Normal red blood cells have a round, flexible shape that allows them to move easily through blood vessels. In sickle cell disease, red blood cells take on an abnormal sickle shape, which causes a range of serious health problems. Sickle cell disease is the name for a group of inherited health conditions that affect the red blood cells.
Sickle cell disease is particularly common in people with an African or Caribbean family background. People with the condition produce these unusually shaped red blood cells, which cause problems for two key reasons: they do not live as long as healthy blood cells, and they can block blood vessels.
Sickle cell disease is a serious and lifelong health condition, but treatment can help manage many of its symptoms. This article covers the causes, symptoms, and treatment options to help you understand more about the condition.
Causes of Sickle Cell Disease
Sickle cell disease is caused by a gene that affects how red blood cells develop. If both parents carry this gene, there is a one in four chance that each child they have will be born with sickle cell disease. However, the parents often will not have the disease themselves, as they may only be carriers of the sickle cell trait.

Because of this, you can request a blood test to check whether you carry the sickle cell trait. This can be arranged through your doctor or the nearest sickle cell center.
Symptoms of Sickle Cell Disease
People born with sickle cell disease tend to experience problems from early childhood, although some children have few symptoms and can lead normal lives most of the time. The main symptoms include:
- Painful episodes known as sickle cell crises, which can be very severe and last for days or weeks.
- Increased risk of serious infections.
- Anemia, where red blood cells cannot carry enough oxygen around the body, leading to tiredness and shortness of breath.
Some people may also experience additional complications such as delayed growth, strokes, or lung problems.
Diagnosing Sickle Cell Disease
In the UK, people are often aware they have sickle cell disease because it is detected during pregnancy or shortly after birth. Screening for sickle cell disease during pregnancy is offered to all pregnant women in England to check whether there is a risk of a child being born with the condition. All babies are also offered screening as part of the newborn blood spot test, also known as the heel prick test.

If you do not live in England, check with your own health provider to find out whether you have been screened, particularly if you are at risk or have any symptoms. Blood tests can be carried out at any age to check for the disease or to determine whether you are a carrier of the gene.
Treatment Options for Sickle Cell Disease
It is important to understand that people with sickle cell disease require treatment throughout their lives. This is usually delivered by different health professionals working together at a specialist sickle cell center. If you have sickle cell disease, following the guidance provided by your healthcare team to look after your own health is essential.
A range of treatments are available, from straightforward steps you can take at home to more complex medical interventions.
At-Home and Preventative Measures
- Drinking plenty of fluids and staying warm to help prevent painful episodes.
- Taking painkillers such as paracetamol or ibuprofen to manage pain. Stronger painkillers administered in hospital may sometimes be necessary.
- Taking daily antibiotics and keeping up to date with vaccinations to reduce the risk of infection.
Medical Treatments
- Specialist medicines to help reduce symptoms.
- Regular blood transfusions if symptoms continue, worsen, or if there are signs of damage caused by the disease.
- Emergency blood transfusions in cases where severe anemia develops suddenly.
The Only Known Cure
The only cure for sickle cell disease is a stem cell or bone marrow transplant. However, these procedures are not carried out frequently due to the significant risks involved.
Outlook for People with Sickle Cell Disease
The outlook for sickle cell disease varies between individuals, ranging from mild to serious. Most people with the condition go on to live happy and fulfilling lives. For this reason, it is important to be aware of the things that can make sickle cell disease worse, to avoid potential triggers, and to be informed about all available treatment options.

Mild sickle cell disease may have little to no impact on a person’s daily life. However, the illness can be serious enough to significantly affect quality of life and can potentially lead to complications such as strokes, serious infections, and lung problems.
Overall, life expectancy for someone with sickle cell disease tends to be shorter than average, though this varies depending on the specific type of sickle cell disease, how it is treated, and what complications a person experiences. Research into sickle cell disease is ongoing and is continuously improving outcomes for those living with the condition.
Frequently Asked Questions (FAQ)
Q: What is sickle cell disease?
A: Sickle cell disease is the name for a group of inherited health conditions that affect red blood cells. People with the condition produce abnormally shaped, sickle-shaped red blood cells that do not function properly and can block blood vessels.
Q: Who is most commonly affected by sickle cell disease?
A: Sickle cell disease is particularly common in people with an African or Caribbean family background, though it can affect people from other backgrounds as well.
Q: How is sickle cell disease inherited?
A: It is caused by a gene passed down from both parents. If both parents carry the sickle cell gene, there is a one in four chance of each child being born with the condition. Parents who are only carriers often do not have the disease themselves.
Q: Can I find out if I am a carrier of the sickle cell gene?
A: Yes. You can request a blood test through your doctor or nearest sickle cell center to find out whether you carry the sickle cell trait.
Q: What are the main symptoms of sickle cell disease?
A: The main symptoms include painful episodes known as sickle cell crises, an increased risk of serious infections, and anemia, which can cause tiredness and shortness of breath. Some people also experience delayed growth, strokes, or lung problems.
Q: Is sickle cell disease curable?
A: The only known cure is a stem cell or bone marrow transplant. However, due to the risks involved, this procedure is not commonly performed. Most treatment focuses on managing symptoms and preventing complications.
Q: What can I do at home to manage sickle cell disease?
A: Staying well hydrated, keeping warm, taking appropriate pain relief, and keeping up with vaccinations and daily antibiotics as prescribed are all important steps. Always follow the guidance of your healthcare team.
Q: What is the life expectancy for someone with sickle cell disease?
A: Life expectancy tends to be shorter than average for people with sickle cell disease, but this varies significantly depending on the type of the condition, how it is managed, and what complications arise. Many people live long and fulfilling lives with appropriate care.
Q: Where can I find more information and support?
A: The Sickle Cell Society is a UK charity that provides a wide range of information, research updates, and details of support groups for people living with sickle cell disease.
Conclusion
Sickle cell disease is a serious, lifelong condition, but with the right knowledge, support, and treatment, many people live full and active lives. Understanding the causes, recognising the symptoms early, and staying engaged with your healthcare team are all key to managing the condition effectively. Research continues to advance, bringing hope for improved treatments and outcomes in the future.
