What is Endometriosis? Endometriosis happens when tissue like the lining of the womb (uterus) grows in places it does not belong — like on the ovaries, the fallopian tubes, or other parts of the pelvis. In rare cases, it can even show up in places far from the womb, like the lungs or surgical scars.

This tissue behaves like it would inside the womb — it reacts to monthly hormonal changes, swells, and bleeds during periods. But because it is trapped outside the womb, it can cause pain, swelling, and sometimes scar tissue.

Why Does It Happen? Doctors are not completely sure why endometriosis develops. One main theory is retrograde menstruation — where some menstrual blood flows backward into the pelvis instead of out of the body. These cells then stick to other tissues and grow.

We also know that: — It mostly affects women who are having regular periods and have working ovaries. — Pregnancy and breastfeeding often ease symptoms because periods stop for a while. Endometriosis usually goes away after menopause when periods stop permanently.

How Common is It? We do not know the exact number because many women have no symptoms.

But it is estimated that: — Around 1 in 3 women with endometriosis have trouble getting pregnant. Around 1 in 3 women with fertility problems have endometriosis. — In India alone, over 40 million women may have it.

What Are the Symptoms? Some women have no symptoms at all. For others, endometriosis can cause: — Very painful periods — Pain during or after sex — Difficulty getting pregnant — Pain when passing stools or urine (especially during periods) — Ongoing pelvic pain

Does It Cause Infertility? This is still debated. In some cases, scar tissue or adhesions from endometriosis can block the fallopian tubes or affect the ovaries, making pregnancy harder. But in many women, the link between endometriosis and infertility is unclear. Some experts even suggest infertility can sometimes lead to endometriosis rather than the other way around.

How is it Diagnosed? The only sure way to confirm endometriosis is through a small surgical procedure called laparoscopy — where a tiny camera is inserted into the abdomen. Even then, samples are taken and usually checked under a microscope to be sure.

Scans like ultrasound can detect endometriomas (a type of cyst caused by endometriosis), but they can miss smaller or hidden spots.

Treatment Options: Treatment depends on whether the main problem is pain, infertility, or both.

1. Hormonal treatments (such as birth control pills, progestins, or hormone-blocking injections) can relieve pain but usually prevent ovulation, making them unsuitable for those trying to conceive. — Surgery can remove endometriosis patches, but symptoms can return. Surgery is advised when there’s severe pain, bowel or urinary blockage, or suspicion of cancer.

2. For infertility, mild cases may be addressed with fertility treatments such as ovulation stimulation and intrauterine insemination (IUI). — For more severe cases or if other treatments fail, IVF is usually the best choice. — Removing endometriomas before IVF does not usually improve success rates and may reduce egg numbers, so it is often avoided unless necessary.

Living with Endometriosis: Endometriosis can be frustrating & unpredictable — symptoms can be mild, severe, or even disappear on their own. The key is to tailor treatment to the woman’s main concerns — pain, fertility, or both — and avoid unnecessary delays in trying for pregnancy when that is the goal.
