Endometriosis: Symptoms, Diagnosis, and Treatment in Quebec

Endometriosis is a chronic gynecological condition that affects approximately one in ten women of reproductive age. Despite its prevalence, it remains too often diagnosed late—sometimes after years of dismissed pain. Understanding what endometriosis is, recognizing its symptoms, and knowing the options available in Quebec can make a real difference in the quality of life for those affected.

What is endometriosis?

Endometriosis occurs when tissue similar to the uterine lining (the endometrium) grows outside the uterus—on the ovaries, fallopian tubes, peritoneum, or other abdominal organs. This tissue reacts to menstrual cycle hormones, thickening and bleeding each month, but with no place to exit. This chronic inflammation causes pain, adhesions, and sometimes fertility complications.

The condition is benign (non-cancerous), but its impact on quality of life can be significant. It is classified into four stages based on the extent of the lesions, from Stage I (minimal) to Stage IV (severe), although the stage does not necessarily correspond to the intensity of the symptoms experienced.

Symptoms to recognize

The manifestations of endometriosis vary greatly from person to person. Some people have severe symptoms with few lesions, while others have extensive disease without marked pain. Here are the most frequently reported signs:

Severe menstrual pain (dysmenorrhea) that doesn't respond well to common pain relievers is often the main warning sign. This pain can occur before, during, and after periods. It can also be present throughout the cycle in the form of chronic pelvic pain.

Dyspareunia – pain felt during sexual intercourse, particularly during deep penetration – is a common symptom that is often not discussed in consultations. It is important to talk to your doctor about it.

During menstruation, some people report pain during bowel movements, constipation, diarrhea, or pain during urination. These symptoms, sometimes mistaken for irritable bowel syndrome, can indicate involvement of adjacent organs.

Heavy, prolonged periods or bleeding between periods (metrorrhagia) can accompany endometriosis.

Difficulty conceiving

Endometriosis is associated with fertility problems in a significant proportion of cases. It is identified in a substantial number of women who seek consultation for infertility, although many affected individuals manage to conceive without medical assistance.

Why is it so long to get a diagnosis?

The time between the onset of initial symptoms and a formal endometriosis diagnosis can be several years. Several factors explain this reality:

• Menstrual pain has long been downplayed, both by patients themselves and by the medical community.
• The symptoms overlap with other conditions (irritable bowel syndrome, functional pelvic pain)
• The absence of a simple, non-invasive screening test
• The definitive diagnosis traditionally requires a laparoscopy (surgical procedure).

Clinical guidelines are evolving. A clinical diagnosis based on symptoms, medical history, and imaging (ultrasound or specialized MRI) is increasingly accepted to initiate treatment, without waiting for routine surgical confirmation.

How is endometriosis diagnosed?

The first step is a detailed consultation with a doctor, which includes a precise description of the symptoms, their timing relative to the menstrual cycle, and their impact on daily life. A gynecological examination may reveal suggestive signs, such as pain on cervical motion or the presence of a nodule.

Transvaginal pelvic ultrasound performed by an experienced sonographer can detect certain types of lesions, including endometriotic ovarian cysts (endometriomas). Pelvic MRI offers a more comprehensive mapping of deep lesions and involvement of adjacent organs.

Laparoscopy remains the only way to definitively confirm the diagnosis of endometriosis. It is a procedure performed under general anesthesia that allows visualization of the lesions and, if necessary, their treatment in the same procedure. It is not systematically required to begin treatment.

Available treatment options

There is no curative treatment for endometriosis; the condition is chronic. The goal of treatment is to relieve pain, preserve fertility if desired, and improve quality of life. Management is personalized according to symptoms, pregnancy plans, and the patient's preferences.

Nonsteroidal anti-inflammatory drugs (NSAIDs) can alleviate menstrual pain. Hormonal contraception—combined pill, progestin-only pill, hormonal intrauterine device, contraceptive patch—often represents the first line of hormonal treatment. It aims to reduce hormone stimulation of lesions and the intensity of periods.

More powerful treatments like GnRH analogues may be prescribed in certain cases, under close medical supervision, due to their side effects.

Laparoscopic surgery can remove endometriosis lesions, excise adhesions, and treat ovarian endometriomas. It improves pain and, in some cases, fertility. The risk of recurrence exists after surgery, and postoperative medical treatment is often recommended.

Pelvic physiotherapy, acupuncture, and certain dietary modifications are sometimes integrated into the overall management. These approaches do not replace medical treatment, but they can contribute to well-being. Mental health support can also be beneficial, given the psychological impact of chronic pain.

Endometriosis and Mental Health

Living with a chronic, often unrecognized painful condition has a real effect on psychological well-being. People with endometriosis are at increased risk of depression and anxiety. Pain interferes with work, relationships, and daily activities. Not being heard or having to justify one's suffering adds an extra emotional burden.

Psychological or mental health support is part of comprehensive care. If you are going through a difficult time related to your condition, speak to your doctor — resources exist in Quebec to help you.

Endometriosis and fertility: what you need to know

Endometriosis can affect fertility in several ways: anatomical distortion of the fallopian tubes or ovaries, inflammation of the pelvic environment, and reduced ovarian reserve in cases of surgically treated endometriotic cysts. That said, many individuals with the condition manage to conceive naturally.

If you wish to become pregnant and have been diagnosed with endometriosis, a discussion with a fertility specialist is recommended to evaluate your individual situation and plan the best approach.

When to see a doctor

Consult a healthcare professional if you experience:

• Menstrual pain that limits your daily activities
• Persistent pelvic pain between periods
• Pain during sexual intercourse
• Difficulty conceiving after several months of trying
• Recurring digestive or urinary symptoms related to the cycle
