Symptoms, Causes, Treatment and Prevention Methods of Vaginal Yeast Infection

Vaginal yeast infection is one of the most common health problems women face throughout their lives. Although it is generally seen as a situation to be embarrassed or hidden by, it is a very common and mostly easily treatable infection. Yeast infections occurring in the vagina cause complaints such as itching, discharge, and irritation in particular. It can be quickly brought under control with accurate information and appropriate treatment.

What is a Vaginal Yeast Infection?

A vaginal yeast infection is a type of infection that occurs as a result of the overgrowth of natural yeast fungi present in the vagina. The most common microorganism causing this is Candida albicans, and this condition is medically referred to as "vulvovaginal candidiasis". Under normal conditions, the vagina has a natural balance between Lactobacillus bacteria and various yeast fungi. Lactobacillus bacteria prevent harmful microorganisms from multiplying by keeping the vaginal pH at an acidic level. When this balance is disrupted, yeast fungi multiply uncontrollably and an infection develops.

A vaginal yeast infection is not a sexually transmitted disease, but it can affect the frequency of sexual activity. This condition is seen in 75% of women at least once in their lives, and in 45% of them two or more times. It is encountered more frequently during pregnancy, in diabetes, and in cases of a weakened immune system.

What Are the Symptoms of a Vaginal Yeast Infection?

Vaginal yeast infection symptoms may vary from person to person, but the most common symptoms are:

Itching and burning sensation: An intense itching sensation in the vaginal area creates discomfort that increases especially at night. The burning sensation accompanying this itching can affect daily activities.

Changes in vaginal discharge: Normal vaginal discharge is usually clear or slightly white. Vaginal yeast discharge, on the other hand, turns into a thick white color, its consistency thickens, and it takes on an appearance similar to cottage cheese crumbs. This discharge is usually odorless or has a slightly yeast-like odor.

Pain during sexual intercourse: This condition, called dyspareunia, causes pain and discomfort during sexual intercourse due to inflammation in the vaginal area.

Burning during urination: This symptom, known as dysuria, occurs as a result of contact of the infected vaginal area with urine and is felt more prominently especially in the morning hours.

Swelling and redness in the vulva: Redness, swelling, and tenderness seen in the outer genital area are signs that the infection is spreading.

These symptoms can sometimes be confused with other vaginal infections, therefore a healthcare professional must be consulted for a definitive diagnosis.

What Causes a Vaginal Yeast Infection?

Behind the occurrence of a vaginal yeast infection lies the disruption of the natural bacteria-fungus balance in the vagina. There are various factors affecting this balance. Vaginal yeast causes can be listed as follows:

Antibiotic Use: Broad-spectrum antibiotics can destroy beneficial bacteria in the vagina as well as harmful bacteria. This situation can lead to the uncontrolled proliferation of Candida.

Hormonal Changes: The menstrual cycle, pregnancy, menopause, and the use of birth control pills alter estrogen levels and disrupt the vaginal pH balance.

Diabetes: Uncontrolled blood sugar levels increase glucose, which is the source of nutrition for yeast fungi, thereby raising the risk of infection.

Weakness of the immune system: HIV, cancer treatments, drugs used after organ transplants, and chronic diseases weaken the immune system, facilitating the development of infection.

Inadequate hygiene or excessive cleaning: Just as inadequate cleaning of the vaginal area, the use of aggressive cleansing products also disrupts the natural microflora balance.

Synthetic underwear: Nylon and synthetic fabrics retain moisture, creating a suitable environment for yeast fungi to reproduce.

Stress and nutrition: Intense stress, inadequate nutrition, and excessive sugar consumption weaken the immune system and increase the risk of infection.

Sexual Intercourse: Although it is not a sexually transmitted infection, the change in pH balance in the vaginal area after sexual intercourse can trigger yeast.

How is a Vaginal Yeast Infection Diagnosed?

A vaginal yeast infection is usually diagnosed based on the patient's complaints and a gynecological examination. The following steps are followed in the diagnostic process:

Clinical evaluation: The doctor first evaluates the patient's symptoms and medical history. They obtain information about previously experienced infections, antibiotic use, and hormonal changes.

Physical examination: The vulva and vagina area are visually examined. The presence of characteristic white discharge, redness, and swelling is evaluated.

Microscopic examination: For a definitive diagnosis, a sample can be taken from the vaginal discharge and examined under a microscope, or a culture test can be performed. Thus, the type of fungus is clarified and the appropriate medication selection is made if necessary.

pH test: The vaginal pH level is measured. Normal vaginal pH is between 3.8-4.5. In a yeast infection, this value is usually normal or slightly elevated.

Culture test: In recurrent infections or when there is no response to standard treatment, a culture test is performed to determine the specific yeast species.

Differential diagnosis: Differential diagnosis is made from bacterial vaginosis, trichomonas infection, and other sexually transmitted diseases. These diagnostic methods are rapid and usually painless. They are quite important in terms of determining the appropriate treatment.

How is Vaginal Yeast Infection Treated?

Vaginal yeast infection treatment is planned according to the severity, duration of the infection, and the general health status of the patient. Recovery is usually achieved in a short time with drug therapy. The most common treatment methods can be listed as follows:

Antifungal Vaginal Creams and Suppositories: Vaginal yeast can be easily treated with suppositories and creams. Especially vaginal creams and suppositories containing active ingredients such as clotrimazole and miconazole are effective directly in the area where the fungus is located. The duration of treatment generally ranges between 3-7 days.

Oral Antifungal Medications: Single-dose orally administered capsules containing fluconazole are preferred especially in recurrent or severe infections. They should not be used without doctor supervision.

Recurrent Vaginal Yeast Treatment: In cases of recurrent vaginal yeast, chronic vaginal yeast treatment is applied to patients experiencing 4 or more infections per year. This includes long-term antifungal treatment or probiotic support. In chronic vaginal yeast cases, it can sometimes be brought under control with alternative methods such as vaginal yeast laser therapy.

Supportive Measures: Cotton underwear should be preferred, and synthetic fabrics should be avoided. The vaginal area should not be left damp, and underwear should be changed frequently. Perfumed soaps and hygiene products should be avoided. Reducing sugary foods can help prevent the formation of vaginal yeast.

Avoiding sexual intercourse during the treatment process increases the effectiveness of the treatment and prevents reinfection. Partner treatment is generally not necessary but can be evaluated in cases of recurrent vaginal yeast.

Frequently Asked Questions

Vaginal yeast infection is seen more frequently in pregnant women, those using antibiotics, individuals with weakened immune systems, diabetes patients, and people experiencing hormonal changes. In addition, women who wear synthetic underwear, overuse hygiene products, or have habits that disrupt the vaginal flora are also at risk. Some very mild cases may resolve on their own within a short time, but in most cases, the infection may progress or become chronic if treatment is not applied. If symptoms persist for a long time or are at an annoying level, medical support must be sought. In some women, vaginal yeast infection may recur. Infections that recur four or more times a year are called "recurrent vulvovaginal candidiasis" and may require a longer-term treatment. Vaginal yeast is not a sexually transmitted disease, but sexual intercourse can trigger the symptoms of the yeast or similar symptoms may occur in the partner. Especially in recurrent cases, the partner may also need to be evaluated. Among the most commonly used medications are antifungal creams and vaginal suppositories containing active ingredients such as clotrimazole, miconazole, and econazole. In addition, orally taken tablets such as fluconazole can also be preferred. The choice of medication and duration are determined by the doctor according to the severity of the disease. Some herbal or natural methods (e.g., yogurt, probiotics) can be used as support, but the scientific effectiveness of these methods is limited and they are not sufficient on their own. For treatment, medication use under a doctor's recommendation is required first. Natural methods can be chosen in addition to treatment. Depending on the treatment, symptoms usually lessen within a few days. The duration of treatment to completely clear the infection ranges on average between 3 to 7 days. In recurrent or severe cases, this period may be prolonged. Vaginal yeast during pregnancy does not pose a serious risk, but if left untreated, it can cause discomfort in the mother and there is a risk of transmission to the baby during birth. Therefore, if vaginal yeast symptoms are noticed during pregnancy, a doctor should be consulted and appropriate treatment applied. Choosing cotton underwear, keeping the genital area dry, avoiding perfumed hygiene products, avoiding unnecessary antibiotic use, and eating a balanced diet can help prevent vaginal yeast. In addition, the use of probiotics supporting the vaginal flora can also provide a protective effect. A specialist in obstetrics and gynecology (gynecology) should be consulted for vaginal yeast complaints. Gynecologists are the people who will make the correct diagnosis and determine the most appropriate treatment plan. Contact immediately or make an appointment.
