Anemia during pregnancy

Definition

A condition in which maternal blood hemoglobin levels fall below 11 g/dL during pregnancy, most commonly due to iron deficiency. Anemia can lead to fatigue, shortness of breath, and increased complications during labor.

How it works

Pregnancy-related anemia most commonly results from iron deficiency, as iron requirements increase 50% to support expanded blood volume and fetal needs. Without adequate iron intake and absorption, hemoglobin production cannot keep pace with blood volume expansion. Anemia reduces oxygen-carrying capacity, leading to maternal fatigue, weakness, and reduced exercise tolerance. Severe anemia increases risks of preterm birth, low birth weight, and postpartum complications including increased bleeding and infection. Early detection through routine blood testing and prompt treatment with iron supplementation prevents complications. Folate and vitamin B12 deficiencies can also cause pregnancy anemia and should be assessed.

Role

Indicates insufficient hemoglobin production, compromising oxygen delivery to mother and fetus.

Examples

• Iron supplements
• Red meat
• Poultry
• Fish
• Legumes
• Fortified cereals
• Vitamin C-rich foods to enhance absorption

Recommendations

Follow screening for anemia at routine prenatal visits and take iron supplements as prescribed if anemia is detected. Enhance iron absorption by taking supplements with orange juice or vitamin C supplements. If experiencing severe symptoms, report them immediately to your healthcare provider.

Key takeaway

Early detection and treatment of pregnancy anemia prevents complications and ensures optimal oxygen delivery to the fetus.
