Gynecological inflammation does not usually cause delayed menstruation, but if the patient’s condition is more severe and affects ovarian function and the endometrium, menstrual disorders may occur, and it is unclear when gynecological inflammation causes delayed menstruation. The menstrual cycle is related to the endometrium, ovarian and endocrine functions. The endometrium is shed and repaired by hormonal stimulation. Vaginal inflammation, cervicitis and vulvodynia are the more common gynecological inflammatory diseases, and patients can show congestion and edema in the corresponding areas, which usually do not affect the menstrual cycle. If the patient’s other inflammatory diseases affect the endometrium or if endometritis occurs, it may lead to incomplete shedding or even non-shedding of the endometrium and non-bleeding, but the condition is less common. It is recommended that women pay attention to personal hygiene during gynecological inflammation, wash their underwear regularly, avoid cold food and need to standardize the treatment of inflammation under the guidance of a gynecologist.
