Heavy Periods: When Should You Be Evaluated?

Written By Kristina Calligan

Heavy periods are common, but they are not something you have to simply "live with." Bleeding that disrupts work, school, exercise, sleep, or travel deserves attention. Heavy or prolonged bleeding can also lead to iron deficiency and anemia, leaving you tired, weak, dizzy, or short of breath.

At Arcadia Women's Wellness, the first goal is to understand what "heavy" means for you. The pattern, how it has changed, and how it affects your life all matter.

What counts as a heavy period?

You may be experiencing heavy menstrual bleeding if you:

  • Bleed for more than seven days

  • Need to change a pad or tampon in less than two hours

  • Soak through one or more pads or tampons every hour for several hours

  • Need double protection or have to change products overnight

  • Pass clots about the size of a quarter or larger

  • Have flooding or gushing that limits normal activities

  • Feel exhausted, dizzy, weak, or short of breath

Bleeding between periods, after sex, during pregnancy, or after menopause is also abnormal and should be evaluated, even if it is light.

When should you seek urgent care?

Seek urgent or emergency care when bleeding is severe

Go to urgent or emergency care if you are soaking through a pad or tampon every hour for more than two hours and also feel faint, dizzy, short of breath, have chest pain, or feel severely unwell. Heavy bleeding with a positive pregnancy test, severe one-sided pelvic pain, or fainting also needs urgent evaluation.

What can cause heavy periods?

Heavy bleeding is a symptom, not a diagnosis. Clinicians often organize causes using a system called PALM-COEIN. In simple terms, heavy periods can result from changes inside the uterus, problems with ovulation, medications, bleeding disorders, or more than one cause.

Common possibilities include:

  • Fibroids or polyps. Fibroids are noncancerous growths in the uterine muscle. Polyps grow from the uterine lining. Either can increase bleeding or cause spotting and pressure.

  • Adenomyosis. Tissue similar to the uterine lining grows into the uterine muscle, which may cause heavy, painful periods.

  • Ovulation and hormone changes. Irregular ovulation can allow the lining to build up and shed heavily. This can occur during adolescence, with PCOS or PMOS, during perimenopause, or with thyroid and metabolic conditions.

  • Pregnancy-related bleeding. Miscarriage or ectopic pregnancy can cause bleeding, so a pregnancy test is important whenever pregnancy is possible.

  • Bleeding disorders. Von Willebrand disease and other clotting conditions may cause heavy periods, especially when bleeding has been heavy since the first periods. Easy bruising, frequent nosebleeds, anemia, heavy bleeding after dental work or surgery, and family history are important clues.

  • Medications and contraception. Blood thinners, some hormonal methods, and the copper IUD can change bleeding patterns.

  • Endometrial hyperplasia or cancer. These are less common, but they are important to rule out when age, medical history, or the bleeding pattern raises concern.

  • Infection or cervical conditions. Cervical inflammation, sexually transmitted infections, and other pelvic conditions can cause bleeding between periods or after sex.

What does the workup include?

Not every patient needs every test. The evaluation is based on your age, symptoms, pregnancy possibility, medications, history, and goals.

1. A detailed conversation

Your provider may ask when the bleeding began, how long periods last, how frequently you change products, whether you pass clots, and whether there is pain or bleeding between periods. A cycle tracker or notes can help.

You may also be asked about pregnancy plans, contraception, medication changes, easy bruising, nosebleeds, and family history of bleeding problems or gynecologic cancers.

2. Physical and pelvic examination

Vitals can help identify signs of blood loss. An abdominal or pelvic examination may be recommended to look for uterine enlargement, tenderness, cervical bleeding, infection, or another source of symptoms.

3. Laboratory testing

Common first tests include a pregnancy test when appropriate and a complete blood count to look for anemia. Iron studies, including ferritin, may be ordered when iron deficiency is suspected. Depending on your history, testing may also include thyroid studies, testing for a bleeding disorder, or STI testing.

A large hormone panel is not automatically needed. Hormone levels change throughout the cycle, so tests are most useful when chosen to answer a specific question.

4. Advanced gynecologic ultrasound

Pelvic ultrasound is often the first imaging study for abnormal uterine bleeding. A combined transabdominal and transvaginal ultrasound can evaluate the uterine lining, uterine muscle, fibroids, polyps, signs of adenomyosis, the ovaries, and IUD position.

If the uterine cavity needs a closer look, a saline infusion sonogram may be recommended. Sterile fluid is used during ultrasound to outline possible polyps or fibroids inside the cavity.

5. Endometrial sampling or hysteroscopy

An endometrial biopsy collects a small sample of the uterine lining. It may be recommended based on age, persistent bleeding, ultrasound findings, treatment response, or risk factors for endometrial hyperplasia. It is commonly considered for patients age 45 and older with abnormal bleeding and for younger patients with certain risk factors or ongoing symptoms.

Hysteroscopy uses a thin camera to look inside the uterus. It may be recommended when a polyp, submucosal fibroid, or another cavity abnormality is suspected, or when bleeding continues despite an initial evaluation.

What happens after the workup?

Treatment depends on the cause, severity, medical history, and future pregnancy plans. Options may include iron replacement, nonhormonal medication, hormonal treatment, an IUD, treatment of a polyp or fibroid, endometrial ablation, or another procedure.

The Bottom Line

A period is too heavy when it affects your health or your life. You do not have to wait until you are severely anemic or unable to leave the house before asking for help. Julia Cyr, DNP and Kristina Calligan, FNP at Arcadia Women's Wellness provide individualized evaluation for heavy and abnormal bleeding.
