Question

When red blood cells are attacked by the immune system in autoimmunity, what condition results?

Options

• Hashimoto's disease

• Chronic anaemia

• Myasthenia gravis

• Rheumatoid arthritis

Answer 1

If red blood cells are attacked, the body destroys its own RBCs, resulting in chronic anaemia. This is a direct consequence of the autoimmune response targeting self-antigens present on red blood cells, leading to their destruction and subsequent reduction in oxygen-carrying capacity.
