Endometriosis can cause irregular periods.
More Info: Endometriosis, which is the growth of cells from the womb lining in other parts of the body, can lead to irregular periods, pain, and difficulty becoming pregnant.
During a woman’s menstrual cycle, hormones cause the lining of the uterus to build up tissue and blood, which is shed during the menstrual cycle.
Endometriosis occurs when this lining, called the endometrium, begins to grow outside of the uterus rather than shedding. The endometriosis growths can attach to organs in the pelvic area such as the ovaries, fallopian tubes, and bowels. The growths, which are buildup of tissue and blood, can bleed in between menstrual cycles causing irregular periods. The trapped blood from these growths can also cause cysts in the ovaries and block fallopian tubes.
