In the case of women, it is mostly considered to be caused by gynecological inflammation, commonly vaginitis and cervicitis. In addition, the possibility of cervical cancer cannot be ruled out, and patients are advised to consult a doctor in time for clarification. In women, the vagina is short and straight, closer to the urethra and anus, which is prone to pathogenic bacteria infection, thus leading to vaginitis. If the treatment is not timely, the pathogenic bacteria upstream infection may lead to cervicitis. If it is a male with yellow water flowing from the lower body with odor, it may be glansitis, urethritis, etc. First, women 1, vaginitis: especially bacterial vaginosis and trichomoniasis, are prone to abnormal leucorrhea manifestations, such as yellowish, odorous, watery leucorrhea, which may be accompanied by vulvar itching and burning sensation.
