Vaginal candidiasis (thrush) is a common yeast infection caused by an overgrowth of a fungus called Candida albicans. Under normal circumstances, this yeast can live in the body with no issues, but under certain conditions, it can overgrow and cause discomfort. Three out of four women experience a yeast infection at some point in their lives [1], and about 138 million suffer from recurring yeast infections every year [2].
Why is this happening?
The vagina has a microbiological system that maintains a balance between the microorganisms that inhabit it to protect against candidiasis and other infections. If this balance is disrupted, the presence of good bacteria decreases, and conditionally pathogenic microflora, including yeast-like fungi, can overgrow. This usually happens when the immune system is weak due to antibiotics, hormonal drugs, conditions such as diabetes, or due to the overuse of products for intimate hygiene. Candidiasis does not belong in the category of sexually transmitted diseases (STDs), but a woman can pick it up from a partner or pass it to them during intercourse.
How do you know if you have a yeast infection?
The disease usually presents the following symptoms:
itching, burning, vaginal dryness;
pain during sexual intercourse;
burning pain when urinating;
thick white discharge that appears curdled [3].
Such symptoms can also occur with other gynecological issues, including bacterial vaginosis and STDs. For a clear diagnosis, consult with your doctor.
Is it dangerous to conceive if you have a yeast infection?
Vaginal candidiasis does not directly affect conception. But sometimes the symptoms are so acute (for example, vaginal dryness or pain during sex) intercourse is so uncomfortable that a woman will rather avoid it.
Should you treat a yeast infection?
If you are planning on becoming pregnant and suspect you have a yeast infection, it is better to treat it. In itself, vaginal candidiasis does not lead to complications during pregnancy [4]; but it may increase the risk of developing other infections which, in turn, increase the risk of premature birth and miscarriage.
Is yogurt an effective treatment for a yeast infection?
There is no convincing evidence that the probiotics in yogurt or other alternative methods (ointments and gels with natural ingredients) can prevent or treat vaginal candidiasis [5]. So if you do have a yeast infection, your best bet is to treat it medically before trying to get pregnant.
