Painful menstruation is referred to as dysmenorrhea in the medical community. There are two types of dysmenorrhea: primary and secondary.
Primary dysmenorrhea is most common and is the natural (though unpleasant) cramping sensation stimulated by hormone fluctuations. Though it’s not desirable, it’s nothing to be too concerned about.
Secondary dysmenorrhea, on the other hand, is an abnormal condition that causes severe menstrual pain due to an underlying health issue. Common causes of secondary dysmenorrhea include adenomyosis and endometriosis.
While menstrual cramps may seem like a curse, there’s actually a pretty simple explanation for them. Each month, our bodies go through a variety of hormone changes that prepare us for pregnancy. If pregnancy doesn’t occur, our body gets the signal to ditch its lush uterine lining (endometrium).
To shed the lining, the uterus begins to contract and relax to loosen the endometrium’s hold on the interior of the uterus. As this happens, the endometrium begins to detach and flow out of the body a little bit at a time.
It’s believed that an increase in hormones called prostaglandins is most likely to blame for the pain and cramping some women experience when the uterine lining is expelled. Higher levels of prostaglandins in some women are associated with more intense menstrual pain because they can cause powerful muscle spasms in the uterus.
However, prostaglandins may not cause every instance of menstrual cramping. Unfortunately, it isn’t fully understood why some women experience more painful periods than others. Some women have painful menstrual cramps every month with no clear cause, while others may experience severe pain due to underlying medical conditions such as pelvic inflammatory disease, premenstrual syndrome, uterine fibroids, or endometriosis.
