Endometrial Hyperplasia: A Condition Affecting the Uterine Lining

Endometrial hyperplasia is a condition where the lining of the uterus, known as the endometrium, becomes abnormally thick. This can lead to various symptoms and complications.

• Causes Heavy Menstrual Bleeding: One of the primary symptoms of endometrial hyperplasia is heavy menstrual bleeding (1).
• Types Based on Cell Changes: Doctors categorize endometrial hyperplasia into three types based on the type of cell changes in the uterine lining: Benign endometrial hyperplasia, which is further divided into simple and complex subtypes (2).
• Thickening of the Endometrium: The condition involves a thickening of the endometrium due to an increased number of cells, leading to vaginal bleeding (3).
• Risk of Cancer: In some cases, endometrial hyperplasia can lead to cancer of the uterus, particularly if left untreated or if the condition is severe (4).
• Hormonal Imbalance: The thickening of the endometrium in endometrial hyperplasia may be caused by a hormonal imbalance, leading to various symptoms and complications (5).

Types of Endometrial Hyperplasia

There are four types of endometrial hyperplasia:

1. Simple endometrial hyperplasia
2. Complex endometrial hyperplasia
3. Atypical endometrial hyperplasia
4. Adenomatous endometrial hyperplasia

Symptoms and Complications

Endometrial hyperplasia can cause various symptoms, including heavy menstrual bleeding, vaginal bleeding between periods, and pelvic pain. If left untreated or if the condition is severe, it can lead to complications such as cancer of the uterus.

Endometrial hyperplasia, a precancerous condition in which the uterine lining thickens, can manifest through various symptoms. The primary signs include:

• Abnormal menstrual bleeding: This is often characterized by heavy or prolonged menstrual periods, or bleeding between cycles [3][4].
• Heavy menstrual flow: Women with endometrial hyperplasia may experience excessively heavy menstrual flow, which can lead to anemia due to the excess bleeding [1][10].
• Bleeding after menopause: Postmenopausal bleeding is another common symptom of endometrial hyperplasia, indicating that the condition has progressed beyond the normal age range for menstruation [2][4].
• Short menstrual cycles: Women with endometrial hyperplasia may experience short menstrual cycles (less than 21 days) [3].

These symptoms can be uncomfortable and may indicate a more serious underlying issue. It's essential to consult a healthcare professional if you're experiencing any of these signs, as early detection and treatment can help prevent the progression to endometrial malignancy.

According to the American College of Obstetricians and Gynecologists, abnormal uterine bleeding is the most common symptom of endometrial hyperplasia [6]. A hysterectomy may be considered in severe cases or when hormone treatments are not effective [5].

Diagnostic Tests for Endometrial Hyperplasia

Endometrial hyperplasia, a condition characterized by abnormal growth of the endometrium, can be diagnosed through various tests. The following are some of the diagnostic tests used to diagnose endometrial hyperplasia:

• Transvaginal Ultrasound Exam: A transvaginal ultrasound exam may be done to evaluate the thickness and texture of the endometrium [1].
• Endometrial Biopsy: A tissue biopsy provides the most conclusive answers for diagnosing endometrial hyperplasia. This can be done by endometrial biopsy, dilation and curettage (D&C), or hysteroscopy [6][7].
• Hysteroscopy: Diagnostic hysteroscopy should be considered to facilitate or obtain an endometrial sample, especially where outpatient sampling fails or is nondiagnostic [4].
• Ultrasound: Ultrasound exams may also be used to evaluate the thickness and texture of the endometrium [1].
• Blood Tests: While not a direct diagnostic test for endometrial hyperplasia, blood tests may be used to rule out other conditions that may cause similar symptoms.

Types of Endometrial Hyperplasia

It is essential to differentiate between various types of EH, as this can impact treatment and management [3]. A definitive diagnosis of endometrial hyperplasia, and which type, is made by histology.

Treatment Options for Endometrial Hyperplasia

Endometrial hyperplasia, a condition characterized by excessive growth of the uterine lining, can be treated with various medications. The primary goal of treatment is to alleviate symptoms and prevent progression to cancer.

• Progestin Therapy: Progestins are hormones that help regulate the menstrual cycle. They are often used as a first-line treatment for endometrial hyperplasia, particularly in cases where there is an increased risk of uterine cancer [1]. Progestin therapy can be administered orally, via injection, or through an intrauterine device (IUD) [2].
• Hormone Therapy: In some cases, hormone therapy may be recommended to treat endometrial hyperplasia. This type of treatment involves taking hormones to regulate the menstrual cycle and prevent excessive growth of the uterine lining [4].

Other Treatment Options

While medication is often effective in treating endometrial hyperplasia, there are instances where more invasive procedures may be necessary.

• Intrauterine System (IUS): In some cases, an IUS may be recommended as a treatment option for endometrial hyperplasia. This involves inserting a small device into the uterus to release hormones that help regulate the menstrual cycle [5].
• Surgery: In rare instances, surgery may be necessary to treat endometrial hyperplasia, particularly if there is an increased risk of cancer or significant abnormal bleeding [7].

Important Considerations

It's essential to note that treatment for endometrial hyperplasia should only be initiated under the guidance of a healthcare professional. They will assess individual circumstances and recommend the most suitable course of action.

Differential Diagnosis of Endometrial Hyperplasia

Endometrial hyperplasia, a condition characterized by the thickening of the uterine lining, can be challenging to diagnose due to its similarity with other conditions. The differential diagnosis for endometrial hyperplasia includes:

• Atypical complex hyperplasia: This is one of the most common mistaken diagnoses for endometrial hyperplasia [2].
• Atypical polypoid adenomyoma: This condition can be confused with endometrial carcinoma, making differential diagnosis complicated [3].
• Endometrial intraepithelial neoplasia (EIN): EIN is a precursor to endometrial cancer and can be difficult to distinguish from endometrial hyperplasia [4].
• Normal thickening during the secretory phase: The uterine lining can thicken normally during the secretory phase, making it essential to consider this in differential diagnosis [1].
• Sessile endometrial polyp(s): These polyps may contain atypical cells and can be mistaken for endometrial hyperplasia or cancer [1].

Causes of Endometrial Hyperplasia

Endometrial hyperplasia is often caused by excess estrogen without progesterone, which can lead to the thickening of the uterine lining [6]. This condition must also be differentiated from conditions that have similar ultrasound findings, such as normal thickening during the secretory phase [7].

Diagnostic Considerations

When diagnosing endometrial hyperplasia, it is essential to consider the presence of cytologic atypia in the condition being compared. For example, the differential diagnosis with atypical hyperplasia depends on the presence of cytologic atypia in the latter condition [5]. Saline hysterosonography may be necessary to determine the extent of endometrial thickening and rule out other conditions [8].
