Primary Causes And Risk Factors For Heavy Menstruation In Women

Causes And Risk Factors For Heavy Menstruation In Women It can be distressing when you need a new pad every hour and/or it seems unmanageable to control your flow during the menstrual period. The problem can be particularly demanding when your sleep is disturbed as heavy menstruation can demand frequent changing of pads even during the night.

Besides the discomfort, heavy menstruation can also result into anemia through excessive loss of blood from the body. With today’s diet being inadequately fortified with iron, anemia is more likely to become a cause of concern for women who experience heavy menstruation. There are certain factors which can put you at risk for heavy menstruation or cause it to happen. The following are the major ones in the category.

Causes And Risk For Heavy Menstruation


Women above 40 years of age have more chances of experiencing heavy menstruation as compared to younger women. The reason behind this possibly is the hormonal changes occurring in women’s body when they approach menopause.

With approaching menopause, ovulation reduces although the estrogen and progesterone are still made in the body. Owing to reduced periods, the lining of the womb can become very thick causing more blood than usual to flow.

Family Background And Gene

Your genes can also be responsible for heavy menstruation. If your mother had it, you are likely to have it too. In a study, it was found that identical twins (same genes) had matching periods. But the non-identical twins (different genes) did not reveal so.

Young women who begin menstruating early (at 11 or 12 years of age) generally have an irregular cycle. They may skip periods for months or even experience periods lasting for many weeks at a time.


Evidence also suggests that women who have children, particularly those having more than three children, experience more blood loss during menstruation compared to those who haven’t had any children. However, age may also a cause here as women who’ve had children (or more children) are generally older than those who have not had any.

Anatomic Problems

Structural problems including fibroids and polyps can also be the reason for heavy bleeding in women. Almost 40% of women who experience heavy menstruation have problems as fibroids and polyps.

Fibroids Or Polyps


Fibroids are non-cancerous uterine tumors which typically happen during the time when a woman is in her childbearing age. Polyps are likely to become more common with aging.

Hormonal Changes

More than half of women experience heavy menstruation owing to non-structural factors. Here, the cause is hormonal. Changes in the endocrine system, particularly estrogen, are crucial. Estrogen is responsible for several sex related outcomes in women and affect many factors including sexual development, pregnancy and periods.


Certain Medications

Certain medications can cause heavy bleeding and the most common ones are the blood thinners.  A background of blood clots may demand usage of blood thinners in women which can cause heavy bleeding as a side effect. Other medicines which can cause heavy menstruation include the birth control pills.

Miscellaneous Factors

Research suggests that smoking can cause problems with periods, such as heavy bleeding. Periods are likely to be extended and irregular in women smokers. Besides, obese women are also at risk for experiencing heavy menstruation. Anovulation and ectopic pregnancy can also lead to heavy menstruation in women.
