Dysmenorrhea is one of the most common gynaecological complaints in young women who visit to clinicians. The etiology and pathophysiology of dysmenorrhea have not been fully elucidated. Although in literature obesity has also been considered as one of the factors for dysmennorhea, much work has not been done to study this association. In the present study, effort was put to evaluate the prevalence of dysmenorrhea and obesity among young girls and further see if any correlation exists among them. To meet the goal, 1400 adolescent and young girls (17-22 years.) of different educational institutes were recruited. Their body measurements were taken and details regarding their menstrual status like the age at menarche, number of days of blood flow and how many days they suffer from pain, etc. were noted down. The prevalence of obesity and dysmenorrhea was assessed. The lipid profile of 200 selected girls (100 with dysmennorhea and 100 normal) was done. The girls with dysmenorrhea were observed having higher rate of obesity as compared to normal girls but the differences were statistically not significant. Similarly, the status of lipid profile was bad among girls with dysmenorrhea but the differences between normal girls and dysmennorheal girls were statistically significant. The results reflect that obesity may be one of the factors but not the culprit behind dysmenorrhea. Research at biochemical levels like the study at the levels of prostaglandins is needed along with other environmental factors before coming to some conclusion.
