- Avoid use of medicine without medical advice. Avoid high dose of Paracetamol/Tylenol. Certain herbal medical products also have the potential for liver damage.
Jaundice is a condition in which your skin and eyes turn yellow due to high levels of bilirubin in the blood. Bilirubin is a yellow pigment that is normally produced in our body when old red blood cells die. These pigments are then metabolised by the liver and excreted into the intestine via biliary ducts. Small amount of bilirubin is normally present in our blood. Bilirubin levels are elevated when there is excess levels of red blood cell breakdown, or inability of liver to process them or obstruction of the biliary duct to excrete bilirubin into the intestine.
Jaundice is sign of an underlying disease which can be a short-lived and self limiting or chronic and a serious condition. In newborns, jaundice is common and most of the time it is not harmful. However, if bilirubin levels become exceedingly high it can cause damages to the brain. Jaundice during pregnancy can have serious consequences for the mother and the fetus.
Causes of jaundice can be roughly broken into three categories based on how bilirubin increases in the blood:
Excessive red cell destruction:
Red blood cells are destroyed in large numbers that increases the blood levels of bilirubin. It is also called Pre-hepatic jaundice as there is excess bilirubin before it is transported to the liver. Some causes include:
Inability of liver to process bilirubin:
This condition is also called hepatocellular or intrahepatic jaundice. Disorders of liver cause disruption in normal handling of bilirubin leading to jaundice. Some causes of hepatocellular jaundice include:
Failure of bilirubin excretion from liver:
This condition is due to the blockage in the bile duct system. This is also called post-hepatic or obstructive jaundice. Some of the causes are:
Depending upon the cause, jaundice can show different types of symptoms:
Seek medical care when if you have any of these symptoms.
History and physical exam along with laboratory tests are used to diagnose jaundice and find out its cause. Some of the tests include:
Jaundice itself is not a disease. It is a sign of underlying disease. Several treatment strategies are used depending upon the cause.
There are several preventive measures you can take to prevent conditions that can lead to jaundice:
