What is Rectal Endometriosis? (Definition/Background Information)

• Rectal Endometriosis is a type of endometriosis where endometrial-like tissue, similar to the tissue lining the uterus, grows on or inside the rectum. This abnormal growth can lead to pain in the rectum, bowel symptoms, and discomfort
• Women in their young to middle adulthood are higher prone to the development of this condition. The risk factors may include a family history of endometriosis and nulliparity. The exact cause of Rectal Endometriosis is not fully understood
• Pelvic exams and imaging studies may be used in the diagnosis of Endometriosis of the Rectum. Following a diagnosis, the condition may be treated using pain medications and surgical interventions as needed. The prognosis is typically improved following early recognition and adequate treatment of the condition

Who gets Rectal Endometriosis? (Age and Sex Distribution)

• Rectal Endometriosis primarily affects women of reproductive age, typically between 25 and 40 years
• It is more commonly seen in women diagnosed with endometriosis in other locations
• The condition is observed worldwide, and all racial and ethnic groups are generally at risk

What are the Risk Factors for Rectal Endometriosis? (Predisposing Factors)

The risk factors for Rectal Endometriosis may include:

• A history of endometriosis in other pelvic organs
• Family history of endometriosis
• Never having given birth (nulliparity)

It is important to note that having a risk factor does not mean that one will get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. Some risk factors are more important than others.

Also, not having a risk factor does not mean that an individual will not get the condition. It is always important to discuss the effect of risk factors with your healthcare provider.

What are the Causes of Rectal Endometriosis? (Etiology)
