What is the cause of yellow-green and odorless vaginal discharge?

Many female friends know that leucorrhea is an important symbol of whether a woman is healthy. Normal leucorrhea should be colorless and odorless. Only when your body has certain diseases, the leucorrhea will change, or turn yellow-green or brown, and be accompanied by a certain fishy smell. Now let us understand what causes the yellow-green and odorless leucorrhea.

1. What is leucorrhea

Leucorrhea is a sticky white liquid that flows out of the vagina of women. It is a mixture of secretions from the Bartholin's glands, cervical glands, endometrium, exudate from the vaginal mucosa, and desquamated vaginal epithelial cells. Leucorrhea contains lactobacillus, lysozyme and antibodies, so it has the effect of inhibiting bacterial growth. During sexual intercourse, the amount of leucorrhea will increase, which will lubricate the vagina and facilitate sexual intercourse. Generally, the amount of leucorrhea increases during the middle of the menstrual period and becomes thin and transparent; after ovulation, the leucorrhea becomes thick, turbid and less in quantity. There is an increase in leucorrhea before menstruation and during pregnancy. Non-primate mammals appear during estrus.

1. Physiological leucorrhea

Physiological leucorrhea includes secretions from the labia majora and minora, Bartholin's glands, vaginal exudates and cervical glands, as well as a small amount secreted by the endometrium. It is a white, flocculent, viscous liquid, the amount and properties of which vary slightly with the menstrual cycle.

2. The role of leucorrhea

Vaginal lubricant

Due to the action of the pelvic floor muscles, the female vaginal opening is closed and the front and back walls are tightly attached. The moisture in the leucorrhea keeps the female vagina moist. This moist environment can reduce the friction between the front and back walls of the vagina and protect the vaginal walls from damage. At the same time, this moist state makes women's vagina lubricated and elastic, which is beneficial to improving the quality of sexual life.

Natural antibacterial agent

Leucorrhea is rich in glycogen. Under the action of vaginal lactobacilli, glycogen produces a large amount of lactic acid, making the female vagina acidic (PH4-5), which can inhibit the growth of various pathogenic bacteria. This natural physiological effect is called vaginal self-cleaning. These bacterial communities form a normal ecological balance. However, when the human body's immunity is low, endocrine hormones change, or external factors such as tissue damage and sexual intercourse disrupt the ecological balance of the vagina, these resident bacteria will become pathogenic bacteria, break through the vaginal barrier and cause infection.

Sperm swimming pool

Mature women must have had this experience: there are always one or two days in a month that are different from usual days. The leucorrhea is clear, transparent and elastic, like egg white. That's due to the high levels of estrogen released by the ovaries. The day with the most vaginal discharge is usually the time when estrogen in the body reaches its peak, which is the ovulation period. This change in women's leucorrhea is not redundant, but has other uses. Just like a king (ovary) who wants to marry his daughter, when the princess (egg) is about to get married, he releases water (leucorrhea) into the swimming pool (vagina), because the sperms who want to become a prince consort have no legs, and God only gives them a long tail for swimming, and they can only meet the princess by swimming.

3. Yellow-green leucorrhea

When you find that there is a lot of vaginal discharge, which is yellow-green in color and has an odor, you should first pay attention to whether it is a physiological change. If the changes in the amount and properties have exceeded the physiological range, especially if you are in menopause or postmenopause, when you are prone to tumors, you should seek medical attention as soon as possible to find the root cause so that the disease can be discovered in time and given appropriate treatment. First of all, we need to find out the cause; if the leucorrhea is yellow-green or yellow with an odor, thin and foamy, or like rice water, and grayish white, it is mostly caused by Trichomonas vaginalis. It can also be seen in chronic cervicitis, senile vaginitis, endometritis, and genital gonococcal infection.

4. The harm of abnormal leucorrhea

Increased leucorrhea If abnormal leucorrhea is not treated in time and not eradicated, serious sequelae will occur, such as pelvic inflammatory disease, endometritis and other gynecological inflammations. In severe cases, terminal illnesses such as vaginal cancer, uterine cancer, and cervical cancer may occur. Many middle-aged women who get cancer are caused by not paying attention to abnormal leucorrhea when they were young. Moreover, if there is too little leucorrhea for a long time, the vagina's self-defense function will be weakened, making women more susceptible to vaginitis. Therefore, once abnormal leucorrhea is found, it must be treated in time to avoid adverse effects on the body.

The above are all the reasons why leucorrhea is yellow-green and odorless. If you have this problem, you can refer to the content below the article to find out why your leucorrhea turns yellow-green the next morning, and check and treat it early to avoid ascending infection caused by inflammation. In addition, when female friends have abnormal leucorrhea, they must pay attention to their diet and avoid eating spicy and irritating foods. It is best not to eat cold foods.
