SICKLE CELL ANAEMIA
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:
- Excessive temperatures
- Excessive physical activity
