However, when bacteria are present, they break down the acids contained in the sweat produced by the apocrine glands and produce a sour smell similar to vinegar in the armpits, breasts and genital-anal area. If your sweat smells like ammonia, review your diet. Body odor is what you smell when sweat comes in contact with bacteria on your skin. Sweat itself doesn't smell, but when skin bacteria mix with sweat, they produce an odor.
Body odor may smell sweet, sour, spicy, or onion. The amount you sweat doesn't necessarily affect body odor. This is why a person may have an unpleasant body odor but not sweat. On the contrary, a person may sweat excessively but not smell.
That's because body odor is the result of the type of bacteria in the skin and the way that bacteria interact with sweat, not the sweat itself. This could mean that you don't wash often enough, thoroughly, or that you don't use enough soap when you get foam. Sometimes body odor isn't to blame if you smell a sour scent. Rather, it could be your nose.
According to Langone Health at New York University, a foreign object trapped in the nose can affect the sense of smell, as can infection with certain viruses, including the virus that causes COVID-19.In some cases, the pungent smell of vinegar in sweat may be due to an underlying health condition, such as diabetes or kidney disease. Please, I need your help because my armpit smells really bad, no matter how I showered and the types of deodorants I used. In the past six months I noticed that my armpits smell really bad, but a few months later I noticed that my stools smell exactly the same. It makes me feel very uncomfortable with people because I automatically think they can smell me and they think I'm not hygienic when I actually shower and have sprayed deodorant on myself.
