Vaginal Yeast Infection: Causes, Symptoms, Diagnosis and Treatment

Experiencing a vaginal yeast infection is a relatively common condition that can be quite uncomfortable, characterized by symptoms such as persistent itching and abnormal discharge. In this article, we explain the causes of vaginal candidiasis, its symptoms, diagnosis and possible treatments.



◉ Is Vaginal Yeast Infection Contagious?

Although a vaginal yeast infection is not considered a sexually transmitted infection (STI), there is still a possibility of transmitting a yeast infection to a partner. Most doctors do not recommend having sex until the infection has cleared up.

Also, engaging in sexual activity while experiencing a yeast infection can potentially prolong the duration of the infection.

◉ 10 Causes and Risk Factors for Vaginal Yeast Infection

Vaginal yeast infection is primarily caused by the overgrowth of a fungus called Candida, specifically Candida albicans.

1. Candida overgrowth

Candida is a fungus that normally exists in the vagina along with other microorganisms. However, certain circumstances can disrupt the balance of the vaginal flora, resulting in an overgrowth of Candida.

2. Weakened immune system

Individuals with weakened immune systems, such as those with HIV/AIDS or undergoing chemotherapy, are more susceptible to vaginal mycosis

3. Hormonal changes

Fluctuations in hormonal levels, particularly estrogen, can create an environment that favors the growth of Candida. This is why vaginal mycosis is more common during pregnancy, menopause, or while taking hormonal contraceptives.

4. Antibiotic use

Antibiotics can disrupt the natural balance of microorganisms in the vagina by killing off the beneficial bacteria that help control Candida. This disruption allows an overgrowth of Candida to occur.

5. Use of Corticosteroids

Prolonged use of corticosteroid medications (such as prednisone), can lead to the development of a yeast infection or worsen an existing one..

6. Diabetes

Individuals with poorly controlled or uncontrolled diabetes tend to have elevated sugar levels in both their blood and vaginal secretions. Candida, being nourished by sugar, can thrive and grow in such environments with higher glucose levels.

7. Sexual transmission

Although uncommon, vaginal mycosis can be transmitted through sexual intercourse, particularly if one partner has an active infection. However, it is not considered a sexually transmitted infection (STI) as it can occur in individuals who have never had sexual intercourse.

8. Irritant Factors

Using overly aggressive personal hygiene products, employing abrasive cleaning methods, frequently engaging in vaginal douching can all elevate the risk of developing a fungal infection.

9. Tight Clothing

Wearing synthetic, non-breathable fabrics and tight clothing can create a warm, moist environment ideal for yeast growth.

10. Sex with multiple partners

Having multiple sexual partners might also increase the chances of coming into contact with someone who has a yeast infection.

Note: While certain factors can contribute to vaginal yeast infections, the exact cause can vary among individuals, and recurring infections might result from a combination of these factors.


◉ Signs and Symptoms

Vaginal yeast infection symptoms can vary in intensity from mild to severe. Some common signs of a vaginal yeast infection include:

Note: If you suspect a vaginal yeast infection or experience persistent symptoms, seeking medical attention for an accurate diagnosis and appropriate treatment is advisable.

◉ Diagnosis

Vaginal yeast infection can be diagnosed based on symptoms, physical examination, and laboratory tests. Most commonly, a healthcare provider may diagnose vaginal mycosis based on the following:

◉ Reviewing Medical History

Healthcare professionals inquire about your medical history, which helps in understanding potential risk factors and prior occurrences of yeast infections.

◉ Symptom Assessment

The presence of common symptoms such as itching, burning, redness, swelling, and abnormal discharge (usually thick, white, and odorless) in the vaginal area.

◉ Conducting a Gynecological Examination

A visual examination of the vagina and surrounding area to check for signs of infection, including swelling, redness, and discharge.

◉ Laboratory tests

To confirm the diagnosis, laboratory tests are employed. A vaginal swab or discharge sample is collected and sent for testing. These tests help identify the presence of yeast and confirm the infection.


◉ Treatment

The treatment for vaginal mycosis typically involves antifungal medications. These medications can be administered orally, such as fluconazole, or applied topically in the form of creams, ointments, or suppositories that contain antifungal agents like clotrimazole, miconazole, or terconazole.

In addition to medication, there are several self-care measures that can be taken to help manage and prevent vaginal yeast infection:

It is important to finish the entire course of medication prescribed by the healthcare provider, even if symptoms improve before completing the treatment.

If symptoms persist or worsen despite treatment, consulting with a healthcare provider is recommended as there could be other underlying causes.

◉ Conclusion

Yeast Vaginal Infections are common and result from Candida overgrowth. Diagnosis involves considering symptoms, history, exams, and tests. Early detection and proper management are key to maintaining vaginal health.
