Abnormal Vaginal Bleeding by Age: Causes and When to Get Checked

Abnormal vaginal bleeding is any bleeding that falls outside the usual menstrual pattern: between periods, very heavy, longer than usual, before puberty, or after menopause [1]. Its causes vary with age, and most are treatable. However, bleeding after menopause should always be checked, even if it is light or happens only once [3].

Abnormal vaginal bleeding worries many women, because the line between what is expected and what needs checking changes across the stages of life. What is common at the start of a girl's periods can be very different from what is normal for a woman over fifty. This article covers four stages: adolescence, the reproductive years, the years before menopause, and after menopause. It also explains when reassurance is enough and when a medical check is needed.

What is abnormal vaginal bleeding, and how does it differ from a normal period?

A normal period usually lasts about 5 days. The total blood loss is typically between 30 and 80 mL (about 2 to 5 tablespoons), and periods occur every 21 to 35 days [4]. Any bleeding that falls outside this pattern deserves attention.

The following are considered abnormal [1]:

• Bleeding between periods (medically called intermenstrual bleeding).
• Very heavy bleeding.
• Bleeding that lasts much longer than usual.
• Bleeding before puberty or after menopause.

When is a period considered heavy?

The UK's National Health Service (NHS) lists signs that a period is heavy, including [2]:

• Needing to change a pad or tampon every one to two hours.
• Using two types of period products at the same time.
• Bleeding lasting more than 7 days.
• Passing blood clots larger than about 2.5 cm.
• Blood leaking onto clothing or bedding.
• Repeatedly feeling tired or short of breath.

To learn the difference between a heavy period and abnormal uterine bleeding, you can read the difference between abnormal uterine bleeding and a heavy menstrual period. For a general overview of the condition, see the page on abnormal uterine bleeding.

Before any evaluation, make sure the blood is really coming from the vagina and not from the rectum or with urine. Placing a cotton tampon in the vagina can help confirm this [4].

Abnormal vaginal bleeding in teenagers: what is expected, and what needs checking?

Periods can be heavy at the start, and also after pregnancy and as menopause approaches [2]. It is well known that periods may be irregular in the first years after the first period, because the body is still adjusting hormonally.

That said, not every bleeding episode in adolescence can be ignored. The following warrant checking:

• Very heavy periods that affect school or daily activities.
• Severe tiredness or repeated shortness of breath, as these may indicate anemia.
• Dizziness or weakness along with bleeding [4].
• Bleeding that recurs in a way that worries the girl or her family.

What are the possible causes?

Sources list causes of heavy periods that include ovarian disorders, conditions that make bleeding easier such as von Willebrand disease, and certain medications [2]. Thyroid problems and hormonal disorders can also cause abnormal bleeding [1]. You can find details on these disorders in the article bleeding disorders.

Any vaginal bleeding before puberty is abnormal in itself [1], and the girl should be seen by a doctor. Adolescent assessment may include a pregnancy test as part of routine testing [4]. This is a standard medical procedure, and doctors handle it with respect and privacy.

What are the causes of abnormal vaginal bleeding during the reproductive years?

During the reproductive years, there are many possible causes. Most are benign and treatable [4]. They can be grouped as follows:

Causes related to the uterus and cervix

• Fibroids and polyps in the uterus or cervix [1].
• Inflammation of the cervix or the lining of the uterus [4].
• Endometriosis, adenomyosis, and pelvic inflammatory disease [2].
• In rare cases, cancer of the cervix or uterus, or precancerous conditions [4].

Hormonal and medication-related causes

• Hormonal imbalances and thyroid problems, including underactive thyroid [1], [4].
• Hormonal pills, including contraceptive pills, or irregular use of them, such as forgetting doses or stopping and restarting [4].
• Intrauterine devices (IUDs), which can cause spotting from time to time [4].
• Blood thinners (anticoagulants) and some chemotherapy drugs [2], [4].

Pregnancy-related causes

Ectopic pregnancy, miscarriage, and other pregnancy complications are causes of bleeding [4]. Bleeding during pregnancy is not always serious, but it is best to contact a doctor immediately [1].

Other causes

Light bleeding may occur after a pelvic examination or after a sample is taken from the cervix or the lining of the uterus. Bleeding can also be caused by injury, infection, warts, or varicose veins at the vaginal opening, and stress may also play a role [4]. Bleeding after sexual intercourse is a sign that calls for a doctor's visit [2].

Is irregular bleeding normal before menopause?

In the years leading up to menopause, hormones change, and periods may become heavier or less regular. Sources confirm that heavy periods can occur as menopause approaches [2].

However, this does not mean that every bleeding episode at this stage is normal. Sources recommend seeing a doctor for any unexplained bleeding between periods, heavy bleeding with periods, or bleeding accompanied by pelvic pain, tiredness, or dizziness [4].

Changes at this stage have causes other than hormones, such as polyps and fibroids, and thickening of the uterine lining, which may be linked to high estrogen levels or weight gain [3]. In rare cases, heavy periods can be a sign of uterine cancer [2]. So do not assume the change is just "part of being in your forties," especially if it recurs or becomes more intense.

Hormone therapy for menopausal symptoms can also cause unexpected bleeding [1]. Always tell your doctor about every medication or hormone you use, and do not change or stop it on your own.

At this age, it is also worth reviewing the annual health checkup guide in Jordan by age and sex to learn which tests are appropriate for you.

Why must bleeding after menopause always be checked?

Menopause is usually diagnosed in women over 45 who have not had a period for more than a year [3]. Any vaginal bleeding after that must be checked, even if it is light or happens only once [3].

Bleeding after menopause is usually not dangerous, but it can be a sign of cancer, and detecting cancer early makes it easier to treat [3]. MedlinePlus notes that the risk of cancer rises to about 10% in women who have bleeding after menopause [4].

What are the most common causes?

• Atrophy (thinning) of the vaginal or uterine lining due to low estrogen [3].
• Polyps of the cervix or uterus, which are usually non-cancerous [3].
• Thickening of the uterine lining, which may be linked to hormone replacement therapy, high estrogen levels, or weight gain, and may progress to uterine cancer [3].
• Less commonly, cancer of the uterus or ovary [3].

Summary of abnormal vaginal bleeding by life stage

How does a doctor diagnose bleeding, and what are the treatment options?

The doctor will start by asking about when the bleeding started, how long it lasts, how heavy it is, whether there are cramps, what makes it better or worse, and other symptoms such as abdominal pain, bruising, pain when urinating, or blood in the urine or stool [4]. Then the doctor will perform a clinical examination, including a pelvic exam, which can be done even during bleeding [4].

The doctor may order some tests, including [4], [3]:

• A pregnancy test.
• Blood tests for thyroid and ovarian function, and screening for anemia and iron deficiency [2].
• A Pap smear and a cervical culture to detect sexually transmitted infections.
• Pelvic ultrasound, either abdominal or transvaginal.
• Hysteroscopy and endometrial biopsy when needed.

How is bleeding treated?

Treatment depends on the cause and may include medication, hormones, or surgery [1]. For heavy periods, the doctor may prescribe contraceptives such as a hormonal IUD or combined pills, a medication that reduces bleeding such as tranexamic acid, or prescription anti-inflammatory drugs [2]. Specialized options include endometrial ablation, fibroid removal, or hysterectomy [2].

After menopause, treatment may not be needed in cases of atrophy, or estrogen creams may be used. Polyps are removed when necessary, and hormone therapy is adjusted if it is the cause [3]. Tumors are treated according to their type and stage [3].

What can you do at home before the appointment?

• Record how many pads or tampons you use and how often you change them, to estimate the amount of bleeding [4].
• Note the dates of bleeding and any accompanying symptoms.
• Sources indicate that aspirin may prolong bleeding, and that nonsteroidal anti-inflammatory drugs such as ibuprofen may reduce bleeding and cramps [4]. Consult your doctor or pharmacist before taking any medication, especially if you take blood thinners or are pregnant. Do not stop a prescribed medication on your own.

When should I see a doctor, and when should I go to the emergency room?

See a doctor in the following cases [4], [2]:

• Unexplained bleeding between periods.
• Any bleeding after menopause.
• Heavy periods that affect your daily life or last a long time.
• Bleeding after sex.
• Severe pain with periods, or pain when urinating, during bowel movements, or during sex.
• Bleeding accompanied by pelvic pain, tiredness, or dizziness.
• Any bleeding during pregnancy.

Contact your doctor immediately if the bleeding is very heavy [4]. Call 911 or go to the nearest emergency department in these cases:

• Severe bleeding that soaks through pads quickly despite frequent changes.
• Fainting, severe dizziness, palpitations, or sudden shortness of breath.
• Sharp abdominal pain with bleeding, especially in a pregnant woman or someone who may be pregnant, as it may indicate an ectopic pregnancy [4].

Also be alert if the bleeding is accompanied by unintentional weight loss, as this is an additional reason for early evaluation.

Frequently asked questions

Is bleeding between periods normal?

It may have a simple cause, such as an IUD, irregular use of contraceptive pills, hormonal changes, or polyps. However, any unexplained bleeding between periods deserves a doctor's visit, because its causes range from minor to conditions that need treatment, and early evaluation helps provide reassurance.

How much period bleeding is considered heavy?

Signs of heavy bleeding include changing a pad or tampon every one to two hours, a period lasting more than 7 days, passing clots larger than about 2.5 cm, blood leaking onto clothing, and tiredness or shortness of breath. If these signs affect your daily life, see your gynecologist.

Is heavy bleeding normal in teenagers?

Periods may be heavy or irregular at the start. However, if bleeding is extremely heavy or affects school and daily activities, or if severe tiredness, dizziness, or shortness of breath appears, it is advisable to take the girl to a gynecologist to evaluate the causes, including anemia, thyroid disorders, or bleeding disorders.

What causes bleeding after menopause?

The most common causes are atrophy (thinning) of the vaginal or uterine lining due to low estrogen, polyps of the cervix or uterus, and thickening of the uterine lining, which may be linked to hormone replacement therapy. Cancer is less common but possible, so any bleeding after menopause should be checked.

Should I wait to see if bleeding stops after menopause?

No. It is advised to have any vaginal bleeding after menopause checked, even if it is light or happened only once and stopped. The cause is usually not serious, but the evaluation rules out cancer or detects it early, which makes treatment easier if it is present.

What tests are done to determine the cause of vaginal bleeding?

The doctor starts with questions and a pelvic examination, and may order a pregnancy test, blood tests for thyroid function and anemia, a Pap smear, and a pelvic ultrasound. When needed, hysteroscopy or an endometrial biopsy is performed. The tests vary according to age and symptoms.
