What stage of endometriosis is classified as 'severe'?

The classification of endometriosis stages is based on the extent and severity of the disease as observed during surgical evaluation and the corresponding symptoms and findings. Stage IV is recognized as the severe stage, which is characterized by the presence of extensive endometrial tissue, deep infiltrating lesions, and the involvement of pelvic organs such as the ovaries and bowel.

In Stage IV, patients may exhibit significant symptoms, including severe pelvic pain, infertility, and potential complications related to organ damage. This stage also often shows the formation of adhesions, which can cause complications and influence treatment options.

Understanding the characteristics of each stage is crucial for diagnosis and treatment. In contrast, the earlier stages, like Stage I and II, reflect minimal to mild endometriosis with less extensive lesions, while Stage III indicates moderate disease, often with some deeper infiltrating lesions but not to the extent seen in Stage IV. Recognizing the severity of the disease is essential to providing appropriate management and care for individuals affected by endometriosis.
