Which symptom is most commonly associated with endometriosis?

Pelvic pain is the most commonly associated symptom of endometriosis. Individuals with this condition often experience chronic pelvic pain, which can occur during menstruation, as well as during intercourse, bowel movements, and urination. The pain arises due to the presence of endometrial-like tissue outside the uterus, leading to inflammation and adhesions in the pelvic region.

While infertility, heavy menstrual bleeding, and irregular cycles can also be associated with endometriosis, they are not as universally defining of the condition as pelvic pain. Many women with endometriosis report significant chronic pain, which can severely impact their quality of life, making it the hallmark symptom that often prompts diagnosis and treatment.
