Vaginal discharge is a natural and necessary part of the female reproductive system. However, changes in smell can sometimes be a cause for concern. A mild, slightly musky odor is often normal, but there are times when certain odors or changes in discharge can indicate an imbalance or infection.
In a recent Instagram Live session, Dr. Anjali Kumar (aka Maitriwoman), MBBS, MD – Obstetrician and Gynecologist, was left speechless when one of her followers asked, “Is there anything wrong with the slight odor in your vaginal discharge?” But first, let’s understand what causes vaginal odor.
What causes vaginal odor?
Several factors can affect the odor of vaginal discharge, including hormone levels, diet, hygiene, and even physical activity. A slight odor, especially during menstruation, is common due to fluctuating hormone levels.
The vagina also has a unique microbiome, composed primarily of Lactobacillus bacteria, which helps maintain a slightly acidic environment and protects against infections. Minor changes in odor are often caused by harmless changes in this microbiome.

Studies show that if the odor is mild and not accompanied by other symptoms, such as itching, burning, or unusual discharge color, it’s usually not a cause for concern. A study published in Science Direct suggests that the natural vaginal pH and bacterial balance causes a natural, faint odor to the discharge, which changes throughout the menstrual cycle.
The natural pH of the vagina (3.8-4.5) and the presence of beneficial Lactobacillus bacteria help maintain a healthy balance, resulting in a faint, natural odor that may vary slightly depending on hormonal changes during the menstrual cycle. This acidic environment protects against infections and promotes vaginal health.
According to Dr. Kumar, other symptoms that could indicate an infection include:
- Gray, green, or yellow discharge
- Itching or burning around the vaginal area
- Pain during urination or sexual intercourse
Possible causes of changes in vaginal odor
- Strava
- Health products
- Hormonal changes
- Sexual activity
- Infection

When should we see a doctor?
If you notice a persistent change in odor or other symptoms, consult your healthcare provider. They may suggest tests to check for infection or imbalances. Regular gynecological exams can help monitor vaginal health and ensure that any underlying conditions are addressed in a timely manner.
Bottom line
A slight odor from vaginal discharge is usually normal and can be caused by factors such as diet, hormonal changes, or fluctuating activity levels. Being aware of your body’s patterns and understanding what’s normal for you can help you recognize when something feels off. Prioritizing good hygiene, a balanced diet, and wearing breathable fabrics can promote a healthy vaginal environment and help you feel confident and comfortable in your daily life.
