Sickle Cell Anaemia
Sickle cell anaemia is an inherited form of sickle cell disease in which abnormal haemoglobin makes red cells rigid under certain conditions. Cells can break down and obstruct small blood vessels, causing anaemia, pain and organ injury.
Key takeaways
- A pain crisis may be severe, but fever, chest symptoms, neurological change or an enlarged spleen can signal a separate emergency.
- Care includes vaccination, infection prevention, pain plans, organ monitoring and disease-modifying options under specialist follow-up.
- Hydroxycarbamide can reduce complications for selected patients but needs blood-count, pregnancy and toxicity monitoring.
Catalogue matches are not a crisis plan and do not indicate that a blood or pain medicine is suitable.
Why can complications develop suddenly?
Sickling can reduce blood flow to bone, lungs, brain, spleen or other tissue. Infection risk is also increased when spleen function is impaired. Personal action plans help distinguish a familiar pain episode from warning symptoms.
What does long-term care target?
Hydration, avoiding known extremes, immunisation and prompt fever assessment support care. Hydroxycarbamide raises fetal haemoglobin and may reduce vaso-occlusive events, but benefit and adverse effects require specialist review. Sickle cell disease is a haemoglobin disorder, not a blood cancer, even if related medicines appear under oncology support.
When to seek urgent care
Seek emergency care for fever, chest pain, breathlessness, new weakness or speech change, severe headache, unusual drowsiness, sudden abdominal enlargement or a painful erection lasting several hours.
