2. Excessive Bleeding During Menstruation
One dangerous symptom of endometriosis is excessive bleeding during menstruation. Someone who’s suffering from this condition might also experience unusually long periods that last longer than the average 7-days. Excessive bleeding can cause low levels of iron which leads to fatigue, hair loss, and anemia. For women who experience heavy or long menstruation, iron supplements or iron intravenous injections may be necessary.
“When you get your period, the endometrial growths react to menstrual hormones from your ovaries the same way the lining of your uterus does, so they grow and bleed, too. As endometrial growths get bigger over time, they can bleed even more,” writes Self. The Mayo Clinic points out that endometriosis can develop early on in a woman’s reproductive stages so she might not know her period is unusually heavy because that’s all she’s used to.
