Staging depends on certain factors. These include:
- Number, size, and site of implants
- Presence and extent of adhesions
- Involvement of other pelvic organs
The stage may not match the pain you feel. Even early stages can cause a large amount of pain.
The 4 stages are listed below and are based on a complex scoring system.
I - Minimal
II - Mild
III - Moderate
IV - Severe
