What are the different stages of endometriosis and their symptoms?

Endometriosis is a condition where tissue similar to the lining inside the uterus grows outside of it. This condition is categorized into four stages based on the extent and depth of endometrial growth.

1. Stage 1 (Minimal): This stage involves small lesions and shallow endometrial implants. Symptoms may be mild or even absent.

2. Stage 2 (Mild): There are more lesions than in Stage 1, and they are deeper. Symptoms may include mild pelvic pain.

3. Stage 3 (Moderate): This stage features many deep implants, small cysts on one or both ovaries, and thin adhesions. Pain can be more noticeable, and fertility issues may begin to appear.

4. Stage 4 (Severe): The most advanced stage, characterized by many deep implants, large cysts on the ovaries, and thick adhesions. Symptoms can include severe pain and significant fertility problems.

The symptoms of endometriosis can vary widely and do not always correlate with the stage. Pain is a common symptom, but its intensity may not match the severity of the disease. Some people with severe endometriosis experience little pain, while others with mild endometriosis may have intense pain.
