The short explanation
Your doctor's concern is reasonable. During delivery some blood loss is expected, and a woman who starts labour with low haemoglobin has less reserve to cope with it. Severe anaemia late in pregnancy can raise the chances of needing a transfusion, feeling very weak after birth, and recovery being slower. It can also affect the baby's growth. In the last weeks of pregnancy, tablets may be too slow to raise haemoglobin in time. IV iron can raise it faster and is commonly used in later pregnancy. A blood transfusion is usually kept for very low levels, symptoms such as breathlessness, or when delivery is very close. Your doctor will choose based on your level and how many weeks remain.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Ask your doctor how low your level is and what target they would like before delivery.
- Delivering in a hospital equipped to handle bleeding and transfusion is especially important with anaemia.
- Government hospitals provide IV iron and transfusions for pregnant women, often free under maternal health schemes.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you how risky your situation is or which treatment is right. Your obstetrician knows your level, symptoms and timing.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- How low is my Hb and what level are you aiming for?
- Why IV iron rather than tablets now?
- When would a transfusion be needed?
- Should I deliver at a hospital with a blood bank?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Emergency — call 112 now
- Call 112 or go to the labour ward immediately if you have bleeding, fainting, chest pain or severe breathlessness.
Get help the same day
- Get care the same day if you feel very dizzy, your heart races at rest, or the baby is moving less.
Raise it at a routine appointment
- Follow the treatment plan and attend all appointments in the remaining weeks.
