Anemia is a condition where the body lacks enough healthy red blood cells to carry adequate oxygen to its tissues. This can lead to symptoms such as fatigue, weakness, and pale skin. Anemia can result from various factors, including nutritional deficiencies, chronic diseases, or genetic disorders. There are different types of anemia, with iron-deficiency anemia being the most common. This type occurs when the body doesn't have enough iron to produce hemoglobin, the protein in red blood cells that binds oxygen. Treatment often involves dietary changes, supplements, or addressing underlying health issues.
