Anemia is a common condition in women of childbearing age which is associated with wide spread hyperplastic processes in the uterus (leiomyomas, etc.) and abnormal and/ or abundant uterine bleeding (AUB). Our study has considered the main causes of bleeding and the therapy aimed on limiting the amount of blood loss, as well as preoperative treatment of iron deficiency in women with uterine leiomyomas, planning for pregnancy.The combination of anemia with other abnormalities in the woman's health status is associated with complications during pregnancy such as premature births, the birth of small children and failure of the formation of neural tube in iron deficiency and hypoxia. During the treatment of iron deficiency anemia (IDA) with saline iron, we noted severity and pain in the stomach in 11.9% of patients, nausea in 13.1%, constipation in 21.4%, and diarrhea in 7.1% of women. Such complications did not occur while treating with ferric iron. The use of drugs Iron III hydroxide polymaltozate in women after the end of lactation resulted in normalization of the blood hemoglobin within 30 days and the number of erythrocytes and of serum ferritin by the 90th day.
