Normal leucorrhea is white paste or egg white like, sticky and without fishy odor. If the leucorrhea is only slightly yellow without other symptoms, it is normal and does not require treatment. However, the cause of bacterial vaginitis and chronic cervicitis should be considered, and the cause should be diagnosed at the hospital gynecological examination and treated accordingly. Common diseases and treatment 1. Bacterial vaginitis: there may be symptoms of increased vaginal discharge with yellowing, so you should go to the hospital to check vaginal pH, amine test and clue cell test. Positive results should be treated with anti-anaerobic drugs such as metronidazole, tinidazole and clindamycin. 2. Chronic cervicitis: There may be increased leucorrhea with yellowish appearance, often accompanied by irregular menstruation, dysmenorrhea and pelvic heaviness. You should go to the hospital to perform colposcopy and cervical scraping and other examinations to diagnose the cause of the disease and then treat it symptomatically. Avoid frequent sexual intercourse and vaginal douche because vaginal douche can change the vaginal environment and cause bacteria to multiply. 2. Use toilet paper to wipe from front to back after urination and defecation to avoid retrograde infection. 3. Choose to wear cotton underwear and change them frequently, and use condoms during sexual intercourse to protect the vagina from infection.
