What causes yellow leucorrhea?

Normal women all have leucorrhea, which keeps the vagina moist at a certain level to prevent the invasion of bacteria. It is abnormal for vaginal discharge to be yellow. Generally, yellow vaginal discharge is caused by bacterial infection. When a woman has a large amount of abnormal vaginal discharge, she should check whether there is any foreign body in the vagina to see if the increase in vaginal discharge is caused by infection.

Four reasons for yellow leucorrhea

Reason 1: Yellow watery leucorrhea is mostly caused by necrosis of diseased tissue, and is common in submucosal uterine fibroids, cervical cancer, fallopian tube cancer, etc.

Reason 2: Candidal vaginitis is a common type of vaginitis, often caused by Candida albicans infection. It is more common in pregnant women and diabetic patients. Long-term use of broad-spectrum antibiotics can cause imbalance in the normal vaginal flora, which is conducive to the growth and reproduction of fungi and makes people more susceptible to this disease. Patients taking corticosteroids, immunosuppressants and autoimmune diseases are more susceptible to this disease. Patients with vitamin B6 deficiency and chronic wasting diseases are prone to yellow leucorrhea.

Young women wearing tight nylon pants can increase the humidity and temperature of the perineum, which is conducive to the growth and reproduction of mold. The main symptoms of candidal vaginitis are increased leucorrhea and vulvar itching, often accompanied by local burning sensation. Typical leucorrhea is curd-like (tofu-like) or slightly yellow flakes, has a slight odor, and adheres tightly to the vaginal mucosa.

Reason 3: Trichomonas vaginitis is the most common vaginitis, caused by infection with Trichomonas vaginalis. Trichomonas vaginalis is an anaerobic parasitic protozoan that often parasitizes the urogenital tract. In women, it mainly exists in the vagina, but also in the urethra, paraurethral glands, bladder and other parts. In men, it often parasitizes in the urethra, prostate and other parts.

Trichomonas vaginitis is transmitted indirectly, that is, through baths, tubs, bath towels, swimming pools, toilets, clothing, medical equipment, dressings, etc. The main clinical manifestations of Trichomonas vaginitis are increased vaginal discharge, itching, burning or pain in the vulva and penis. The typical vaginal discharge is yellow-green, foamy, thin and has a fishy odor. When inflammation invades the urethra, there may be symptoms of urgency and frequency of urination.

Reason 4: Senile vaginitis is more common in elderly women who have been postmenopausal for many years. After menopause, ovarian function declines, endogenous estrogen is deficient, genitals atrophy, vaginal epithelium becomes thinner, local resistance is weakened, pathogenic bacteria can easily multiply and cause inflammation.

The important symptom of senile vaginitis is increased leucorrhea, often accompanied by a feeling of heaviness in the lower abdomen and vagina and a burning sensation in the vagina. The typical leucorrhea is light yellow, watery or purulent, has a foul odor, and is often mixed with a small amount of blood.
