signs

 

Dr. Yelena Aleksentseva, an internist, points out that sweat itself is almost odorless, and that the smell appears when sweat secretions interact with bacteria on the skin's surface.

According to her, a change in body odor may not just be a personal hygiene issue, but could also be an indicator of underlying health problems. For example, an unusual body odor may point to liver or kidney disease.

This indicates that bacteria break down the organic components of sweat, producing volatile compounds that humans perceive as an odor. This process is particularly active in the armpits and groin areas.

She says: "The intensity of the odor is affected by the amount of sweat, the condition of the skin, the composition of the microbiome on it, genetic factors, diet, and lifestyle. For example, increased sweating creates a nutrient-rich environment for bacteria, and hair in some areas may retain moisture, which increases the intensity of the odor."

According to her, regular showering may not always solve the problem, as hormonal changes, stress, dietary habits, or the skin's microbiome composition can all contribute to altered body odor. Garlic, onions, spicy foods, and alcohol can also affect body odor because some of their components are excreted through the skin.

A persistent change in body odor without a clear cause may warrant a visit to a doctor. Certain medical conditions can cause distinctive odors; for example, diabetes may cause an acetone-like smell, kidney problems may cause an ammonia-like odor, and liver problems may lead to a rotten egg smell.

To reduce unpleasant body odor, the doctor advises maintaining good personal hygiene, choosing appropriate personal care products, and wearing breathable clothing. Deodorants primarily mask odor, while antiperspirants reduce the amount of sweat produced.

According to her, body odor is the result of a complex interaction between the skin, bacteria, diet, and overall health. If your usual body odor changes significantly and the change persists, it is advisable to consult a doctor.
