What should you know about sickle cell disease and thalassemia?

Sickle cell disease changes the shape and flexibility of red blood cells under certain conditions. The cells may obstruct small blood vessels and cause episodes of pain, anaemia, and reduced oxygen delivery. Thalassemia affects how much of particular haemoglobin chains the body makes, which can reduce healthy red blood cell production and cause anaemia. Both conditions are inherited, but their gene patterns and clinical courses differ.

Fatigue, joint pain, and pale skin can occur with several causes of anaemia, so none of these symptoms identifies one condition. A blood test can examine haemoglobin and red blood cell features. Further testing may be needed before a clinician can name the condition or carrier state.

Take any previous blood results to your appointment and mention relatives with a haemoglobin disorder. Ask whether you need haemoglobin analysis, genetic counselling, or testing for a partner or family member. Premarital screening can be discussed when relevant to family planning. Treatment is condition-specific: iron is useful for confirmed iron deficiency, but it does not treat every inherited anaemia.

Seek urgent assessment for severe or sudden pain, fever, chest pain, breathlessness, fainting, confusion, or new weakness. These warning signs should be assessed promptly rather than attributed to a known anaemia. Arrange a routine review if fatigue is persistent, skin looks unusually pale, or a test has shown anaemia without a clear explanation.

Ask which haemoglobin condition, if any, the results support and whether you are a carrier. Ask what additional blood tests are needed, whether relatives should be tested, and how the result could affect pregnancy planning. Also ask which symptoms require same-day care.
