What Is Endometriosis, and How Do I Know?

The short answer

What is endometriosis, and how would you know if you have it? Endometriosis is when tissue similar to the lining of your uterus grows in places it shouldn't, and the biggest clue is period pain that's severe enough to disrupt your life. Let me explain.

Tissue like the uterine lining grows where it shouldn't

It bleeds each cycle but has no way out, causing inflammation

Each month, the lining inside your uterus builds up and sheds as your period. With endometriosis, similar tissue grows outside the uterus, on the ovaries, fallopian tubes, or elsewhere in the pelvis. It still responds to your hormones, so it swells and bleeds each cycle, but it has no way to leave the body. That causes inflammation, pain, and over time, scar tissue.

Main sign: period pain that stops your life

The main sign is intense period pain. Not the normal kind, but pain that stops you from working, studying, or sleeping. Other signs include pelvic pain between periods, pain during or after sex, very heavy periods, and pain when you pee or poop, especially during your period.

Also: deep fatigue, 'endo belly', trouble conceiving

It can also bring deep fatigue, bloating sometimes called endo belly, and trouble getting pregnant. Tracking your pain and symptoms across your cycle in an app like PinkyBloom can reveal a pattern that helps your doctor.

Severe period pain is NOT normal, push for answers

Here's something important: endometriosis is often missed for years, partly because severe period pain gets brushed off as normal. It is not normal to have pain that takes over your life. If that's you, push for answers.

A doctor can diagnose it, and there are real treatments

A doctor can explore it with an exam, imaging, and sometimes a small keyhole surgery to confirm. There are real treatments, both for the pain and for fertility, so getting diagnosed is worth it.
