What is Underarm Odor?

This is a problem that needs no defining. It is the foul, offensive smell that is emitted from the armpit. It is a frustrating condition that affects many people around the world.

What Causes Underarm Odor?

Know about some of the main causes of Underarm Odor.

Accumulation of sweat

The problem mostly occurs due to accumulation of sweat in the armpits. However, sweat alone is not responsible for the foul odor. This is due to the fact that sweat itself has little or no detectable odor. The offensive smell is actually the result of bacterium that thrives in bodies that do not get enough oxygen. The odor is emitted when bacteria get mixed with sweat. When sweat is released through the armpits, it gets decomposed (broken down) and is then consumed by bacteria that are present in the underarm area. It is these bacteria which emit a foul-smelling chemical.

Food items

Certain food items contain a small amount of toxins that can get into the system during consumption. Naturally, the human body releases them through sweat as waste products. Consumption of these foods leads to a build-up of toxins within the body. The presence of these toxins is the reason behind foul armpit odor. Foods such as garlic and onions, spicy items, fast foods and beverages like coffee and alcohol may also give rise to armpit odor.


Some other reasons that can cause excessive sweating and subsequently, foul underarm odor are liver disease, menopause, low blood sugar, emotional stress, metabolic dysfunction, etc. It has also been observed that sweating can be the symptoms of some serious health problems like fungal infections, kidney disease, liver disease, etc.

How to Eliminate Underarm Odor?
