From the opening chapter

Autoimmune haemolytic anaemia (AIHA) occurs when your immune system produces antibodies that mistakenly identify your own red blood cells as foreign invaders and destroy them. This process, called haemolysis, happens faster than your bone marrow can produce replacement cells, leading to anaemia. The condition affects approximately 1-3 per 100,000 people annually in the United Kingdom, making it a rare but significant haematological disorder that can profoundly impact your daily life. Your immune system normally protects you from infections and foreign substances by producing antibodies—specialised proteins that recognise and neutralise threats. In AIHA, these antibodies target proteins on the surface of your red blood cells, marking them for destruction by other immune cells, particularly in your spleen, liver, and bone marrow. This autoimmune response can develop suddenly or gradually, and whilst the exact triggers remain unclear in many cases, current research suggests links to infections, medications, other autoimmune conditions, or certain cancers.
