As we mentioned in previous articles during the last stage of the menstrual cycle normally a layer of endometriosis lining in the inside of the uterus is expelled, known as menstruation blood but instead some of the endometriosis tissues growing somewhere in the body causing endometriosis. Endometriosis also reacts to hormonal signals of the monthly menstrual cycle by building up tissue, breaking it, and eliminating it through the menstrual period. In this article, we will discuss how the pill is used in treating endometriosis.
