here are some tips on the causes of yeast infection, just to give you a clue and maybe you can pinpoint by yourself which ones are applicable to you.
Yeast infection is mainly brought about by the overgrowth of the fungus called Candida albicans. Here are some conditions which can foster the growth and the overpopulation of the Candida yeast in the body, especially in the vagina:
• Overuse of antibiotics.
Antibiotics can kill the good bacteria which are essential in maintaining the health of your body. Say, you have an ear infection. If you take antibiotics to deal with the discomfort in your ear, you kill the unwanted bacteria that cause your ear infection. But by doing this, you are also killing the good bacteria in other parts of the body like the digestive tract or the vagina.
• Diabetes
The yeast fungus Candida albicans feeds on sugar, so people who have high levels of sugar in their blood have greater chances of acquiring yeast infection.
• Birth control medications and hormonal changes in women
The vaginal walls are normally covered with some protective mucous tissue. The thickness of this mucous membrane depends on the balance of sex hormones present in a woman's body. This hormonal balance might be disturbed during menstrual cycle, during pregnancy, during menopause, or when taking contraceptive pills. When the mucous tissue becomes very thin, the vagina becomes vulnerable to infection.
• Clothing
Wearing tight jeans, synthetic underwear (those made of Lycra or nylon), pantyhose, and wet clothes fosters the growth of yeast fungi. The heat and moisture trapped by these tight and synthetic clothing makes your crotch a suitable place for Candida to thrive in.
• Steroids
People who use steroids for their arthritis or asthma were seen to develop yeast infections in their oral cavities.
• Chemicals
Inks, dyes, and perfumes found in commercial douches, hygienic sprays, and some menstrual pads, panty-liners and colored tissue papers can trigger allergic reaction and are harmful to the vaginal environment. Soap also damages the vaginal mucous membrane and disrupts the normal pH level of the vagina.
• Sexual activity
Yeast infection is not primarily caused by sexual contact. However, the Candida fungus may then be transferred to another person upon sexual contact.
Condoms contain chemicals which are not good for the vaginal environment. Also, women who may have allergic reaction to latex (the material that condom is made of) might become prone to yeast infection. Rough sexual experience, like the lack of lubrication during sexual activity, can cause injury to the vaginal membranes, thus making it prone to yeast infection.
Males who have had sexual encounter with women who have yeast infection may also develop penile thrush.
