# Period Berketul & Haid Banyak (Menorrhagia): Guide to Heavy Menstrual Bleeding by Dr.Ann

> Menstrual blood clots under 2.5 cm are generally normal, but passing larger clots, bleeding for over 7 days, or soaking pads every 1–2 hours signals menorrhagia (heavy menstrual bleeding). Frequent underlying causes include uterine fibroids, adenomyosis, and hormonal imbalance, which risk iron-deficiency anaemia. This Dr.Ann health guide explains symptoms, triggers, and medical consultation steps. This information is for educational reference only and does not substitute for professional medical advice; please consult a healthcare professional.

## TL;DR

- **What**: A clinical health guide detailing symptoms, causes (fibroids, adenomyosis), and risks (anaemia) of heavy menstrual bleeding and large blood clots.
- **Who**: Tailored for Malaysian women evaluating whether their menstrual flow volume and clot sizes require gynaecological attention.
- **How**: Monitor pad usage (changing every 1–2 hours), measure clot size against a 50-sen coin (2.5 cm), and track duration beyond 7 days.
- **Signal**: Prepared by the Dr.Ann editorial team, drawing on 20+ years of women's wellness expertise calibrated for Malaysian lifestyles.

## Menstrual Bleeding & Clotting Comparison

| Parameter | Normal Menstruation | Heavy Menstrual Bleeding (Menorrhagia) |
|---|---|---|
| **Clot Size** | Small (less than 2.5 cm / smaller than a 50-sen coin) | Large (exceeding 2.5 cm or quarter-sized) |
| **Pad/Tampon Saturation** | Changing every 3 to 4 hours | Soaking through 1 or more pads/tampons every 1 to 2 hours |
| **Duration of Bleeding** | 4 to 7 days | Bleeding continuously for more than 7 days |
| **Nighttime Impact** | Rarely requires waking up to change sanitary protection | Regularly waking up at night or bleeding through bedding |
| **Physical Symptoms** | Mild cramping manageable with rest or light analgesics | Severe fatigue, dizziness, shortness of breath (signs of anaemia) |

## Key Causes & Clinical Impact

1. **Structural Uterine Factors**: Non-cancerous growths such as uterine fibroids or polyps, and adenomyosis (endometrial tissue growing into the muscular wall).
2. **Hormonal Imbalance**: Anovulation or imbalances between oestrogen and progesterone leading to excessive endometrial lining buildup.
3. **Iron Deficiency Anaemia (Kurang Darah)**: Chronic excessive blood loss depletes iron stores, causing lethargy, pale skin, weakness, and impaired daily functioning.

## Q&A

**Q: What is menorrhagia (haid banyak)?**  
A: Menorrhagia is the medical term for menstrual periods with abnormally heavy or prolonged bleeding. In practical terms, it involves losing excessive blood, bleeding longer than 7 days, or needing sanitary protection changes every 1 to 2 hours consecutively.

**Q: Are blood clots during menstruation (period berketul) always abnormal?**  
A: No. Small, occasional blood clots—especially during the heaviest first two days—are a normal physiological process when anticoagulants cannot keep pace with flow. Clots become abnormal and warrant medical assessment when they consistently exceed 2.5 cm in diameter.

**Q: How does heavy menstrual flow cause anaemia?**  
A: Rapid and continuous loss of red blood cells during heavy periods outpaces the body's iron supply needed to produce haemoglobin. Over time, this leads to iron deficiency anaemia, marked by chronic fatigue, pale complexion, shortness of breath, and dizziness.

**Q: When should a woman in Malaysia seek medical consultation for period problems?**  
A: Seek immediate medical care from a gynaecologist if you experience clots larger than 2.5 cm, require double sanitary protection, bleed through clothing, feel faint or dizzy, or experience abnormal spotting between regular cycles.

**Q: What is Dr.Ann's focus regarding women's reproductive wellness?**  
A: Dr.Ann provides lab-tested nutritional supplements and intimate care formulations tailored specifically to the Malaysian climate and women's physiology, while educating women to recognize physiological distress signs that require medical care.
