Bromhidrosis (Body Odour Condition) – Consultant Dermatology Treatment in London

Understanding bromhidrosis

Bromhidrosis is the medical term for chronic, unpleasant body odour. While occasional odour after exercise is normal, bromhidrosis occurs when bacterial breakdown of sweat produces persistent or excessive smell that is noticeable in daily life. It is not dangerous to health but can have significant social and emotional consequences. Patients often describe feeling anxious in public or avoiding social situations because of embarrassment.

The condition most often involves the armpits, feet, and groin—areas rich in sweat glands where bacteria thrive. Distinguishing bromhidrosis from normal perspiration is important, as effective treatments are available.

Causes and mechanism

Human sweat itself is odourless. The smell arises when sweat interacts with bacteria on the skin’s surface. There are two main forms:

• Apocrine bromhidrosis: caused by apocrine sweat glands (present in armpits and groin). Bacteria break down proteins and lipids, producing pungent odours.
• Eccrine bromhidrosis: less common, due to eccrine sweat mixing with skin bacteria, or influenced by diet, medications, or systemic disease.

Risk factors include poor hygiene, excessive sweating (hyperhidrosis), obesity, diabetes, some medications, fungal infections, and wearing non-breathable footwear or clothing. Psychological stress can also worsen symptoms by increasing sweat production.

Who is affected?

Bromhidrosis can affect anyone but is more common after puberty, when sweat gland activity increases. Men are slightly more affected than women due to higher apocrine activity. People with hyperhidrosis or chronic skin infections are at higher risk. Cultural and dietary habits (such as high consumption of spices, garlic, or alcohol) may also contribute.

Diagnosis

Diagnosis is clinical, based on history and examination. A dermatologist will ask when the odour occurs, which body areas are affected, and whether hygiene measures help. Conditions such as fungal foot infection, metabolic disorders, or rare genetic syndromes may be considered. In most cases, tests are not needed, though swabs may be taken if infection is suspected.

Management and treatment options

Bromhidrosis treatment aims to reduce sweat, control bacteria, and improve quality of life. Options include:

• Lifestyle measures: daily washing with antibacterial soaps, frequent clothes washing, wearing breathable fabrics, cotton socks, and ventilated shoes.
• Antiperspirants: aluminium-based roll-ons or sprays reduce sweating and bacterial growth.
• Topical antibiotics: clindamycin or erythromycin lotions may help in recurrent cases.
• Oral antibiotics: sometimes used short-term for resistant infections.
• Injectables (botulinum toxin): reduce sweating for several months, particularly in the armpits.
• Laser and energy devices: selective destruction of sweat glands can give longer-term improvement.
• Surgical options: removal of sweat glands in severe, treatment-resistant cases.

At Skinhorizon, we combine medical and aesthetic approaches, tailoring treatment to each individual. Many patients achieve long-lasting confidence after targeted interventions.

Aftercare and prevention

After treatment, good hygiene and lifestyle adjustments help maintain results. Patients may be advised to:

• Use daily antibacterial washes and deodorants.
• Shave or trim underarm hair to reduce bacterial build-up.
• Wear breathable, moisture-wicking fabrics.
• Rotate footwear and use absorbent insoles for foot odour.
• Manage contributing conditions such as hyperhidrosis or fungal infections.

Impact on wellbeing

While bromhidrosis is medically harmless, it can cause significant psychological distress. Feelings of shame, anxiety, and reduced self-esteem are common. Recognising the emotional toll is just as important as managing the physical symptoms. At Skinhorizon, we provide supportive, discreet, and professional care to help restore both confidence and comfort.
