Tell me something about what is the causes of having dysmenorrhea??

about having a montly period..

"To understand dysmenorrhea, it's important to understand how the menstrual cycle works. Each month, the lining of the uterus, the endometrium, thickens to prepare for the egg that is released by the fallopian tubes. If the woman does not become pregnant during that cycle, then most of the endometrium is shed and bleeding occurs. The blood flows from the uterus, through the cervical canal, and out through the vagina. Primary dysmenorrhea occurs when the uterus contracts because the blood supply to the endometrium is reduced. This pain occurs only during a menstrual cycle where an egg is released. If the cervical canal is narrow, the pain may be worse as the endometrial tissue passes through the cervix. Pain can also be caused by a uterus that tilts backward instead of forward, low levels of physical activity, and emotional stress. Secondary dysmenorrhea can be caused by the growth of uterine tissue outside the uterus, called endometriosis; non-cancerous growths of muscle and fibrous tissue in the uterus, called fibroid tumors; the non-cancerous growth of the uterine lining in the muscular wall of the uterus, called adenomyosis; inflammation of the fallopian tubes; and the growth of scar tissue, or adhesions, between organs."

"The cause of dysmenorrhea depends on whether the condition is primary or secondary. In general, women with primary dysmenorrhea experience abnormal uterine contractions as a result of a chemical imbalance in the body (particularly prostaglandin and arachidonic acid - both chemicals which control the contractions of the uterus). Secondary dysmenorrhea is caused by other medical conditions, most often endometriosis (a condition in which tissue that looks and acts like endometrial tissue becomes implanted within the wall of the uterus or outside the uterus, usually on other reproductive organs inside the pelvis or in the abdominal cavity - often resulting in internal bleeding, infection, and pelvic pain). Other possible causes of secondary dysmenorrhea include the following:

* pelvic inflammatory disease (PID)
* uterine fibroids
* abnormal pregnancy (i.e., miscarriage, ectopic)
* infection, tumors, or polyps in the pelvic cavity."
