Endometriosis: Understanding the Condition and Getting Treated in France with ELSAN

Endometriosis means tissue similar to the endometrium grows outside the uterus. The endometrium is the lining inside the uterus.

This tissue can appear on the ovaries. On the fallopian tubes. On the peritoneum. Rarely, on the intestine.

It stays sensitive to female hormones, especially estrogen. With each cycle, it thickens then bleeds, just like the uterine lining. The result: local inflammation, then fibrous scarring, then adhesions between organs.

According to Inserm, France's national health research institute, one in ten women of childbearing age is affected.
Long overlooked, the condition now gets growing institutional attention in France. There's even a dedicated national strategy.

Pelvic pain dominates. It often gets worse during periods: that's dysmenorrhea, the medical term for painful periods.

This pain goes well beyond normal discomfort. It can limit work, studies, social life.

Other signs sometimes come with the condition:
•    pain during intercourse
•    cyclical digestive or urinary discomfort
•    chronic fatigue
•    difficulty conceiving

And sometimes, no symptoms at all. Endometriosis then gets discovered during a fertility work-up. Which often means a late diagnosis.
 

It starts with a thorough conversation with the doctor: which symptoms, what link to the cycle, what impact day to day?

Then comes the gynecological exam. Then a pelvic ultrasound, as the first-line test.

If results stay unclear, or deep lesions are suspected, a pelvic MRI (magnetic resonance imaging) steps in. It pinpoints exactly where the lesions are.

 

Good to know: menstrual pain is too often dismissed as normal, sometimes even by healthcare professionals. A specialist opinion, at a dedicated endometriosis center, usually speeds things up.

Three main levers: medical treatment, surgery, and broader pain management. The choice depends on symptom severity, how far the lesions have spread, and whether pregnancy is a goal.

Hormonal treatment comes first. Continuous-use birth control pills, or GnRH agonists — a class of medication that reduces estrogen production. The goal: put the ovaries to rest and slow lesion progression. This treatment eases pain. It doesn't erase tissue that already exists.

Surgery goes further. According to Inserm, it's the only treatment that fully removes endometriosis lesions. It's performed by laparoscopy — a minimally invasive technique using small incisions. Two approaches exist:

•    excision, which removes the lesions entirely

•    ablation, which destroys them by coagulation, without removing them

The choice between the two depends on where the lesions sit, how deep they go, and whether the patient plans to become pregnant. A well-performed surgery can bring lasting relief. Sometimes permanent.

Pain management, finally. Around these treatments, a team gets involved: a specialized gynecologist, a pain specialist, and, when relevant, a fertility specialist. Pelvic physiotherapy, osteopathy, and psychological support sometimes complete this pathway.

Already have a diagnosis? Already been offered a treatment back home? Before considering a trip to France, ELSAN offers a second medical opinion — remotely, without leaving home.

An ELSAN specialist reviews your file. They can confirm the diagnosis, suggest a therapeutic alternative, or simply provide additional insight before an important decision.

•    Response time: between 48 hours and 10 days
•    Format: written report, or teleconsultation
•    Cost: €250, all-inclusive — sometimes covered by private insurance
•    Travel: none required. A second opinion doesn't qualify for a medical visa
If the opinion favors surgery, ELSAN then guides you toward a cost estimate and stay organization, with the surgeon who reviewed your file.

A complete file means a faster pathway. Whether for a second opinion or full treatment, ELSAN asks for three documents:

1.   A recent medical report — less than 3 months old, written by your treating physician. Medical history, current treatments, symptoms, clinical exams.

2.   Your supporting exams, clearly readable — imaging (MRI, ultrasound, CT scan), lab results, and any histology report.

3.   A letter from your local doctor — stating the medical question you want ELSAN to address. It helps the surgeon focus their analysis.

Good to know: avoid simple photos of documents, which are often hard to read. A good-quality scan makes analysis easier. Files in French or English are accepted as is; any other language requires a certified translation.

If your file isn't complete, ELSAN can connect you with a partner medical concierge service in your country to help put it together.
 

212 facilities. All across France. Several clinics with teams trained in minimally invasive gynecological surgery and endometriosis care.

French medicine holds a solid international reputation. Physician training, technical platforms, protocols: the bar sits high.

But ELSAN goes further for international patients. A dedicated office, present in every facility, coordinates everything:
•    medical file review
•    connection with the physician
•    stay organization
•    follow-up after the procedure

No bad surprises. No unnecessary travel. Here's how ELSAN organizes care for a patient without French social security coverage.

1.    Send the medical file — recent report, imaging, lab results.

2.    Review by an ELSAN physician — to confirm treatment in France makes sense.

3.    Treatment plan and cost estimate — the proposed protocol, priced in detail.

4.    Deposit or payment guarantee — the procedure date gets confirmed once the deposit is paid, or a guarantee letter arrives from the insurer.

5.    Medical visa documents — ELSAN provides what's needed.

6.    Stay in France — private room, with a bed for a companion if needed.

7.    Post-operative follow-up — a check-up, then a report sent to the referring physician.

Worth remembering: European patients may, under certain conditions, get the S2 form from their home insurance fund. Outside the European Economic Area, it depends on a possible bilateral agreement between France and the patient's country of residence.

Without French social security coverage, care gets paid in full. No bad surprises, though: ELSAN provides a detailed cost estimate before any scheduled procedure.

This budget includes:

Travel insurance, or private health insurance covering care in France, is strongly recommended. Without it, a payment plan may be arranged after the administrative team reviews the file.
