When women experience abnormal secretions, odors, or discomfort in their private areas, they may feel nervous and seek medical help. However, after treatment, they may still experience recurrent attacks, which can cause headaches for women.

In fact, this is a “signal” of dysbiosis in the vaginal microbiota of women, and the vagina sends out these “signals” to tell women that they need to pay attention to their vaginal health environment. To address this issue, women can improve their lifestyle habits while also using products such as lactic acid suppositories that can help maintain a balanced microbial community, gradually restoring the microbial environment to normal. Are there any microorganisms in the female vagina? What are the functions of these microorganisms? Why is it so important to maintain the vaginal microbiota environment?

1. Vaginal microbiota

The vagina is the most private organ on a woman’s body, with many unknown secrets. Many people believe that the vagina of women is a sterile environment, which is a misconception. There are many bacteria growing and reproducing together in the vagina, which is a relatively complex area. Under normal circumstances, various bacteria present in the vagina restrict each other and coexist harmoniously, maintaining a balanced vaginal environment, forming a protective and defensive barrier. Through orderly work and operation, women’s gynecological health is safeguarded. If the balance between various bacterial communities is broken, a series of changes will occur, and the damaged barrier will cause discomfort, sending a “signal” to women to pay attention to this issue.


There are over 30 resident bacterial communities in the vagina, the most common of which is Lactobacillus. It accounts for 90% -95% of the vaginal microbiota in healthy women and is a major contributor to maintaining a healthy vaginal microbiota environment. Lactobacillus can utilize the anaerobic environment in the vagina to decompose glycogen and synthesize lactic acid, resulting in a weakly acidic environment in women’s vagina. During the process of synthesizing glycogen, Lactobacillus can also produce antibacterial substances such as hydrogen peroxide (H2O2). [1] This helps women maintain vaginal self purification and fight against infections. When the number of lactobacilli decreases due to changes in the bacterial community environment and an increase in pH, lactic acid suppositories can regulate the bacterial community environment, thereby allowing lactobacilli to reproduce again.

2. Manifestations of vaginal microbiota imbalance

Leucorrhea is a discharge from the vagina of women, and normal vaginal discharge is usually a white paste or egg white like substance with no foul odor. When the bacterial community is imbalanced, abnormal secretion of vaginal discharge may occur, such as an increase in secretion, appearing grayish white or grayish yellow, and odor; And it may be accompanied by local dryness, itching, redness, pain, or burning sensation in the vagina. These all indicate that there is an issue with the balance of your vaginal microbiota, which can lead to inflammation, such as vaginitis, a common gynecological disease.

3. Reasons for imbalance of vaginal microbiota

(1) The use of antibiotics. In the process of antibiotics inhibiting or killing bacteria, beneficial bacteria may also be killed as harmful bacteria, and drug-resistant bacteria that have not been killed may proliferate in large numbers, changing the original bacterial species and quantity, leading to bacterial imbalance.

(2) An unhealthy lifestyle. Smoking, drinking alcohol, staying up late and other unhealthy habits can reduce women’s resistance, making it easier for foreign bacteria to invade; Excessive consumption of sweets can also affect the bacterial community environment in women’s vagina. When acidic sugars are metabolized from the urethra, they can disrupt the bacterial community environment in the vagina adjacent to the urethra, causing an imbalance in the bacterial community.

(3) Long term sitting, wearing tight pants, using pads, and other behaviors that often leave women’s private parts in a warm and humid state can lead to imbalances in the microbiota when the air cannot circulate and it is difficult to dissipate heat.

(4) After menstruation and sexual intercourse, due to the weak alkalinity of blood and sperm, it is easy to damage the weak acidic environment in the female vagina, reduce the self purification function of the vagina, and also easily cause bacterial imbalance.

4. Solutions to imbalance of vaginal microbiota

(1) Reduce the use of antibiotics, strengthen exercise, improve one’s immunity and resistance, and adjust one’s mindset.

(2) Develop good lifestyle habits, go to bed early and wake up early, have a light diet, avoid spicy and greasy foods, avoid drinking or smoking, and eat less or no sweets.

(3) Do a good job of hygiene and cleanliness, keep private areas clean, frequently change personal clothing, choose breathable underwear, and keep private areas clean and tidy.

(4) Correctly view abnormal phenomena in one’s own body and seek early detection and treatment. When feeling abnormal, you can go to the hospital to seek timely treatment from a specialist.

(5) Change sanitary napkins frequently during menstruation, and pay attention to scented sanitary napkins; When the imbalance of vaginal microbiota causes inflammation, sexual intercourse is prohibited.

(6) Some exogenous vaginal lactobacillus preparations can be used as an adjuvant therapy to help rebuild the vaginal microenvironment.

For example, Vagisan Huilan Lactic Acid Suppository is a great daily personal care product. It contains lactic acid that can quickly and persistently acidify, restore and maintain the natural pH value of the vagina, and is conducive to the growth and reproduction of lactobacilli. And it can also inhibit the growth of pathogenic bacteria, helping to form natural barriers against infection.

Vagisan Huilan originated from Germany and is a century old enterprise Dr A brand under the Wolff Group.

This product is suitable for women who experience vaginal discomfort after menstruation or sexual intercourse; Women during or after antibiotic treatment; Even pregnant mothers can use it.
