There are many reasons for increased vaginal discharge. The mechanism is that various factors cause pelvic congestion or increased estrogen in the body, which in turn causes increased secretions from glands or mucous membranes in the uterus or vagina, leading to increased vaginal discharge, which can be classified as physiological or pathological.
Physiological increased vaginal discharge is often associated with changes in estrogen in the body, while pathological increased vaginal discharge is often associated with inflammation or tumours in the reproductive tract.
