Definition

Hemolysis is the destruction of red blood cells, leading to the release of hemoglobin into the bloodstream. It can be caused by various factors including infections, autoimmune disorders, or certain nutritional deficiencies.

3. Inadequate nutrition may exacerbate hemolysis in individuals with conditions like glucose-6-phosphate dehydrogenase (G6PD) deficiency.
4. Excessive intake of certain substances, such as alcohol or some medications, can trigger hemolysis.
5. Monitoring hemoglobin levels is crucial for managing patients at risk of hemolysis due to poor nutritional status.
