What Is Intertrigo?

Intertrigo is a skin condition that occurs in areas where skin folds rub together, causing inflammation, redness, and irritation. It most commonly affects warm, moist areas of the body such as the armpits, groin, under the breasts, between the thighs, and in abdominal skin folds.

The condition can be worsened by sweating, heat, poor hygiene, or tight clothing, and it may become infected with fungus or bacteria, especially Candida (yeast).

What Causes Intertrigo?

Intertrigo is usually caused by a combination of friction, moisture, and lack of air circulation. Specific contributing factors include:

• Obesity – more skin folds can trap moisture
• Sweating – especially in hot, humid environments
• Tight clothing – causes friction and limits airflow
• Poor hygiene – can lead to bacterial or fungal overgrowth
• Diabetes – increases susceptibility to infections
• Immobility – bed-bound individuals are at higher risk

Secondary infections by yeast (Candida albicans), bacteria (such as Staphylococcus aureus or Streptococcus), or fungi (like dermatophytes) often complicate the condition.

What Are the Symptoms of Intertrigo?

Symptoms typically appear in the skin folds and may include:

• Redness and inflammation
• Itching or burning sensation
• Soreness or pain
• Cracked or peeling skin
• Foul-smelling discharge (if infected)
• Rash that spreads or worsens in heat

The skin may feel warm, tender, or moist to the touch.

How Is Intertrigo Diagnosed?

Intertrigo is usually diagnosed clinically through physical examination. A healthcare provider may also:

• Take a skin swab or sample to check for fungal or bacterial infection
• Use a Wood’s lamp to detect fungal involvement
• Order blood sugar tests if diabetes is suspected

How Is Intertrigo Treated?

1. General Care:

• Keep the affected area clean and dry
• Gently cleanse the skin with mild soap and water
• Pat the area dry with a soft towel—do not rub

2. Topical Treatments:

• Barrier creams or powders to reduce friction and moisture
• Antifungal creams (e.g., clotrimazole or miconazole) for yeast infections
• Topical antibiotics for bacterial infection
• Mild corticosteroids (short-term use only) to reduce inflammation

3. Lifestyle Modifications:

• Wear loose-fitting, breathable clothing
• Maintain a healthy weight
• Improve airflow to affected areas (e.g., with absorbent fabrics or drying sheets)
• Manage underlying conditions like diabetes

4. Medical Follow-up:

• Persistent or worsening symptoms may require prescription treatments or dermatologist referral

Is Intertrigo Contagious?

Intertrigo itself is not contagious, but if the area becomes infected, the bacteria or fungus involved may be spread through direct contact or shared personal items.

Can Intertrigo Be Prevented?

Yes. Prevention focuses on minimizing moisture and friction:

• Keep skin folds dry (use absorbent powders or breathable materials)
• Practice good hygiene
• Avoid tight or non-breathable clothing
• Use antifungal powders if prone to yeast infections
• Treat any underlying conditions, such as obesity or diabetes
