Others need treatment to lower bilirubin levels. Call the doctor if your baby: starts to look or act sick is not feeding well is sleepier than usual has jaundice that gets worse What Causes Jaundice in Newborns? A baby is more likely to get jaundice when he or she: is born premature.
Premature babies are even less ready to remove bilirubin. They also can have problems at lower bilirubin levels than babies born later. Doctors treat them sooner. This often happens in the first few days of life, because a mother's milk isn't in yet or the baby is having trouble breastfeeding. If a baby has this type of jaundice called breastfeeding jaundice , it's best to feed more often. A breastfeeding lactation consultant can help. Breast milk prevents the liver from quickly removing bilirubin.
This is called breast milk jaundice and happens after the first week of life. Bilirubin levels slowly improve over 3—12 weeks. If mother and baby have different blood types, the mother's body makes antibodies that attack the baby's red blood cells. This happens when: the mother's blood type is O and the baby's blood type is A or B ABO incompatibility or the mother's Rh factor a protein found on red blood cells is negative and the baby is Rh positive.
Red blood cells break down more easily in health problems like hereditary spherocytosis and G6PD deficiency. This causes the production of more bilirubin. Also, the livers of infants are less developed and, therefore, less effective at filtering bilirubin from the body. Symptoms will usually resolve without treatment within 2 weeks. However, infants with extremely high bilirubin levels will require treatment with either a blood transfusion or phototherapy.
In these cases, treatment is vital as jaundice in newborns can lead to kernicterus, a very rare type of permanent brain damage. The level of bilirubin is defined in a blood test called a bilirubin test. This measures unconjugated, or indirect, bilirubin levels.
These are responsible for the onset of jaundice. Adults and older children should have a level of between 0. If they show higher levels than this, they are usually referred for further investigation.
These ranges may differ between laboratories. Doctors will most likely use the history of the patient and a physical exam to diagnose jaundice and confirm bilirubin levels. They will pay close attention to the abdomen, feel for tumors, and check the firmness of the liver.
A firm liver indicates cirrhosis , or scarring of the liver. A rock-hard liver suggests cancer. Several tests can confirm jaundice. The first is a liver function test to find out whether or not the liver is functioning properly. If a doctor cannot find the cause, a doctor may request blood tests to check bilirubin levels and the composition of the blood. These include:. The doctor will examine the structure of the liver if they suspect an obstruction.
They may also carry out an endoscopic retrograde cholangiopancreatography ERCP. This is a procedure combining endoscopy and X-ray imaging. The gallbladder squeezes contracts when we eat.
This empties the stored bile back into the common bile duct and out into the duodenum. The bilirubin in the bile gives the stools faeces their typical brown colour. So, getting rid of bilirubin is a normal process. It is when abnormal amounts of bilirubin build up in the blood that you become jaundiced. And this can happen for many different reasons.
Various conditions cause an increased rate of breakdown of red blood cells. As a result, there is more bilirubin made than usual which then circulates in the blood.
The liver cells are unable to keep pace and process the extra bilirubin. Therefore, a backlog of bilirubin builds up in the blood awaiting the liver cells to process it. This increased amount of bilirubin then spills into the tissues of the body to cause jaundice.
Conditions that cause an increased rate of breakdown of red blood cells include:. If the tiny bile ducts within the liver become damaged or narrowed then the flow of bile is restricted. A backlog of bile which contains bilirubin then spills into the bloodstream. Various conditions can affect or damage the bile ducts in this way. For example, primary biliary cirrhosis , primary sclerosing cholangitis and as a side-effect of some medicines.
The bile from all the tiny bile ducts in the liver drains into the common bile duct. If the common bile duct becomes narrowed or blocked obstructed then bile which contains bilirubin can seep out into the bloodstream and cause jaundice.
This is sometimes called obstructive jaundice or posthepatic jaundice hepatic is another word for liver. Conditions that can cause this include:. The whites of the eyes are often the first tissues that you notice turning yellow when you develop jaundice. If the bilirubin level is only mildly high then this might be the only part of the body where you can detect a yellow colour.
With higher levels of bilirubin, the skin also becomes yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching. If damage to the liver is severe, jaundice may be accompanied by serious problems, such as deterioration of brain function and a tendency to bleed or bruise. Acute viral hepatitis is a common cause of jaundice, particularly in young and otherwise healthy people.
