- Anaemia means there are not enough healthy red blood cells or haemoglobin to carry oxygen normally.
- Iron deficiency may come from heavy periods, gastrointestinal blood loss, pregnancy, poor intake or poor absorption.
- Taking iron without identifying the cause can miss ongoing bleeding or another medical problem.
Why this deserves attention
Iron deficiency can cause tiredness, reduced exercise tolerance and paleness, but the important question is why iron became low. Blood loss or diet may need investigation.
The same symptom can have several causes. Useful clues include how quickly it changed, how severe it is, what comes with it, personal risk factors and whether it is clearly different from your normal baseline.
What to observe
Notice fatigue, paleness, breathlessness with activity, fast heartbeat, dizziness, heavy periods, black/bloody stools and dietary pattern.
Write down when symptoms happen, how long they last, triggers, changes in normal function and medicines or supplements already taken. A short record often makes a consultation more useful.
Sensible next steps
Ask for a medical assessment and blood count/ferritin when symptoms or risk factors fit. Do not assume fatigue automatically means iron deficiency.
Medical assessment and where TCM fits
Iron treatment depends on the cause and severity. Ongoing blood loss may need gynaecological or gastrointestinal investigation.
TCM dietary support can complement a medically confirmed plan, but herbs should not replace investigation of significant blood loss or prescribed iron therapy.
TCM and conventional care can sometimes complement each other, but acute red flags, conditions needing imaging or blood tests, and diseases with established evidence-based treatment require diagnosis and safety to come first.
When not to wait
Chest pain, fainting, severe breathlessness, rapidly worsening weakness, vomiting blood, black stools or heavy uncontrolled bleeding requires urgent assessment.
