Endometriosis has 4 stages. Your health care provider can use the picture to the right to show you the size and location of your implants. The stages are described below.
Stages of endometriosis
The stages are ranked as follows: Minimal (I), Mild (II), Moderate (III), or Severe (IV). Staging depends on certain factors. These include the number, size, and site of the implants. The stage also depends on the extent of the adhesions and whether other pelvic organs are involved. The severity of your disease may not match the pain you feel. Even mild endometriosis can cause a lot of pain.
Minimal: Shallow implants on ovary.
Mild: Shallow implants on pelvic lining and ovary. Light adhesions.
Moderate: Deep implants on pelvic lining and ovary. Dense adhesions.
Severe: Deep implants on ovaries and pelvic lining. Dense adhesions on ovaries, tubes, and bowel.
