anemia primary causes
Causes of iron deficiency anemia include: 1  Blood loss. 2  A lack of iron in your diet. 3  An inability to absorb iron.  Pregnancy.
As a result, the bone marrow makes fewer red blood cells, causing anemia. When blood has fewer red blood cells, it deprives the body of the oxygen it needs. Other common causes of anemia in people with kidney disease include blood loss from hemodialysis and low levels of the following nutrients found in food: iron.
Anemia is a condition in which the body has fewer red blood cells than normal. Red blood cells carry oxygen to tissues and organs throughout the body and enable them to use energy from food. Anemia commonly occurs in people with chronic kidney disease (CKD)âthe permanent, partial loss of kidney function.
