What are the Symptoms of Endometriosis?


Endometriosis is a complex disease of the female reproductive system in which tissue similar to the lining of the uterus grows outside the womb. This disease can cause pain, fertility problems, severe menstrual cramps, menstrual delay, severe pain during and after sexual intercourse, and bowel problems.

What Is Endometriosis?

One of the most common diseases in women is endometriosis, the abnormal growth of uterine tissue outside the uterus. Mainly, this tissue is formed in the pelvis, ovaries, fallopian tubes, peritoneum, and the wall separating the anus and pelvis. We should note that endometriosis can also grow on cesarean wounds, laparoscopy wounds, bladder, intestine, appendix, and anus. The most crucial symptom of endometriosis is severe pain in the pelvic area. This pain often occurs during the menstrual cycle and sometimes before or after. 

It should be noted that the upper transient tissue of the uterus sheds during menstruation, but this does not happen if the tissue is formed outside the uterus. As a result, endometriosis can have a wide range of side effects on the body. Complications of endometriosis include the obstruction of the fallopian tubes, difficulty in having sexual intercourse, difficulty in doing daily activities and working, and infertility. 

Endometriosis is an abnormal growth of uterine tissue outside the uterus.

Endometriosis Stages

Endometriosis occurs in four stages; therefore, it has four types of symptoms and complications. The stages of endometriosis are determined according to the tissue's location, size, number, and depth. In the following, the four stages of endometriosis are introduced. 

Stage 1 Endometriosis (Minimal)

At this stage of endometriosis, the endometrial tissue is shallow, and the severity of the disease is very low. In minimal endometriosis, these problems may occur:

  • Inflammation in and around the pelvic cavity;
  • The emergence of minor wounds inside the ovaries;
  • Irritation in the intestines and bladder;
  • Pain during sex;
  • Painful periods; and
  • Excessive menstrual bleeding.


Stage 2 Endometriosis (Mild)

The symptoms of mild endometriosis are the same as minimal endometriosis but with deeper endometrial layers. Since light lesions are formed in the ovaries and pelvis during mild endometriosis, the last two weeks of the menstrual cycle are more painful. Also, you may experience pain during or after sex and while urinating, nausea, constipation, or diarrhea when you have stage 2 endometriosis. 

Stage 3 Endometriosis (Moderate)

In moderate endometriosis, more lesions are formed, and the depth of endometrial tissue in the ovaries and pelvic lining also increases. At this stage, some cysts and adhesions are formed in one or both ovaries that cause severe pain in the pelvis and abdomen.

Endometriosis may cause ovulation disorders and infertility.

Stage 4 Endometriosis (Severe)

In stage 4 endometriosis, the lesions are deeply implanted in the pelvis and ovaries or the intestines and fallopian tubes. The more endometriosis layers increase, the more pain and digestive problems increase; therefore, removing cysts is necessary.

It should be noted that severe cases of endometriosis can lead to infertility as it causes problems such as low egg quality, inflammation of the fallopian tubes, and adenomyosis or heterogeneous myometrial. However, mild to moderate endometriosis does not usually cause infertility.

Endometriosis Symptoms

The first and most common sign of endometriosis is pain in the pelvis, especially during menstruation. This pain may occur in different areas and at different times. Some other symptoms of endometriosis include:

  • Pain in the abdomen during menstruation that cannot be controlled by common painkillers such as ibuprofen;
  • A menstrual period that lasts more than seven days;
  • Severe bleeding accompanied by blood clot discharges during the menstrual period;
  • Menstrual cycle less than 27 days;
  • Pain in the lower abdomen during urinating or bowel movement;
  • Intestinal disorders and irritable bowel syndrome (IBS) with symptoms such as diarrhea, constipation, stomachache, and bloating;
  • Pain during or after sex;
  • Chronic pain in the lower back;
  • Nausea and vomiting;
  • Constant fatigue;
  • Pain during examination by a doctor;
  • Depression;
  • Bleeding and spotting between menstrual periods;
  • Painful intestine movements and bleeding when defecting; and
  • Feeling pain in legs.


Endometriosis Symptoms


In some cases, the above symptoms are caused by other diseases such as ovarian cysts, pelvic inflammatory disease (PID), or irritable bowel syndrome (IBS). Therefore, doctors must carefully determine the leading causes of such symptoms before doing any treatment.

What Does Endometriosis Feel Like?

Many patients have declared that the pain of endometriosis is similar to that of the menstrual period but sharper and more severe. In endometriosis, the cramps are like stabbing in the stomach, and the patient cannot control them by taking regular OTC painkillers. Also, women with endometriosis have intolerable pain in the pelvis and belly during and -even two days- after sexual intercourse. 

When Does Endometriosis Pain Occur?

In almost all cases, the endometriosis pain emerges two or three days before the menstruation and continues for a couple of days after it. Also, in some women, the pain occurs even during and after sex, during bowel movement and urinating, while exercising, and between two periods.

Where Is Endometriosis Pain Located?

In most cases, the pain of endometriosis is not located in a certain location, and the patient feels it in different parts of the body. In general, endometriosis’s pain is located in one of the following parts:

  • Bowel;
  • Fallopian tubes;
  • Ovaries;
  • Uterus and other areas surrounding the uterus;
  • The lower back;
  • Pelvic area;
  • Intestine;
  • Bladder;
  • Thighs;
  • Neck and shoulders.


What Causes Endometriosis?

The leading causes of endometriosis are still unknown. But scientists believe that estrogen will worsen endometriosis. That's why estrogen-regulating drugs are used to treat endometriosis. In addition to estrogen production, other factors cause endometriosis, such as:

  • Genetic or inherited problems;
  • Growth of stem cells in the pelvic and gastric mucosa;
  • Transfer of endometrial cells by the lymphatic system to different parts of the body;
  • Immune system disorders;
  • Deformation of embryonic stem cells into endometrial-like cells due to stimulation of some hormones such as estrogen;
  • The problem in menstrual blood flow that causes its entry into the pelvis or fallopian tubes instead of leaving the body;
  • Being over the age of 35 years;
  • Not exercising;
  • Drinking too many caffeinated and alcoholic beverages;
  • Low body mass index (BMI);
  • Early menstruation;
  • Late menopause; 
  • Genital disorders, etc.


Estrogen is one of the main causes of endometriosis

Complications of Endometriosis

Endometriosis, as one of the most common and complicated diseases in women, has multiple complications such as:

  • Diarrhea and constipation;
  • Bloating and nausea;
  • Severe or irregular bleeding during menstruation;
  • Infertility;
  • Cramping;
  • Ovarian cysts;
  • Intestinal and bladder problems such as ileus;
  • Increased risk of ovarian and breast cancer;
  • Rupture of cysts and lesions;
  • Adhesion and scarring of internal tissues; and
  • Inflammation of the surrounding areas of endometriosis.


Who Is More Likely to Get Endometriosis?

People with a family history of endometriosis are more likely to get this disease. Also, women who:

  • Are between the ages of 25 and 35,
  • Have no account of childbearing,
  • Had endometriosis in the past,
  • Have irregular periods longer than seven days with the interval of fewer than 27 days, and
  • Undergone menstruation before the age of 12.


In general, endometriosis is highly dependent on sex hormones such as estrogen; therefore, being at the reproductive age increases the risk of developing this disease in women.

How Is Endometriosis Diagnosed?

There are several ways to diagnose endometriosis and its severity. Some lead to a definitive diagnosis of the disease, and some rule out the possibility of other conditions.

Some ways of diagnosing endometriosis include:

  • Endometriosis ultrasound
  • Having a detailed medical history
  • Pelvic examination
  • Differential diagnoses
  • Laparoscopy and biopsy
  • MRI
  • Blood test


Endometriosis ultrasound

The doctor can perform a transvaginal or transabdominal ultrasound to diagnose the endometriosis in the uterus, ovaries, bladder, and intestines.

Using ultrasound is a way to diagnose endometriosis.

Having a detailed medical history

Doctors recommend patients report their problems, such as painful menstruation, pain during intercourse, and spotting before menstruation, to the doctor.

Pelvic examination

Clinical examinations of the pelvis and the surrounding organs are essential in identifying the early signs of Endometriosis.

Differential diagnoses

Doctors can diagnose Endometriosis by comparing its symptoms with other diseases with similar signs, such as ovarian cysts, pelvic inflammatory disease (PID), and irritable bowel syndrome with common symptoms such as abdominal pain, diarrhea, constipation, etc.

Laparoscopy and biopsy

Laparoscopic surgery and biopsy of the internal organs is the only definitive way to diagnose Endometriosis. Laparoscopy can determine the size, location, and depth of endometriosis.

laparoscopic surgery

MRI

By imaging the internal organs of the pelvic cavity and observing their condition, the doctor can detect the development of endometriosis.

Blood test

A blood test is ineffective for diagnosing endometriosis, but doctors may use it to check hormones.

Endometriosis Treatment

Since the causes of endometriosis are not yet known, there is no definitive treatment for it. However, most physicians suggest one of the following treatments to the patients based on the severity of their disease, their symptoms, their age, and their desire to have children in the future.

In the following, we introduce the most common methods of treating endometriosis and endometriosis medication:

  • Dietary modification
  • Taking analgesics
  • Laparoscopy
  • Hormone therapy
  • Removing the ovaries and uterus
  • Progestin therapy
  • Taking gonadotropin-releasing hormone (Gn-RH) agonists
  • Using ARTs


Dietary modification

People with endometriosis should avoid fatty foods, red meat, and animal by-products because these foods can increase estrogen production in the body.

Eating high-fat foods is harmful for endometriosis.

Taking analgesics

The doctors usually ask the patients to take nonsteroidal anti-inflammatory drugs such as naproxen, ibuprofen, and mefenamic acid to reduce their pain during menstruation.

Laparoscopy

The best way to treat and diagnose endometriosis is laparoscopy or, in severe cases, laparotomy.

Hormone therapy

By taking hormonal medications, the amount of estrogen in the body gets balanced, and therefore, the pain of endometriosis is reduced to a great extent.

Hormonal therapy, one of the ways to treat endometriosis by regulating estrogen

Removing the ovaries and uterus

Removing the ovaries (oophorectomy) and uterus (hysterectomy) is the last option in treating endometriosis because the patient cannot get pregnant after these surgeries.

Progestin therapy

Subdermal progestin implants, levonorgestrel intrauterine devices (IUD), injectable contraceptives, and progestin pills stop the growth of endometrial tissue.

Taking gonadotropin-releasing hormone (Gn-RH) agonists

Taking these medications lowers estrogen levels, stops the production of ovarian-stimulating hormones, and prevents menstruation; as a result, the endometrial tissue will shrink.

Using ARTs

In some cases, assisted reproductive techniques such as IVF treatment or IUI treat endometriosis-related infertility.

Endometriosis and Infertility

About 30 to 50% of women with endometriosis have fertility problems because this disease causes:

  • Adhesion and scarring in the uterus;
  • Limitation in egg growth;
  • Reduction in egg production and quality;
  • Disorders in the ovulation process;
  • Changes in the pelvic anatomy;
  • Pelvic inflammation;
  • Hormonal imbalance; and
  • Blockage of the fallopian tubes.

As it was mentioned above, most women with endometriosis have ovulation problems. For this reason, the doctor may prescribe fertility and ovulation induction drugs. As soon as ovulation begins, the doctor uses IVF or IUI procedures to increase the chance of pregnancy. 

We should note that some treatments for endometriosis can prevent pregnancy or cause congenital disabilities; therefore, the whole treatment process should be done under the supervision of a skilled and experienced physician. Treatment for endometriosis to treat infertility is also time-consuming, so it should begin without delay.

Endometriosis and Uterine Cancer

The relationship between endometriosis and uterine cancer has not yet been found. Endometriosis does not cause uterine cancer in all patients, but some cancers, such as breast cancer, are more common in women with this disease.

Uterine or endometrial cancer, which starts from the endometrial tissue, shows symptoms such as bleeding and spotting after menopause, between menstrual periods, and pelvic pain. Chronic inflammation and estrogen stimulation in patients with endometriosis increase the risk of endometrial cancer. So, if you notice any of the mentioned symptoms, visit your doctor and get a complete checkup before it's too late.

FAQs about Endometriosis

1) Is endometriosis common?

Generally, %11 women between the age of 15 to 40 have endometriosis. This disease appears and reaches its highest point in the third decade of women's life.

2) Does endometriosis get better after menopause?

In most cases, the severe pain of endometriosis reduces after menopause because the body does not produce estrogen anymore. However, if the symptoms of endometriosis continue after menopause, they should be surgically treated.

3) Does endometriosis cause infertility?

Although endometriosis damages the egg cells and causes hormonal imbalance, it does not necessarily cause infertility. However, women with endometriosis have more complicated pregnancies and a higher rate of miscarriage. 

4) Does endometriosis get better after having a baby?

It depends on each individual's body. Many women won't experience endometriosis symptoms as long as they are breastfeeding and not menstruating.  

5) Can I prevent endometriosis?

Generally speaking, No. You cannot prevent endometriosis, but if you have a family history, you can lower its risk by controlling and reducing the estrogen level in your blood. To do so, you should reduce the intake of alcohol, caffeine, and red meat intake and exercise regularly.

    Hi there. I've been feeling pain around my belly for about a month. Can you see endometriosis on an ultrasound? Can I trust the result?
