What are the signs of iron deficiency?

Low iron levels inhibit the production of hemoglobin, resulting in reduced red blood cells. When the body can’t supply enough red blood cells to meet its demands, it manifests as anemia, which affects an estimated two billion people around the globe. Symptoms include tiredness, fatigue, pale skin, shortness of breath, headaches, and dizziness. These initial symptoms of deficiency can go unnoticed, but if left untreated, anemia can have serious repercussions, including impaired cognitive function, disturbances in the digestive system, and impaired immunity. Pregnant women, young children and frequent blood donors are at a much higher risk of iron deficiency.
