What are the symptoms of endometriosis?

The symptoms are multiple and vary from one patient to another. In fact, since different organs can be affected, the symptoms vary greatly from one woman to another. Just as sometimes, no symptoms are felt and the disease then remains "silent".

La plupart des symptômes sont cycliques et accentués par les menstruations, puisque les lésions sont influencées par les variations hormonales .
L’étendue de la maladie n’est par contre pas nécessairement proportionnelle à la sévérité des douleurs ressenties par la patiente. Par contre, une invasion profonde de l’endométriose à proximité de nerfs cause probablement des douleurs plus importantes (douleurs neuropathiques liées à l’endométriose).

However, there is not always a correlation between the intensity of the disorders and the degree of severity of the disease. This explains why extensive or deep forms of endometriosis are not necessarily very painful, and less extensive and superficial forms are sometimes very painful.

Dysmenorrhea (menstrual pain)

This is the first symptom that may indicate endometriosis. Menstruation must not be abnormally painful, it is a physiological phenomenon that must allow you to continue your activities. If this is not the case, and the menstrual pain is severe, violent, or leads to school or professional absenteeism, then endometriosis must be suspected.

Digestive symptoms

Pain when having a bowel movement (especially during menstruation), blood in the stool (during menstruation), constipation, diarrhea (or alternation of the two), severe discomfort, bloating. These disorders are probably related to the inflammation of endometriosis lesions.

Menorrhagia (very heavy periods)

This is another common sign of the disease.


Pain during intercourse, especially in the vagina.

Urinary symptoms

Urinary burns, difficulty urinating (during menstruation), very frequent urges to urinate.

Symptoms of rheumatologic appearance

Sciatic or shoulder pain (especially on the right).

Lung symptoms (very rare)

The occurrence, during menstruation, of pain in the right shoulder, or an air (pneumothorax) or blood (hemothorax) effusion is a sign of damage to the diaphragm, pleura or lung.


Endometriosis is often diagnosed during an infertility check-up. 30 to 40% of the women affected have to face an infertility problem.

Chronic pelvic pain (pelvic hypersensitivity)

Their appearance marks a turning point in the disease. These pains can be almost permanent, day and night. They are of the burn or electric discharge type and persist even when not menstruating. They radiate into the pelvis, lower abdomen, back, lumbar region, and thighs. They are often described as unbearable and end up leading to work or school stoppages. Deep endometriosis invades the nerve fibres of the small pelvis, in case of superficial endometriosis their origin is less explicit.

Chronic fatigue

This symptom results more as a consequence of all the above symptoms and the resulting pain that women with endometriosis have to face.
