Painful and Heavy Bleeding: Knowing When It's Actually Too Much

What Is Dysmenorrhoea?

Dysmenorrhoea is the medical term for very painful menstrual bleeding accompanied by intense cramping. Most women experience mild discomfort during the first day or two of their cycle as the uterus contracts to shed its lining — this is called primary dysmenorrhoea (no underlying disease).

However, when the pain grows progressively worse over the years, and when bleeding is so heavy that it keeps you awake at night or requires changing a pad every hour — this indicates secondary dysmenorrhoea. It suggests an underlying pathological cause within the pelvic organs and should never be dismissed as "just how it is for women."

When Does Heavy Bleeding Stop Being Normal?

Heavy bleeding (menorrhagia) can lead to chronic iron-deficiency anaemia and persistent fatigue. Seek specialist evaluation if you recognise these patterns:

• Blood soaks through two pads or large tampons within a few consecutive hours.
• Your period lasts longer than seven days without easing.
• You pass large blood clots the size of a coin or larger.
• You feel faint, exhausted, or noticeably pale after your period due to iron loss.

The 4 Most Common Causes of Severe, Heavy Periods

Modern medicine can pinpoint the exact causes. In our clinical experience, the following conditions are most frequently responsible:

1. Endometriosis

Endometriosis occurs when tissue similar to the uterine lining grows outside the uterus — on the bowel, fallopian tubes, ligaments, or bladder. During each menstrual cycle, this displaced tissue also swells and bleeds. Since this blood has no way to exit the body, it creates inflammation, adhesions (scar tissue), and severe cramping pain.

2. Uterine Fibroids (Myomas)

Fibroids are benign muscular growths within the uterine wall. They increase the surface area of the uterine cavity and weaken the muscle's ability to contract effectively, resulting in extremely heavy, prolonged bleeding with large clots.

3. Adenomyosis

In adenomyosis, endometrial tissue does not grow outward but instead penetrates into the muscular wall of the uterus itself. This enlarges the uterus and causes chronic deep pain with exceptionally heavy menstrual flow.

4. Endometrial Polyps

Although physically small, polyps disrupt the delicate balance of the endometrial lining. They can cause spotting between periods and cramping as the uterus attempts to mechanically expel them.

How Do We Reach an Accurate Diagnosis?

We use a high-resolution 4D ultrasound with detailed transvaginal scanning to reliably visualise the internal structures, measuring blood flow to and from the uterus — revealing hidden fibroids that conventional methods may miss.

Thyroid function testing is sometimes urgently needed, as thyroid disorders can disrupt progesterone levels and clotting factors. Swabs (HPV and bacterial panels) must be checked to rule out pelvic inflammatory disease (PID). Learn more in our guide to specialist gynaecological assessments.

Effective Treatment Options

• Hormonal therapy and contraception: Specific progesterone-based medications elegantly suppress endometrial growth, keeping flow volume and associated pain at minimal levels — a stress-free stabilisation method for the ovaries.
• Hormonal intrauterine system (Mirena): A long-term local solution (active for 5 years) that releases levonorgestrel directly into the uterus, thinning the lining and reducing bleeding by up to 95% — particularly effective for adenomyosis.
• Endoscopic surgery: When polyps or significant pathology are present, a hysteroscopy allows the surgeon to visualise and remove abnormal tissue on the same day. For larger fibroids, laparoscopy — the most precise minimally invasive technique — removes growths while keeping reproductive organs intact.

FAQ — Common Patient Concerns

At what point is menstrual pain no longer acceptable? Should I just endure it?

Any pain that causes you to miss work, disrupts your daily routine, or requires doses of painkillers beyond the recommended amount is not "normal womanhood." Chronic aggressive pelvic pain is evidence of progressive hidden inflammation — such as endometriosis — and warrants prompt clinical evaluation today, not years from now.

How long can a missed period last before it becomes a concern?

Any absence of regular monthly bleeding exceeding 35 days, or complete absence for 3 calendar months, requires diagnostic workup. It may indicate hormonal depletion linked to Polycystic Ovary Syndrome (PCOS), and investigating insulin resistance becomes a priority.

Is passing large blood clots normal?

Small clots during the heaviest hours of flow (first 20 hours) can be within normal range. However, passing solid tissue or clots larger than a coin should immediately raise suspicion of obstructing fibroids or significant hormonal dysfunction — a detailed ultrasound is essential.
