The four stages of Endometriosis

stage1-endometriosis-internalsymptoms
stage2-endometriosis-internalsymptoms

Stage one

This is the earliest stage of manifestation. "Endometrial tissue infiltrates the peritoneum", or in plain speech, tissue similar to the uterus lining known as endometrium, grows outside of the womb.

There may be small growths or areas of tissue damage and minimal scarring. Here, the tissue growth hasn’t yet infiltrated any other organs.

Despite being medically labeled as 'minimal', this doesn't always reflect the severity of its symptoms as it can vary.

Stage two

Stage two shows progression of the condition. Endometrial tissue starts to extends deeper into the layers of pelvic organs, showing more signs of inflammation, scarring and small ahesions.

The presence of ovarian cysts at this stage raises the risk of rupture, and it increases the chance of endometriosis spreading within the pelvic cavity. 

Despite being medically labeled as 'mild', this doesn't always reflect the severity of the symptoms as it can vary.

Stage three

Stage three shows a notable presence of deep implants or 'growths' and one or both ovaries may exhibit small cysts and adhesions.

This can affect the organs located within the pelvic cavity, and may impact the ovaries, rectum, and uterus, leading to substantial distortions in the pelvic region.

Despite being medically labeled as 'moderate', this doesn't always reflect the severity of its symptoms as it can vary.

Stage four

Stage four shows widespread and deeply infiltrating implants or growths, extensive scarring, and adhesions or 'obliteration of the womb'.

The tissue growth deeply infiltrates the pelvic organs and may grow outside the pelvic area, e.g. on organs such as the bowels, appendix, diaphragm, heart, and lungs.

Despite being medically labeled as 'moderate', this doesn't always reflect the severity of its symptoms as it can vary.
