Why does leucorrhea turn yellow and have a fishy smell?

Women nowadays often have some unspeakable secrets, which often puts them in an embarrassing situation. For example, some women's private parts often emit an unpleasant fishy smell. You can imagine how embarrassing it would be. Such women not only have a fishy smell in their private parts, but their leucorrhea often appears in abnormal colors such as yellow. So, what is the reason for this situation?

It is generally believed that if the color of leucorrhea is yellow and there is a fishy smell in the female private parts, it means that the woman has bacterial vaginosis. Bacterial vaginosis refers to a disease caused by the massive reproduction of multiple pathogenic bacteria in the vagina. It mainly leads to the imbalance of the vaginal ecological balance, putting the vagina in a pathological state.

The bacteria that cause bacterial vaginosis are mainly Gardnerella vaginalis. Gardnerella is anaerobic and can grow easily in the vagina. The growth temperature of Gardnerella is 25-40℃, and the optimal temperature for reproduction in the human body is 35-37℃. At pH 4.5, Gardnerella is not easy to grow, and at pH 4.0 it does not grow, which is consistent with the acidic environment in the vagina of healthy women of reproductive age.

Once the vaginal environment and acidity change, such as repeated vaginal douching, drug abuse, etc., Gardnerella and certain anaerobic bacteria will multiply in large numbers. It is reported that when suffering from bacterial vaginosis, Gardnerella and anaerobic bacteria are mixed in the patient's vagina, which increases 100 to 1000 times compared with the vagina of normal healthy women. After sexual intercourse, the alkaline semen (pH 7.2-7.5) enters the vagina, further promoting the growth and reproduction of Gardnerella and anaerobic bacteria, causing the release of a large amount of amine substances, and the vagina will emit a corrupt fishy smell.

Knowing the reason why fishy smell appears in women's private parts, you should pay attention to it in your daily life. Do not wear synthetic, non-breathable underwear, do not take medicine on your own, do not frequently use vaginal wash liquid, wash the vulva with warm water before and after sexual intercourse, etc., you can effectively avoid or reduce the fishy smell.
