Iron deficiency anemia occurs when your body doesn't have enough iron to produce hemoglobin—the part of red blood cells that gives blood its red color and enables the red blood cells to carry oxygen to your body. It can be caused by a number of conditions.

Common causes of IDA

  • Iron in your body is either depleted or not fully replenished due to causes such as blood loss, lack of dietary iron, inability to absorb iron, or pregnancy
  • Low iron levels occur (iron deficiency), and you don’t have enough iron to keep you in good health
  • If iron deficiency progresses, it may cause iron deficiency anemia, as iron helps produce hemoglobin, which is a protein that helps carry oxygen from the lungs to cells in the body
  • Many diseases and conditions may cause or lead to IDA
Intestines icon Gastrointestinal Conditions Even if you have enough iron in your diet, your body may not be able to absorb it. This can happen if you have intestinal surgery (such as gastric bypass) or a disease of the intestine (such as Crohn's disease, ulcerative colitis, or celiac disease).
Kidney icon Chronic Kidney Disease IDA is a common among people with chronic kidney disease (CKD). This may be because of impaired intestinal absorption of dietary iron, chronic blood loss, chronic inflammation, and/or increased iron requirements during the administration of certain therapies.
Female symbol icon Women’s Health Conditions Iron is found in red blood cells in our blood and so when you lose blood, you lose some iron, too. That’s why long or abnormal periods, bleeding fibroids in the uterus, or blood loss during childbirth may cause low iron levels.
Heartbeat icon Heart Failure People with chronic heart failure can suffer from gastrointestinal bleeding and the inability to absorb enough iron, which can lead to IDA.
Cancer Ribbon icon Cancer Cancer-related anemia can develop due to many reasons, including chemotherapy, chronic blood loss, lack of a certain hormone in people with kidney disease, and marrow involvement with tumor, among others.
Blood icon Blood loss from injury or surgery Major surgery or physical traumas like cuts, gashes, or wounds can cause the body to lose blood.
