Anaemia is a condition that occurs when the body does not have enough red blood cells or hemoglobin, the protein in red blood cells that carries oxygen. This can result in a lack of oxygen in the body’s tissues and organs, leading to symptoms such as fatigue, weakness, and shortness of breath. There are many different types of anemia, including iron-deficiency anemia, which is the most common type and occurs when the body does not have enough iron to produce hemoglobin. Other types of anemia can be caused by genetics, chronic disease, or certain medications. Treatment for anemia depends on the underlying cause but may include dietary changes, iron supplements, or blood transfusions.
