• Yeast Infections (Candidiasis)

(A common fungal infection caused by an overgrowth of yeast on the skin)

What Is Candidiasis?

Candidiasis is a fungal infection caused by an overgrowth of Candida yeast, which normally lives on the skin and body. When the skin environment becomes warm, moist, irritated, or imbalanced, yeast can overgrow and cause infection.

Yeast infections can affect:

  • Skin folds
  • Groin
  • Under breasts
  • Armpits
  • Mouth (oral thrush)
  • Nails
  • Genital areas

What Does a Yeast Infection Look Like?

Common symptoms include:

  • Bright red rash
  • Itching or burning
  • Moist or shiny irritated skin
  • Small surrounding “satellite” bumps or pustules
  • Cracking or soreness in skin folds
  • White patches in the mouth (oral thrush)

Who Is More Likely to Get Candidiasis?

Risk factors include:

  • Warm or humid environments
  • Sweating
  • Diabetes
  • Antibiotic use
  • Obesity
  • Immune suppression
  • Skin friction
  • Moist skin folds

How Is Candidiasis Diagnosed?

Diagnosis is often made by skin examination. In some cases, testing or skin scraping may be performed to confirm fungal infection and rule out eczema, psoriasis, or bacterial infection.

How Is Candidiasis Treated?

Treatment depends on location and severity.

Common treatments include:
  • Topical antifungal creams or powders
  • Oral antifungal medication in selected cases
  • Keeping the area dry
  • Reducing friction and moisture
  • Managing contributing conditions such as diabetes

Oral thrush may require antifungal mouth rinses or oral medication.

Frequently Asked Questions

Is candidiasis contagious?

Usually not in the way common infections spread, but yeast overgrowth can sometimes spread to nearby skin areas.

No. Yeast normally lives on the skin. Moisture, friction, antibiotics, and medical conditions often contribute.

Intertrigo is inflammation in skin folds. Candida yeast commonly grows in these irritated moist areas.

es. Elevated blood sugar can increase risk of recurrent candidiasis.

Oral thrush is a Candida yeast infection inside the mouth that causes white patches and soreness.

Yes. Steroids may temporarily reduce redness while allowing fungal overgrowth to worsen.

Yes. Recurrence is common if moisture, friction, diabetes, or antibiotics continue to contribute.

Seek evaluation if the rash is painful, recurrent, widespread, unclear, or not improving with treatment.
