what makes you tired all the time
Anemia can happen when your body isnât producing enough red blood cells or the red blood cells donât contain enough iron-rich hemoglobin, says Amy L. Doneen, ARNP, medical director of the Heart Attack & Stroke Prevention Center. That lack of oxygen-rich blood in your body can make you feel tired and weak. While iron deficiency is the most common cause of anemia, other causes include heavy periods, sluggish bone marrow, vitamin B12 deficiency or a lack of folate in the diet, says Dr. Rindfleisch.
