Iron deficiency anemia is a condition characterized by a lack of sufficient iron in the body, which is necessary for the production of hemoglobin, a protein in red blood cells that helps carry oxygen to tissues and organs. Without enough iron, the body is unable to make an adequate amount of red blood cells, leading to symptoms such as fatigue, weakness, pale skin, shortness of breath, dizziness, cold hands and feet, and headache. Iron deficiency anemia can be caused by a variety of factors, including inadequate dietary intake of iron, chronic blood loss (such as menstrual bleeding or gastrointestinal bleeding), and conditions that interfere with iron absorption. Treatment typically involves increasing iron intake through diet or supplements, and addressing any underlying causes of the deficiency.
