Iron deficiency anemia occurs when the body does not have enough
iron. It can cause weakness, pale skin, and general tiredness.
The body needs iron to produce new red blood cells. Low iron levels
can be caused by:
- Bleeding from conditions such as ulcers, heavy
menstrual periods, or cancer.
- Poor absorption of iron by the
body.
- Lack of iron in the diet or not enough iron in the diet
during times of growth, such as pregnancy, early childhood, and the teen
years.
Iron deficiency anemia is usually diagnosed using blood tests, but
the cause is usually found when the doctor is taking a medical history or
performing a colonoscopy. Treatment often includes making diet changes, taking
iron supplements, and treating other conditions or problems that may be causing
iron deficiency. In rare cases, blood transfusions may be needed.
