Anemia is a medical condition characterized by a deficiency in the number or quality of red blood cells or hemoglobin in the blood, leading to reduced oxygen transport to tissues throughout the body. This can result in symptoms such as fatigue, weakness, pale skin, shortness of breath, and dizziness. Anemia can be caused by various factors, including nutritional deficiencies (such as iron, vitamin B12, or folate), chronic diseases, bone marrow disorders, and genetic conditions like sickle cell anemia. Diagnosis typically involves blood tests, and treatment varies based on the underlying cause, ranging from dietary changes and supplements to more complex medical interventions.
