Unusual tiredness

One of the most prevalent symptoms of iron deficiency anemia is severe tiredness. Even if they haven't been diagnosed with an iron deficiency, this symptom is frequent in people who simply don't have enough iron.

This fatigue is caused by a shortage of iron in your body, which is required for the production of hemoglobin, a protein that helps in the transport of oxygen throughout your body. Less oxygen reaches your tissues and muscles if you don't have enough hemoglobin, depriving them of energy. In order to move more oxygen-rich blood around your body, your heart must work harder, which might make you tired. Because tiredness is commonly regarded as a normal part of modern life, diagnosing an iron shortage based solely on this symptom is difficult. However, tiredness caused by the iron deficiency may be followed by weakness, irritability, or difficulty concentrating.
