1 in 10 to 1 in 20 women in Singapore experience heavy menstrual bleeding, also known as menorrhagia. Yet many of us suffer in silence, unsure if what we’re experiencing is “normal” or something that needs medical attention.

The truth is, heavy periods that interfere with your daily life aren’t something you have to just accept. Let’s explore when your period crosses the line from heavy to concerning, and what you can do about it.

What is Considered a Normal Period?

A normal menstrual cycle typically:

• Occurs every 21-35 days (averaging 28 days)
• Involves bleeding for up to 7 days
• Results in about 30-40ml of blood loss (roughly 2-3 tablespoons)
• Requires changing pads or tampons every 3-4 hours on heavy days

While everyone’s “normal” varies slightly, these guidelines help establish a baseline for comparison.

When Does It Become Heavy Menstrual Bleeding?

Medically speaking, menorrhagia means losing more than 80ml of blood per cycle—essentially double the normal amount.

But since we don’t measure our menstrual blood with measuring cups, here are practical signs that your bleeding may be excessive.

Menorrhagia Symptoms

#1 – Volume and Duration Red Flags

Pay attention if you experience the following:

• Soaking through a pad or tampon in less than an hour, especially for several consecutive hours
• Bleeding lasting longer than 7 days
• Needing both pads and tampons simultaneously to prevent leakage
• Getting up at night to change protection, disrupting your sleep
• Frequent passing of large blood clots

#2 – Signs Indicating There’s Physical Impact

Heavy bleeding affects more than your pad budget. Watch for these signs too:

• Bleeding through to clothing or bedding despite using protection
• Cancelling plans or missing work due to heavy flow
• Avoiding light-coloured clothing during your period
• Planning activities around bathroom access

#3 – Iron-Deficiency Anaemia

When you lose too much blood regularly, your body cannot keep up with producing new red blood cells. This leads to iron-deficiency anaemia which often develops so gradually you might not notice until it’s severe.

Symptoms of early anaemia:

1. Feeling more tired than usual
2. Getting winded easily
3. Feeling dizzy when standing up

Symptoms of advanced anaemia:

1. Extreme fatigue affecting daily activities
2. Shortness of breath even at rest
3. Heart palpitations or chest discomfort
4. Noticeably pale skin, lips, and nail beds
5. Difficulty concentrating
6. Frequent headaches

Severe anaemia can lead to serious complications if you don’t get it treated by a medical professional.

Common Causes Across Life Stages

Understanding what causes heavy bleeding helps you have more informed conversations with your doctor.

Hormonal Imbalances

Most common in teenagers just starting their periods and women in their 40s approaching menopause. When oestrogen and progesterone levels are off-balance, the uterine lining can grow too thick, leading to heavier bleeding when shed.

Structural Changes in the Womb

Fibroids: Benign muscle tumours found in 25% of women. Depending on their location (especially if they’re submucous fibroids under the uterine lining), they can cause significant bleeding.

Polyps: Fleshy, non-cancerous growths in the uterine lining, becoming more common from the mid-30s onwards.

Adenomyosis: A condition where the uterine lining grows into the muscle wall, causing an enlarged, often painful uterus with heavy bleeding.

Medical Conditions and Medications

• Blood clotting disorders (including genetic conditions)
• Thyroid disease
• Liver or kidney problems
• Blood-thinning medications like warfarin
• Certain IUDs (non-hormonal types)

When Cancer is a Concern

While less common, persistent heavy or irregular bleeding can signal precancerous or cancerous conditions. This is especially important for:

1. Women with bleeding between periods
2. Any bleeding after menopause
3. Women over 40 with new bleeding patterns

Uterine cancer often causes no pain in the early stages. Don’t assume painless bleeding is harmless.

Getting the Right Diagnosis

Your First Doctor’s Visit

When you see a doctor about heavy periods, expect:

1. Detailed medical history: Be prepared to describe your bleeding patterns, any medications you take, and family history
2. Physical examination: Including pelvic exam to check your cervix and uterus
3. Ultrasound scan: To visualise your uterus and identify fibroids, polyps, or other structural issues
4. Blood tests: Full blood count for anaemia, and possibly iron studies to assess your iron stores

Additional Tests if Needed

Depending on the initial findings, your doctor might recommend:

• Endometrial biopsy: A quick clinic procedure to sample the uterine lining
• Hysteroscopy: Using a small camera to look inside your uterus
• Dilation and curettage (D&C): Primarily diagnostic to rule out cancer

Treatment Options Available in Singapore

The good news? Multiple effective treatments exist, and you don’t have to jump straight to surgery.

Medical Management

1. Iron supplements: Essential for rebuilding iron stores and treating anaemia
2. Tranexamic acid: Non-hormonal tablets that reduce bleeding by helping blood clot
3. Hormonal medications:
   1. Combined oral contraceptives
   2. Progesterone tablets or injections
   3. Mirena IUD (releases hormones directly into the uterus)
      1. It can reduce menstrual blood loss by up to 90%.

Minimally Invasive Procedures

Hysterectomy, or the removal of the uterus, is the definitive cure for heavy bleeding. It might be highly effective but it’s usually reserved for when other treatments fail or aren’t suitable. It can be performed through:

• Traditional abdominal surgery
• Vaginal approach
• Laparoscopic (keyhole) surgery

Lifestyle Management

Boost Your Iron Naturally

Include these iron-rich foods in your diet.

1. Heme iron (best absorbed) such as red meat, chicken, and fish
2. Non-heme iron such as spinach, broccoli, beans, lentils, tofu and nuts
3. Iron absorption helpers (e.g., Vitamin C-rich foods like citrus fruits, tomatoes, and bell peppers)

Avoid tea and coffee with iron-rich meals as they reduce iron absorption.

Managing Daily Life

During heavy days…

1. Use overnight pads during the day for extra protection
2. Keep spare underwear and dark pants at work
3. Consider period underwear as backup protection
4. Set phone alarms to remind you to change protection
5. Stay hydrated to help with fatigue

Debunking Common Myths

Myth 1: “I will know if I’m anaemic”

Truth: many women adapt gradually to anaemia symptoms and don’t realise how tired they’ve become until after treatment when they feel dramatically better.

Myth 2: “Heavy periods cleanse the body of toxins”

Truth: Menstruation prepares the uterus for potential pregnancy—it’s not a detox process. Heavy bleeding depletes your body’s resources without any cleansing benefit.

Myth 3: “No pain means it’s not serious”

Truth: Many serious conditions, including uterine cancer, cause painless bleeding. Any abnormal bleeding pattern deserves investigation.

When to Seek Immediate Help

Go to the emergency department if you experience:

• Soaking through a pad or tampon every hour for more than 2-3 hours
• Feeling faint, dizzy, or having chest pain
• Severe shortness of breath
• Passing clots larger than a golf ball
• Bleeding that suddenly becomes much heavier than usual

Questions to Ask Your Doctor

1. What’s likely causing my heavy bleeding?
2. Which tests do I need?
3. Will treatments affect my fertility?
4. What are the success rates for different treatments?
5. How long before I see improvement?
6. What are the side effects?
7. What happens if the first treatment doesn’t work?

Living with Menorrhagia

Practical Tips From Women Who’ve Been There

1. Use apps or calendars to document flow, duration, and symptoms.
2. Tell your employer’s HR about medical appointments if needed.
3. Keep emergency supplies everywhere (car, office, gym bag, etc.)
4. Connect with other women experiencing similar challenges.

Impact on Relationships

Heavy periods can affect intimacy and family life. Open communication with your partner about your conditions helps them understand and support you better. It’s okay to:

1. Take time off from activities when needed
2. Ask for help with household tasks on heavy days
3. Prioritise your health over social obligations

Conclusion

If you’ve been wondering whether your heavy periods are normal, trust your instincts. The very fact that you’re researching this topic suggests your bleeding may be more than just “heavy normal.”

You don’t have to plan your life around your periods, miss out on activities, or live in fear of bleeding through your clothes. Partner with a Singapore women’s clinic for proper diagnosis and treatment to see an improvement or complete resolution of your symptoms.

Take that first step. Book an appointment and start the conversation.
