Sickle cell anaemia is a hereditary blood disorder, caused by abnormal haemoglobin found in red blood cells.

Causes of sickle cell anaemia

  • In people with sickle cell anaemia the shape and texture of the blood cells can change.
  • The cells become hard and sticky and are shaped like sickles, or crescents.
  • The cells die prematurely leading to a shortage of red blood cells.
  • This causes the symptoms of anaemia such as tiredness and breathlessness.

Symptoms of sickle cell anaemia

  • If you have sickle-cell anaemia, your blood cells can get stuck when moving through small blood vessels, stopping the supply of oxygen to parts of your body.
  • This is known as a 'sickle crisis'.
  • This can cause pain, tissue damage, and can lead to other serious complications, such as a stroke, or blindness.

Treatments for sickle cell anaemia

  • The only cure for sickle cell anaemia is a stem cell transplant.
  • However a bone marrow transplant has many potentially serious side effects and is not recommended for all cases.
  • The symptoms of sickle cell anaemia can be treated and people with the condition can learn how to help prevent a sickle crisis from happening.

Common triggers of a sickle cell crisis include:

  • Infections
  • Dehydration
  • Stress
  • Excessive temperatures
  • Excessive physical activity
