Diabetes mellitus is a metabolic chronic disease, with global estimation increase in patient (around 100 million in 2030).The aim of the current study is to investigate vitamin D, C-reactive protein and estradiol levels in pre and postmenopausal Iraqi women with type 2 diabetes (T2MD).A total of 176 female distributed into two groups: the first included 90 women withT2MD (43 pre and 47 post-menopausal); the second group included 86 healthy subjects (41 pre and 45 postmenopausal) considered as control. This study has shown that women in premenopausal (20-40 years) had highly significant difference in the estradiol and vitamin D levels in diabetes subjects (62.192 ± 17.643pg/ml, 10.522 ± 1.958ng/ml) compared with healthy (131.793 ± 18.003, 28.573 ± 12.302) respectively, also significant difference in CRP level (8.485 ± 4.318) was indicated compared with non-diabetes (4.811 ± 3.778pg/ml) and there was significant increase in body mass index in diabetes compared to healthy. Postmenopausal female results showed significant difference inestradiol and vitamin D which reached (44.82407 ± 19.626pg/ml, 9.830 ± 5.845ng/ml) compared with healthy (122.531 ± 15.738pg/ml, 25.492 ± 10.967ng/ml) respectively, body mass index showed significant increase also, however, there was no difference in CRP level. A significant correlation was observed between CRP and estradiol level in premenopausal women, however, there was no significant in others factors.the search found high correlation of CRP and estrogen in type 2 diabetes compared with healthy women.
