Iron-Deficiency Anaemia in Pregnancy: What Every Expecting Mother Should Know

Pregnancy roughly doubles a woman's need for iron. The body has to build extra blood for itself and supply the growing baby at the same time. When iron stores cannot keep up, anaemia follows — and in pregnancy it is both more likely and more consequential.

This is not a rare complication. In our part of West Bengal, where anaemia in women already runs above 70%, a large share of pregnancies begin with iron stores already low. The pregnancy then draws them down further.

Why it matters for the baby

Maternal anaemia is linked to higher risks of preterm birth, low birth weight, and complications during delivery. Severe anaemia raises the danger around childbirth itself, when blood loss is harder to tolerate if you started low. The baby's own iron stores at birth depend partly on the mother's, which is why maternal anaemia can carry into infant anaemia.

None of this is meant to alarm. It is meant to explain why your haemoglobin is checked more than once during pregnancy, and why the check is not a formality.

The signs are easy to miss in pregnancy

Pregnancy already brings tiredness, breathlessness, and a faster heartbeat. Those overlap exactly with anaemia symptoms, which makes anaemia easy to write off as "just pregnancy." That overlap is precisely why a number from a test matters more here than how you feel. You cannot reliably judge anaemia by symptoms during pregnancy. You have to measure it.

What helps

The mainstays are familiar: iron and folic acid supplementation as advised, a diet with more iron-rich foods where possible, and treating any underlying cause your doctor finds. The earlier this starts, the more time there is for stores to recover before delivery.

Iron-rich foods worth knowing about include green leafy vegetables, legumes and dals, jaggery, and — for those who eat them — eggs, liver, and meat. Pairing iron sources with vitamin C, like a citrus fruit, helps absorption. Tea with meals does the opposite, so it is better kept between meals.

The screening point

The single most useful thing is simple: get your haemoglobin checked early in pregnancy, and again as advised. A first-trimester reading sets a baseline. A later one catches the decline that often comes as the pregnancy progresses.

Our work is about making that check easier to get — at the antenatal visit, without an extra trip, without a separate needle each time. For a pregnant woman already balancing a dozen things, lowering the cost of finding out is the whole point.

FAQ

How often should haemoglobin be checked in pregnancy? At least at the first antenatal visit and again later in pregnancy, with more checks if anaemia is found. Follow your provider's schedule.

Can diet alone fix anaemia in pregnancy? Diet helps, but iron needs in pregnancy are usually high enough that supplementation is recommended alongside it. Discuss this with your provider.

Is mild anaemia in pregnancy dangerous? Mild anaemia is common and treatable, but it should still be monitored, because it can worsen as pregnancy continues.
