Intertrigo (Skin Fold Rash & Yeast Infections)

Intertrigo is a common skin condition that develops in areas where skin rubs together, such as beneath the breasts, abdomen, armpits, and groin. It often causes redness, itching, burning, and irritation, particularly in warm or moist environments. Although uncomfortable, intertrigo can usually be managed effectively with proper skin care and targeted treatment.

At NP Healthcare Group, our experienced healthcare providers offer personalized evaluations and treatment options to help relieve discomfort, address underlying causes, and prevent recurring skin irritation.

What is intertrigo?

Intertrigo is inflammation of the skin that occurs where skin surfaces touch or rub together. It commonly develops in warm, moist areas of the body.

Commonly affected areas include:

• Beneath the breasts
• Abdominal skin folds
• Armpits
• Groin and inner thighs
• Between the buttocks
• Other areas where skin folds overlap

Intertrigo may develop from friction and moisture alone or become complicated by yeast or bacterial infections.

What are the symptoms of intertrigo?

Symptoms can vary depending on the severity and whether an infection is present.

Common symptoms include:

• Red or discolored patches of irritated skin
• Itching, burning, or stinging
• Moist or tender skin
• Peeling, cracking, or scaling
• An unpleasant odor in some cases
• Small surrounding bumps or pustules when yeast is involved

Symptoms may worsen with sweating, heat, or prolonged moisture exposure.

What causes intertrigo?

Intertrigo develops when friction, moisture, and reduced airflow irritate the skin.

Contributing factors may include:

• Excessive sweating
• Hot or humid weather
• Skin folds that retain moisture
• Tight or non breathable clothing
• Obesity
• Diabetes
• Yeast overgrowth, particularly Candida
• Bacterial infections

Identifying contributing factors can help reduce recurring flare-ups.

Is intertrigo a fungal infection?

Not always. Intertrigo is primarily an inflammatory skin condition caused by friction and moisture.

However, yeast, particularly Candida, can grow in affected areas and cause a secondary infection known as candidal intertrigo.

Your healthcare provider can help determine whether the rash is caused by irritation, yeast, bacteria, or another skin condition.

How is intertrigo treated?

Treatment depends on the underlying cause and severity of the rash.

Your provider may recommend:

• Keeping affected skin folds clean and thoroughly dry
• Wearing loose, breathable clothing
• Using moisture-absorbing materials to reduce friction
• Applying protective barrier products
• Prescription antifungal creams such as nystatin or clotrimazole when yeast is present
• Additional medication if bacterial infection or significant inflammation is identified

Proper skin care and treatment of contributing conditions can help prevent recurrence.

Can intertrigo go away on its own?

Mild intertrigo may improve when moisture and friction are reduced. However, persistent irritation or an associated fungal infection may require treatment.

Without addressing contributing factors, symptoms can return, particularly during warm weather or periods of increased sweating.

Is intertrigo contagious?

Intertrigo itself is not contagious because it develops primarily from skin irritation caused by friction and moisture.

When yeast is involved, the infection usually results from an overgrowth of organisms already present on the skin rather than transmission from another person.

How can I prevent intertrigo from returning?

Preventive measures include:

• Keeping skin folds clean and dry
• Drying thoroughly after bathing
• Changing out of damp or sweaty clothing promptly
• Wearing breathable, moisture-wicking fabrics
• Reducing friction between skin surfaces
• Managing excessive sweating
• Maintaining appropriate blood glucose control if you have diabetes
• Consistent preventive care may significantly reduce flare-ups.

Can intertrigo be treated through telehealth?

Yes. Many uncomplicated cases of intertrigo can be evaluated and treated through telehealth.

At NP Healthcare Group, our providers can review your symptoms, assess photographs of affected areas when appropriate, and recommend treatment based on your clinical presentation.

If the diagnosis is uncertain, symptoms are severe, or additional testing is necessary, an in-person examination may be recommended.

When should I seek medical attention?

Schedule an appointment if you experience persistent redness, itching, burning, or irritation in your skin folds, particularly if the rash keeps returning.

Seek prompt medical evaluation if you develop:

• Increasing pain, swelling, or warmth
• Pus, drainage, or open sores
• A rapidly spreading rash
• Fever or other signs of infection
• Symptoms that worsen despite treatment

Early evaluation can help identify secondary infections and prevent further skin complications.
