Endometriosis affects everyone differently—but many people don’t realize it’s actually classified into four stages. These stages help doctors understand how much tissue is present, where it’s located, and how it might affect your symptoms or fertility.
But here’s the truth: The stage of your endometriosis doesn’t always match the intensity of your pain. Some women with stage 1 are in daily agony. Others with stage 4 may feel less pain. That’s why knowing your stage is helpful—but it’s only part of the picture.
