Heavy Menstrual Bleeding

Heavy menstrual bleeding is very common — about 1 in 3 women seek treatment for it. Yet most wait years before getting help. Heavy menstrual bleeding is not normal. It can disrupt your life and may be a sign of a more serious health problem.

The menstrual flow is made up of blood and tissue that forms the uterine lining. The normal total amount per cycle ranges from 4 to 12 teaspoons, but it varies widely from person to person. What feels "normal" for you may actually be heavy. Your doctor considers any of the following to be signs of heavy menstrual bleeding:

Watch: Understanding Heavy Menstrual Bleeding

A short educational overview of what causes heavy periods and how they are treated

Common Causes

Many things can cause heavy menstrual bleeding. Some causes are more common in younger women; others are more common in older women. Sometimes the cause is not known.

Fibroids & Polyps

Fibroids are noncancerous growths from the muscle tissue of the uterus, most common in women ages 30–40. Polyps are another type of noncancerous growth found inside the uterus or on the cervix. Both can cause heavy menstrual bleeding.

Adenomyosis & Endometriosis

In adenomyosis, the uterine lining grows into the uterine wall. Endometriosis involves tissue growing outside the uterus. Both cause heavy, painful periods and often coexist — each requiring its own targeted treatment approach.

Problems with Ovulation

When ovulation doesn't occur for several cycles, areas of the uterine lining can become too thick, causing heavy, irregular bleeding. This is common during puberty and perimenopause, and in women with PCOS or hypothyroidism.

Bleeding Disorders

When blood doesn't clot properly, it can cause heavy menstrual bleeding. Signs include heavy periods since first menstruation, heavy bleeding after childbirth or surgery, easy bruising, gum bleeding, and frequent nosebleeds.

Medications

Some medications, such as blood thinners and aspirin, can cause heavy menstrual bleeding. The copper IUD can cause heavier bleeding, especially during the first year of use. Always inform your doctor about all medications you take.

Endometrial Causes & Cancer

Heavy menstrual bleeding can be an early sign of endometrial cancer — most often diagnosed in women past menopause. Endometrial hyperplasia (thickening of the uterine lining) can also cause abnormal bleeding and requires evaluation.

Diagnosis

When you see your doctor about heavy menstrual bleeding, you will most likely be asked about the following things to help identify the underlying cause:

Your Medical History

  • Past & present illnesses and surgeries

    Including any conditions that affect the uterus, hormones, or blood clotting

  • Pregnancy history

    Number of pregnancies, deliveries, and any complications

  • All medications

    Including prescription, over-the-counter, and supplements

  • Your birth control method

    Type, duration of use, and any recent changes

Your Menstrual Cycle

Information about your menstrual cycle is very helpful. If possible, track several menstrual cycles before your visit. Note the dates, length, and amount of flow (light, medium, heavy, or spotting) on a calendar.

Pro tip for your appointment

Use our free Heavy Period Symptom Check below — log your daily pad and tampon use and get an instant score that shows whether your bleeding is clinically heavy. Print it and bring it to your visit so your provider has objective data from day one.

Tests & Exams

You may have a physical exam, including a pelvic exam. Based on your symptoms and age, other tests may also be needed.

Lab Tests

  • Complete Blood Count (CBC)

    Checks for anemia and infection — a key first step for anyone with heavy bleeding

  • Hormone Levels

    Thyroid, FSH, estrogen, and progesterone — screens for ovulatory dysfunction

  • Bleeding Disorder Tests

    Screens for Von Willebrand disease — especially if periods have been heavy since adolescence

  • Pregnancy Test & STI Screening

    When clinically indicated based on history and symptoms

Imaging & Procedures

Ultrasound

Pelvic imaging using sound waves — 2D & 3D performed in-office at Haven OBGYN

Hysteroscopy

Thin lighted scope views inside the uterus; guides targeted biopsy

Endometrial Biopsy

Small tissue sample from the uterine lining; can be done in-office

Sonohysterography

Fluid + ultrasound reveals problems inside the uterine cavity

MRI

Detailed uterine imaging when ultrasound findings need clarification

Treatment

The goals of treatment are to relieve your symptoms and treat any underlying cause. Several factors are considered when building your treatment plan:

Your overall health & medical history The cause of your bleeding Your age Your future childbearing plans

Medications

Medications are often tried first. Some medications used also prevent pregnancy, which can be helpful if you also need a birth control method.

Combined Hormonal Contraceptives

The pill, patch, and vaginal ring contain estrogen and progestin. They can lighten menstrual flow and make periods more regular. Taken continuously, they can reduce the number of periods or stop them entirely.

Also prevents pregnancy

Progestin-Only Methods

The hormonal IUD (Mirena), implant, pills, and injection may all reduce bleeding significantly. The hormonal IUD and injection may stop bleeding completely after 1 year of use.

Also prevents pregnancy

Hormone Therapy (HT)

Helpful for heavy menstrual bleeding during perimenopause, and also treats other symptoms such as hot flashes, night sweats, and vaginal dryness. Requires an individualized discussion of benefits and risks based on your history.

GnRH Agonists

Stop the menstrual cycle and reduce the size of fibroids. Used only for short periods (less than 6 months). Their effect on fibroids is temporary — fibroids return to their original size once stopped. Often used as a bridge to surgery.

Short-term use only

Tranexamic Acid

A prescription tablet taken each month at the start of the menstrual period. Reduces heavy menstrual bleeding by helping blood clot more effectively. Does not affect hormones or fertility and does not prevent pregnancy.

NSAIDs (e.g. Ibuprofen)

Nonsteroidal anti-inflammatory drugs may help control heavy bleeding by reducing prostaglandins, and also relieve menstrual cramps. Many types are available over the counter, including ibuprofen and naproxen.

Surgery

If medication does not reduce your bleeding, a surgical procedure may be recommended. The right type depends on your condition, your age, and whether you are planning a future pregnancy.

Hysteroscopy

Can be used to remove fibroids or polyps and stop bleeding caused by these growths in some cases. A thin, lighted scope is inserted through the cervix — no incisions, outpatient procedure.

View surgical procedures →

Myomectomy MIGS

Surgery to remove fibroids without removing the uterus. Dr. Mishra performs minimally invasive laparoscopic and robotic myomectomy, which allows faster recovery than open surgery.

Preserves fertility Learn about MIGS →

Endometrial Ablation

Destroys the lining of the uterus to stop or greatly reduce bleeding. Pregnancy is not likely after ablation, but if it does occur, the risks of serious complications are significantly increased. Appropriate only for women who have completed childbearing.

Childbearing must be complete

Hysterectomy

Surgical removal of the uterus. Used to treat fibroids, adenomyosis, or endometrial cancer when other types of treatment have failed or are not an option. After hysterectomy, periods stop permanently and pregnancy is no longer possible.

Uterine Artery Embolization (UAE)

Used to treat fibroids by blocking the blood vessels that allow them to grow. Most women resume regular menstrual periods shortly after. Periods do not return for about 4 in 10 women over 50 who have UAE.

Treatment is never one-size-fits-all. Whether you need medical management, a minimally invasive procedure, or surgery depends entirely on your diagnosis, your symptoms, and what matters most to you.

Dr. Mishra's Approach

A diagnosis first, then a treatment plan

"Heavy bleeding is never just 'your normal.' When a patient comes to me with heavy periods, my first goal is to understand why — not hand over a prescription and hope it helps. We start with a thorough history, physical exam, and targeted imaging. Evaluation at Haven OBGYN typically includes in-office pelvic ultrasound (2D and 3D when indicated), blood work to assess for anemia and hormonal causes, and when appropriate, sonohysterography or in-office hysteroscopy. Treatment ranges from medical management to minimally invasive surgery — always guided by your diagnosis, reproductive goals, and what matters most to you."

Clinical Utility of This Tool

  • A score ≥ 100 is the validated clinical threshold for heavy menstrual bleeding — bring your chart to your appointment.
  • Turns your experience into objective data Dr. Mishra can use to guide diagnosis and treatment right away.

Important Limitations

  • Measures volume only, not cause — a score below 100 does not rule out fibroids, polyps, or other pathology.
  • Not validated for cups or discs. Scores are estimates — fill in during your cycle for best accuracy.

Frequently Asked Questions

Common questions about heavy and abnormal bleeding, answered by Dr. Nikita Mishra

Schedule a routine visit

  • Cycles becoming progressively heavier
  • Periods lasting 7 or more days
  • Clots the size of a quarter or larger
  • Bleeding that limits your daily activities

Be seen soon (within a week)

  • New or unexplained bleeding between periods
  • Any postmenopausal bleeding
  • Symptoms of anemia: fatigue, breathlessness, rapid heartbeat

Urgent — ER or call 911

  • Soaking a pad every hour for 2+ consecutive hours AND feeling dizzy or faint
  • Heavy bleeding during pregnancy
  • Suspected significant blood loss with rapid heartbeat

Clinically, heavy menstrual bleeding is defined as total blood loss exceeding 80 mL per cycle — roughly equivalent to a PBAC score of more than 100. The normal total amount ranges from about 4 to 12 teaspoons per cycle. More practically, it means soaking through a pad or tampon every hour for several consecutive hours, passing clots larger than a quarter, needing to double up on protection, or bleeding through at night. If your period is affecting your daily life, work, or sleep, it warrants evaluation — regardless of whether it meets any technical threshold.

Yes — iron-deficiency anemia is a common and often unrecognized consequence of chronic heavy menstrual bleeding. Symptoms include fatigue, shortness of breath with exertion, rapid heartbeat, difficulty concentrating, cold hands and feet, and pallor. Many women normalize these symptoms for years without realizing their period is the cause. A simple blood count and iron studies can confirm anemia. The correct long-term approach is to treat the underlying cause of heavy bleeding — not to supplement iron indefinitely.

The vast majority of heavy or abnormal bleeding is caused by benign (non-cancerous) conditions — fibroids, polyps, adenomyosis, hormonal imbalance, or bleeding disorders. However, endometrial cancer can present this way, and your doctor may recommend endometrial biopsy in women over 45 with new or changed bleeding patterns, or in younger women with risk factors such as obesity, PCOS, or a family history. Evaluation — not reassurance without workup — is always the appropriate first step.

Several effective medical options exist: the hormonal IUD (Mirena) is one of the most effective, reducing bleeding by 80–90% in many patients; combined hormonal contraceptives (pill, patch, ring) lighten and regularize flow; progestin-only methods (implant, injection) may stop bleeding altogether; tranexamic acid, taken during the period, reduces bleeding volume without hormones; and NSAIDs reduce prostaglandin-driven bleeding and cramps. The right choice depends on whether you want contraception, whether you are planning pregnancy, and the specific underlying cause.

Endometrial ablation is a minimally invasive procedure that destroys the uterine lining to stop or greatly reduce bleeding. It is appropriate for women who have completed childbearing. Pregnancy after ablation carries serious, life-threatening risks — effective contraception is required afterward. Ablation stops or significantly reduces bleeding in approximately 80–90% of patients. It should be considered only after medication or other therapies have not worked, and a thorough evaluation is needed to confirm candidacy.

Track your current or next period using the PBAC Scoring Tool above. For each day, enter the number of pads and tampons used at each saturation level, count any clots (small = grape-size, large = strawberry-size), and check the flooding box if gushing affected your daily activities. The tool calculates your score automatically. A score above 100 confirms clinically heavy menstrual bleeding. Print or screenshot the completed chart and bring it to your appointment — it gives your doctor objective, standardized data to guide your evaluation, and often significantly shortens the diagnostic process.
