Heavy Periods (Menorrhagia)

You change your pad twice in one hour. Again. You start carrying spare clothes to work, just in case. You tell yourself this is simply your normal menstrual cycle — heavy menstrual flow, but nothing unusual for you.

Maybe that is true. But if you have never had it checked, you may be living with heavy periods that can be treated.

Heavy periods, also called menorrhagia, are one of the most overlooked women’s health concerns. Many women normalise heavy menstrual blood loss for years before they realise it may be linked to an underlying medical condition.

What counts as a heavy period

A heavy period is menstrual bleeding that is unusually prolonged or heavy enough to disrupt daily life. A typical menstrual cycle comes every 21 to 35 days, and menstrual flow usually lasts three to seven days.

Heavy bleeding may be a sign that something is not right if you are:

• Changing pads or tampons every hour for several hours.
• Passing large clots during your period.
• Bleeding for more than seven days.
• Experiencing pelvic pain with your periods.
• Feeling tired, breathless, or unusually pale.

If your menstrual blood loss affects work, sleep, exercise, or daily routines, it is worth getting assessed.

Why heavy bleeding happens

Heavy menstrual bleeding can happen for several reasons. In many cases, it is related to hormonal imbalance, where the lining of the uterus builds up more than usual before it sheds. This can happen with thyroid disease, PCOS, insulin resistance, weight changes, or other medical conditions that affect hormones.

Structural causes are also common. Fibroids, polyps, and adenomyosis can all increase blood flow during menstruation and cause painful or prolonged periods. Fibroids and polyps are usually benign, but depending on their size and location, they can lead to significant bleeding.

Some women have a bleeding disorder such as von Willebrand disease or a platelet problem, especially if heavy periods have been present since the first menstrual cycle. If heavy bleeding started later in life, the cause is more likely to be hormonal, structural, or medication-related.

Certain medicines and devices can also affect menstrual flow. Blood thinners, some hormonal treatments, and an intrauterine device may change the amount of bleeding, sometimes as a known side effect.

Pregnancy-related causes, including miscarriage or ectopic pregnancy, can also present with heavy bleeding and need urgent medical assessment.

When to get it checked

You do not need to wait until your symptoms become severe. If your periods are affecting your energy, work, sleep, or quality of life, it is reasonable to seek medical advice.

You should also get checked sooner if:

• Your heavy bleeding started suddenly after years of normal periods.
• You now have worsening pelvic pain.
• You have a family history of bleeding disorders or heavy periods.
• You have signs of anaemia, such as fatigue, dizziness, shortness of breath, or palpitations.
• You are bleeding between periods or after sex.

Heavy menstrual bleeding should never be dismissed just because it has been happening for a long time.

What diagnosis involves

A doctor will usually begin with your medical history and symptoms, including how long your periods last, how often you change protection, and whether there is any family history of similar bleeding problems.

In many cases, the first tests include:

• A blood test to check for anaemia.
• Tests for thyroid disease if your symptoms suggest a hormone problem.
• Blood tests for clotting issues if bleeding disorders are suspected.
• A pelvic ultrasound to look for fibroids, polyps, adenomyosis, or other structural causes.

Depending on your age and symptoms, your doctor may also recommend a Pap test, a hysteroscopy, or an endometrial biopsy. The right workup depends on your age, risk factors, and the pattern of bleeding.

Treatment for menorrhagia

Treatment for menorrhagia depends on the cause of the heavy bleeding, your age, your overall health, and whether you want to get pregnant in the future.

Common treatment options include:

• Anti-inflammatory medicine, which can reduce pain and blood loss.
• Hormonal treatment such as the pill, progesterone, or a hormonal IUD.
• Iron supplements if heavy menstrual blood loss has caused iron deficiency or anaemia.
• Procedures such as hysteroscopy if the cause needs to be diagnosed and treated directly.
• Fibroid-specific treatment such as myomectomy or uterine artery embolisation.
• Endometrial ablation or hysterectomy in selected cases.

The best treatment is the one matched to the actual cause, not just the symptom.

Which specialist you need

If you have ongoing heavy periods, a gynaecologist is usually the right specialist to see. A general practitioner can help with the first round of evaluation, but persistent heavy bleeding often needs specialist assessment.

If fibroids or adenomyosis are suspected, it helps to see a gynaecologist with experience in minimally invasive treatment. If hormonal causes seem more likely, your doctor may investigate endocrine issues or refer you when needed. If a bleeding disorder is possible, a haematologist may need to be involved as well.

Not every specialist offers the same depth of experience. The right doctor is the one who can match the diagnosis to the right investigation and treatment plan.
