There are different strains of yeast naturally present in certain parts of the human body and these strains do not pose a threat unless they start to multiply. The most commonly discussed yeast infection, one that causes much discomfort, is the vaginal yeast infection. The best way to avoid these kinds of infections is to have a basic idea of what causes them. Following are some of the most common causes of yeast infections.
Hormonal Imbalance - Women who are suffering from a hormonal imbalance are more susceptible to yeast infections. There are numerous reasons that can cause hormonal changes in women. It is thought that high levels of estrogen in the body can give rise to yeast infections. Such a spike in estrogen and hormonal fluctuations is common when a woman is ovulating. Women using birth control pills or other hormonal therapy might have a spike in their estrogen levels, making women using these to be more susceptible to candidiasis. High estrogen levels is believed to be a prominent cause of yeast infection in pregnant women.
High Blood Sugar Levels - Diabetes mellitus in women heightens the risk of them developing yeast infections. This is attributed to the fact that diabetes affects the pH balance in the vagina. The vaginal pH normally ranges from 3.8 to 4.5. There is a friendly bacteria in the vagina that plays a role in maintaining a slightly acidic environment that actually prevents yeast cells from growing, which is suppressed by an acidic environment in the vagina. In the case of diabetic women, vaginal secretions containing high levels of sugar work to raise the vaginal pH. This in turn makes diabetics more susceptible to developing yeast infections. This also means that excessive consumption of high sugar foods can lead to the growth of yeast even in non-diabetic women as well.
Usage of Antibiotics - The most widely used treatments for bacterial infections are antibiotics. These types of drugs can kill harmful bacteria and stop them from multiplying, however they also kill the beneficial bacteria in the process. Once the pH balance is disrupted as the friendly bacteria decreases, yeast cells are free to grow rapidly. This disruption of balance between good bacteria and yeast cells can make women more vulnerable to developing oral thrush, a yeast infection of the oral cavity, and vaginal candidiasis also known as a vaginal yeast infection.
Wearing of Very Tight Clothing - It turns out that many women suffer from vaginal yeast infections after wearing tight clothing. Clothing that is too tight can irritate the vagina. Tight clothing can also lead to excessive sweating, creating dampness in which a yeast infection is likely to develop. Wearing damp underclothing can also become a breeding ground for yeast cells to multiply. Precautions should be taken to keep the genital region dry and clean. Perfumed feminine sprays should not be used as they can be very irritating to the vaginal area. Using water to clean the region should be more than enough.
