What is an armpit fungal infection?

Armpit fungus, also known as thrush, is an infection caused by yeast fungi that thrive in warm and moist areas. This type of fungal infection can affect the skin under the arms, causing symptoms such as itching, redness, flaking and soreness.

Underarm fungus can be bothersome and affect your daily comfort. It's important to understand the causes of the fungal infection in order to effectively treat and prevent it. In this section, we will explore how fungal infections develop and how they affect the underarm area.

Causes to fungus in the armpits

Various factors and causes that can contribute to the development of underarm fungus:

  1. Moisture and heat: The warm and humid environment under the arms creates optimal conditions for fungal growth.
  2. Weakened immune system: A weakened immune system can make it harder for the body to fight fungal infections.
  3. Insufficient hygiene: Failure to clean and properly wipe underarms can create a favourable environment for fungal growth.
  4. Tight-fitting clothing: Tight-fitting clothing can prevent air circulation and increase humidity, which can promote fungal growth.
  5. Sharing personal items: Sharing towels, clothing or personal care products with someone who has thrush can lead to the transmission of infection.

It's important to be aware of these factors to better understand how to prevent and treat underarm fungus.
