Menorrhagia (Heavy Periods)

Menorrhagia is the medical term for menstrual periods with abnormally heavy or prolonged bleeding. Although heavy menstrual bleeding is a common concern, most women don’t experience blood loss severe enough to be defined as menorrhagia.

With menorrhagia, you can’t maintain your usual activities when you have your period because you have so much blood loss and cramping. If you dread your period because you have such heavy menstrual bleeding, talk with your doctor. There are many effective treatments for menorrhagia.

Symptoms of Menorrhagia

Signs and symptoms of menorrhagia may include:

Soaking through one or more sanitary pads or tampons every hour for several consecutive hours

Needing to use double sanitary protection to control your menstrual flow

Needing to wake up to change sanitary protection during the night

Bleeding for longer than a week

Passing blood clots larger than a quarter

Symptoms of anemia, such as tiredness, fatigue or shortness of breath

When to see a doctor

Seek medical help before your next scheduled exam if you experience:

Vaginal bleeding so heavy it soaks at least one pad or tampon an hour for more than two hours

Bleeding between periods or irregular vaginal bleeding

Any vaginal bleeding after menopause

Causes of Menorrhagia

In some cases, the cause of heavy menstrual bleeding is unknown, but a number of conditions may cause menorrhagia. Common causes include:

Hormone imbalance. In a normal menstrual cycle, a balance between the hormones estrogen and progesterone regulates the buildup of the lining of the uterus (endometrium), which is shed during menstruation. If a hormone imbalance occurs, the endometrium develops in excess and eventually sheds by way of heavy menstrual bleeding.

A number of conditions can cause hormone imbalances, including polycystic ovary syndrome (PCOS), obesity, insulin resistance and thyroid problems.

Dysfunction of the ovaries. If your ovaries don’t release an egg (ovulate) during a menstrual cycle (anovulation), your body doesn’t produce the hormone progesterone, as it would during a normal menstrual cycle. This leads to hormone imbalance and may result in menorrhagia.

Uterine fibroids. These noncancerous (benign) tumors of the uterus appear during your childbearing years. Uterine fibroids may cause heavier than normal or prolonged menstrual bleeding.

Polyps. Small, benign growths on the lining of the uterus (uterine polyps) may cause heavy or prolonged menstrual bleeding.

Adenomyosis. This condition occurs when glands from the endometrium become embedded in the uterine muscle, often causing heavy bleeding and painful periods.

Intrauterine device (IUD). Menorrhagia is a well-known side effect of using a nonhormonal intrauterine device for birth control. Your doctor will help you plan for alternative management options.

Pregnancy complications. A single, heavy, late period may be due to a miscarriage. Another cause of heavy bleeding during pregnancy includes an unusual location of the placenta, such as a low-lying placenta or placenta previa.

Cancer. Uterine cancer and cervical cancer can cause excessive menstrual bleeding, especially if you are postmenopausal or have had an abnormal Pap test in the past.

Inherited bleeding disorders. Some bleeding disorders — such as von Willebrand’s disease, a condition in which an important blood-clotting factor is deficient or impaired — can cause abnormal menstrual bleeding.

Medications. Certain medications, including anti-inflammatory medications, hormonal medications such as estrogen and progestins, and anticoagulants such as warfarin (Coumadin, Jantoven) or enoxaparin (Lovenox), can contribute to heavy or prolonged menstrual bleeding.

Other medical conditions. A number of other medical conditions, including liver or kidney disease, may be associated with menorrhagia.

Risk factors

Risk factors vary with age and whether you have other medical conditions that may explain your menorrhagia. In a normal cycle, the release of an egg from the ovaries stimulates the body’s production of progesterone, the female hormone most responsible for keeping periods regular. When no egg is released, insufficient progesterone can cause heavy menstrual bleeding.

Menorrhagia in adolescent girls is typically due to anovulation. Adolescent girls are especially prone to anovulatory cycles in the first year after their first menstrual period (menarche).

Menorrhagia in older reproductive-age women is typically due to uterine pathology, including fibroids, polyps and adenomyosis. However, other problems, such as uterine cancer, bleeding disorders, medication side effects and liver or kidney disease could be contributing factors.

Complications

Excessive or prolonged menstrual bleeding can lead to other medical conditions, including:

Anemia. Menorrhagia can cause blood loss anemia by reducing the number of circulating red blood cells. The number of circulating red blood cells is measured by hemoglobin, a protein that enables red blood cells to carry oxygen to tissues.

Iron deficiency anemia occurs as your body attempts to make up for the lost red blood cells by using your iron stores to make more hemoglobin, which can then carry oxygen on red blood cells. Menorrhagia may decrease iron levels enough to increase the risk of iron deficiency anemia.

Signs and symptoms include pale skin, weakness and fatigue. Although diet plays a role in iron deficiency anemia, the problem is complicated by heavy menstrual periods.

Severe pain. Along with heavy menstrual bleeding, you might have painful menstrual cramps (dysmenorrhea). Sometimes the cramps associated with menorrhagia are severe enough to require medical evaluation.

Treatment of Menorrhagia

Specific treatment for menorrhagia is based on a number of factors, including:

Your overall health and medical history

The cause and severity of the condition

Your tolerance for specific medications, procedures or therapies

The likelihood that your periods will become less heavy soon

Your future childbearing plans

Effects of the condition on your lifestyle

Your opinion or personal preference

Medications

Medical therapy for menorrhagia may include:

Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs, such as ibuprofen (Advil, Motrin IB, others) or naproxen sodium (Aleve), help reduce menstrual blood loss. NSAIDs have the added benefit of relieving painful menstrual cramps (dysmenorrhea).

Tranexamic acid. Tranexamic acid (Lysteda) helps reduce menstrual blood loss and only needs to be taken at the time of the bleeding.

Oral contraceptives. Aside from providing birth control, oral contraceptives can help regulate menstrual cycles and reduce episodes of excessive or prolonged menstrual bleeding.

Oral progesterone. The hormone progesterone can help correct hormone imbalance and reduce menorrhagia.

Hormonal IUD (Liletta, Mirena). This intrauterine device releases a type of progestin called levonorgestrel, which makes the uterine lining thin and decreases menstrual blood flow and cramping.

If you have menorrhagia from taking hormone medication, you and your doctor may be able to treat the condition by changing or stopping your medication.

If you also have anemia due to your menorrhagia, your doctor may recommend that you take iron supplements regularly. If your iron levels are low but you’re not yet anemic, you may be started on iron supplements rather than waiting until you become anemic.
