Print Menstrual Cramps By Andrea Chisholm, MD Updated September 08, 2016 As any woman who has been through labor can tell you, the uterus is a strong muscle capable of very intense contractions. While the normal changes that cause you to bleed each month also cause the uterus to contract, fortunately, theses contractions—menstrual cramps—are only a fraction as strong as they are during labor. That said, the level of discomfort some women experience can still be hard to cope with. What Exactly Are Menstrual Cramps?Menstrual cramps are the result of hormone-induced muscular contractions of the uterus. Your uterus is made up of two main layers. The outer muscular layer, the myometrium, is composed of smooth muscle cells. The inner layer, the endometrium, responds to changes in your hormone levels. The endometrium builds up in the first half of your menstrual cycle, preparing for pregnancy. Article Attention Girls: You Don't Have to Let Painful Periods Run Your Life Article When You Should See Your Doctor for Menstrual Cramps When pregnancy doesn't happen, hormone changes cause substances known as prostaglandins to be released from the endometrium. These cause the muscle of your uterus, or the myometrium, to contract, resulting in the shedding of the endometrial lining. This shed lining is a big part of your menstrual flow. This is a normal body function, and most women will have some mild discomfort every month during the beginning of their period because of it.Three Things to Know About Menstrual CrampsNormal Can Still Be a ProblemYes, menstrual cramps are a normal part of your menstrual cycle. But that doesn't mean they are not a problem for you. Sometimes these contractions are intense enough to interfere with the usual blood flow to your uterus. This decreased blood flow triggers a pain response. This pain associated with your period is called dysmenorrhea. It is often significant enough to interrupt your usual activities, including school or work. Dysmenorrhea can be mild and easily treated with lifestyle changes or over-the-counter pain medication. Dysmenorrhea can also be severe, requiring multiple medications or even surgery.Not All Menstrual Cramps Are the SameThere are two types of dysmenorrhea. In general, the different types are based on when the cramps started and what is causing them.Primary Dysmenorrhea: For some women, their periods have been painful from the very start. If you have always had painful periods, it is likely that your menstrual cramps are caused by an exaggerated response to your body's normal changes. Specifically, it is thought that women with primary dysmenorrhea have increased amounts of prostaglandins, the substances that causes the uterus to contract. Article What Does Mittelschmerz Mean?
