The short explanation
Please treat this as an emergency and get her to hospital now. Chest pain and breathlessness on very small effort can happen when anaemia becomes severe, because the heart has to work much harder to supply oxygen. But the same symptoms can also come from a heart attack, heart failure or a lung problem, and in older women these can be harder to recognise. Doctors need to check her heart with an ECG, measure her haemoglobin and look for any bleeding. If her haemoglobin has dropped a lot, she may need a blood transfusion. The important thing is not to wait to see if it settles.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Diabetes, high blood pressure or heart disease make urgent assessment even more important.
- Black stools, vomiting blood or heavy bleeding would suggest the haemoglobin has fallen because of blood loss.
- Take her medicine list and any recent blood reports to the hospital.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether her symptoms come from anaemia, her heart or something else. She needs to be examined urgently.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Is this from anaemia, her heart, or both?
- How low is her haemoglobin now?
- Does she need a transfusion?
- What caused her haemoglobin to drop?
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 take her to the nearest emergency department now. Do not let her walk or exert herself.
Get help the same day
- If you are unsure whether it is serious, still get her seen at a hospital the same day, not at a routine clinic.
