Heavy and yellowish leucorrhea in women is a pathological manifestation of leucorrhea. It can be caused by various reasons, such as cervical erosion, trichomoniasis, mycotic vaginitis, gonorrhea, pelvic inflammatory disease, endometritis, etc. Women with cervical erosion have yellowish leucorrhea, mainly because the erosion gradually increases in size and damages the cervical mucosa, causing it to secrete large amounts of leucorrhea, which is yellow in color due to the presence of white blood cells or other purulent cells. Trichomoniasis and mycotic vaginitis are common factors that cause leucorrhea and yellowing, mainly because trichomoniasis irritates the vaginal wall and causes increased secretion and yellowing, while mycotic vaginitis not only causes yellowing of the leucorrhea but also gives it a tofu-like appearance. Gonorrhea is a sexually transmitted infection. The gonococcus bacteria proliferate in the cervical opening of women, resulting in a large amount of yellow purulent discharge and frequent and urgent urination. Pelvic inflammatory disease and endometritis are also inflammatory diseases caused by various pathogenic bacteria, which stimulate the cervical and vaginal walls, resulting in excessive leucorrhea and yellowing. The actual fact is that you will need to pay more attention to personal hygiene, change your underwear, keep your vulva dry and fresh, and treat your leukorrhea and yellowing in a timely manner, and eat a light diet with more green fruits and vegetables.
