  • Excessive Bleeding: Excessive bleeding can be one of the reasons for anemia. This excessive bleeding can be due various reasons like heavy menstrual bleeding, wounds, gastrointestinal ulcers or cancers such as cancer of colon can ooze out blood slowly which can result in anemia.
  • Deficiency Of Iron: Iron is An important constituent of RBC. If there is a deficiency of this in the body due to any reason then it can result anemia. Hence iron is very necessary for the blood.
  • Kidney Disease: Actually production of RBCs depends indirectly on kidneys. It because kidneys produce a hormone called Erythropoietin which helps bone marrow in the production of RBCs. The people who suffer from kidney problems for a longer duration diminishes the production of this hormone thus diminish the production of RBCs also. Hence, causing anemia.
  • Pregnancy: During pregnancy a lot of retention of water is there which dilutes the blood. This dilution can cause anemia.
  • Poor Nutrition: Body requires lot of vitamins and minerals for the production of RBC. Similarly, iron, vitamin B12 and foliates are required for producing hemoglobin. Any kind of deficiency in any of them can result in Anemia.
  • Diseases/ Conditions: Some diseases or conditions like HIV/AIDS, Crohn’s disease, rheumatoid arthritis can cause hindrances in producing red blood cells. Similarly, disease of malaria can cause severe anemia. It is because a protein is produced by the immune cells during malaria which triggers severe anemia.

  • Excessive loss of blood which can be due to stomach ulcers, Hemorrhoids, stomach inflammation, cancer, child birth, menstruation, surgery, trauma such as car accidents etc.
  • Excessive destruction of red blood cells which can be due to toxins, infections, immune reactions, some medical procedures like heart-lung bypass, hemodialysis etc.
  • Deficiency in production of red blood cells due to some conditions like sickle cell anemia, vitamin deficiency, iron deficiency, bone marrow problems etc.
