Jaundice And Newborns: Yellow Poop Explained

Jaundice is a common condition in newborns, causing a yellow discolouration of the skin and eyes. It is caused by a buildup of bilirubin in the blood when the liver is not developed enough to filter it out effectively. While jaundice usually resolves on its own within a couple of weeks, it can sometimes be an indicator of a more serious underlying condition. So, does jaundice cause yellow poop in newborns?

Jaundice is caused by a build-up of bilirubin in the blood

Jaundice is a common condition in newborns, affecting around 60% of full-term babies and 80% of premature babies during their first week of life. It is caused by a build-up of bilirubin in the blood, which occurs when the liver is unable to process and remove it from the body. Bilirubin is a yellow substance produced when the body breaks down old red blood cells. While this is a normal process, newborn babies often experience a build-up of bilirubin because their livers are not yet fully developed.

In adults, jaundice is rare and is typically a sign of an underlying health issue. It can be caused by a variety of factors, including liver dysfunction, blood disorders, hepatitis, alcohol-related liver disease, gallstones, cancer, or certain medications.

There are different types of jaundice, depending on the underlying cause and the part of the body affected:

• Prehepatic jaundice occurs when there is a breakdown of red blood cells, resulting in increased bilirubin production before it enters the liver.
• Hepatic jaundice is caused by abnormal liver metabolism of bilirubin due to liver damage or disease.
• Posthepatic or obstructive jaundice happens when there is a blockage in the bile ducts, preventing the flow of bile and leading to a build-up of bilirubin after it passes through the liver.

Jaundice can cause yellow discolouration of the skin and eyes, known as scleral icterus, when bilirubin levels exceed 3 mg/dL. It can also lead to pale stools, dark urine, and itching.

Treatment for jaundice depends on the underlying cause. Mild cases may resolve on their own, while more severe cases may require medical intervention, such as phototherapy or, in rare cases, surgery.

Bilirubin is a yellow substance produced when red blood cells break down

Jaundice is a common condition in newborns, characterised by a yellowing of the skin and eyes. It is caused by a buildup of bilirubin in the blood. Bilirubin is a yellow substance produced when red blood cells break down. When red blood cells reach the end of their life cycle, they break down and pass through the bloodstream to the liver for processing. The liver then sorts bilirubin with other waste products into a fluid called bile. This fluid exits the body through the intestines. Bilirubin is the pigment that gives bile its distinctive yellow colour. It also colours your stool.

In adults, the liver typically filters bilirubin from the blood. However, newborn babies have livers that are not yet fully developed, and so they may not be able to filter out the bilirubin effectively. This can lead to a buildup of bilirubin in the blood, causing jaundice.

Jaundice usually appears between 2 and 7 days after birth. As the amount of bilirubin in the blood builds up, the baby's body will become more yellow. This yellowing typically starts in the baby's head and can move down to the chest and even the toes.

While jaundice is usually not serious and often goes away on its own within a couple of weeks, it is important for a healthcare provider to check the baby for jaundice. Severe jaundice can lead to brain damage if left untreated. Treatment for jaundice may include phototherapy, where the baby is placed under special blue lights to help the liver break down the bilirubin. In rare cases, an exchange transfusion may be necessary, where some of the baby's blood is replaced with fresh, donated blood.

Jaundice is very common and usually harmless

Jaundice is a common condition in newborns, affecting up to 60% of full-term babies and 80% of premature babies during their first week of life. It is caused by a buildup of bilirubin in the blood, which occurs when the liver is not fully developed and cannot effectively remove bilirubin from the body. Bilirubin is a yellow substance produced during the breakdown of red blood cells. While jaundice can make a newborn's skin and eyes appear yellow, it is usually harmless and resolves on its own within a couple of weeks.

Types of Jaundice

There are several types of jaundice that can affect newborns, including:

• Physiological jaundice: This is the most common type of jaundice, affecting 50% of newborns. It is considered normal and typically resolves within two weeks without treatment.
• Prematurity jaundice: Premature babies often have livers that are not developed enough to break down bilirubin effectively, so they are often treated even if their bilirubin levels are not too high.
• Breastfeeding jaundice: This type of jaundice occurs when a baby does not get enough breast milk, leading to dehydration or low calorie intake. It can affect up to 10% of infants and usually occurs during the first week of life.
• Breast milk jaundice: Substances in breast milk can affect how a baby's liver breaks down bilirubin, causing a buildup. This type of jaundice may appear after the first week of life and can take a month or longer to disappear.

Symptoms of Jaundice

The main symptom of jaundice is the yellowing of the skin and eyes. It usually appears within the first few days of life and can be more difficult to detect in babies with darker skin tones. Other symptoms may include dark, yellow urine and pale-coloured poop.

Treatment of Jaundice

In most cases, jaundice does not require treatment and will resolve on its own within one to two weeks. However, in some cases, treatment with phototherapy or exchange transfusion may be necessary to reduce the risk of brain damage caused by high levels of bilirubin.

Jaundice can be harder to spot in darker skin tones

Jaundice is a common condition in newborns, causing a yellowing of the skin and eyes due to a buildup of bilirubin in the blood. While jaundice usually clears up within a couple of weeks, severe cases can lead to brain damage if left untreated.

In darker-skinned individuals of all ages, jaundice may be more noticeable in the whites of the eyes, but this could also be due to benign causes, such as aging or exposure, which can cause the conjunctiva (the thin protective layer over the sclera) to degenerate and appear more yellow or brown. This is more common in people with melanin-rich skin, such as those of African or Asian descent.

It is important for healthcare providers to be aware of these differences in presentation and to have access to resources that show what conditions like jaundice look like on a variety of skin tones. This can help ensure timely and accurate diagnoses, as well as proper treatment, for all patients.

Treatment for jaundice is rarely needed

Jaundice is a common condition in newborns, with about 60% of full-term babies and 80% of premature babies developing it during their first week of life. It is caused by a buildup of bilirubin in the blood, which occurs when the liver is not yet developed enough to filter and remove it from the body. While jaundice can make a baby's skin and eyes appear yellow, it usually isn't serious and often goes away on its own within 1 to 2 weeks. Mild jaundice typically doesn't require any treatment.

Treatment Options

In most cases, jaundice will resolve without treatment as the baby's liver matures and they are fed regularly. However, in more severe cases, treatment options may include:

• Phototherapy: This is the most common treatment for severe jaundice. The baby is placed under special blue lights with minimal clothing so that their skin is exposed to the light. The light helps break down the excess bilirubin, allowing it to be removed from the body. Phototherapy usually lasts for 1 to 2 days.
• Exchange transfusion: In rare cases where phototherapy is ineffective, an exchange transfusion may be necessary. This involves replacing some of the baby's blood with fresh, donated blood to lower bilirubin levels quickly.
• Intravenous immunoglobulin (IVIg) treatment: For babies with blood type incompatibilities, IVIg is administered through an IV to block antibodies that attack red blood cells and reduce the need for an exchange transfusion.
• Supplementing with formula: For newborns with breastfeeding jaundice, supplementing with formula can help lower the risk of jaundice.

Prevention

While jaundice cannot always be prevented, feeding a newborn frequently (8 to 12 times a day) in the first few days of life can help reduce the risk of developing jaundice. Regular feeding stimulates bowel movements, aiding in the removal of bilirubin from the body.
