The complex relationship between body mass index and endometriosis

There is an inverse relationship between endometriosis and a women’s body mass index. To date, the precise mechanisms and aetiological basis linking body mass index with endometriosis remain unknown. Although an increased incidence of endometriosis is observed in women with low body mass indices; endometriosis is associated with conditions common to obesity (hypercholesterolemia, hypertension and coronary heart disease). In the context of endometriosis, further research is necessary in women with surgically confirmed disease to improve clinical advice and patient outcomes.
