Bilirubin is a yellow compound that occurs in the body when red blood cells break down. It is produced in the liver and is a key component of bile, which helps in the digestion of fats. Bilirubin levels can be measured through blood tests, and they are important for assessing liver function and overall health.
High levels of bilirubin can lead to a condition called jaundice, which causes yellowing of the skin and eyes. This can occur due to various reasons, including liver disease, bile duct obstruction, or hemolysis, where red blood cells are destroyed faster than they can be produced.
