Body Odor

The main symptom is a noticeable and often offensive odor, but other symptoms may vary depending on the cause and factors involved. Here are the common symptoms and characteristics associated with body odor:

• Unpleasant smell: The most prominent symptom is the presence of a foul or unpleasant odor, often described as pungent, musky, or rotten.
• Exacerbation with sweating: One of the key factors that intensifies body odor is sweating. When a person sweats, it creates a moist environment that allows bacteria on the skin's surface to break down sweat and produce odor. Understanding this relationship can provide a deeper understanding of the condition.
• Discoloration of clothing: Body odor can sometimes lead to yellowish or brownish stains on clothing, particularly in the underarm area.
• Itchiness or skin irritation: Excessive sweating and bacterial growth can sometimes lead to skin irritation, itching, or even a rash in the affected areas.

Before understanding the exact cause behind body odor, it is important to know about sweat glands and their function:

What are sweat glands?

Sweat glands are small tubular structures of the skin that produce sweat. They are of two types:

Eccrine

• Present throughout the body, most prominently on the soles of the feet, palms, forehead, cheeks, and in the armpits.
• Help in maintaining body temperature.
• Produce large volumes of watery, usually odorless sweat.

Apocrine

• Connected to the hair follicles situated in the groin and axillary regions.
• Begin functioning during puberty in response to the activation of sex hormones.
• Secretes a thick, viscous, usually invisible fluid that produces a characteristic potent smell when it comes in contact with skin bacteria.
• Usually, the apocrine sweat and bacteria get washed away by regular (eccrine) sweat, which doesn't stink.

What causes body odor?

Body odor is caused by the contact between sweat and bacteria that reside on the skin. It can be due to:

• The presence of a large amount of bacteria on the skin.
• Excessive production of apocrine sweat.

These two processes can be triggered by several factors discussed under the “risk factors” section.

Apart from sweat (skin), the odorous substances can also be emitted through:

• Saliva.
• Breath.
• Reproductive fluids.
• Urine.

Risk Factors of Body Odor

Certain factors increase the likelihood of developing strong body odor, even though it is natural. These risk factors include:

• Poor hygiene: Inadequate personal hygiene, such as infrequent bathing or not washing specific areas of the body properly, can accumulate sweat and bacteria, exacerbating body odor.
• Age: Apocrine sweat is the main cause of body odor, so the activation of apocrine glands during puberty makes adults more prone to developing it.
• Geographical location: Individuals living in hot, humid tropical climates are more susceptible to body odor due to excessive sweat production.
• Obesity: People who are overweight or obese may have increased skin folds and areas where sweat and bacteria can accumulate, leading to more pungent body odor.
• Hormonal changes: Hormonal fluctuations, such as those occurring during puberty, menstruation, or menopause, can affect sweat composition and increase bacterial activity, contributing to more pungent body odor.
• Excessive sweating: Excessive sweating, known as hyperhidrosis, can lead to increased moisture on the skin's surface, providing more material for bacteria to metabolize and produce a more pungent odor.
• Dietary factors: Certain foods, such as garlic, onions, spices, and alcohol, can influence the odor of sweat because their components are released through sweat.
• Genetics: Genetics can influence an individual's unique body odor profile, making some people more prone to producing certain odors.
• Stress and anxiety: Emotional stress and anxiety can trigger the release of stress hormones, which may affect sweat composition and contribute to stress-induced body odor.
• Medical conditions: Certain medical conditions may cause changes in sweat composition or increase sweating, contributing to body odor. This includes:
  • Sinusitis
  • Gastroesophageal reflux disorder (acid reflux)
  • Liver disease
  • Diabetes
  • Kidney failure
  • Trimethylaminuria (fish odor syndrome)
  • Phenylketonuria (accumulation of a chemical called phenylalanine in the body)
  • Hypermethioninemia (excessive buildup of a protein building block (amino acid) called methionine in the blood)
• Use of certain medications: Some medications can alter sweat composition or increase sweating, leading to changes in body odor. This can include medications such as:
  • Penicillin
  • Bromides
  • Dupilumab

Generally, body odor indicates improper skin care and hygiene. However, in some instances, it can be due to underlying medical conditions. Therefore, it is essential to undergo diagnostic testing. The diagnostic tests include:

1. Obtaining a medical history
   A thorough medical history helps identify the exact cause of the body odor. The information regarding the following points is captured through patient interaction:
   • Sweat patterns
   • Hygiene patterns
   • Previous history of diseases
   • Current medical conditions
   • Medications
   • Family history of body odor
2. Physical examination
   The healthcare provider will conduct a physical examination, focusing on areas where bromhidrosis is most noticeable, such as the underarms, groin, and feet. They may also assess skin conditions, sweat patterns, and any signs of underlying medical issues.
3. Starch-iodine test
   In some cases, the healthcare provider may perform a starch-iodine test to visualize areas of increased sweating, which can help determine the extent and distribution of the condition.
4. Ruling out underlying medical conditions
   The healthcare provider may order additional tests or investigations to rule out any underlying medical conditions contributing to the foul-smelling sweat. These may include blood tests, urine tests, or imaging studies, depending on the suspected underlying cause.

Body odor is primarily caused by the bacteria on your skin breaking down sweat and producing odorous compounds. While you can't eliminate sweating or the presence of bacteria on your skin, there are several steps you can take to prevent or reduce body odor:

1. Maintain good hygiene
   • Shower daily with soap and water to remove sweat, dirt, and bacteria.
   • Pay special attention to areas prone to body odor, such as the armpits, groin, and feet.
   • Use an antibacterial soap or a soap containing tea tree oil to help reduce the growth of odor-causing bacteria.
2. Choose breathable clothing
   • Wear natural fabrics like cotton, linen, and wool, which allow your skin to breathe.
   • Avoid tight-fitting clothing that can trap sweat and create an environment for bacteria to thrive.
3. Practice proper underarm care
   • Keep your underarms dry by patting them with a towel after showering.
   • Remove underarm hair, as it can trap sweat and odor.
   • Here are some everyday ingredients that help reduce underarm sweating.
4. Wash your clothes regularly
   • Dirty clothes can harbor odor-causing bacteria. Wash your clothes after each use.
   • Use a laundry detergent designed to remove odors.
5. Manage your diet
   • Certain foods and drinks, like garlic, onions, spicy foods, and alcohol, can contribute to body odor.
   • Stay hydrated by drinking plenty of water to help dilute sweat and reduce odor.
6. Manage stress
   • Stress can trigger excessive sweating and exacerbate body odor. Practice stress-reduction techniques like meditation, yoga, or deep breathing exercises.
   • Know from our expert the best ways to manage stress and anxiety.

Treating body odor or bromhidrosis depends on the underlying cause and severity of the condition. The main goal of therapy involves:

• Reducing bacterial overgrowth
• Maintaining a dry environment on the skin
• Treatment of coexisting skin and other medical conditions

These are achieved through:

1. Over-the-counter products
   • Antiperspirant: It helps decrease sweating by clogging the sweat ducts.
   • Deodorant: It helps in masking the odor.
   • Antibacterial soaps can help reduce the number of bacteria on the surface of the skin, which can lead to unpleasant-smelling sweat. Using cleansers containing benzoyl peroxide can also help.
2. Topical antibiotics: In cases where bacteria play a significant role in bromhidrosis, topical antibiotics may be prescribed by a healthcare professional to reduce bacterial activity on the skin. Some common examples include:
   • Clindamycin
   • Erythromycin
3. Botox injections: For severe cases of underarm sweating, Botox injections can be considered. Botox blocks the nerves stimulating sweat glands and reducing sweat production in the treated area.
4. Iontophoresis: A small electric current is passed through the skin to reduce sweating. This method is used when excessive eccrine sweat contributes to body odor.
5. Surgery: There are two approaches:
   • Localized destruction: In this, surgeries are performed to destroy sweat glands in the armpit areas. It involves:
     • Liposuction: Sweat glands are present in the layer of fat under the skin. This method involves removing that layer using a suction device. Due to superior results and fewer risks, this method is now mostly replaced by Botox injections.
     • Laser: Fat under which the sweat glands are present is liquefied using laser energy. The debris of sweat glands and fat are later removed by liposuction.
     • Curettage: During this procedure, the undersurface of the skin (which contains sweat glands) is scraped using a suction tube and curette.
   • ETS (endoscopic thoracic sympathectomy): It includes the removal of nerves that cause sweating.

The following general tips can help manage body odor:

1. Maintain body hygiene
   • Shower regularly, especially after profuse sweating.
   • Thoroughly dry your skin, focusing on moisture-prone areas.
2. Choose clean, breathable attire
   • Wear clean clothes every day, particularly undergarments and socks.
   • Opt for loose, breathable clothing like cotton and linen.
   • Avoid tight-fitting garments that trap moisture.
3. Ensure foot care
   • Wash your feet daily with soap and water.
   • Dry them thoroughly, especially between the toes.
   • Wear clean, dry, moisture-wicking socks. Change them regularly.
   • Prefer open footwear like floaters that allow the skin to breathe.
   • Regularly rotate shoes to air them out.
4. Use antiperspirants and deodorants
   • Apply antiperspirants or deodorants to clean, dry skin to help reduce sweating and control body odor.
5. Carry wipes or towelettes
   • Keep moist wipes or towelettes handy to freshen up during the day, especially if you are prone to sweating.
6. Stay hydrated
   • Drink at least 8-10 glasses of water to help regulate body temperature and reduce excessive sweating.
7. Avoid certain foods
   • Be mindful of your diet. Certain foods like garlic, onions, and spicy dishes can produce more pungent body odor. Avoiding these foods may help manage body odor.
8. Add greens to your diet
   • Veggies such as spinach, kale, and celery are good for your health and have a deodorizing effect. Research has shown that chlorophyll in green vegetables helps reduce body odor.
9. Manage stress
   • Stress can exacerbate sweating and body odor. To promote relaxation, practice stress-relief techniques such as meditation, yoga, or deep breathing exercises.
