Iron deficiency anemia occurs when the level of red blood cells in the body is lower than normal, meaning the body doesn't have enough iron. The body needs iron to make a protein known as hemoglobin, which is responsible for carrying oxygen to the body's tissues. This process is essential for the tissues and muscles to function effectively. (1)
Several factors contribute to iron deficiency anemia including:
- Inadequate Iron Intake - eating too little iron over an extended amount of time can cause a shortage in the body. Foods such as meat, eggs and green leafy vegetables are high in iron.
- Pregnancy or Blood Loss Due to Menstruation - In adult women, the most common causes of iron deficiency anemia are heavy menstrual bleeding and blood loss during childbirth.
- Internal Bleeding - Certain medical conditions can cause internal bleeding which can lead to iron deficiency anemia.
- Inability to Absorb Iron - Certain disorders or even surgeries that affect the intestines can interfere with how the body absorbs iron.
