The short explanation
Your mother's doctor is being careful for a good reason. In a woman after menopause, there is no monthly blood loss to explain new anaemia, so doctors want to find the actual cause. Some causes are simple, such as poor diet, low B12 or kidney function changes, but others need to be found early, such as slow bleeding from the stomach or bowel. That is why the tests may include iron studies, B12 and folate, kidney function, and sometimes a stool test, endoscopy or colonoscopy. Finding the reason matters more than just raising the number with tablets.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Regular painkillers for joint pain, blood thinners and aspirin can cause slow bleeding from the stomach.
- Weight loss, a change in bowel habits, black stools, or loss of appetite make further tests more important.
- Long-term illnesses such as kidney disease, thyroid problems and diabetes can also cause anaemia in older adults.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you why your mother is anaemic. Only the tests her doctor has suggested can find the cause.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- What are the likely causes in her case?
- Which tests are most important first?
- Could her medicines be contributing?
- Will she need a camera test of the stomach or bowel?
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 if she faints, has chest pain, severe breathlessness, or vomits blood.
Get help the same day
- Get care the same day if she passes black or bloody stools, or becomes confused or very weak.
Book an appointment soon
- Complete the suggested tests within days rather than delaying.
