What is the reason for yellow leucorrhea with sour smell?

Discharge is a gynecological disease, generally known as abnormal leucorrhea. Female friends, do you know whether your secretions are abnormal? Whether the secretions are normal is related to your physical and mental health, so you must pay attention to it. Let’s analyze the reasons why secretions have a sour and smelly smell below, hoping it will be helpful to everyone.

Causes of sour smelling discharge

Bacterial vaginitis, also known as nonspecific vaginitis, is the most common gynecological inflammation. It is a mixed infection caused by Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, etc. Due to the imbalance of vaginal intestinal flora, that is, the decrease of Lactobacillus vulgaris, the increase of Pseudomonas aeruginosa, and the change of vaginal acidity and alkalinity, it often occurs before and after menstruation, pregnancy, emergency contraception, antibiotics, immunostimulant users, elderly women, vaginal foreign bodies/vaginal trauma, chemical drugs, etc.

The specific manifestations of bacterial vaginitis: a lot of secretions, light yellow pus, sour or fishy smell, and may develop into abdominal pain and general fatigue. During a gynecological examination, it was found that the vagina was congested and edematous, with excessive secretions. A large number of pus balls can be found through acid-fast staining examination. Adding 10% ferric chloride solution into the secretion can also release amine smell (like the smell of fertilizer).

Diseases with sour smelling discharge

1. Thin, watery discharge is a characteristic of Trichomonas vaginitis, often accompanied by severe vulvar itching or burning pain.

2. The fishy smell is thin, ranging from a small amount to a lot, with a pungent smell, which is often seen in bacterial vaginitis.

3. Thick secretions (light yellow) are slightly yellow or yellow-green, thick, and often have an odor. They are often seen in acute vaginitis, cervicitis, pelvic inflammatory disease and other diseases. In addition, infection with Treponema pallidum or foreign matter residue in the female vagina can also cause this disease.

4. If there is blood in the bloody leucorrhea, you should consider diseases such as cervical cancer, cervical cysts or vaginal tumors. Neither can eliminate some healthy diseases, such as senile vaginitis, cervical erosion, and intrauterine contraceptive ring placement.

5. A lot of foul-smelling millet soup-like secretions are continuously discharged, and if it is accompanied by a strange odor, it is generally possible for advanced cervical cancer, vaginal cancer, cervical fibroids with infection, or cervical adenocarcinoma.

6. The brown leucorrhea is very thin and has a strange smell. It is suspected to be caused by vaginitis, endometritis or intrauterine contraceptive device.

7. Milky white thick secretions, large amount of characteristics are the same as normal, but the amount is large and often wets the underwear. This type of secretion is common after the use of estrogen or when the pelvic cavity is congested. It is caused by increased secretion of the cervical gland duct and vaginal mucosa.
