What is Anemia its signs and symptoms

What is Anemia:
Anemia extracted from the greek word meaning “without blood,” is defined as a qualitative or quantitative deficiency of hemoglobin, a molecule inside red blood cells (RBCs).anemia leads to hypoxia (lack of oxygen) in organs.
Signs and Symptoms of Anemia:
Anemia goes undetected in many people, and symptoms can be small and vague. Most commonly, people with anemia report a feeling of weakness or fatigue in general or during exercise, general malaise and sometimes poor concentration. People with more severe anemia often report dyspnea (shortness of breath) on exertion. Very severe anemia prompts the body to compensate by increasing cardiac output, leading to palpitations and sweatiness, and to heart failure.
Chronic anemia may result in behavioral disturbances in children as a direct result of impaired neurological development in infants, and reduced scholastic performance in children of school age.
