How Light Therapy Works for Jaundice

Spread the love

Jaundice is a common condition that affects newborns, and it can be a cause of concern for parents. It is caused by an excess of bilirubin in the blood, which causes yellowing of the skin and eyes. Traditional treatments for jaundice include phototherapy, which involves exposing the baby to blue light, and exchange transfusion, which involves replacing the baby’s blood with donor blood. However, in recent years, light therapy has emerged as a promising alternative treatment for jaundice. In this article, we will explore the science behind light therapy and how it works for jaundice.

Jaundice is a common condition in newborns characterized by yellowing of the skin and eyes due to excess bilirubin in the blood. Light therapy, also known as phototherapy, is a commonly used treatment for jaundice in infants. In this process, blue or white light is shone on the baby’s skin to break down bilirubin and help it pass through the body more easily. This introduction will explore in more detail how light therapy works for jaundice treatment.

Understanding Jaundice

Before we dive into light therapy, let’s take a closer look at jaundice. Bilirubin is a yellow pigment that is produced when red blood cells break down. The liver is responsible for processing bilirubin and excreting it from the body. However, in newborns, the liver may not be fully developed, and the excess bilirubin may build up in the blood, causing jaundice.

Symptoms of jaundice include yellowing of the skin and eyes, dark urine, and pale stools. In most cases, jaundice is harmless and resolves on its own within a few weeks. However, in severe cases, it can lead to brain damage and other complications.

How Light Therapy Works

Light therapy, also known as phototherapy, is a treatment that involves exposing the skin to specific wavelengths of light. In the case of jaundice, the light used is blue light, which helps to break down the excess bilirubin in the blood.

During light therapy, the baby is placed under a special light that emits blue light. The light penetrates the skin and is absorbed by the bilirubin in the blood. As the bilirubin absorbs the light, it is converted into a form that can be excreted by the liver and eliminated from the body.

One key takeaway from this text is that light therapy, also known as phototherapy, is an effective alternative treatment for jaundice in newborns. It involves exposing the baby to specific wavelengths of blue light, which helps to break down excess bilirubin in the blood. Light therapy is non-invasive, less expensive than exchange transfusion, and can be done in the hospital or at home. It is also as effective as exchange transfusion in treating moderate to severe cases of jaundice. While generally safe, there are some risks associated with the treatment, and the baby’s temperature and fluid intake should be monitored during phototherapy.

Types of Light Therapy

There are two main types of light therapy used for jaundice: conventional phototherapy and intensive phototherapy.

One key takeaway from this text is that light therapy, also known as phototherapy, is a non-invasive and effective treatment for jaundice in newborns. It works by exposing the baby to blue light, which helps to break down excess bilirubin in the blood. There are two main types of light therapy: conventional phototherapy and intensive phototherapy. Phototherapy offers several benefits over traditional treatments for jaundice, and has a low risk of complications. However, it is important to monitor the baby’s temperature, fluid intake, and bilirubin levels during the treatment to prevent any potential risks.

Conventional Phototherapy

Conventional phototherapy involves exposing the baby to blue light for a certain period of time each day. The baby is usually placed under a special light that emits blue light, and their eyes are covered to protect them from the light. The length of treatment depends on the severity of the jaundice.

Intensive Phototherapy

Intensive phototherapy, also known as double phototherapy or triple phototherapy, is a more aggressive form of light therapy. It involves using two or three light sources at the same time to increase the intensity of the light. This type of therapy is usually reserved for severe cases of jaundice.

Benefits of Light Therapy

Light therapy offers several benefits over traditional treatments for jaundice. For one, it is non-invasive and does not require blood transfusions. It is also less expensive than exchange transfusion and can be done in the hospital or at home.

Light therapy is also effective at reducing bilirubin levels and improving jaundice symptoms. It has been shown to be as effective as exchange transfusion in treating moderate to severe cases of jaundice.

FAQs – How does light therapy work for jaundice?

What is jaundice?

Jaundice is a condition characterized by the yellowing of the skin and whites of the eyes. This happens when there is too much bilirubin in the blood. Bilirubin is a yellow substance that forms when the body breaks down old red blood cells. Normally, the liver processes bilirubin and eliminates it in the stool. However, when the liver is not functioning correctly, bilirubin builds up in the blood.

What is light therapy?

Light therapy, also known as phototherapy, is a treatment that uses light to help reduce the levels of bilirubin in the blood. During light therapy, the newborn is placed under a special type of light, called a phototherapy unit. The light interacts with the bilirubin in the baby’s skin, breaking it down into substances that can be eliminated through urine and stool.

How does light therapy work for jaundice?

Light therapy works by converting the bilirubin in the blood into a form that can be excreted from the body. The light used in phototherapy is of a specific wavelength that is absorbed by the skin and blood. This light causes a chemical reaction that changes the bilirubin molecule into a form that can be easily eliminated by the body.

How long does light therapy last?

The duration of light therapy depends on the severity of the jaundice and the age of the baby. In most cases, light therapy is administered for several days until the bilirubin levels in the blood decrease to a safe level. The baby’s bilirubin levels will be checked regularly during treatment to determine when the therapy can be stopped.

Are there any risks associated with light therapy?

Light therapy is a safe and effective treatment for jaundice, and serious complications are rare. However, there are some potential risks, including dehydration, overheating, and skin rash. Babies receiving light therapy are closely monitored to prevent these complications.

What happens after light therapy?

After light therapy is complete, the baby’s bilirubin levels will be checked to ensure that they have returned to a safe level. The baby may still appear slightly jaundiced for a few days, but this is normal and will resolve on its own. The baby will be able to go home once the bilirubin levels have returned to normal.
