Jaundice treatment depends entirely on what’s causing it. In newborns, the most common approach is phototherapy, which uses specific wavelengths of light to break down excess bilirubin so the body can excrete it. In adults, treatment targets the underlying condition, whether that’s a blocked bile duct, liver disease, or an infection. The yellowish tint in the skin and eyes is a symptom, not a disease itself, so resolving it means fixing whatever is driving bilirubin levels up.
How Phototherapy Works for Newborns
Most newborn jaundice clears on its own within two weeks. When bilirubin levels climb high enough to need intervention, phototherapy is the first-line treatment. Blue light in the 460 to 490 nanometer range penetrates the skin and triggers a chemical change in bilirubin molecules. Normally, unconjugated bilirubin is fat-soluble, meaning the body can’t easily flush it out through urine or stool. Light exposure rotates parts of the bilirubin molecule, breaking the internal bonds that keep it locked in its fat-soluble shape. This exposes the molecule to water, making it soluble enough to be excreted without the liver needing to process it first.
The most readily excreted form created during phototherapy is called lumirubin, a structural rearrangement of bilirubin that the body eliminates quickly through bile and urine. This is why phototherapy can lower bilirubin levels within hours, though most babies stay under the lights for one to two days.
In the hospital, babies are placed under overhead blue LED panels wearing only a diaper and protective eye shields. The goal is to expose as much skin as possible to maximize light absorption. Babies are typically kept under the lights continuously, with breaks only for feeding.
Home Phototherapy With Fiberoptic Blankets
When bilirubin levels are elevated but not dangerously high, some families can continue phototherapy at home using a fiberoptic light pad, sometimes called a bili blanket. The pad emits therapeutic light from beneath the baby, who lies directly on it wearing only a diaper. The baby’s eyes still need protective covering, and the pad should stay in use as close to 24 hours a day as possible for the best results.
One advantage of these blankets is flexibility. You can hold and feed your baby while the treatment continues, and the baby can even lie skin to skin on your chest with the blanket draped over their back. A thin cotton swaddle goes around the baby while they remain on the pad. Your pediatrician will schedule follow-up blood draws, typically daily, to confirm bilirubin is dropping as expected.
Exchange Transfusion for Severe Cases
When bilirubin levels are dangerously high or rising too fast despite phototherapy, exchange transfusion becomes necessary. This procedure gradually replaces the baby’s blood with donor blood, physically removing bilirubin from the circulation. A full exchange uses about 160 mL per kilogram of body weight, which replaces roughly 85% of the baby’s circulating blood. For less stable infants, a smaller single-volume exchange of 80 mL per kilogram replaces about 60%.
The procedure requires continuous heart and lung monitoring. Clinicians track every milliliter removed and infused, and lab work is checked at the halfway point, immediately after, and four hours later. Risks include drops in blood sugar, calcium levels, and body temperature, all of which the medical team actively monitors and manages. Exchange transfusion is uncommon but can be lifesaving when bilirubin reaches levels that risk brain damage.
Treating Obstructive Jaundice in Adults
When jaundice in adults results from a physical blockage in the bile ducts, such as a gallstone or a tumor pressing on the duct, treatment focuses on relieving that obstruction. The most common approach is placing a stent, a small tube inserted into the bile duct to hold it open and restore drainage. Stents can be placed endoscopically, meaning a flexible scope is passed through the mouth and into the digestive tract, or through the skin using imaging guidance.
Plastic stents have a diameter of 2 to 4 millimeters, while self-expanding metal stents open to about 10 millimeters. Metal stents last longer and require fewer repeat procedures, but they’re generally reserved for patients with inoperable cancers and a life expectancy under 6 to 12 months, since they’re difficult to remove once placed. Plastic stents are more commonly used for temporary drainage or when the underlying cause can be surgically corrected.
If the cause is gallstones, removing the gallbladder or extracting the stones endoscopically usually resolves the jaundice. For tumors, stenting may be combined with surgery, chemotherapy, or radiation depending on the type and stage of cancer.
Jaundice From Liver Disease
When jaundice stems from liver damage, whether from hepatitis, alcohol-related liver disease, or cirrhosis, the treatment targets the liver condition itself. There is no way to directly lower bilirubin in adults the way phototherapy does in newborns. Instead, the liver needs to recover enough function to process bilirubin on its own.
For viral hepatitis, antiviral medications can clear the infection and allow the liver to heal. For alcohol-related liver disease, stopping alcohol use is the single most important step. In advanced cirrhosis where the liver can no longer compensate, jaundice is one of several signs of decompensation, alongside fluid buildup in the abdomen and confusion from toxin accumulation. At that stage, management becomes supportive while evaluating whether a liver transplant is appropriate.
Diet and Hydration During Recovery
Regardless of the cause, supporting your liver through diet can help during jaundice recovery. Staying well hydrated is one of the simplest and most effective steps. Water helps the liver and kidneys flush out toxins and eases digestion. Aim for six to eight glasses of water daily, prioritizing water and nutrient-rich drinks without added sugars.
A balanced, fiber-rich diet supports liver function. Particularly helpful foods include:
- Colorful fruits and vegetables: berries, citrus fruits (especially lemons and grapefruits), beets, carrots, broccoli, spinach, and avocados
- Whole grains: oats, brown rice, quinoa, and whole wheat
- Healthy fats: nuts, olive oil, and oily fish like salmon and mackerel, which provide omega-3 fatty acids and zinc
- Lean proteins: tofu, legumes, poultry, and fish
Equally important is what to cut out. Alcohol should be avoided completely during jaundice recovery and often permanently if liver disease is involved. Refined carbohydrates like white bread, pasta, soda, and baked goods add stress to an already struggling liver. Packaged, canned, and smoked foods tend to be high in salt-based preservatives like nitrates and sulfates, which dehydrate the body and burden the liver. Fried and fast foods containing saturated and trans fats are harder for a compromised liver to process. Raw or undercooked shellfish carries a risk of hepatitis A and other infections that can worsen liver damage.
