Because period pain should not steal your life.

Many women grow up believing that pain is simply “part of being a woman.” Pain during menstruation is often normalised, brushed aside, or even joked about—until one day it becomes unbearable.

But there is a difference between mild period discomfort and pain that signals that something deeper may be happening inside the pelvis.

One of the most common reasons nearly 10% of young women worldwide suffer silently for years is endometriosis—a condition that can affect not only the womb, but also the ovaries, bowel, bladder, pelvic nerves, and surrounding tissues. It is also one of the most misunderstood conditions in women’s health, and is often ignored.

What is Endometriosis?

Endometriosis happens when tissue similar to the lining of the uterus (the endometrium) grows outside the uterus, where it does not belong. This triggers chronic inflammation and can lead to long-term complications.

This tissue can be found on the ovaries, fallopian tubes, pelvic peritoneum (the lining inside the pelvis), bowel and rectum, bladder, ureters (the tubes that carry urine from the kidneys), deeper pelvic ligaments and nerves, and in rare cases, even areas beyond the pelvis.

As a result of repeated inflammation that flares up during each menstrual cycle, endometriosis may eventually lead to:

scarring and adhesions (pelvic organs sticking together)
ovarian endometriomas (“chocolate cysts”)
debilitating pain that worsens over time
fertility challenges in some women

Endometriosis is not “just a bad period.” It is a real medical condition, and it deserves proper attention If left untreated, deeply infiltrating endometriosis can lead to serious complications such as intestinal obstruction, ureteric stenosis, hydronephrosis, and kidney damage. According to the literature, about 1–3% of endometriosis cases may undergo malignant (cancerous) transformation.

How Do You Know When Your Period Pain is NOT Normal?

Many women experience mild cramps on the first day of their period. This is common.

However, pain should never:

stop you from going to school or work
make you faint, vomit, or feel paralysed
require repeated visits to the emergency department
require strong painkillers every month
worsen year after year
affect your mental health and relationships

Key Symptoms of Endometriosis You Shouldn’t Ignore

Endometriosis can look different in every woman. Some have mild symptoms, while others suffer severely. The intensity of symptoms does not always match the “stage” of the disease.

Endometriosis may start early in adolescence, sometimes soon after the first period (menarche).

Here are the most common symptoms.

1) Painful Periods (Dysmenorrhoea) That Are Severe or Getting Worse

This is often the earliest symptom and is experienced by the majority of women with endometriosis.

You may notice cramps that:

start days before the period begins

last throughout the period

persist even after the period ends

The pain may radiate to the lower back or thighs and can make it difficult to stand or walk properly.

2) Chronic Pelvic Pain (Pain Even When You’re Not Having Your Period)

Endometriosis pain does not always follow the calendar.

You may experience:

persistent heaviness or aching in the pelvis

random stabbing pains

discomfort after standing too long

pain after exercise

pain that flares unpredictably

Many patients feel frustrated because they look “normal” on the outside—yet they are fighting pain every day.

3) Pain During Sex (Dyspareunia)

This is an important but sensitive symptom, and many women feel too embarrassed to bring it up.

Pain may occur:

during deep penetration

after intercourse (lasting hours or even days)

as pelvic soreness that affects intimacy and confidence

Deep pain during sex can be linked to deep endometriosis, especially behind the uterus or involving pelvic ligaments.

4) Bowel Symptoms: Constipation, Painful Bowel Movements, or “IBS-like” Symptoms

Endometriosis is often misdiagnosed as “gastric” problems.

You may experience:

constipation that worsens during menstruation

painful bowel motion (dyschezia)

bloating that makes you look “pregnant” (“endo belly”)

cramps after eating

alternating bowel habits (constipation and diarrhoea)

Some women are told they have Irritable Bowel Syndrome (IBS) and are treated for IBS for many years before finally being diagnosed with endometriosis.

IBS is real—but when bowel symptoms are closely tied to menstruation and pelvic pain, endometriosis must be considered.

5) Bladder Symptoms: Painful Urination or Frequent Urge

Endometriosis can affect areas near the bladder or ureters.

You may notice:

pain during urination or after voiding, especially around menstruation

frequent urge to urinate

UTI-like symptoms, but urine tests keep coming back negative

It is not uncommon for many women to be repeatedly treated for urinary tract infection, only to later discover that the real cause is endometriosis.

6) Heavy Menstrual Bleeding and Clots

Not all women with endometriosis have heavy periods, but many do—especially those with co-existing conditions such as adenomyosis or uterine fibroids.

If you experience:

soaking pads every hour or two

passing large clots

bleeding longer than 7 days

fatigue or low iron (anaemia)

…do not assume it is normal.

You may also have adenomyosis, which often co-exists with endometriosis. Adenomyosis occurs when uterine lining tissue grows into the muscle wall of the uterus, causing:

extremely painful and heavy bleeding

an enlarged, tender uterus

7) Fatigue That Doesn’t Improve With Rest

Fatigue is one of the most overlooked symptoms.

This may be due to chronic inflammation that exhausts the body, poor sleep from pain, hormonal fluctuations, iron deficiency from heavy bleeding, or emotional stress from living with an invisible illness.

If your fatigue is persistent, it deserves evaluation—not dismissal. Endometriosis drains energy and can dampen the soul.

8) Fertility Challenges

According to many studies, about 45–50% of women with infertility may have endometriosis. However, many women with endometriosis do become pregnant naturally too, while others may require medical assistance.

Women with endometriosis who conceive may also have a higher risk of:

miscarriage

premature delivery

poor obstetric outcomes

Endometriosis can reduce fertility due to:

inflammation affecting egg quality

adhesions distorting pelvic anatomy

blocked fallopian tubes

ovarian endometriomas affecting ovarian reserve

If you have been trying to conceive for 12 months (if age <35), or 6 months (if age ≥35), and you also have symptoms of endometriosis, do not wait. Early assessment can save time and emotional heartbreak.

Red Flags: When You Should Seek Help Early

If you have any of the following, it is strongly recommended to see a doctor with experience in endometriosis:

RED FLAGS

1 pain that makes you miss work or school every month
2 pain that worsens each year
3 pain requiring strong painkillers regularly
4 pain during sex
5 bowel/bladder symptoms linked to periods
6 persistent pelvic pain beyond menstruation
7 history of ovarian cysts or surgery
8 fertility concerns
9 previous surgery but pain returned quickly

How is Endometriosis Diagnosed?

Diagnosis depends on symptoms, examination, and imaging.

1) Clinical assessment

A detailed history often gives the strongest clue and based on this alone, the diagnosis can be made with almost 80% accuracy.

2) Ultrasound / MRI

Ultrasound of pelvis or MRI to diagnose and map the endometriosis are both equally accurate and useful. Specialised imaging can detect:

endometriomas (chocolate cyst)

the location of deep infiltrating endometriosis

adenomyosis or fibroids

pelvic adhesions and organ fixation

However, imaging requires both experience and the right technique. Not all general gynaecologists are trained in ultrasound to detect endometriosis, and not all radiologists are trained to interpret endometriosis accurately on MRI.

3) Laparoscopy (keyhole surgery)

Most endometriosis cases can be suspected and diagnosed accurately through clinical assessment and imaging. Treatment can often be initiated based on clinical diagnosis alone.

However, some women may require diagnostic laparoscopy for a definitive diagnosis and proper treatment.

Minimally invasive surgery may be recommended when:

symptoms are severe

medical treatment does not work

fertility is affected

deep disease is suspected

diagnosis and treatment need to be done together

What Can You Do If You Suspect Endometriosis?

Here are simple steps you can start today:

1. Track your symptoms

Write down:

pain score (0–10, no pain, 10 maximum pain)
days of pain per month
bowel/bladder symptoms
triggers and relief methods
bleeding pattern

If your pain score is consistently >6/10, it may suggest a significant underlying issue and should be assessed.

2. Stop normalising suffering

Pain is not your personality. You are not weak.

You are not “overreacting.”

You are listening to your body.

3. See the right team early

At Hospital Picaso, endometriosis care is delivered through a multidisciplinary team, bringing together gynaecologists and other specialists when needed. Coordinated care helps ensure accurate diagnosis, personalised treatment, and better long-term outcomes.
