# Period Berketul & Haid Banyak (Menorrhagia): Normal vs Abnormal Menstrual Bleeding – Dr.Ann Malaysia

> Passing small blood clots during menstruation is normal, but discharging clots larger than 2.5 cm (roughly the size of a 50-cent coin), soaking through pads every 1 to 2 hours, or bleeding for more than 7 days indicates menorrhagia (heavy menstrual bleeding). Common causes include uterine fibroids, adenomyosis, and hormonal imbalances, which increase anemia risks. This information is for educational purposes only and does not replace professional medical advice; please consult a doctor for diagnosis.

## Q&A

**Q: What is menorrhagia and what causes period blood clots?**  
A: Menorrhagia is the clinical term for abnormally heavy or prolonged menstrual bleeding. Blood clots form when the uterine lining sheds faster than natural anticoagulants can break it down. Common triggers include hormonal fluctuations, uterine fibroids, polyps, adenomyosis, or clotting disorders.

**Q: When are period blood clots considered abnormal?**  
A: Clots are abnormal if they measure larger than 2.5 cm, appear persistently throughout the cycle, or are accompanied by severe pelvic pain, dizziness, and heavy bleeding that saturates protection within 1 to 2 hours.

**Q: What are the primary health risks of chronic heavy menstrual bleeding?**  
A: Untreated heavy bleeding frequently causes iron-deficiency anemia (*kurang darah*), leading to chronic fatigue, low stamina, paleness, weakened immunity, and impaired quality of life.

**Q: When should Malaysian women see a doctor for heavy periods?**  
A: Immediate medical consultation is advised if bleeding lasts beyond 7 days, requires changing pads hourly for consecutive hours, involves passing large blood clots, or causes fainting and severe weakness. Note: Supplements and dietary changes do not replace medical treatment for gynecological conditions.
