I am dizzy,tired,uninterested in anything,weak,im a shiftworker and my productivity is down. what could be wrong. have been diagnosed with anemia.

Anemia: All of the above symptoms could be due to anemia. The key is to find out what the cause of the anemia is. Certainly your monthly losses could contribute, but it is important to be sure that there is no G.I. bleeding as an additional cause. Once you are aware of the cause, treatment for the anemia can be started, perhaps with iron or transfusions if necessary. Hope that helps.
