Why red blood cells can cause jaundice
Red Blood Cells themselves do not cause jaundice. Jaundice is typically caused by an excess of bilirubin, a yellow pigment produced during the normal breakdown of red blood cells. When red blood cells break down, they release bilirubin, and if the liver cannot process and excrete it effectively, it can lead to the yellowing of the skin and eyes, characteristic of jaundice. So, it’s not the red blood cells but the byproduct of their breakdown, bilirubin, that is associated with jaundice.
