Nutritional anemia is a condition where the body lacks enough healthy red blood cells due to insufficient nutrients, particularly iron, vitamin B12, or folate. These nutrients are essential for producing hemoglobin, the protein in red blood cells that carries oxygen throughout the body. When levels are low, individuals may experience fatigue, weakness, and pale skin. This type of anemia is often caused by poor dietary choices, malabsorption issues, or increased nutritional needs, such as during pregnancy. Treatment typically involves dietary changes, supplements, or addressing underlying health issues to restore nutrient levels and improve overall health.
