Introduction:

Foot odor is a common medical condition. It happens when sweat builds up, resulting in the growth of bacteria on the skin. The smell, however, is not due to the sweat, but it is due to the byproduct of bacteria on the feet. These bacteria contribute to bad odors. Smelly feet are otherwise known as Bromodosis. Even though it is uncomfortable, it is a treatable condition. There are multiple self-care methods like maintaining foot hygiene that helps in keeping the foot dry and eliminate foot odor.

What Are the Common Causes and Risk Factors of Smelly Feet?

Bacteria are to be blamed. The bacteria like dark, damp, sweaty places and they multiply in sweat. So bacteria will feast on the feet because feet have more sweat glands than other parts of the body. Sweat creates a prime environment for the bacteria to grow, multiply and their metabolic processes emit a bad odor. And these bacteria can also feed on the dead skin cells and oils present in the skin and start to grow into colonies. They get rid of the wastes that are breaking down from the oils and dead skin cells in the form of organic acids. These organic acids produce a bad odor.
