Heavy Menstrual Bleeding

Heavy menstrual bleeding (HMB) or menorrhagia is one of the most common reasons for which women seek a Gynaecologist’s help.  There are over 355 million menstruating women in India and about 60% of them may need medical help at some time in their lives to deal with heavy periods. It is not always a cause for alarm, but in some cases, it can lead to diagnosis of underlying causes which need treatment.

Why do Women have Periods?

Imagine a life without periods – no bleeding, no pain, no sanitary napkins and no tampons freedom.  Before you get too carried away with that utopian thought, have you ever wondered why women have periods?  Well, it’s because we are special of course!  Every month the womb prepares for a possible pregnancy and when this does not happen it sheds the lining of the womb which results in a period or menses.  This usually happens once a month and a woman bleeds on an average for 5 days.  The normal cycle varies from 21 to 35 days and the bleeding can last from 2 to 7 days. So, having a regular period most often indicates that a woman is ovulating every month.  So, ladies the next time you moan about your periods remember it is your monthly reminder that you are capable of having a baby!

How do you make out if the bleeding is bad enough to seek attention?

• Do you have to change tampons or pads every hour for several consecutive hours? If you are using a menstrual cup, does the menstrual bleeding exceed 80 ml each menstruation?
• Do you have to change pads/tampons in the night?
• Do you pass large blood clots throughout your menstruation?
• Do you have to restrict physical activities during your menstruation due to heavy bleeding?
• Do you bleed longer than a week?
• Do you have symptoms of anaemia, such as tiredness or shortness of breath?
• In short, is your period disrupting your normal life every month?

Then it is high time you sought help to get back to a normal life.

We should find out what causes HMD before we can address it

Any hormone problem or condition that affects the uterus can cause heavy bleeding.

Hormone imbalances can occur due to thyroid dysfunction, polycystic ovarian syndrome (PCOS), dysfunction of the ovaries, obesity and insulin resistance.

Non-cancerous tumours of the uterus like polyps or fibroids may cause prolonged and heavy menstruation.

Sometimes the lining of the uterus can grow into the muscular wall of the uterus. The lining or the endometrium then continues to thicken, breakdown and bleed like normal during each menstrual cycle leading to heavy painful menstruation.

HMB is a known side effect of a non-hormonal intrauterine device for birth control.

In the first trimester, signs of a miscarriage can mimic a menstrual period, because there will be bleeding and clotting

Some bleeding disorders can cause abnormal menstrual bleeding.

Certain medications, Such as anticoagulants can contribute to heavy or prolonged menstrual bleeding.

Although it should not be the first thought at the sight of a heavy period, cancer does form a small possibility, especially in cases of older women.

Can it happen at any age?

Heavy bleeding during menstruation can happen at any age, but the reasons behind it may vary.

What can I expect when I see the doctor?

How is it treated?
