What are the causes of abnormal menstruation?

Patient's question:

Irregular menstruation, ciN2

Doctor's answer:

Hello, the onset of menstrual disorders is related to mental abnormalities, exposure to cold, and improper dietary structure. Emotional stress and exposure to cold can cause pelvic blood vessels to constrict in women. Some bad habits, such as alcohol consumption, can also lead to endocrine disorders, which in turn can trigger menstrual disorders.
