Hello and welcome to Chat Doctor, Extreme tiredness is most commonly caused by anemia. Anemia is not a disease, but it is an indication of an underlying disorder. Anemia is investigated by investigations like complete hologram and red cell parameters. After these investigations, it is important to get iron profile done. Iron deficiency is the most common cause of anemia, thus, its complete iron profile is required which includes serum iron, serum ferritin, total iron binding capacity and saturation. If serum iron/ ferritin is reduced, iron supplements have to be started. Thanks and take care Chat Doctor.
