Anemia is a medical condition characterized by a deficiency in the number or quality of red blood cells in the body, leading to a decreased ability to transport oxygen to tissues and organs. This can result in symptoms such as fatigue, weakness, and shortness of breath. Anemia can be caused by various factors, including nutritional deficiencies, chronic diseases, and genetic disorders. Researchers in the field of anemia study the causes, prevention, diagnosis, and treatment of this condition in order to improve outcomes for patients. This may involve investigating new therapies, improving diagnostic methods, and understanding the underlying mechanisms of anemia.
