Repeated fatigue, weakness, dizziness, breathlessness, a fast heartbeat, or pallor may be associated with anaemia. A blood test can identify low haemoglobin, but that is the beginning of the assessment—not the complete diagnosis.
Why the cause matters
Anaemia may be related to iron, vitamin B12, or folate deficiency; blood loss; infection; inflammation; kidney disease; another chronic illness; or an inherited blood disorder.
Because the causes differ, taking iron without assessment is not the right answer for every patient. A clinician may review diet, menstrual or gastrointestinal blood loss, medicines, medical history, and relevant laboratory findings before recommending treatment.
A practical evaluation may include
- confirming the degree and type of anaemia;
- looking for an underlying source of blood loss;
- assessing nutrition and absorption;
- reviewing chronic conditions such as diabetes or kidney disease; and
- planning treatment and follow-up according to the cause.
Seek timely care if weakness is severe, breathlessness occurs at rest, there is chest pain, fainting, active bleeding, black stools, or rapid worsening.
Tests and treatment depend on the pattern
A complete blood count shows more than haemoglobin: red-cell size and other blood-cell results can guide the next question. Depending on the findings, a clinician may consider iron studies, vitamin B12 or folate, kidney function, a bleeding assessment, or tests for inherited haemoglobin disorders. Every patient does not need every test.
Iron-rich foods can help nutrition, but diet alone cannot correct every cause of anaemia. Avoid taking iron tablets, injections or a “blood tonic” simply because you feel tired. In men and women after menopause, iron deficiency may need evaluation for hidden gastrointestinal blood loss. Heavy periods, black stool, weight loss and regular painkiller use should be discussed.
Treatment may involve replacing a confirmed deficiency, treating bleeding or another illness, or specialist care. Ask when haemoglobin and iron stores should be checked again. Bring previous CBC reports and all medicines to the visit; side effects such as constipation can often be managed by adjusting the treatment plan.
