Endometriosis Explained: Symptoms, Diagnosis, and Laparoscopic Treatment

Endometriosis affects an estimated 1 in 10 women of reproductive age worldwide, yet it remains one of the most underdiagnosed conditions in women’s health.

Many women live with the pain for years before getting a proper diagnosis.

This guide breaks down everything you need to know – what endometriosis is, how it’s diagnosed, and how laparoscopic surgery can help.

What Is Endometriosis?

Your uterus has a lining that sheds every month during your period. Endometriosis is a condition in which tissue similar to the lining of the uterus grows outside the uterus, in places it shouldn’t, like the ovaries or pelvis.

Where it typically grows:

• Ovaries
• Fallopian tubes
• Pelvic lining (peritoneum)
• Behind the uterus
• Uterosacral ligaments

Less common locations:

• Bladder and bowel
• Rectum
• Diaphragm (rarely)

How it behaves during the menstrual cycle:

Just like the normal uterine lining, this tissue thickens and breaks down with each cycle. But unlike normal tissue, it has no way to leave the body. This leads to inflammation, scar tissue, and internal scarring over time.

Who gets it?

Endometriosis can affect any woman, from teenagers to women in their 40s.

Causes of Endometriosis

The exact cause of endometriosis isn’t fully understood. Here’s what research points to:

•  Retrograde menstruation:- Menstrual blood flows backward through the fallopian tubes into the pelvic cavity instead of leaving the body.
• Immune system dysfunction:- The immune system fails to identify and destroy misplaced endometrial-like tissue.
• Hormonal factors:- High estrogen levels fuel the growth and spread of endometriotic tissue.
• Surgical scar complications:- Endometrial cells can attach to surgical scars, such as those from a C-section.
• Lymphatic or vascular spread:- Endometrial cells may travel to distant sites through blood vessels or the lymphatic system

Endometriosis Symptoms

Key symptoms to watch for:

• Painful periods (often worse than typical cramping)
• Chronic pelvic pain, even outside of periods
• Pain during or after sex (dyspareunia)
• Heavy menstrual bleeding or spotting between periods
• Pain during bowel movements or urination
• Bloating, diarrhea, or constipation, especially around periods
• Fatigue
• Difficulty getting pregnant

Disclaimer: Symptoms vary from person to person. Some women experience severe pain, while others feel nothing at all. Pain level alone doesn’t tell you how severe the condition really is, so always consult a doctor if you experience any of these key symptoms.

Endometriosis Symptoms by Stage

Endometriosis is classified into four stages based on the location, extent, and depth of the tissue.

Disclaimer: Stage does not always predict pain levels. A woman with Stage I can experience severe pain, while someone with Stage IV may feel relaxed with no pain.

Stage I – Minimal

• Small, scattered implants on the pelvic lining or ovaries
• No significant scarring or tissue bonding
• Symptoms may be mild or completely absent
• Often discovered accidentally during surgery for another reason

Stage II – Mild

• More implants present, penetrating slightly deeper into tissue
• Small bands of scar tissue may begin to form
• Pelvic pain and cramping, particularly around periods
• Fertility is generally not yet significantly affected

Stage III – Moderate

• Multiple deep implants on the pelvic lining and ovaries
• Endometriomas (ovarian cysts) may be present
• Scar tissue starts to affect the surrounding tissue
• Pain becomes more frequent, not just during periods
• Fertility may begin to be impacted

Stage IV – Severe

• Extensive deep implants throughout the pelvis
• Large endometriomas on one or both ovaries
• Dense scar tissue causing organs to stick together
• Fallopian tubes may be blocked or distorted
• Significant impact on fertility is common
• Pain can be chronic and debilitating

Risk Factors of Endometriosis

Some women are more likely to develop endometriosis than others. Here’s what to look out for:

• Family history of endometriosis (mother, sister, or aunt)
• Never having given birth
• Early onset of periods (before age 11)
• Short menstrual cycles (fewer than 27 days)
• Heavy periods lasting longer than 7 days
• High lifetime exposure to estrogen
• Low body mass index (BMI)
• Late onset of menopause
• Structural abnormalities of the reproductive tract that block menstrual flow

What Happens If Endometriosis Is Left Untreated?

Endometriosis is a progressive condition. Without proper treatment, it doesn’t stop – it progresses, spreads, and causes more damage over time.

Many women live with the pain, thinking it’s normal period discomfort. But every month it goes untreated, endometriosis continues to damage your body, and has a high chance in affecting your fertility.

Potential consequences of leaving it untreated:

• Worsening pelvic pain that disrupts daily life
• Formation of ovarian cysts (endometriomas)
• Internal scarring that causes organs to stick together
• Fallopian tube blockage
• Infertility or reduced fertility
• Bowel and bladder complications
• Increased anxiety and depression due to chronic pain

Early diagnosis and treatment significantly improve outcomes and quality of life.

When to See a Doctor & How to Talk to Your Doctor About Endometriosis

Warning signs that need urgent medical attention:

• Period pain so severe that it stops you from doing daily activities
• Pelvic pain outside of your cycle
• Painful during sex
• Unexplained heavy bleeding

Why Is Endometriosis Often Diagnosed Late?

• There is no simple blood test or non-invasive screening that definitively confirms it
• Symptoms overlap with other conditions like IBS, pelvic inflammatory disease, and ovarian cysts
• Many women are unaware that painful periods are not always normal, and sometimes, period pain is considered normal by both patients and some doctors

According to the WHO, on average, it takes 4 to 12 years for endometriosis to be diagnosed. (https://share.google/aimode/VUFG1np8lPKFORo2O)

Tips for communicating your symptoms clearly:

• Track your pain – note when it starts, how long it lasts, and its intensity
• Mention all symptoms, even digestive or urinary ones
• Be specific about how pain affects your daily routine
• Be honest about your symptoms, describe them exactly as you feel them

Key Questions to Ask Your Doctor

• Could my symptoms be endometriosis?
• What tests will confirm the diagnosis?
• How advanced might my condition be?
• How will this affect my fertility?
• What treatment options are available for me?
• Are there non-surgical treatments I should try first?
• What are the risks of laparoscopic surgery?
• Will endometriosis come back after treatment?
• How can I manage pain day-to-day?
• Should I see a specialist – an endometriosis specialist or a gynaecologist?

Be Prepared With these Questions: What a Doctor May Ask (In General)

• Symptom history:- When symptoms started, how frequently they occur, and their severity
• Menstrual cycle details:- Cycle length, bleeding heaviness, pain patterns
• Family history:- Any relatives diagnosed with endometriosis
• Earlier treatments taken:- Any medications, hormonal therapies, or pain management you’ve already tried

Diagnosis & Tests

How Is Endometriosis Diagnosed?

Physical / Pelvic Examination The doctor checks for tenderness, nodules, or abnormal masses in the pelvic area. An exam alone cannot confirm endometriosis, but it gives the doctor a useful starting point.

Tests Used to Detect Endometriosis?

• Transvaginal Ultrasound:- Helps detect ovarian cysts (endometriomas) and larger areas of affected tissue. It cannot identify small implants.
• MRI Scan:- Provides a more detailed picture of the pelvis. Useful for mapping deep endometriosis before surgery.
• Laparoscopy:- A minimally invasive surgical procedure where a camera is inserted through a small incision to directly visualise endometrial tissue. This is the only definitive way to confirm the diagnosis.
• Biopsy during laparoscopy:- A small tissue sample is removed during the procedure and examined under a microscope to confirm endometriosis.

Treatment Options for Endometriosis

Treatment depends on the severity of the condition, your symptoms, and whether pregnancy is planned. There is no permanent cure, but symptoms can be effectively managed.

Surgical Treatment – Laparoscopy

What is laparoscopic surgery?

Laparoscopy is a minimally invasive, keyhole surgical procedure used to both diagnose and treat endometriosis. It is performed under general anaesthesia.

How it is performed:

• A small incision is made near the navel
• A thin camera (laparoscope) is inserted to visualise the pelvic organs
• Additional small instruments are used to remove or destroy endometrial tissue and adhesions

What the surgeon looks for and removes:

• Endometriotic implants and lesions
• Ovarian cysts (endometriomas)
• Adhesions bind pelvic organs together
• Scar tissue causing pain or blockages

Recovery timeline:

•  Most patients return home the same day or within 24 hours
• Light activity can usually resume within 1–2 weeks
• Full recovery typically takes 2–4 weeks, depending on the extent of surgery

When surgery is recommended:

• Symptoms are not responding to hormonal or pain-relief medications
• Ovarian cysts (endometriomas) are present
• Fertility is affected and needs to be restored
• Severe adhesions or organ involvement are suspected

While reading and hearing about these, you feel tense and stressed. No need for that when you are in the right care and with the top specialist.

Non-Surgical Treatments

For mild to moderate cases, non-surgical treatments are often prescribed:

• NSAIDs (e.g., ibuprofen):- Over-the-counter pain relief to manage period and pelvic pain
• Hormonal therapies:- Birth control pills, progestins, or hormonal IUDs to suppress the menstrual cycle and reduce tissue growth
• GnRH agonists/antagonists:- Medications that temporarily lower estrogen levels, shrinking endometriotic tissue
• Danazol:- A hormone-suppressing drug that reduces estrogen and stops tissue growth; used in specific cases

Disclaimer: Hormonal treatments manage symptoms but do not permanently eliminate endometriosis. Symptoms may return after stopping medication.

Hysterectomy

In severe cases where other treatments have failed, surgical removal of the uterus (hysterectomy) may be considered. This option is only discussed when pregnancy is not planned, and the condition remains uncontrolled.

Complications of Endometriosis

When endometriosis is not properly treated, it can lead to serious complications:

• Infertility:- Endometriosis is one of the leading causes of infertility in women. Among women struggling to conceive, 30% to 50% are found to have the condition.
• Ovarian cysts (endometriomas):- Blood-filled cysts that form on the ovaries; they can affect ovarian function
• Internal scarring and organ damage:- Bands of scar tissue that cause organs to stick together, leading to chronic pain and structural damage
• Bowel and bladder complications:- Pain, bleeding, or dysfunction when the tissue grows near the intestines, rectum, or bladder
• Sexual dysfunction:- Chronic pain during sex (dyspareunia) can significantly impact relationships and quality of life
• Increased cancer risk:- Rare, but research shows a slightly elevated risk of ovarian cancer in women with long-standing endometriosis
• Psychological impact:- Chronic pain, infertility concerns, and disrupted daily life contribute to anxiety and depression in many women

Disclaimer: The information shared in this blog is intended for general awareness. Endometriosis is a real, complex condition, not just painful periods. If you recognise these symptoms in yourself, don’t ignore them. Early diagnosis and the right treatment make a significant difference in managing pain, protecting fertility, and improving your quality of life.
