Dysmenorrhea.
Dysmenorrhea is one of the most common gynecologic complaints of young women, affecting approximately half of menstruating females. Although most patients have primary dysmenorrhea, which although creating much discomfort does not lead to significant physical problems, it is very important to rule out secondary dysmenorrhea to prevent problems with health and fertility. Primary dysmenorrhea is seen only in ovulatory cycles, usually developing within 6 to 12 months of menarche and is characterized by lower midabdominal colicky pain that may radiate to the back and upper thighs. The pain of primary dysmenorrhea starts with the onset of menstrual flow or a few hours following onset and may last for a few hours up to 2 days. The pain of secondary dysmenorrhea usually begins several days before the start of menstrual flow and may be present during much of the menstrual cycle. Pain that occurs with the first menses or after the age of 25 or is associated with anovulatory cycles is more likely to be secondary dysmenorrhea. The causes of secondary dysmenorrhea, such as endometriosis, adenomyosis, complications of intrauterine devices, and congenital abnormalities, will often be associated with abnormalities noted on pelvic examination, and whenever dysmenorrheic patients have any abnormalities, further evaluation is necessary.
