Is this trial a fit for you?

Likely a good fit

Women aged 18-45 with a confirmed endometriosis diagnosis and irritable bowel-like symptoms who are on or off hormonal treatment and have a BMI 18.5–24.9.

Probably not a fit

Individuals without gut-related symptoms or whose symptoms are not diet-responsive may not experience benefit.

What this trial studies

This interventional study compares a structured FODMAP dietary regimen to a standard treatment plan without specific dietary guidance in women with surgically or diagnostically confirmed endometriosis and irritable bowel-like symptoms. The aim is to see if reducing certain fermentable carbohydrates lessens pelvic pain and related symptoms. Participants are 18 to 45 years old, with a BMI between 18.5 and 24.9, and are either on hormonal therapy or not. The trial is led by Fondazione IRCCS Ca' Granda and is based in Milan, Italy. Outcomes focus on pain, quality of life, and sexual function, reflecting a holistic view of endometriosis impact.

Why it matters

Potential benefit: If successful, participants may experience reduced pain and improved daily functioning and sexual health related to endometriosis.

How similar studies have gone: Previous data in IBS and related conditions suggest dietary FODMAP modifications can alleviate symptoms, but effects in endometriosis with GI symptoms are less established.
