Patients diagnosed with severe iron deficiency need iron infusion This is an alternative therapy that can be used when oral iron supplements or intramuscular iron supplementation are not available Iron deficiency occurs when the body does not produce enough red blood cells to make up for the loss Chemotherapy, chronic inflammatory bowel disease and renal failure are some diseases or conditions requiring iron infusion Usually in the hospital to receive iron infusion Before the treatment, the medical staff usually inject about 25 mg iron intravenously to observe vital signs and adverse reactions Iron glucuronate, iron dextran and iron sucrose complexes are infusion products diluted with normal saline Depending on the degree of anemia and the prescription, iron infusion treatment will last for 3-8 hours In patients receiving iron infusion, allergic reaction is the main problem The reaction may be local urticaria or rash, but more serious symptoms such as dyspnea, dysphagia and chest pain may also occur The common side effects of iron infusion include dizziness, blushing, headache, metallic taste in mouth, etc Some patients also experience flu like symptoms for two or three days Chemotherapy usually impairs red blood cells or the ability of bone marrow to produce substitutes Patients with inflammatory bowel disease, including Crohn's disease or ulcerative colitis, usually have internal bleeding, resulting in a reduction in the number of red blood cells End stage renal disease (ESRD) is one of the common reasons that patients need iron infusion The diseased kidney does not secrete enough erythropoietin, a hormone that stimulates erythropoiesis in the bone marrow Doctors also believe that the body's failure to remove waste effectively can lead to uremia, which can also lead to bone marrow loss Doctors usually diagnose iron deficiency when hematocrit and hemoglobin levels are below acceptable levels Depending on the laboratory standard, the average hematocrit level is 33% to 36% The average level of hemoglobin is 11 to 13 grams per deciliter, indicating the amount of ferritin in red blood cells Iron levels in women's blood range from 40-150 micrograms per deciliter to 50-160 micrograms in men.
