Causes of Endometriosis
The immune system normally destroys any endometrial cells outside of
the uterus. But women with endometriosis may have a problem with the
immune system that may impair this process.
Endometrial tissue cells travel out of the uterus through blood or
lymph vessels, and then start growing in the new locations where
they''re deposited. Yet another theory suggests that some girls are born
with "misplaced" cells that can turn into endometrial implants later in
life. Scientists continue to research the condition to help doctors
fully understand and treat it.
Environment: Based on animal studies, some researchers have linked
endometriosis to the pollutant dioxin. Dioxin comes from many places
including the wood and plastics industries, animal fat, cigarette
smoke, and exhaust from gasoline and diesel engines.
Cells in the abdomen and pelvis, which are closely related to the cells
of the reproductive system, may change into endometrial cells.
Genetic susceptibility: Studies indicate that some women are
genetically predisposed to developing endometriosis. According to
researchers from the University of Queensland, endometriosis runs in
families, which means the genetic susceptibility is inherited.
