III: Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism

D55-D59: Haemolytic anaemias

Haemolytic anaemias are a group of blood disorders characterized by the premature destruction of red blood cells, leading to a shortage of these cells in the body. They occur as a result of various factors such as inherited genetic disorders, immune dysfunction, or external factors like infections, toxins, or certain medications. Symptoms commonly observed include fatigue, paleness, rapid heart rate, shortness of breath, and yellowing of the skin and eyes. The disease progression varies based on the underlying cause and severity but often involves episodes of worsening symptoms, known as crises, which may be triggered by infections or stress. Throughout the course of these conditions, the blood, immune, and cardiovascular systems of the body may be affected. Despite the symptoms and complications, many people with haemolytic anaemias lead full, healthy lives with proper management and care.
