Endometriosis: Symptoms, Causes, Diagnosis, and Treatment

This tissue responds to reproductivehormones and may become inflamed or irritated. Over time, endometriosis may contribute to scar tissue, adhesions, ovarian cysts, and chronic pain.

Endometriosis is not cancer, and it is not simply a “bad period.” Symptoms can affect menstruation, sexual comfort, bowel or bladder function, fertility, work, sleep, and emotional well-being.

• endo-, meaning within;
• metri-, referring to the uterus;
• -osis, meaning a condition or abnormal process.

It is generally uncountable:

• She was diagnosed with endometriosis.
• Endometriosis may cause pelvic pain and infertility.
• The surgeon removed several endometriotic lesions.

The adjective is endometriotic:

• endometriotic tissue;
• endometriotic lesions;
• an endometriotic cyst.

Common expressions include:

• symptoms of endometriosis;
• suspected endometriosis;
• deep endometriosis;
• endometriosis-related pain;
• endometriosis treatment;
• endometriosis-associated infertility.

• the ovaries;
• the fallopian tubes;
• the outer surface of the uterus;
• the pelvic lining;
• the bowel;
• the bladder;
• tissues behind the uterus.

An ovarian cyst caused by endometriosis is called an endometrioma. These cysts are sometimes informally called “chocolate cysts” because they may contain old, dark blood.

Rarely, endometriosis may affect areas outside the pelvis, including the diaphragm or chest.

Possible symptoms include:

• severe menstrual cramps;
• chronic pelvic or lower-back pain;
• pain during or after vaginalpenetration;
• pain during bowel movements;
• pain during urination;
• heavy menstrual bleeding;
• bleeding between periods;
• abdominal bloating;
• fatigue;
• difficulty becoming pregnant;
• anxiety or low mood related to chronic symptoms.

The amount of pain does not always match the visible extent of the condition. A person with limited lesions may experience severe pain, while someone with more extensive disease may have mild symptoms.

Pain may:

• begin before menstrual bleeding;
• continue throughout the period;
• occur at other times in the cycle;
• become more intense over time;
• spread into the back, hips, or legs.

Repeatedly disabling menstrual pain should not be dismissed as a normal part of menstruation.

Pain may depend on:

• penetration depth;
• sexual position;
• pressure on tender pelvic areas;
• menstrual-cycle timing;
• pelvic-floor muscle tension;
• scar tissue or adhesions;
• the location of endometriosis lesions.

A person may desireintimacy while finding penetration painful. Helpful adjustments may include controlling depth and speed, choosing positions with less pressure, using sufficient lubricant, stopping when pain begins, and exploring nonpenetrative activities.

Pain should never be forced through to satisfy a partner.

However, endometriosis does not automatically mean infertility. Many people with the condition become pregnant naturally, while others may need fertility treatment. Fertility care may include medication, surgery, intrauterine insemination, or in vitro fertilization, depending on age, symptoms, ovarian reserve, sperm factors, and other reproductive findings.

Proposed explanations include:

• menstrual tissue moving backward through the fallopian tubes;
• transformation of certain cells into endometrial-like tissue;
• immune-system differences;
• movement of cells through blood or lymphatic vessels;
• genetic susceptibility;
• tissue changes following surgery or development.

No single theory fully explains every case. Endometriosis may result from several biological mechanisms acting together.

Endometriosis:

• occurs outside the uterine cavity;
• may affect the ovaries, pelvic lining, bowel, bladder, or other structures;
• may cause adhesions and endometriomas.

Adenomyosis:

• occurs within the muscular wall of the uterus;
• may enlarge the uterus;
• commonly causes heavy bleeding and menstrual cramps.

A person may have both conditions at the same time.

• a detailed symptom history;
• menstrual and sexual-health history;
• pelvic examination;
• ultrasound;
• magnetic resonance imaging;
• assessment for other causes of pelvic pain.

Ultrasound and MRI may identify ovarian endometriomas or deeper disease, but normal imaging does not always exclude endometriosis.

A laparoscopy is a surgical procedure in which a small camera is inserted through an abdominal incision. It can allow a clinician to view lesions, take tissue samples, and sometimes remove endometriosis during the same procedure.

Possible approaches include:

• anti-inflammatory pain medicine;
• combined hormonal contraception;
• progestin treatment;
• hormonal intrauterine systems;
• medicines that suppress ovarian hormone activity;
• pelvic-floor physical therapy;
• chronic-pain support;
• surgery to remove lesions or adhesions;
• fertility treatment.

Hormonal treatments may reduce pain by suppressing ovulation or menstruation, but they generally prevent pregnancy while being used.

• pain remains severe despite medication;
• ovarian endometriomas are present;
• organs appear affected;
• fertility concerns exist;
• diagnosis remains uncertain.

Surgery may reduce pain or improve fertility in selected cases, but symptoms can return. Repeated operations may also create scar tissue or affect ovarian reserve, so benefits and risks should be discussed carefully.

A hysterectomy does not necessarily remove endometriosis located outside the uterus and is not an automatic cure.

This may contribute to:

• painful penetration;
• pain after orgasm;
• urinary urgency;
• constipation;
• aching while sitting;
• ongoing pain even after lesions are treated.

Pelvic-floor physical therapy may help when muscle tension is part of the pain pattern. Psychological or pain-management support may also help people cope with chronic symptoms without suggesting that the pain is imaginary.

• menstrual pain that disrupts normal activities;
• repeated pain during or after sex;
• persistent pelvic pain;
• pain during urination or bowel movements;
• heavy menstrual bleeding;
• unexplained difficulty becoming pregnant;
• symptoms that are worsening or not improving with treatment.

Urgent evaluation may be needed for sudden severe pelvic pain, fainting, very heavy bleeding, fever, vomiting, or pain during pregnancy.

Severe period pain is always normal.
No. Pain that repeatedly disrupts daily life deserves medical evaluation.

Endometriosis always causes infertility.
No. Many affected people become pregnant naturally.

Pregnancy cures endometriosis.
No. Symptoms may change during pregnancy, but pregnancy is not a cure.

A normal ultrasound rules it out.
No. Some forms are not visible on routine imaging.

Hysterectomy always cures endometriosis.
No. Lesions may remain outside the uterus.

1. Endometriosis may cause severe menstrual and pelvic pain.
2. Her pain during penetration was linked to deep endometriosis.
3. Can endometriosis affect fertility?
4. The ultrasound showed an ovarian endometrioma.
5. A normal scan does not always exclude endometriosis.
6. Hormonal treatment helped reduce her menstrual symptoms.
7. The surgeon discussed pain relief and fertility goals before treatment.
8. Understanding endometriosis helps readers distinguish chronic pelvic disease from ordinary menstrual discomfort.

Pain does not mean that a person lacks attraction or affection. Sexual activity can be adapted through communication, comfortable positions, nonpenetrative pleasure, and respect for changing symptoms.

Understanding endometriosis helps people recognize that sexual and menstrual pain deserve medical attention and that intimacy should always prioritize comfort, consent, and personal choice.
