Understanding Endometriosis: Causes, Symptoms, and Treatment


Overview

Endometriosis occurs when tissue similar to the uterine lining (endometrium) grows outside the uterus. It commonly involves organs like the ovaries, fallopian tubes, and the tissue lining the pelvis.

Definition

Endometriosis is a condition where endometrial glands and stroma are found outside the uterus, where they abnormally attach and grow. This displaced tissue continues to act as it normally would inside the uterus, causing pain and other symptoms.

Causes

1. Retrograde Menstruation

The most widely accepted theory is that menstrual blood flows backward through the fallopian tubes into the pelvic cavity, where endometrial cells implant and grow.

2. Coelomic Metaplasia

This theory suggests that certain cells in the pelvic lining transform into endometrial-like cells in response to specific stimuli.

3. Induction Theory

A combination of the previous theories, this posits that unidentified substances from the endometrium induce mesenchymal tissue to develop into endometrial-like tissue.

4. Immune System Dysfunction

Since retrograde menstruation happens in most women, immune system defects may explain why only some develop endometriosis.

5. Genetic Factors

Women with a close relative who has endometriosis are about seven times more likely to develop the condition. However, the exact genetic mechanisms are unclear, pointing to a multi-factorial cause involving both genes and environment.

Symptoms

1. Pelvic Pain

Chronic pelvic pain, especially during menstruation, is the most common symptom. Pain often starts before menstruation and continues throughout. Adolescents may experience severe pain from their first period.

2. Dyspareunia (Pain During Intercourse)

Painful intercourse is another frequent symptom, caused by pelvic tissue adhesion or pressure on the ovaries and other areas affected by endometriosis.

3. Infertility

While debated, endometriosis is known to lower fertility rates, especially in moderate to severe cases where the fallopian tubes are affected.

4. Other Symptoms

Symptoms such as urinary issues, gastrointestinal problems, and fatigue may arise, particularly if the endometriosis affects organs outside the pelvis, such as the bladder or intestines.

Diagnosis

1. Symptom Review

Diagnosing endometriosis begins with evaluating the symptoms, particularly pelvic pain and other related discomforts.

2. Physical Examination

A pelvic exam may reveal abnormalities like a retroverted uterus, enlarged ovaries, or tenderness in specific areas like the uterosacral ligament.

3. CA-125 Blood Test

Elevated levels of the cancer marker CA-125 can indicate endometriosis, though this test lacks specificity as CA-125 can also be elevated in other conditions.

4. Imaging

Ultrasound, MRI, and sometimes CT scans can assist in diagnosing endometriosis, though they may be limited in distinguishing endometriosis from other conditions.

5. Laparoscopy

The gold standard for diagnosing endometriosis is laparoscopy, where surgeons visually inspect and, if necessary, biopsy suspicious tissue.

Treatment Options

1. Surgical Treatment

The primary goal of surgery is to remove or destroy endometriotic lesions while preserving reproductive organs. Laparoscopy is the most common surgical method, though more invasive surgery might be needed in severe cases.

2. Hormonal Therapy

Hormonal treatments aim to reduce or stop menstruation, thereby limiting the growth of endometrial tissue. Options include:
- Oral contraceptives
- Progestins
- Gonadotropin-releasing hormone (GnRH) agonists

3. Non-Hormonal Therapies

Anti-inflammatory drugs and other medications like cytokine inhibitors may help manage pain, though they do not stop the progression of the disease.

Complications

Endometriosis can lead to complications such as pelvic adhesions, chronic pain, and fertility problems. The condition can progress, with some estimates suggesting a worsening in 30-80% of cases.

Prevention

There is no known way to prevent endometriosis. However, some studies suggest that long-term use of oral contraceptives may reduce the risk. Despite this, evidence is inconsistent, and no definitive preventive measures exist.
