What are the symptoms of iron-deficiency anemia?

Iron-deficiency anemia occurs when there is not enough iron in the body to produce adequate hemoglobin, the protein in red blood cells that carries oxygen. The symptoms associated with this condition are primarily due to decreased oxygen delivery to tissues. Fatigue and weakness are common because the body does not receive sufficient oxygen to perform basic functions efficiently. Pale skin results from reduced blood flow or a lower number of red blood cells, while shortness of breath can occur during physical activity or even at rest as the body struggles to meet its oxygen needs. These symptoms collectively characterize iron-deficiency anemia and reflect its impact on overall health and energy levels.
