Health condition
Sickle cell disease in adults
Sickle cell disease in adulthood is a multisystem condition - painful crises are the visible part, but kidneys, lungs, eyes, bones and brain all need planned surveillance, and treatment options have expanded markedly.

Key facts
The essentials at a glance.
Which gene and test confirm it, who should be tested in the family, and which specialist to see.
-
Caused by the HbS variant in the HBB gene inherited from both parents (or with another variant, as in HbSC disease)
-
Adult surveillance: annual kidney, eye and pulmonary checks, blood pressure, and screening for iron overload if transfused
-
Disease-modifying options: hydroxycarbamide remains first-line; crizanlizumab, voxelotor, exchange transfusion programmes and now gene therapy extend the menu
-
Every adult should have a named specialist centre, an individual care plan and rapid-access arrangements for crises
Understanding the condition
What it is and what happens next.
What causes it, how it is confirmed, and the testing and specialist routes available in the UK.
What it is and how it presents
Adults with sickle cell disease manage a condition that touches nearly every organ: recurrent vaso-occlusive pain, chronic haemolytic anaemia, a damaged spleen that raises infection risk, and slow attritional injury to kidneys, retina, hip joints and lungs. Acute chest syndrome and stroke remain the feared emergencies. Yet outcomes track the quality of routine care closely - hydroxycarbamide alone substantially reduces crises and mortality, and remains underused.
Testing, surveillance and specialist care
UK care is organised through specialist haemoglobinopathy teams that coordinate annual multi-organ surveillance, transfusion or exchange programmes, and assessment for newer agents and curative options including stem-cell transplant and licensed gene therapies; genetic counselling and partner testing inform family planning. NHS clinical genetics services carry some of the longest waits in the health service, often many months for a first appointment, whereas private genetic testing and a specialist review can typically be arranged within around two weeks.
Seeing a specialist
Who to see, and how quickly you can be seen.
The specialist for this condition is usually a haematologist at a specialist haemoglobinopathy centre. Your GP can refer you on the NHS, or you can arrange a private consultation directly.
A quiet reminder
This guide is for information, not medical advice.
Your GP knows your history and can tell you which parts apply to you. If in doubt, see them - and seek urgent care for any emergency symptoms.
Frequently asked
Common questions about Sickle cell disease in adults.
Quick, plain-English answers to what people ask us most.
-
How does sickle cell disease affect adults?
Sickle cell disease in adulthood is a multisystem condition - painful crises are the visible part, but kidneys, lungs, eyes, bones and brain all need ongoing monitoring for complications that can develop over years.
-
What complications affect adults with sickle cell disease?
Complications can include kidney damage, lung problems such as pulmonary hypertension, eye disease from retinal changes, bone damage (avascular necrosis), and increased stroke risk, alongside recurrent painful crises.
-
How is sickle cell disease managed in adults?
Management includes regular specialist monitoring for organ complications, medications such as hydroxyurea to reduce crisis frequency, prompt treatment of infections and crises, and for some patients, blood transfusion programmes or newer targeted therapies.
-
Is sickle cell disease curable in adults?
Bone marrow (stem cell) transplant can be curative for some patients, though it carries significant risks and is not suitable for everyone; most adults are managed with ongoing supportive and preventive treatment rather than transplant.
-
What is the outlook for adults with sickle cell disease?
Life expectancy and quality of life have improved substantially with modern comprehensive care, though ongoing monitoring for organ complications and management of crises remain lifelong needs.
-
When should adults with sickle cell disease see a specialist?
Ongoing care at a specialist haemoglobinopathy centre is recommended for comprehensive monitoring. A private consultant haematologist at such a centre can typically be seen within about two weeks.
