Background & Aims: Most pregnant women suffer from anemia during pregnancy ,which is considered a health problem, as it affects large numbers of people of all ages. Pregnant women are among the age groups most vulnerable to anemia due to the increased amount of blood produced by the body to help provide nutrition for the fetus. These disorders contribute to pregnant women feeling several diseases, including fatigue, exhaustion ,constant headaches and other symptoms.Anemia is widespread in Iraq and one of the best public causes of anemia is the absence of nutrients such as calcium and iron. Iron plays a role in the production of hemoglobin resulting from malnutrition, repeated childbirth and short intervals between births.Methods:To determine the prevalence of anemia in Maysan province, this study conducted a survey of 80 samples of pregnants aged (25-35)years, divided into three groups , as follow : The first group  includes 40 samples of pregnant women who are not anemic , ranging in age from (25-35)years.The second group includes 20 samples (women with anemia) whose ages ranged from (25-30) years and third groups.Results::The results included hematological and chemical variables measured in the blood of pregnant women.The reason for the spread of anemia in pregnant women is a defect in the production of hemoglobin ,red blood cells,white blood cells , and platelets , in addition to some biochemical parameters. This is consistent with other studies in other countries around the world . In light of the results obtained , recommendations were developed to reduce and prevent this disease.
