Armpit yeast infection, also known as candidiasis is a fungal skin infection that can cause discomfort and irritation in the skin folds of your armpits. This condition is caused by the overgrowth of a yeast called Candida. In this article, we will explore the symptoms, causes, and treatment options for armpit yeast infections.

Symptoms of armpit yeast infections

The most common symptom of an armpit yeast infection is a bright red rash in the skin folds of your armpit. This armpit rash may appear in patches of different shapes and sizes, and it is usually intensely itchy. In addition to itching, you may also experience a burning sensation in the affected area. Other symptoms may include small pimple-like spots, scaly skin, and swelling.

It’s important to note that armpit yeast infections typically do not cause a smell or odor. However, if your infection is associated with a skin condition called intertrigo, you may notice a musty smell. Intertrigo is a common inflammatory skin condition that occurs when the skin folds rub together, leading to heat and moisture buildup.

Causes of armpit yeast infections

Armpit yeast infections are primarily caused by an overgrowth of Candida yeast. Candida thrives in warm and moist environments, which creates an ideal breeding ground for its growth. Several common causes can contribute to the development of this skin infection, including:

  • Hot and humid weather: Excessive sweating in hot and humid conditions can create moist areas of skin and a favorable environment for the growth of Candida
  • Tight clothing: Wearing tight-fitting clothes can trap moisture and heat, promoting the growth of yeast
  • Poor hygiene: Inadequate hygiene practices, such as infrequent bathing or not drying the underarms properly, can contribute to the development of yeast infections
  • Infrequent undergarment changes: Wearing the same undergarments for an extended period can lead to moisture buildup and increase the risk of infection
  • Skin conditions: Certain skin conditions like psoriasis, eczema and intertrigo can create an environment conducive to the growth of yeast
  • Certain medical conditions: Individuals with weakened immune systems, such as those with HIV/AIDS, diabetes, or undergoing chemotherapy, are more susceptible to armpit yeast infections
  • Antibiotic use: Taking antibiotics can disrupt the balance of bacteria on the skin, allowing yeast to overgrow

Is an armpit yeast infection contagious?

Armpit yeast infections are typically not contagious. However, individuals with weakened immune systems have a higher risk of contracting the infection. It is important to practice good hygiene and avoid sharing personal items to prevent the spread of infection.

Diagnosis of armpit yeast infections

To diagnose an armpit yeast infection, a healthcare professional such as a dermatologist may examine the affected area and collect a sample for laboratory testing. The sample is typically obtained by gently scraping the skin or taking a swab. Laboratory tests can confirm the presence of Candida infection and help determine the most appropriate treatment.

Treatment options for armpit yeast infections

The treatment of armpit yeast infections typically involves a combination of topical antifungal medications and lifestyle modifications. Here are some common treatment options:

  • Antifungal creams: Topical antifungal creams or ointments such as clotrimazole, ketoconazole or miconazole, can be bought over the counter and applied directly to the affected area to eliminate the yeast
  • Antifungal powders or sprays: These products can help keep the affected area dry and prevent further yeast growth
  • Good hygiene practices: Maintaining proper hygiene, including regular bathing, drying the armpits thoroughly, using antiperspirants, and wearing clean clothes, can help prevent the recurrence of yeast infections
  • Loose-fitting clothing: Opt for loose-fitting clothes made of breathable fabrics to promote air circulation and reduce moisture buildup
  • Avoiding irritants: Avoid using harsh soaps, perfumes, or deodorants that may irritate the skin and worsen the infection

Prevention of armpit yeast infections

The recommendations will vary widely, depending on the underlying cause. Here are some tips to prevent their occurrence:

  • Keep the armpit area clean and dry
  • Change undergarments frequently, especially after sweating
  • Wear loose-fitting clothes made of breathable materials
  • Avoid sharing personal items like towels or clothing
  • Maintain a healthy immune system through a balanced diet and regular exercise

When to seek medical attention

If your symptoms worsen or persist despite home remedies, it is advisable to seek medical attention. A healthcare professional can provide a proper diagnosis and recommend appropriate treatment options based on your specific condition.


Armpit yeast infections can cause discomfort and itchiness, but with proper treatment and preventive measures, they can be managed effectively. Maintaining good hygiene, wearing breathable clothing, and using antifungal medications can help alleviate symptoms and prevent the recurrence of these fungal infections. If you suspect an armpit yeast infection, consult your healthcare provider for an accurate diagnosis, tailored treatment plan and medical advice.
