Hidradenitis Suppurativa (HS) is a chronic inflammatory skin condition characterized by painful, recurring nodules and abscesses, typically forming in areas like the armpits and groin. The persistent, often unpleasant odor is a common symptom of HS, resulting from the breakdown of sweat and discharge (exudate) by bacteria within the lesions. This bacterial activity produces volatile organic compounds that cause the smell. This odor is a byproduct of the disease process itself, not a sign of poor hygiene. Controlling this odor involves a multi-pronged approach that addresses both immediate symptoms and the underlying inflammation driving the disease.
Immediate Topical and Hygiene Strategies
Managing the bacterial load on the skin is the primary step toward controlling HS-related odor. A gentle but consistent daily cleansing routine is important, focusing on affected areas without causing further irritation or friction. Using a non-abrasive, fragrance-free cleanser helps remove surface bacteria and debris without stripping the skin’s protective barrier.
Antiseptic washes are often recommended to reduce the number of odor-causing bacteria. Over-the-counter options include cleansers containing chlorhexidine gluconate (typically 4%) or benzoyl peroxide (5% to 10%). These have broad-spectrum antimicrobial properties. Chlorhexidine should be applied briefly before rinsing thoroughly, and benzoyl peroxide washes can also help reduce bacteria and open clogged pores.
Another approach to reducing surface bacteria is a diluted bleach bath, done up to twice a week. This involves adding a small, measured amount of household bleach (e.g., ¼ to ½ cup) to a full bathtub of water, creating a low concentration of sodium hypochlorite. Soaking the affected areas for about ten minutes can help decolonize the skin of odor-producing bacteria. Always rinse off with fresh water afterward and consult a healthcare provider before trying this method.
For daily maintenance, specialized deodorizing products designed for sensitive skin may offer relief. Standard antiperspirants should be avoided over active lesions as they can irritate inflamed skin or block drainage. The goal of these topical strategies is to reduce the bacterial environment that metabolizes the exudate, thereby minimizing the creation of the compounds responsible for the smell.
Specialized Wound and Drainage Management
Once the skin is cleansed, a strategy to contain and absorb the inevitable discharge (exudate) from open lesions is necessary to control odor. The physical management of exudate is paramount because the breakdown of inflammatory components in the drainage contributes directly to the unpleasant smell. Choosing highly absorbent dressings is the primary action to wick away moisture and prevent it from sitting on the skin or clothing.
Specialized dressings are effective choices for wounds with moderate to heavy drainage. These include foam, superabsorbent pads, or calcium alginate. Superabsorbent dressings are designed to manage high volumes of exudate, keeping the wound environment drier and reducing bacterial proliferation. For strong odors, dressings containing activated charcoal or silver may be helpful, as these materials neutralize odor-causing compounds and bacteria.
Managing deep lesions and chronic inflamed tracts (sinus tunnels) requires careful technique. Non-adherent dressings are preferred to prevent painful removal and irritation to the surrounding skin. Barrier creams can be applied to healthy skin around draining areas to protect it from the continuous discharge. Frequent dressing changes are necessary to prevent saturation, which commonly causes odor.
Addressing the Underlying Disease
For long-term, comprehensive odor control, the underlying inflammatory activity of Hidradenitis Suppurativa must be addressed, as this is the source of the draining lesions. This requires consulting a dermatologist to initiate systemic treatments that reduce the frequency and severity of disease flares. Oral antibiotics are commonly prescribed for their anti-inflammatory and antibacterial properties, with combinations like clindamycin and rifampicin often showing effectiveness.
More advanced disease often requires systemic therapies that modulate the immune system, such as biologic medications. Biologics, including adalimumab, work by targeting specific inflammatory pathways, such as tumor necrosis factor-alpha, which are overactive in HS. By calming chronic inflammation, these therapies reduce the formation of new lesions and the overall amount of inflammatory discharge, leading to a significant reduction in associated odor.
Medical procedures can also permanently remove or reduce the chronic sources of odor. A procedure called deroofing involves surgically removing the “roof” of a chronic tunnel or abscess to expose the tract, allowing it to heal from the inside out and eliminating the area where bacteria accumulate. Carbon dioxide laser therapy can also be used to precisely excise affected tissue, including the hair follicles and sweat glands implicated in the disease process. These interventions tackle the root cause of the discharge, offering a definitive solution for persistent HS-related odor.
