If the leukorrhea is abundant, more viscous, and yellowish in color, the most common clinical cause is chronic cervical inflammation. As chronic cervical inflammation makes the glands on the surface of the cervix to secrete vigorously, the secretion will increase and the local inflammation will lead to yellowish leucorrhea, so it shows as more sticky and yellowish secretion. A gynecological examination often shows local congestion and edema of the cervix, with purulent discharge in the cervical canal. Clinically, oral metronidazole tablets, combined with broad-spectrum antibiotics, are recommended for seven consecutive days. Local medication is also recommended for the cervical area, which can be treated by vaginal insertion of diazoxide suppositories for seven consecutive days.
