The leucorrhea is like a paste, white in color and very thick. If there is no vulvar itching and the leucorrhea has no odor, it is not recommended to use any medication, which is normal. It may be due to the lowering of hormones in the body after ovulation, which may cause the leucorrhea to be thick and pasty. If the leucorrhea is white and itchy with local odor, it may be caused by inflammation, such as cervicitis, or vaginitis. There are several types of vaginitis, such as bacterial vaginitis, trichomoniasis and mycotic vaginitis, which can cause changes in the leucorrhea. It is necessary to perform routine examination of the leucorrhoea and also cervical examination, and to treat it reasonably according to the specific situation. If it is bacterial or trichomonas infection, it can be treated with metronidazole, mycobacterial infection with clotrimazole, and cervicitis with anti-cervicitis tablets.
