Sickle cell disease

Also called Sickle cell anaemia or SCD

Sickle cell disease is the name for a group of inherited conditions that affect the red blood cells. People with it make red blood cells shaped like a sickle or crescent, which can block blood vessels and do not live as long as normal cells. It is most common in people with African, Caribbean, Middle Eastern, Eastern Mediterranean or Asian family origins.

What it is

It is a lifelong condition. People with it can have episodes of severe pain (sickle cell crises), anaemia and a higher risk of infections and stroke.

Treatment includes daily antibiotics and vaccines to prevent infection, painkillers, medicines such as hydroxycarbamide, and sometimes blood transfusions. A stem cell transplant can cure it in some people.

Common signs

  • Episodes of severe pain (crises)
  • Tiredness and shortness of breath from anaemia
  • Frequent infections
  • Yellow skin or eyes
  • Delayed growth in children

How it is usually diagnosed

  • Newborn blood spot screening
  • Blood tests
  • Screening in pregnancy for carriers

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Blood test results
  • Haematology letters
  • Transfusion records
  • Vaccination records
  • Care plans for crises

Questions to ask your doctor

  • What should I do during a pain crisis?
  • Which vaccines and antibiotics do I need?
  • Would hydroxycarbamide or a transplant be an option?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Chest pain, breathlessness, signs of a stroke, a high temperature, or pain not controlled at home: call 112
