Most of the yellowish leucorrhea is caused by vaginitis or other gynecological diseases and can be treated with antibiotics or topical vaginal medication as prescribed by the doctor. The specific medication needs to be determined by the cause of the problem, which may be mainly vaginitis, cervicitis, endometritis, etc. However, there may not be a pathological condition, but due to hygiene and diet. 1. Vaginitis: including trichomoniasis, mycotic vaginitis, bacterial vaginosis, senile vaginitis, etc., all have varying degrees of yellowing of the leucorrhoea, and require medication according to the specific disease. Routine examination of the leucorrhoea is needed at the hospital to clarify the specific cause. For example, trichomoniasis and bacterial vaginosis mainly choose metronidazole suppositories, mycotic vaginitis requires clotrimazole or miconazole nitrate, and senile vaginitis can be treated with estrogen ointment locally. 2. Cervicitis: leucorrhoea is yellowish, sometimes with blood, accompanied by vulvar itching discomfort. In case of chlamydial infection, anti-chlamydial infection drugs such as doxycycline and azithromycin can be given; in case of Neisseria gonorrhoeae infection, cephalosporins or aminoglycosides such as dacryocin can be used. In addition, celiac suppositories or anti-uteritis tablets are also available for treatment; 3. Endometritis: The patient’s leucorrhea is usually thin and watery, pale yellow, accompanied by pain in the pelvic region, excessive menstruation, and dysmenorrhea. Clinical selection of drugs is usually based on pathogen culture, patient’s condition and drug sensitivity results, commonly used cephalosporins, metronidazole, penicillin, etc.; 4. tubal inflammation: after the appearance of tubal inflammation, patients may have symptoms of increased leucorrhea, mostly pale yellow, along with vague pain in the lower abdomen, increased menstrual flow and dysmenorrhea. Usually, drugs need to be selected according to the specific condition. Penicillin, cefuroxime, roxithromycin, etc. are available. If the symptoms persist without relief and the condition is serious, surgery can be done if necessary. In addition to the above disease factors, not paying attention to local hygiene in life, wearing tight pants, and eating too spicy and stimulating can also lead to yellowing of the leucorrhea. Pay attention to the hygiene of the perineum, wash with water, change underwear regularly, avoid wearing too tight pants and underwear, and you can usually improve the symptoms.
