Endometriosis is a medical condition where tissue similar to the lining inside the uterus, known as endometrium, starts growing outside the uterus, causing pain and sometimes even leading to fertility issues. This article will delve deeper into the topic of endometriosis by identifying its symptoms, causes, and available treatment options to manage the condition.
What Are the Symptoms of Endometriosis?
Common signs and symptoms of endometriosis include:
-
Pelvic Pain: Pelvic pain is a common symptom of endometriosis, often characterised by persistent or intermittent discomfort that worsens during menstruation. This pain can range from mild to severe.
-
Menstrual Irregularities: Heavy menstrual bleeding (menorrhagia) or bleeding between periods (spotting) are common in those with endometriosis. In serious cases, this may lead to anaemia and fatigue.
-
Pain During Intercourse: Some people with endometriosis experience deep pain during or after sexual intercourse. This is because the abnormal tissue growths can sometimes irritate the pelvic nerves and also cause inflammation and scarring.
-
Infertility: Endometriosis associated with an increased risk of difficulty becoming pregnant and is a common cause of infertility. Scar tissue and inflammation can obstruct reproductive pathways, making conceiving more challenging.
-
Painful Bowel Movements or Urination: Endometrial tissue can sometimes affect the intestines and bladder, leading to pain during bowel movements or urination, especially during menstrual periods.
-
Fatigue: Chronic pain and heavy menstruation contribute to feelings of exhaustion and low energy levels.
-
Nausea and Digestive Issues: Some individuals may experience gastrointestinal symptoms like nausea, bloating, diarrhoea, or constipation, particularly during their menstrual cycle.
What Causes Endometriosis?
The exact cause of endometriosis remains unclear, but several factors are believed to contribute to its development. Here are some potential causes:
-
Genetic Predisposition: Research suggests that endometriosis can run in families, indicating a genetic component.
-
Immune System Dysfunction: A compromised immune system may fail to recognise and destroy endometrial-like tissue growing outside the uterus, contributing to the progression of endometriosis.
Risk Factors for Endometriosis
Several factors can increase the risk of developing endometriosis. Here are some of the most common risk factors:
-
Family History: Having a close relative, such as a mother or sister with endometriosis increases the likelihood of developing the condition.
-
Early Menstruation: Starting menstruation at an early age (before age 11) is associated with a higher risk of endometriosis.
-
Short Menstrual Cycles: Menstrual cycles shorter than 27 days can increase the chances of experiencing endometriosis.
-
Heavy Menstrual Periods: Experiencing heavy menstrual bleeding (menorrhagia) that lasts more than seven days can be a risk factor.
-
Never Given Birth: Women who have never had children may be at greater risk for endometriosis.
-
High Oestrogen Levels: Elevated oestrogen levels in the body, whether naturally occurring or due to external sources, can increase the risk of endometriosis.
-
Low Body Mass Index (BMI): Women with a low BMI may have an increased risk of endometriosis.
What Are the Types of Endometriosis?
Endometriosis can be categorised into different types based on the location and nature of the endometrial-like tissue growth. Here are the primary types:
-
Superficial Peritoneal Lesion: This is the most common type of endometriosis, characterised by lesions on the surface of the peritoneum, the lining of the abdominal cavity. These lesions are usually small and superficial but can cause significant pain and inflammation.
-
Endometrioma or Endometriotic Cyst: Sometimes called "chocolate cysts," these are fluid-filled cysts that develop within the ovaries. They are filled with old, dark blood and can interfere with ovarian function, potentially affecting fertility and causing severe pelvic pain.
-
Deeply Infiltrating Endometriosis (DIE): This type involves endometrial-like tissue that grows more than 5 millimetres deep into the tissues and organs in the pelvic region, such as the bladder, bowel, or ligaments of the uterus.
How Is Endometriosis Diagnosed?
Diagnosing endometriosis involves the following:
-
Pelvic Exam: During a pelvic exam, your gynaecologist will check whether applying pressure to certain areas around the uterus is painful. The presence of hard lumps in the area may also be a sign to look out for.
-
Ultrasound: A transvaginal ultrasound (where the device is inserted into the vagina) or an abdominal ultrasound can help identify cysts associated with endometriosis.
-
Magnetic Resonance Imaging (MRI): MRI scans can identify the location and size of endometrial implants and is particularly useful for mapping deep infiltrating endometriosis (DIE).
-
Laparoscopy: Under general anaesthesia, a surgeon uses a laparoscope through a small abdominal incision to inspect and possibly biopsy endometrial lesions, providing an accurate diagnosis and assessment of the disease.
What Are the Stages of Endometriosis?
Endometriosis is classified into four stages. These stages help in understanding the severity of the condition and planning appropriate treatment.
-
Stage I: This stage is characterised by small lesions and shallow implants on the ovaries or peritoneum. There may be minimal to no scar tissue (adhesions), and the symptoms can be less severe, making this stage often harder to diagnose.
-
Stage II: In this stage, there are more lesions than in Stage I, but they remain relatively superficial. Mild adhesions may start to form, and the implants are slightly deeper, causing moderate pain and discomfort.
-
Stage III: This stage involves numerous deep implants and small cysts on one or both ovaries, known as endometriomas. There are also thick adhesions present, which can cause significant pain and possibly impact fertility.
-
Stage IV: The most advanced stage of endometriosis, characterised by many deep implants, large endometriomas on one or both ovaries and extensive adhesions. This stage can severely affect pelvic organs, leading to chronic pain and significant fertility issues.
Treatment Options for Endometriosis
Treating endometriosis involves a combination of approaches tailored to the individual's symptoms and severity of the condition. These include:
-
Oral Medications: Pain relief is commonly achieved through nonsteroidal anti-inflammatory drugs (NSAIDs). These medications help manage pain and reduce inflammation but do not address the underlying endometrial growths.
-
Hormonal Therapy: Hormonal treatments aim to suppress menstruation, potentially slowing endometrial tissue growth and alleviating symptoms. Options include:
-
Birth Control Pills: Combined oral contraceptives that contain oestrogen and progestin can regulate hormone levels, reducing menstrual bleeding and pain.
-
Gonadotropin-releasing hormone (GnRH) Agonists: These drugs induce a temporary menopause-like state by lowering oestrogen levels, leading to a reduction in endometrial tissue and associated symptoms.
-
Aromatase Inhibitors: These drugs reduce oestrogen production from sources other than the ovaries, helping to decrease endometrial growth and alleviate pain.
-
-
Surgery: Surgical intervention aims to remove or destroy endometrial growths, scar tissue, and adhesions. Types of surgery include:
-
Laparoscopy: A minimally invasive procedure where surgeons use a laparoscope to locate and remove endometrial tissue.
-
Laparotomy: A more extensive open surgery performed in severe cases when laparoscopy is not sufficient to remove widespread endometrial tissue.
-
Hysterectomy: In extreme cases, the removal of the uterus (and sometimes the ovaries and fallopian tubes) may be recommended if other treatments have failed and symptoms are debilitating.

FAQs
Is endometriosis life-threatening?
Endometriosis is not life-threatening, although it can cause significant pain and complications. It can also be associated with some potentially life-threatening conditions, such as ectopic pregnancy and depression, making it very important to treat.
Can endometriosis lead to infertility?
Yes, endometriosis can lead to infertility for some women, as the condition may cause scarring, adhesions, and damage to reproductive organs. However, many women with endometriosis can still conceive, and treatments are available to improve fertility outcomes.
Does endometriosis increase the risk for certain cancers?
There is currently no clear correlation between endometriosis and the risk of gynaecological cancers. There may be a slightly increased risk of certain types ovarian cancer; however, this is rare.
