CAUSES OF HEAVY PERIODS/MENSTRUAL BLEEDING

Menstrual flow is the result of the complex interplay of many factors that arise from the central nervous system, the pituitary gland, the ovary, the uterine muscle, and its lining. Regulation of menstrual flow is also dependent on a normally functioning clotting system. The specific evaluation of a problem for a particular woman will often depend on the duration of the problem, the age of the woman, her specific medical history, her physical examination and her ultrasound examination. Occasionally, the cause of a particular menstrual abnormality is complex and arises from abnormalities of pituitary, adrenal and ovarian function.

The causes of various menstrual disorders can be summarized as follows:

  • Hormonal
  • Clotting Disorder
  • Anatomic
  • Medication and Supplements
  • The “Apparently” Normal Uterus

Hormonal Causes

  • Pituitary gland problems
  • Thyroid gland abnormalities
  • Adrenal gland abnormalities
  • Ovarian dysfunction

Clotting Abnormalities

Clotting abnormalities may be responsible for 5% of cases of abnormally heavy menstrual bleeding. Women with clotting abnormalities generally have a history of easy bruisability or excess bleeding from relatively minor cuts and scrapes. Additional abnormalities might include:

  • Platelet dysfunction abnormalities such as Thrombocytopenia
  • Clotting factor abnormalities such as Von Willebrand Disease

Anatomic Problems

About 25% of women with heavy menstrual periods have one of the anatomic reasons listed below. In practice, the most common anatomic reason for heavy menstrual bleeding is uterine fibroids, which account for the majority of “anatomic problems” that cause abnormally heavy menstrual bleeding. A summary of “anatomic problems” include:

  • Uterine Fibroids (these benign tumours originate from the uterine muscle)
  • Polyps (these originate from the uterine lining)
  • Adenomyosis (lining tissue of the uterus is found within the muscle of the uterus)
  • Decreased uterine contractile strength
  • Endometrial cancer
  • A uterus with a large surface area

There are several important things to remember about “anatomic problems” that cause abnormally heavy periods. First, uterine cancer accounts for less than 1% of these. Although cancer is among the causes of abnormal uterine bleeding, it is rare in women under the age of 50 and, if caught early, is a very curable disease. Second, once your health care provider has determined that you don’t have cancer, the treatment is generally one of choice rather than necessity.

Though, this may be obvious to your physician or practitioner but it bears repeating that the majority of women in their 30’s and 40’s who have periods that are heavy because of anatomic reasons may not have cancer.      

  • Fibroids: the most common benign tumour in women

The uterus contains two types of tissue—an inner lining (endometrium) that sheds each month with your period and the muscular portion (myometrium). Both of these tissue types can develop growths. When the lining tissue develops growth, they’re called polyps. When the overgrowth of muscle tissue causes tumours, they are referred to as myomas (or fibroids). Fibroids mostly produce two types of symptoms: abnormal uterine bleeding and infertility (although other symptoms occur too but less frequently).

Many women with fibroids don’t have symptoms and the majority of them can simply choose to live with these benign tumours. Fibroid can grow anywhere in the uterus. In general, the closer a fibroid is to the centre of the uterus (the inner cavity), the more troublesome they become—causing heavy menstrual bleeding and infertility (or miscarriages).

  • Endometrial Polyps – Another common cause of abnormal periods

Endometrial polyps, though not as common as fibroids, are a significant cause of heavy menstrual bleeding. In addition, they are often the cause of post-menopausal bleeding (bleeding which occurs one or more years after menopause) as well as intermenstrual bleeding (bleeding that occurs between menstrual cycles). On ultrasound they may sometimes be confused with fibroids.

What’s the difference between fibroids and polyps?

Remember that the uterus contains 2 types of tissue—muscle tissue and tissue which lines the inside of the uterine cavity. Both of these tissue types can cause benign “tumours”. Fibroids originate from muscle tissue while polyps (also called ‘endometrial polyps’) originate from lining (endometrial) tissue.

Do endometrial polyps cause cancer?

Although endometrial polyps are generally benign they can be associated with malignancy—particularly in older, postmenopausal women. The only way to know for sure is to remove them and send to a pathologist for testing. This is routinely done.

Medications & Supplements That Cause Menstrual Disorders

There are a variety of medications that can cause menstrual disorders. These include:

  • Aspirin
  • Estrogens
  • Coumadin or Heparin
  • Vitamin E
  • Ginkgo biloba
  • Nonsteroidal anti-inflammatory drugs such as ibuprofen or naproxen

The “Apparently” Normal Uterus

The vast majority of women we see with abnormal uterine bleeding have what appears to be a “normal looking” uterus—which is to say that there’s no evidence of fibroids, polyps, hyperplasia or cancer. Additionally, these women turn out to have normal thyroid functions, normal clotting abilities and no evident “hormonal” problem. So why do these women bleed heavily?

This is a complex and compelling issue. Medical logic tells us that if there’s a problem, we need to find the cause in order to treat it. In theory, that would be intellectually and scientifically rewarding but life and medicine are imperfect. It turns out that often, the diagnostic procedure may be more uncomfortable than the problem or the treatment.
