What causes yellow discharge?

There are various causes for yellow discharge, mainly including the following: 1. Inflammation: Conditions such as bacterial vaginosis, trichomoniasis, and cervicitis can cause changes in the color of discharge, which may be accompanied by symptoms such as odor and itching. 2. Physiological factors: In some cases, yellow discharge may be a normal physiological phenomenon. For example, leukorrhea may turn yellow after remaining in the vagina for a prolonged period due to the acidic vaginal environment. No medical concern is necessary if there are no other discomfort symptoms. 3. Lifestyle habits: Poor lifestyle habits, such as inadequate hygiene, may also lead to yellow discharge. In addition, conditions such as endometriosis and cervical cancer may also cause yellow discharge. When yellow discharge occurs, it is recommended to seek timely medical examination to determine the underlying cause and receive appropriate treatment.
