Impact of Dietary Guidance and Probiotics in the Treatment of Endometriosis and Irritable Bowel Syndrome in Women

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Endometriosis, Bowels Irritable

In brief

Patients with endometriosis are 2 to 3 times more likely to develop Irritable Bowel Syndrome (IBS) than women without the condition. IBS presents symptoms similar to those of intestinal and deep EDT, leading to diagnostic errors and delays in identifying such comorbidities. Diets have shown positive effects on symptoms in women with both conditions, supporting the theory of a similar pathophysiology. The investigators goal is to examine how dietary practices and probiotic use affect chronic pelvic pain in patients with both comorbidities.
