As a specialist in dermatology with a focus on skin health and hygiene, I can provide a detailed explanation on the causes of smelly armpits, which is a common concern for many individuals.
Step 1: English Answer
Body odor, particularly in the armpit region, is a complex phenomenon that involves multiple factors. The primary cause of smelly armpits is the interaction between sweat and the bacteria that naturally reside on our skin. Here's a more in-depth look at the process:
1. Sweat Production: Our body has two main types of sweat glands - eccrine and apocrine glands. Eccrine glands are found all over the body and produce a watery sweat that helps regulate body temperature. Apocrine glands, on the other hand, are primarily located in the armpits and genital areas and produce a thicker, milky sweat that is rich in proteins and lipids.
2. Bacterial Activity: The skin is home to a diverse community of bacteria. When the sweat produced by the apocrine glands reaches the surface of the skin, it provides a fertile ground for these bacteria to thrive. The bacteria, particularly those that are anaerobic (they do not require oxygen to survive), break down the proteins and lipids in the sweat.
3. Odor Production: The breakdown of sweat by bacteria results in the production of various compounds, including ammonia, acids, and other volatile sulfur compounds. These compounds are responsible for the characteristic smell associated with body odor.
4. Factors Influencing Bacterial Growth: Several factors can influence the growth of bacteria and, consequently, the intensity of body odor. These include:
- Diet: Certain foods, such as garlic, onions, and spices, can affect the smell of sweat as they contain sulfur compounds that can be metabolized and excreted through sweat.
- Hormonal Changes: Hormonal fluctuations, particularly during puberty, menstruation, and pregnancy, can affect sweat production and the composition of apocrine sweat, leading to stronger body odor.
- Stress: Stress can increase sweat production, which in turn can lead to a more noticeable body odor.
- Physical Activity: Engaging in physical activities that increase body temperature and cause sweating can exacerbate body odor.
- Clothing: Wearing tight or non-breathable clothing can create a moist environment that promotes bacterial growth.
5. Genetics: Some individuals may be genetically predisposed to produce more apocrine sweat or have a higher concentration of odor-causing compounds in their sweat.
6. Heredity and Ethnicity: There is evidence to suggest that certain populations may have a higher prevalence of apocrine gland activity, which can influence body odor.
7.
Hygiene Practices: Poor hygiene can lead to the accumulation of sweat, bacteria, and dead skin cells, which can intensify body odor. Regular washing with antibacterial soap and maintaining clean clothing can help control odor.
8.
Medical Conditions: Certain medical conditions, such as hyperhidrosis (excessive sweating) or bromhidrosis (foul body odor), can contribute to smelly armpits.
In conclusion, the cause of smelly armpits is multifaceted, involving a combination of sweat production, bacterial activity, and various influencing factors. Maintaining good personal hygiene, managing stress, and making dietary adjustments can help in managing and reducing body odor.

Body odor is caused by bacteria breaking down sweat and is largely linked to the apocrine glands. ... They are scent glands. The apocrine glands are mainly responsible for body odor because the sweat they produce is high in protein, which bacteria can break down easily.Nov 29, 2017
