Endometrial Polyps

Endometrial polyps are usually non-cancerous growths that develop from the inner lining of the uterus, called the endometrium. They may cause abnormal uterine bleeding, pelvic symptoms, or fertility concerns, but some are found incidentally during a gynecological examination.

Overview

Endometrial polyps are localized overgrowths of the endometrium, the tissue that lines the inside of the uterus. They may be small and flat, or they may grow on a stalk-like base. Many endometrial polyps are benign, meaning they are not cancer, but medical assessment is important because symptoms can overlap with other gynecological conditions.

Endometrial polyps are sometimes called uterine polyps. They can occur before or after menopause and may be single or multiple. Some cause abnormal bleeding, while others are discovered during an ultrasound, fertility evaluation, or investigation of a different pelvic concern.

The presence of an endometrial polyp does not automatically mean that a person needs urgent treatment. The right approach depends on several factors, including symptoms, age, menopausal status, medical history, fertility plans, and the appearance of the polyp on imaging. A gynecologist can explain whether observation, further testing, or removal is most appropriate.

Symptoms

The most common symptom of endometrial polyps is abnormal uterine bleeding. This may include heavier or longer menstrual periods, spotting between periods, bleeding after sexual intercourse, or irregular bleeding patterns. In people who have reached menopause, any vaginal bleeding should be assessed, even if it is light or occurs only once.

Some people experience pelvic cramping, a feeling of pressure, or menstrual discomfort, although many polyps do not cause pain. Endometrial polyps may also be associated with difficulty becoming pregnant or repeated implantation problems in some fertility evaluations, especially if the polyp affects the uterine cavity.

Possible symptoms include:

• Irregular menstrual bleeding or unpredictable spotting
• Heavy or prolonged periods
• Bleeding after menopause
• Bleeding after intercourse
• Pelvic discomfort or cramping in some cases
• Infertility or concerns found during IVF assessment

Symptoms alone cannot confirm an endometrial polyp. Similar bleeding patterns may occur with fibroids, hormonal changes, endometrial thickening, infection, pregnancy-related problems, or, less commonly, pre-cancerous or cancerous changes. This is why proper diagnosis is important.

Causes & Risk Factors

Endometrial polyps develop when an area of the uterine lining grows more than expected. Hormonal influences, especially estrogen activity, are thought to play an important role. The exact reason why one person develops a polyp and another does not is often not clear.

Risk may be higher during midlife, around perimenopause, and after menopause. Other factors that may be associated with endometrial polyps include excess body weight, high blood pressure, metabolic or hormonal conditions, and use of certain hormone-modulating breast cancer treatments. A history of abnormal uterine bleeding or endometrial thickening may also lead doctors to look more closely for polyps.

Endometrial polyps are usually benign, but a small proportion may contain atypical or malignant cells. The likelihood of concerning changes is generally higher in people after menopause, especially when bleeding is present or when there are additional risk factors. Because imaging cannot always determine the exact cell type, removed tissue is commonly sent for laboratory examination.

Having risk factors does not mean that a person will definitely develop endometrial polyps, and having no obvious risk factor does not rule them out. Regular gynecological care and timely evaluation of abnormal bleeding help identify the cause and guide appropriate management.

Diagnosis

Diagnosis begins with a medical history and gynecological assessment. The doctor may ask about menstrual patterns, bleeding after menopause, pregnancy history, fertility goals, medications, past procedures, and medical conditions that may influence bleeding. A pelvic examination may be performed to look for cervical or vaginal causes of bleeding.

Transvaginal ultrasound is often the first imaging test used to evaluate the uterus and endometrium. It can show thickening of the uterine lining or a suspected polyp, although very small polyps may be difficult to see. In some cases, saline infusion sonography may be recommended; this uses sterile fluid to gently outline the uterine cavity so that small growths can be seen more clearly.

Hysteroscopy is an important diagnostic and treatment tool. During hysteroscopy, a thin camera is passed through the cervix to directly view the inside of the uterus. If a polyp is seen, it can often be removed during the same procedure, depending on the clinical situation and available facilities.

When tissue is removed, it is usually examined by a pathologist under a microscope. This histopathology result confirms whether the growth is an endometrial polyp and checks for atypical or malignant changes. Tissue confirmation is especially important in people with postmenopausal bleeding or other risk factors.

Treatment Options

Treatment for endometrial polyps is individualized. A small polyp that causes no symptoms may sometimes be monitored, especially in a premenopausal person with a low-risk profile. However, observation is not suitable for everyone, and follow-up should be arranged by a gynecology specialist.

Hysteroscopic polyp removal is a commonly used treatment when a polyp is causing symptoms, appears significant on imaging, is linked with fertility concerns, or occurs after menopause. This approach allows the doctor to see the uterine cavity and remove the polyp in a targeted way. Removed tissue is then sent for laboratory analysis.

Medication may be considered in selected cases to manage abnormal bleeding or related hormonal symptoms, but medication does not always remove the polyp itself. The role of medical treatment depends on the person’s age, bleeding pattern, general health, and reproductive plans. A specialist may also address related conditions such as endometrial thickening, anemia from heavy bleeding, or hormonal imbalance.

For people planning pregnancy or IVF, treatment decisions may include whether the polyp could affect embryo implantation or miscarriage risk. For people after menopause, the focus is often on excluding pre-cancerous or cancerous changes and treating bleeding safely. The best approach is decided by a qualified gynecologist after assessment, imaging, and discussion of risks, benefits, and preferences.

Living With / Prognosis

The outlook for most people with endometrial polyps is good, especially when the polyp is benign and symptoms are properly managed. Many people feel reassured once the cause of abnormal bleeding is identified and treated. If a polyp is removed, follow-up may be recommended to review pathology results and monitor symptoms.

Endometrial polyps can sometimes recur. Recurrence does not necessarily mean a serious condition, but new or persistent symptoms should be reassessed. Keeping a record of menstrual dates, bleeding heaviness, spotting episodes, and any pelvic symptoms can help the doctor understand changes over time.

People trying to conceive may need coordinated care between gynecology and reproductive medicine specialists. If an endometrial polyp is found during fertility evaluation, the medical team will consider its size, location, symptoms, and the timing of fertility treatment before recommending next steps.

Healthy lifestyle habits, management of chronic conditions, and regular gynecological follow-up can support overall uterine health. However, lifestyle changes alone cannot diagnose or remove an endometrial polyp, so medical assessment remains important when symptoms are present.

When to See a Doctor

A doctor should be consulted for abnormal uterine bleeding, especially if bleeding is heavy, prolonged, occurs between periods, or happens after menopause. Postmenopausal bleeding should always be evaluated because it can have several causes, and early assessment helps guide safe care.

Medical advice is also recommended for persistent pelvic discomfort, bleeding after intercourse, repeated spotting, or fertility difficulties. People undergoing IVF or other fertility treatment should tell their reproductive medicine team if they have a history of polyps or unexplained bleeding.

Urgent medical care may be needed if bleeding is very heavy, if there are symptoms such as faintness or severe weakness, or if pelvic pain is intense. These symptoms can occur for reasons other than endometrial polyps and should not be ignored.

Frequently asked questions

What are endometrial polyps?

Endometrial polyps are growths that form from the inner lining of the uterus. They are often benign, but they can cause abnormal bleeding or fertility concerns. A doctor may recommend imaging and, in some cases, removal and tissue testing.

Are endometrial polyps the same as fibroids?

No. Endometrial polyps arise from the uterine lining, while fibroids develop from the muscle layer of the uterus. Both can cause abnormal bleeding, so medical evaluation is needed to tell them apart.

Can endometrial polyps cause infertility?

Endometrial polyps may affect fertility in some people, especially if they change the shape of the uterine cavity or interfere with implantation. Not every polyp causes infertility. A fertility or gynecology specialist can assess whether removal is likely to be helpful.

Do all endometrial polyps need to be removed?

Not always. Small, symptom-free polyps in low-risk premenopausal patients may sometimes be monitored. Removal is more often considered when there is abnormal bleeding, postmenopausal bleeding, fertility concerns, suspicious imaging features, or other risk factors.

How are endometrial polyps removed?

Many endometrial polyps are removed with hysteroscopy, a procedure that allows the doctor to view the inside of the uterus and remove the growth in a targeted way. The removed tissue is usually sent to a laboratory for examination. The exact procedure and setting depend on the patient’s health and specialist assessment.

Can endometrial polyps come back after treatment?

Yes, endometrial polyps can recur in some people. New bleeding or spotting after treatment should be discussed with a doctor. Follow-up care helps confirm that symptoms have resolved and that pathology results are reassuring.

Is bleeding after menopause a sign of endometrial polyps?

Endometrial polyps are one possible cause of bleeding after menopause, but they are not the only cause. Because postmenopausal bleeding can sometimes indicate more serious changes, it should always be evaluated by a qualified gynecologist.
