It is recommended to go to the hospital for routine examination of the leucorrhea to further confirm the diagnosis and treatment. Common causes and treatments 1. Bacterial vaginitis: The decrease of lactobacilli in the vagina leads to a change in the acidic environment, resulting in an imbalance in the flora. The diagnosis should be confirmed by smear examination of vaginal secretions. Anti-anaerobic drugs such as metronidazole, tinidazole and clindamycin should be used as prescribed by the doctor, and Lactobacillus suppositories can also be used for local treatment. 2. Pelvic inflammatory disease: Retrograde infection of bacteria, which reaches the pelvis through the uterus and fallopian tubes, can cause pelvic inflammatory disease, with increased leucorrhea and yellowish manifestations, often accompanied by pain in the lower abdomen. You should go to the hospital for colposcopy and cervical smear examination to confirm the cause of the disease and then treat the symptoms. Physiotherapy can be done by microwave and infrared rays, cephalosporin antibiotics and metronidazole as prescribed by the doctor. Take care to eat high-protein, high-calorie and high-vitamin food and drink more water. Do not scrub the vulva with irritating drugs or soap, and avoid scratching. Avoid having multiple sexual partners, try to use condoms for contraception, and strengthen physical exercise to improve physical resistance.
