Can a bleeding ulcer be the cause of microcytic hypochromic anemia?

Yes.: A bleeding ulcer could cause iron deficiency anemia (low red blood cell count). If the bleeding is severe and persists for a while, red blood cells will be small (microcytic) and have relatively less oxygen-carrying hemoglobin (hypochromic). Thanks to m. Dinapoli, med student.

Yes: With a bleeding ulcer, you tend to bleed slowly and chronically, eventually causing iron deficiency, which causes the new red blood cells to be created in response to the developing anemia to be small, i.e. Microcytic. Sometimes this type of anemia is the first hint that an ulcer exists, although any chronic slow blood loss will cause this type of anemia.
