When untreated infant jaundice leads to kernicterus

On Behalf of | Oct 29, 2026 | Birth Injuries

Untreated infant jaundice can lead to kernicterus when bilirubin builds up to dangerous levels and injures the brain. In Michigan, that outcome may raise serious questions about whether the medical team failed to monitor, test or treat the newborn in time.

How does jaundice progress to kernicterus?

Jaundice happens when too much bilirubin builds up in a newborn’s blood. Mild cases often improve with monitoring or phototherapy. But if bilirubin keeps rising, it can reach the brain and cause permanent harm.

Doctors and nurses are generally expected to monitor bilirubin levels and respond to warning signs promptly. The Cleveland Clinic explains the lasting effects of bilirubin brain injury. Warning signs may include:

  • Extreme sleepiness.
  • Trouble waking for feeding.
  • High-pitched crying.
  • Arched back or body stiffness.
  • Weak feeding or poor sucking.

These signs can point to a medical emergency. Quick treatment may reduce further harm, but newborn care teams should catch rising bilirubin before the condition reaches that stage.

When can missed treatment support a malpractice claim?

A malpractice claim may arise if the medical team failed to follow accepted newborn care standards. That may include failing to check bilirubin levels, discharging the newborn without adequate follow-up in place or not responding when symptoms worsened.

In preventable newborn injury cases, the key records often include lab results, nursing notes, discharge timing and follow-up instructions. Those details can help show whether earlier treatment such as phototherapy or another intervention could have prevented brain damage.

Why the hospital record matters after a kernicterus diagnosis

Kernicterus can lead to long-term therapy, medical treatment and support needs. If you suspect a missed jaundice diagnosis or delayed treatment caused the injury, the hospital record may show when warning signs appeared and how the staff responded.

That timeline can shape both the medical case and the legal claim. A Michigan medical malpractice attorney can review the records, work with medical experts and help you assess whether preventable errors caused your child’s injury.
