What causes fungal infections?
Different types of fungus cause a variety of fungal infections:
Athlete’s foot, jock itch, and ringworm are caused by a fungus called tinea.
Most yeast infections, such as vaginal thrush, oral thrush, and fungal gastroenteritis, are caused by a fungus called Candida albicans. Fungus can also cause fungal infections of the lungs due to inhaled fungal spores.
Certain factors or conditions can result in an overgrowth of fungus in the body. These include:
Taking antibiotics. Antibiotics can kill off “healthy” bacteria in the body, as well as bacteria that cause disease. When antibiotics kill the healthy bacteria, the normal balance of microorganisms in the mouth, vagina, intestines, and other places in the body is altered, resulting in an overgrowth of Candida albicans or other fungi.
Having a weakened immune system due to certain conditions, such as HIV/AIDS or taking steroid medications or chemotherapy
- Having a weakened immune system due to certain conditions, such as HIV/AIDS, organ transplant recipient, or taking steroid medications or chemotherapy
Having high blood sugar due to diabetes, which provides food for Candida albicans and encourages its overgrowth
Fungal infections can also be passed from a pregnant woman to her infant during vaginal delivery or breastfeeding.
What are the risk factors for fungal infections?
A number of factors increase the risk of developing fungal infections. Not all people with risk factors will develop fungal infections. These factors include:
- Being very young or very old
- Douching or using feminine deodorants or scented tampons
- Exposure to contaminated surfaces especially shower facilities, swimming pools, hot tubs/spas.
- Having diabetes
- Having a weakened immune system due to such conditions as HIV/AIDS, or taking steroid medications or chemotherapy
