Chemotherapy-Induced Anemia: Symptoms, Causes, Treatment
فقر الدم أثناء العلاج الكيميائي
Anemia during chemotherapy means reduced hemoglobin and oxygen-carrying capacity. Fatigue is common but does not establish the diagnosis; care depends on the cause and symptoms.
What is Chemotherapy-Induced Anemia?
Anemia is not always iron deficiency. Marrow suppression, bleeding, nutritional deficiencies and kidney disease may overlap, and the intent of cancer treatment affects management.

Symptoms
Symptoms include unusual fatigue, pallor, dizziness, palpitations and breathlessness on exertion. Mild anemia may be silent; heart or lung disease can worsen its impact.
Causes
Chemotherapy or cancer involving the marrow can reduce red-cell production. Inflammation and iron, vitamin B12 or folate deficiency are additional possible contributors.
Risk factors
Marrow-suppressing treatment, blood loss, poor nutrition and kidney impairment increase risk. Anemia present before cancer treatment also needs assessment.
Diagnosis
A complete blood count measures hemoglobin. Iron studies, vitamin levels, kidney tests or bleeding investigations may follow according to the history and findings.
Treatment
Treatment may correct a proven deficiency, provide red-cell transfusion or adjust chemotherapy. Erythropoiesis-stimulating agents suit selected cases, generally with noncurative treatment, after discussing clotting risks.
Complications
Anemia may restrict function, strain the heart and delay treatment. No single hemoglobin value determines transfusion for everyone without considering symptoms and risks.
Prevention
Balance activity and rest, maintain appropriate nutrition and attend blood tests. Do not start iron or blood-stimulating injections solely for fatigue without identifying the cause.
When to see a doctor
Breathlessness at rest, chest pain, fainting or persistent bleeding requires emergency care. Tell the oncology team about worsening dizziness or fatigue that limits daily activities.
