Vaginal yeast infections are caused by fungus candida. You should know that your vagina naturally contains a mixture of yeast, including the candida, and bacteria. The problems occur when this yeast starts to overgrow.
Too much yeast in the vagina causes itching, swelling, thick and clumpy discharge, and burning. There are a few things that could cause this overgrowth of yeast to occur inside the female sexual organ.
Using certain antibiotics can alter the bacteria production or the vagina and change the pH of the vagina. Pregnancy is a common weakness when it comes to a yeast infection as it alters the hormones of the female body. If you have a weak or impaired immune system changes in the vaginal pH can be more likely than that in a person with a healthy immune system.
Taking oral contraceptives or hormone therapy is another factor that will increase the estrogen levels of the body, which will in turn increase the production of yeast. Lastly, uncontrolled diabetes can also cause overproduction of yeast and you should seek medical assistance if this is the case.
The last way you can get a yeast infection is through sexual contact. Even oral sex can spread the yeast infection into the mouth and throat in addition to the sexual organs.
