Does heavy bleeding during non-menstrual periods have anything to do with drinking?

Patient's question:

No

Doctor's answer:

Ovulatory bleeding can occur due to hormonal fluctuations, resulting in bleeding a few days after the period. The characteristics are light in amount or streaky, lasting 3-7 days. Cervical erosion may also cause bleeding after intercourse, usually light in amount. Pregnancy miscarriage is another cause of irregular uterine bleeding, with variable blood volume and often accompanied by abdominal pain and lower back pain.
