Everything You Need to Know About Vaginal Discharge: A Guide for Women

Vaginal discharge is a common concern for many women and can often lead to questions about what is normal and what might indicate a health issue.

Understanding the various aspects of vaginal discharge can help women in Bangkok make informed decisions about their reproductive health.

This article provides a detailed overview of the types, causes, and treatments of vaginal discharge, along with tips for prevention and when to seek medical advice. 

What is Vaginal Discharge?

Vaginal discharge is a fluid produced by the glands inside the vagina and cervix. This fluid plays a crucial role in maintaining vaginal health and hygiene. T

he production and characteristics of vaginal discharge are influenced by various factors, including hormonal changes, menstrual cycles, and overall health.

Understanding the nature and function of vaginal discharge can help women distinguish between normal physiological discharge and potential signs of infection or other health issues.

Functions of Vaginal Discharge

Cleaning and Lubrication

Vaginal discharge serves as a natural cleanser for the vaginal canal. It helps remove dead cells, bacteria, and other debris, keeping the vagina clean and preventing the build-up of harmful microorganisms.

This self-cleaning mechanism is vital for maintaining a healthy vaginal environment.

Protection Against Vaginal Infection

The acidic nature of vaginal discharge helps maintain a healthy balance of bacteria and yeast in the vagina.

This balance is crucial in preventing infections such as bacterial vaginosis and yeast infections, both of which can cause significant discharge changes.

The presence of beneficial bacteria, such as Lactobacillus, helps create an environment that is hostile to harmful pathogens.

Indication of Reproductive Health

Abnormal vaginal discharge can be a sign of various health issues

The characteristics of vaginal discharge can provide insights into a woman’s reproductive health.

Changes in colour, consistency, and amount of discharge can indicate different phases of the menstrual cycle, ovulation, pregnancy, or potential health issues.

For example, clear, stretchy discharge often signifies ovulation, which is the most fertile phase of the menstrual cycle.

Types of Vaginal Discharge Color

Vaginal discharge varies in colour, consistency, and amount throughout the menstrual cycle and life stages. Here are the common types:

1.      Clear and Watery, with no odour:

o   Normal During: Different phases of the menstrual cycle, especially after exercise.

o   Indication: Typically a sign of normal, healthy discharge.

2.      White and Creamy:

o   Normal During: The beginning and end of the menstrual cycle.

o   Indication: Normal discharge, unless accompanied by itching or odour, which might indicate a yeast infection.

3.      Clear and Stretchy (Egg White-Like):

o   Normal During: Ovulation.

o   Indication: Indicates fertility and the optimal time for conception.

4.      Yellow or Green:

o   Potential Indication: Infection, especially if thick, chunky, or accompanied by an unpleasant odour.

o   Common Causes: Bacterial vaginosis, sexually transmitted infections (STIs) e.g., trichomoniasis.

5.      Brown or Bloody:

o   Normal During: Menstruation or just after the period.

o   Potential Indication: Irregular bleeding, potential indication of more serious conditions if not linked to menstruation.

o   Common Causes: Irregular menstrual cycles, potential sign of cervical or uterine cancer if persistent and unrelated to menstrual periods.

6.      Grey:

o   Potential Indication: Bacterial vaginosis.

o   Common Symptoms: Accompanied by a fishy odour, especially after sex.

Causes of Abnormal Discharge

Abnormal vaginal discharge can be a sign of various health issues, and discharge changes should not be ignored. Here are some common causes:

Abnormal vaginal discharge can be a sign of various health issues

Infections possible causes:

1.      Bacterial Vaginosis: Overgrowth of bacteria normally found in the vagina. Symptoms include grey discharge with a fishy odour.

2.      Yeast Infections: Overgrowth of Candida fungus. Symptoms include thick, white, cottage cheese-like discharge accompanied by itching and burning.

3.      Sexually Transmitted Infections (STIs): Including gonorrhoea, chlamydia, and trichomoniasis, which can cause yellow, green, or frothy discharge with an unpleasant odour.

Hormonal Imbalances

1.      Menopause: Decreased oestrogen levels can lead to changes in vaginal discharge, which may include mucus consistency.

2.      Pregnancy: Increased discharge due to hormonal changes and increased blood flow to the pelvic area.

Foreign Bodies

1.      Tampons or Contraceptive Devices: Forgotten tampons or improperly placed contraceptive devices can cause discharge with an unpleasant odour and potential infection.

Allergies and Irritations

1.      Personal Care Products: Allergic reactions to soaps, lotions, or feminine hygiene products can lead to abnormal discharge.

When to Seek Medical Advice

It is important to understand when changes in vaginal discharge require medical attention. You should consult a healthcare provider if you experience:

1.      Persistent Change in Colour or Consistency: Any significant and persistent change in discharge colour, consistency, or amount.

2.      Unpleasant Odour: Discharge accompanied by a strong, foul, or fishy odour.

3.      Itching, Burning, or Irritation: Symptoms of itching, burning, swelling, or redness in the vaginal area.

4.      Pain During Urination or Intercourse: Discomfort or pain while urinating or during sexual activity.

5.      Unexplained Bleeding: Bleeding between periods, after sex, or post-menopause can sometimes be accompanied by discharge changes.

6.      Other Symptoms: Additional symptoms such as fever, abdominal pain, or pelvic discomfort.


At WellMed Clinic Bangkok, we offer comprehensive diagnostic services to identify the cause of abnormal vaginal discharge.

Our approach includes a thorough medical history, physical examination, and laboratory tests to ensure accurate diagnosis and effective treatment of any vaginal discharge changes.

Medical History and Physical Examination: The healthcare provider will review the patient’s symptoms, duration, and contributing factors such as changes in sexual activity, medications, or personal care products.

A pelvic exam is conducted to assess the vagina, cervix, and surrounding areas for signs of infection or abnormalities. A Pap smear may be performed to screen for cervical cancer and other conditions.

Laboratory Tests: A sample of the vaginal discharge is collected and analyzed under a microscope to identify bacteria, yeast, or other pathogens.

Culture or PCR tests can grow and identify specific bacteria or fungi, guiding precise treatment. Additionally, pH testing of the discharge and blood tests for STIs may be conducted to provide further diagnostic insights.

Treatment Options

Medications: Antibiotics are used for bacterial infections like bacterial vaginosis or STIs, where discharge changes can be a common symptom.

Antifungals treat yeast infections and come as creams, ointments, or oral medications. Antivirals manage viral infections.

Hormonal Therapy: Hormonal imbalances, especially during menopause or in conditions like PCOS, can be managed with hormonal therapy to regulate symptoms and reduce abnormal discharge.

Lifestyle and Home Remedies: Good hygiene practices, such as regular cleaning with mild soap and water, are essential. Avoiding irritants like scented soaps and lotions helps prevent irritation.

Proper use of contraceptives, including correct placement and timely removal of tampons and devices, is crucial to prevent infections and maintain vaginal health.

Preventing Vaginal Discharge

Prevention is key to maintaining vaginal health. Here are some tips to help prevent abnormal discharge:

Practice Good Hygiene: Regularly washing the external genital area with mild soap and water is essential.

This helps remove sweat, bacteria, and other potential irritants, which can lead to discharge changes. It is also important to wipe from front to back after using the toilet to prevent the spread of bacteria from the anal region to the vagina.

Avoid Douching: Douching can disrupt the natural balance of bacteria in the vagina, increasing the risk of infections.

The vagina has a self-cleaning mechanism, and douching can interfere with this process, leading to imbalances that result in abnormal discharge.

Wear Breathable Underwear: Choosing cotton underwear and avoiding tight-fitting clothing can help keep the vaginal area ventilated, reducing moisture buildup.

Proper ventilation is important in preventing the growth of bacteria and yeast that thrive in moist environments.

Practice Safe Sex: Using condoms during sexual activity is crucial in reducing the risk of STIs, which can cause abnormal discharge.

Open communication with sexual partners about sexual health and regular STI testing can also help in early detection and prevention.

Healthy Lifestyle: Maintaining a balanced diet, exercising regularly, and managing stress are important for supporting overall health and immune function.

A healthy lifestyle can help your body maintain its natural defenses, including a balanced vaginal microbiome, which is essential for preventing infections and abnormal discharge.
