"This trial will test if adding Hyperbaric Oxygen Therapy (HBOT) to standard treatments is more effective in treating endometriosis pain than standard treatments alone. Endometriosis is a condition

Who is the study for?
The HEROES Trial is for women suffering from endometriosis, a condition causing pelvic pain and infertility due to tissue growth outside the uterus. Participants should be seeking additional treatment beyond standard options, which may have limited effectiveness or long wait times for surgery.
What is being tested?
This trial investigates whether Hyperbaric Oxygen Therapy (HBOT), involving breathing pure oxygen in a pressurized chamber, can more effectively reduce endometriosis-related pain when combined with standard treatments compared to standard treatments alone.
What are the potential side effects?
Potential side effects of HBOT include ear pressure changes leading to discomfort or temporary hearing loss, fatigue after sessions, and in rare cases, oxygen toxicity which could cause lung issues or seizures.
