Persistent fatigue despite sleep signals possible iron deficiency

Some people experience a persistent feeling of fatigue and tiredness, which may be a sign of iron deficiency in the body, especially when accompanied by symptoms such as pallor, dizziness, headaches, and shortness of breath. Iron deficiency is a major cause of anemia resulting from low hemoglobin levels, which is responsible for transporting oxygen to the body's tissues. Iron deficiency is diagnosed through blood tests such as hemoglobin and ferritin levels. It is important to consult a doctor before taking iron supplements to avoid side effects and ensure appropriate treatment. Persistent fatigue combined with other symptoms warrants testing to confirm the deficiency and identify its causes, as exhaustion may be due to various health factors unrelated to iron deficiency.
