Why is the leucorrhea yellow and smelly?

For female friends who have symptoms such as yellow leucorrhea with a slight fishy smell, they must want to know the cause of the yellow leucorrhea with a slight fishy smell, so that they can know whether they have gynecological inflammation. So why does leucorrhea turn yellow and have a fishy smell? Next, this article will introduce to you the relevant content about why leucorrhea is yellow and has a fishy smell. Friends who want to know more about this knowledge can take a look.

Why is the leucorrhea yellow and has a fishy smell? If your vaginal discharge is yellow and has a fishy smell, it is likely that bacterial vaginosis is at work. Bacterial vaginosis is a disease caused by the massive multiplication of multiple pathogenic bacteria in the vagina. Bacterial vaginosis 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.

The vaginal bacteria in the vagina of adult women can break down the glycogen contained in the vaginal epithelial cells into lactic acid, keeping the vaginal secretions acidic (pH 4-5). The acidic environment is not conducive to the growth and reproduction of Gardnerella. Therefore, even if 60% of healthy women carry vaginal Gardnerella, no clinical symptoms will appear. 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.

When a patient suffers from bacterial vaginosis, Gardnerella and anaerobic bacteria are mixed in the patient's vagina, which increases 100 to 1000 times compared to the vagina of a normal healthy woman. 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, so the vagina emits a corrupt fishy smell.

Treatment for bacterial vaginosis is as follows:

1. General treatment

Keep the vulva clean and dry and avoid scratching. Do not eat spicy foods. Change your underwear frequently and wash it with warm water. Do not mix it with other clothes to avoid cross infection.

2. Drug treatment

(1) Metronidazole: It is currently considered to have reliable therapeutic effects and should be taken twice a day for 7 consecutive days.

(2) Methicillin (clomiphene): Take for 3 days.

(3) Thiamphenicol (Hydroxythiomycin): It is effective against a variety of Gram-negative and Gram-positive bacteria, and has a good therapeutic effect on the growth of anaerobic bacteria, so it can also be used.

(4) Cleansing and ampicillin can also be used. In recent years, it has been advocated that no treatment is needed for asymptomatic people.

3. Local therapy

Topical medications can be used for treatment, such as metronidazole suppositories, once a night for 7 consecutive days.

4. Treatment of comorbidities

If other pathogens are detected, use medications targeting those pathogens to avoid the abuse of antibiotics. Pay attention to the medication for systemic conditions, and provide support and immunotherapy at the same time, and pay attention to adverse drug reactions.

5. Treatment of sexual partners

Male sex partners are treated at the same time.
