What causes yellow discharge and a foul odor?

Women often have vaginal discharge, and most of the time the discharge is normal, such as leucorrhea and bleeding during menstruation. But if the discharge turns yellow and is accompanied by a noticeable odor, this is definitely an abnormal phenomenon. It is very likely that there is gynecological inflammation. The most common causes are the following.

What happens if the discharge is yellow and has a bad smell?

Yellow leucorrhea with an odor is a symptom of abnormal leucorrhea. Under normal circumstances, leucorrhea is white, translucent, egg white-like, odorless, mucous substance, therefore, leucorrhea has no obvious odor. If you find that your leucorrhea has a distinct odor and is yellow in color, it may be caused by inflammation, mainly bacterial infection. You should go to the hospital as soon as possible for routine leucorrhea examination and early treatment to avoid worsening of leucorrhea symptoms. Leucorrhea is yellow and has an odor. According to the different odors, it can be classified into:

1. Yellow leucorrhea has a fishy smell: If the leucorrhea is yellow and has a fishy smell, it is likely that you have vaginitis caused by Haemophilus vaginalis, which causes the leucorrhea to have a special fishy smell. At the same time, in addition to the fishy odor of leucorrhea, it may also be accompanied by symptoms such as vaginal burning, pain, itching, and vulva moisture.

2. Yellow leucorrhea with a fishy smell: It may also be caused by vaginitis. However, if you find that your leucorrhea has a fishy smell, it may be due to vaginitis induced by some anaerobic bacteria infection, Trichomonas infection or Haemophilus vaginalis infection, which causes the leucorrhea to often have a fishy smell.

3. The leucorrhea is yellow and has a foul odor: This type of leucorrhea odor is more serious. If the leucorrhea has a foul odor, it is often caused by a serious infection or tumor of the reproductive tract. The more common diseases include malignant tumors of the reproductive tract, severe endometritis, severe cervical erosion, etc. If an elderly woman has foul-smelling leucorrhea and it is found to be bright red in color, it is often a sign of a malignant tumor.

Women whose leucorrhea turns yellow and has an odor can usually be judged to have bacterial vaginosis. The leucorrhea of ​​women with this symptom is mostly thin, milky white with yellow. In severe cases, it may be yellow. If accompanied by a foul odor, it means that the condition is quite serious and medical attention should be sought promptly.

Especially during the menstrual period, the pH value in the vagina increases significantly. The increase in pH value leads to an increase in vaginal odor. The imbalance of pH value causes bacteria to multiply in the vagina. Because the pH value in the vagina is around 4, the environment at this time is not suitable for the growth of bacteria and mold. Once this balance is broken, the vaginal bactericidal effect is lost. Therefore, women at this time should stop sexual intercourse. Even if they have intercourse, they should keep it clean and it is best not to ejaculate inside.
