What does white discharge mean and how serious is it?

Leukorrhea is a white fluid secreted by the female vagina, primarily composed of a mixture of exudates from the vaginal mucosa and secretions from the cervical canal and endometrial glands. Its formation is closely related to estrogen activity, which is why females typically begin to experience leukorrhea after puberty. Leukorrhea can be categorized into the following two types based on severity: 1. Physiological leukorrhea: Normal leukorrhea is white, creamy or egg-white-like in appearance, slightly viscous, scanty in amount, and has no fishy or foul odor. This type of discharge has no adverse effect on women's health and represents a normal secretion of the female reproductive system. 2. Pathological leukorrhea: This may result from various factors such as hormonal imbalances, trichomonas vaginitis, bacterial vaginosis, cervicitis, and others. For example, trichomonas vaginitis may cause the discharge to become frothy and grayish-yellow or yellowish-white, accompanied by itching of the external genitalia; bacterial vaginosis may lead to grayish-white, thin discharge with a characteristic fishy odor.
