Common Symptoms of Iron Deficiency After Chemotherapy
Helping you recognise them early and address them gently
Iron deficiency after chemotherapy is experienced by more than 50 % of patients.
Chemotherapy drugs not only suppress bone-marrow blood production but also cause gut absorption issues, chronic blood loss, or inflammatory consumption, rapidly depleting iron stores.
Iron is not just the “raw material for haemoglobin” — it is essential for oxygen transport, energy production, and immune function.
When iron is low, your body signals the need for replenishment through these symptoms.
The five most common symptoms of iron deficiency
- Extreme fatigue — feeling as if you haven’t slept even after rest, with sudden “power outages” in the afternoon
- Dizziness, palpitations, shortness of breath — especially when climbing stairs or walking quickly
- Cold hands and feet, brittle or spoon-shaped nails
- Pale skin, lips, and inner eyelids
- Poor concentration, brain fog, and reduced memory
Other signs that are easily overlooked
- Hair loss more noticeable than during treatment
- Wounds or mucosal ulcers healing unusually slowly
- Pica (craving non-food items like ice or dirt)
- Restless legs syndrome (RLS) — uncomfortable legs at night affecting sleep
- Recurrent infections or prolonged colds
Why iron deficiency is particularly common after chemotherapy
- Chemotherapy suppresses bone marrow, reducing red-blood-cell production and iron utilisation
- Damage to gut mucosa impairs iron absorption
- Nausea and poor appetite during treatment limit iron intake
- Chronic inflammation “locks” iron in storage, making it unavailable
- Surgical or tumour-related bleeding causes direct iron loss
Gentle and effective ways to restore iron levels
- Blood tests first to confirm ferritin, transferrin saturation, and complete blood count
- Oral iron if tolerated, starting low to minimise constipation
- Intravenous iron for poor tolerance or absorption — faster results with fewer side effects
- Pair with vitamin C-rich foods (oranges, kiwi) to enhance absorption
- Avoid tea, coffee, or calcium supplements at the same time, as they hinder iron uptake
Summary
Iron-deficiency symptoms after chemotherapy are often mistaken for “just fatigue” or “normal recovery”.
