The leucorrhea symptoms of pelvic inflammatory disease patients mainly include increased amount of leucorrhea, yellowish leucorrhea, sticky leucorrhea, purulent leucorrhea, foul smell, etc. When there is inflammation in the pelvis, the inflammation stimulates the cervical glandular ducts and cervical mucosa, which increases its secretion, and the secretion is the main component of the leucorrhea, so there is an increase in leucorrhea, and the increase is more serious before and after menstruation, and the repeated stimulation of inflammation causes the leucorrhea to be mostly yellow. In acute pelvic inflammatory disease, the leucorrhea can become purulent. Due to the repeated stimulation of the inflammation, the secretion is pus-like, so the leucorrhea looks pus-like and the inflammatory stimulation leads to inflammatory changes in the leucorrhea, often accompanied by varying degrees of foul odor. Patients with pelvic inflammatory disease may experience varying degrees of lower back pain and lower abdominal swelling in addition to leukorrhea, especially during menstruation.
