What is Endometrial Hyperplasia? Causes, Symptoms and Treatment Methods

Uterine wall thickening (endometrial hyperplasia) is a condition in which the inner layer of the uterus (endometrium) thickens more than normal. This condition, which directly affects women's reproductive health, is usually caused by hormonal imbalances and can increase the risk of uterine cancer if left untreated. Uterine wall thickening can be seen frequently, especially in women before and after menopause.

What is Uterine Wall Thickening (Endometrial Hyperplasia)?

Uterine wall thickening or medically known as endometrial hyperplasia is the abnormal thickening of the endometrium, the inner layer of the uterus. Normally, the endometrium thickens under the influence of estrogen and progesterone hormones during the menstrual cycle and is shed with menstrual bleeding. However, in some cases, especially due to excessive secretion of the estrogen hormone, this thickening can reach abnormal levels.

Normal and Abnormal Thickness Values:

Pre-Menopause: The uterine wall thickness usually varies according to the phase of the menstrual cycle, but on average it should be between 7-16 mm.
Post-Menopause: In post-menopausal women, the uterine wall should usually be 4-5 mm thick. A thickening above this value may be a sign of endometrial hyperplasia.

If left untreated, uterine wall thickening can increase the risk of uterine cancer, especially in the post-menopausal period.

Symptoms of Uterine Wall Thickening

Uterine wall thickening may not always present with obvious symptoms, but the most common symptom is abnormal uterine bleeding. Bleeding that occurs especially after menopause should be monitored carefully.

Common Symptoms:

Abnormal Bleeding: Bleeding outside of the menstrual cycle, postmenopausal bleeding or excessively long menstrual bleeding.
Menstrual Irregularities: Menstrual cycles that are too short or too long, spotting between menstrual periods.
Pelvic Pain: Pain or a feeling of pressure in the lower abdomen, especially outside of menstrual periods.
Heavy and Prolonged Bleeding: Menstrual bleeding that is heavy and lasts longer than normal.

When these symptoms are noticed, especially after menopause in women, it is important to consult a doctor.

Causes of Uterine Wall Thickening

The main cause of uterine wall thickening is hormonal imbalances and especially excess estrogen hormone. While estrogen triggers the thickening of the uterine wall, progesterone ensures that this thickening is eliminated in a balanced manner. If estrogen is secreted in excess and progesterone is not sufficient, the endometrium can thicken abnormally.

Main Causes of Uterine Wall Thickening:

Hormonal Imbalances: Imbalances between estrogen and progesterone in particular.
Obesity: Fat tissue can increase estrogen production, which can lead to thickening of the uterine wall.
Polycystic Ovary Syndrome (PCOS): Since hormone imbalances are common in women with PCOS, uterine wall thickening is more common.
Menopause: Progesterone levels drop after menopause can cause thickening of the uterine wall.
Hormonal Treatments: Estrogen treatment or birth control pills can affect hormone levels.

In light of these reasons, it is important for women at risk not to neglect regular gynecological check-ups.

Types of Uterine Wall Thickening

There are several different types of uterine wall thickening, and each type has a different risk of developing into cancer. These types are usually detected through biopsy.

Types of Uterine Wall Thickening:

Simple Hyperplasia: The endometrium is thickened, but the cells appear normal. This type has a low risk of turning into cancer.
Complex Hyperplasia: There are structural changes in the endometrium, but the cells do not turn into cancer. The risk of turning into cancer is around 3%.
Hyperplasia without Atypia: Endometrium thickening is seen without any change in cell structure. Usually less tis dangerous.
Atypic Hyperplasia: The cells are abnormal and this carries a risk of turning into cancer. The probability of turning into cancer can be up to 30%.

These types play an important role in determining the treatment plan for uterine wall thickening.

How is uterine wall thickening diagnosed?

A number of methods are used to diagnose uterine wall thickening. The first step is usually a gynecological examination based on the patient's symptoms. Various imaging and biopsy methods can then be used to assess the thickness and structure of the uterine wall.

Diagnostic Methods:

Ultrasound: Transvaginal ultrasound is the most commonly used method to measure the thickness of the uterine wall.
Endometrial Biopsy: A small tissue sample is taken from the uterine wall and examined in a laboratory.
Hysteroscopy: A small camera is used to examine the inside of the uterus and a biopsy can be performed if necessary.
Blood Tests: Blood tests can be performed to measure hormone levels and investigate other possible causes.

These tests, helps determine the type of endometrial hyperplasia and assess the risk of it turning into cancer.

Treatment Methods for Uterine Wall Thickening

Treatment for uterine wall thickening varies depending on the type of hyperplasia and the patient's general health status. Treatment is usually aimed at correcting hormonal imbalances or removing abnormal cells.

Treatment Options:

Progesterone Therapy: Progesterone medications can reduce the thickening of the endometrium by balancing the effects of estrogen.
Hormone Therapy: Hormone replacement therapy can be used during the pre- and postmenopausal periods.
Surgical Intervention: Surgical methods can be used to remove abnormal areas of the endometrium. This method is often preferred, especially in atypic hyperplasia.
Hysterectomy: In cases where the risk of developing into cancer is high, the uterus may need to be removed.

The treatment process is personalized according to the patient's general health status and the severity of hyperplasia.

Relationship Between Uterine Wall Thickening and Uterine Cancer

Uterine wall thickening, especially in the case of atypic hyperplasia, carries the risk of developing into uterine cancer. Therefore, early diagnosis and treatment are extremely important to minimize the risk of uterine cancer.

Uterine Cancer Risk Factors:

Atypic Hyperplasia: The type of hyperplasia in which abnormal cells are found carries the highest risk of developing into cancer.
Age: The risk of uterine cancer is higher in postmenopausal women.
Obesity: Excess weight increases estrogen production, increasing the risk of cancer.
Family History: Women with a family history of uterine cancer are at higher risk.

Early diagnosis, regular biopsy and follow-up The risk of uterine cancer can be significantly reduced.

Uterine Wall Thickening and Menopause

Uterine wall thickening is a condition that should be carefully monitored in postmenopausal women. Progesterone production decreases during menopause, which can lead to estrogen dominance. The endometrium, under pressure from estrogen, can thicken and cause hyperplasia.

Treatment During Menopause:

Hormone Replacement Therapy: Estrogen and progesterone therapy can be applied to maintain hormonal balance during menopause.
Regular Biopsy: When abnormal bleeding occurs after menopause, the risk of uterine cancer should be evaluated with a biopsy.

If the uterine wall thickness is more than 5 mm after menopause, a biopsy is recommended.

Uterine Wall Thickening and Fertility

Uterine wall thickening during the reproductive age can negatively affect fertility. Abnormal thickening can make it harder for a fertilized egg to implant in the uterus, which can lead to infertility.

Effects on Fertility:

Ovulation Problems: Hormonal imbalances can disrupt ovulation.
Implantation Difficulties: A thickened uterine wall can make it harder for an embryo to implant.

This condition requires appropriate treatmentcan be managed and fertility can be restored.

Ways to Prevent Uterine Wall Thickening

Regular health checks, monitoring of hormone levels and a healthy lifestyle are important to prevent uterine wall thickening. In cases where abnormal bleeding is noticed, especially in women after menopause, a doctor should be consulted immediately.

Preventive Methods:

Regular Check-ups: It is recommended to have a transvaginal ultrasound and biopsy every year after menopause.
Hormone Therapy: Especially if estrogen therapy is taken after menopause, progesterone balance should be provided.
Healthy Nutrition and Weight Control: Since obesity increases estrogen production, maintaining a healthy weight reduces the risk of uterine wall thickening.

These measures help early diagnosis and treatment of uterine wall thickening.

Side Effects of Uterine Wall Thickening

Uterine wall thickening can lead to some side effects if left untreated. These side effects usually manifest themselves with abnormal bleeding and cramps.

Possible Side Effects:

Heavy Bleeding: Excessive and irregular bleeding is the most common side effect.
Cramps: Pain and cramping sensations may occur in the pelvic area.
Anemia: Heavy bleeding can lower the body's iron levels, leading to anemia.

A healthcare professional should be consulted immediately if these symptoms occur.
