Anemia in Pregnancy
The afternoon wall, the fog you blame on the pillow: much of pregnancy exhaustion isn't "just pregnancy," it's an iron deficit your bloodwork can miss. About one in eight US pregnancies hits iron-deficiency anemia, and more than half show it before hemoglobin drops Lewkowitz & Tuuli 2024. The routine prenatal draw checks hemoglobin but skips ferritin, the number that catches it early. One extra lab finds it; a cheap bottle of pills buys back your energy and a safer delivery.

Pregnancy dilutes your blood on purpose, so anemia cutoffs are trimester-adjusted, near 11 g/dL 1. Building a baby costs about a gram of iron, and third-trimester demand triples to six or seven milligrams absorbed a day while a normal diet supplies one or two 2. When the math runs short, red cells fall last, so fatigue and fog arrive before any lab calls you anemic.

The stakes scale with severity. Severe anemia roughly doubles the risk of dying in pregnancy or postpartum, because an anemic woman can't absorb the half-litre of blood a normal delivery loses 3. Milder anemia raises the odds of preterm birth about 1.5x 4, and even with normal hemoglobin, iron deficiency roughly doubles the odds of a transfusion after a cesarean 5.

At your first prenatal visit, ask for ferritin, not just hemoglobin. The deficiency shows up there first.

The arc, once you fix it.

  • Two to four weeks: the afternoon wall retreats; stairs stop being a project 2.
  • Delivery: a wider buffer under labor's blood loss, and less chance of a transfusion 9.
  • Postpartum: faster recovery and a narrower window for the depression a lingering deficit widens 10.
  • Baby: treated anemia tracks with babies born closer to their due date 11.

Screen earlier if any of these apply: a pregnancy in the last two years, a vegetarian or vegan diet, heavy periods, twins, IBD or celiac, bariatric surgery, acid-blocker use, or teenage pregnancy. Non-Hispanic Black women run higher rates with a documented undertreatment gap 12.

The fine print — when to skip it, and what people get wrong

"Eat more spinach" prevents but can't fix an established deficit; plant iron absorbs a fifth as well as meat's 2. "Your hemoglobin is fine" misses the low iron stores half of US pregnancies carry by the third trimester 13.

Skip treatment-dose iron with hereditary hemochromatosis or other iron overload; if it runs in the family, ask for transferrin saturation 2. Thalassemia and sickle cell trait mimic iron deficiency on a basic CBC.
