Causes of Smelly Feet

1. Excessive feet sweating 

What causes foot odor?We already know that foot odor is a result of perspiration and bacterial environment on our skin. The more we sweat, the more we tend to experience foot odor. We have about half a million sweat glands on our feet, and every foot produces about half a liter of sweat per day. The most sweat is produced by the front part of the feet. 

The amount of these glands actually depends on how big the feet are. A young girl with small feet has logically fewer sweat glands than a two meters tall basketball player. Another fact is that an amount of sweat per glands varies from person to person. Genetics, age, sex, and health condition affect how much we do sweat.

People with increased perspiration level on their feet, also known as plantar hyperhidrosis, usually experience foot odor. Besides foot odor, abnormal feet sweating can lead to other complications, such as fungus or skin irritations. If you want to get rid of foot odor and you know that your feet sweat profusely, the first step should be to prevent this sweating. Later we are going to say how to do it.

Skin bacteria are a natural part of human flora. These diverse communities of bacteria, also called skin microbiota, are harmless and even beneficial in the fight against microbes. According to one study, skin bacteria help immune cells to get rid of harmful microorganism. But they also play the main role in body odor.

Brevibacteria is considered the main culprit of smelling feet. While ingesting dead skin from feet, amino acid methionine is converted into methanethiol, which is a very unpleasant smelling gas. Propionibacteria and Staphylococcus epidermis are another trigger of foot odor.

3. Fungus

Athlete’s foot, also called tinea pedis, is another condition that can cause smelly feet. It is a fungal infection that can be transferred by direct contact with other person or by touching contaminated surfaces such as showers, dressing rooms, or a floor around swimming pools. Treating of this infection will also reduce foot odor.

In general, it is tricky to say which medicaments affect excessive sweating because everybody metabolizes medicines differently due to genetics and health condition. But there are some groups of medicaments that are related to profuse perspiration such as antidepressant, anti-inflammatory drugs, and pain killers.
