The lecturer Dr. (Ziad Tariq Habib), the head of the Chemistry Department at the College of Education for Pure Sciences, published a scientific research entitled (Assessing the Link between Vitamin D Levels and Miscarriage Risk in Women), in an international journal (Asian Journal of Medicine and Health). The research aimed to find out that the issue of miscarriage, sometimes known as missed abortion, is a contemporary concern in the field of obstetrics and gynecology. This condition is characterized by a set of clinical symptoms, one of which is the inability of the fetus to survive. Through its metabolism of vitamin D 1.25 (OH), vitamin D plays an important role in promoting women’s reproductive health. The research also included 180 women who survived miscarriage; and only 43 women with unexplained miscarriage. They were treated in private clinics in Karbala Governorate during the period from May to August 2024, and their ages ranged between (17-43) years. The confident diagnosis was confirmed by examination by gynecologists. Of the 180 women who had miscarriages, only 43 were included in the current study. The study evaluated infectious agents and other autoimmune disorders in all women who had miscarriages. The study found an association between vitamin D deficiency and idiopathic miscarriage in women. Patients who had miscarried were evaluated to rule out all other possible causes of miscarriage, including age, body mass index, hypertension, endometrial abnormalities, and smoking.
