Iron Deficiency Anemia: Symptoms, Causes & Diagnosis

Iron deficiency anemia is a condition that develops when your body lacks enough iron. Iron is an essential mineral that your body needs to make hemoglobin, a protein in red blood cells that carries oxygen throughout your body. Without enough iron, your body can't produce enough hemoglobin, which leads to anemia.

Iron deficiency anemia is the most common type of anemia worldwide. It can affect people of all ages, but it is most common in:

- Pregnant women

- Children and adolescents

- Women of childbearing age

- People with chronic diseases, such as cancer, kidney disease, or heart disease

Symptoms of iron deficiency anemia can include:

- Fatigue and weakness

- Shortness of breath

- Pale skin

- Brittle nails

- Headache

- Dizziness

- Cold hands and feet

- Restless legs syndrome

- Difficulty concentrating

- Irritability

In severe cases, iron deficiency anemia can lead to:

- Heart problems

- Stroke

- Pregnancy complications

- Developmental delays in children

If you think you may have iron deficiency anemia, talk to your doctor. They can do a blood test to check your iron levels and recommend treatment if necessary. Treatment for iron deficiency anemia typically involves taking iron supplements and eating a diet rich in iron-rich foods, such as red meat, poultry, fish, beans, lentils, spinach, and dried fruit.
