Texas Nurse Sarah Danh Airlifted Back to U.S. After Suffering Liver Failure on Japan Honeymoon With Husband Luke Gradl, Cause of Life-Threatening Illness Unknown

A Texas nurse is fighting for her life after being airlifted back to the United States with a life-threatening illness that began just days into her honeymoon in Japan.

Sarah Danh, 27, a labor and delivery nurse from San Antonio, Texas, was rushed back to the U.S. after suffering a sudden and severe medical emergency while traveling abroad with her husband, Luke Gradl, 28.

The newlyweds had tied the knot on March 21 in Houston’s Spring Branch neighborhood in what Gradl described as their “dream wedding” before departing for Tokyo on April 8 to begin their honeymoon.

However, the trip quickly took a devastating turn.

“When we arrived at the hotel the afternoon of April 8, she was not feeling well, so we decided to rest,” Gradl said. “We had 16 days planned, so we thought we could afford to take it easy.”

By the following day, Danh’s condition rapidly deteriorated.

“April 9, things started to go bad very quickly,” Gradl explained. “I immediately took her to the hospital just before midnight. She was admitted to the emergency room and then moved to the ICU the next day because of life-threatening health decline.”

Danh began experiencing alarming symptoms, including jaundice, severe body aches, and persistent vomiting. Doctors in Japan later diagnosed her with acute liver failure. Gradl said her condition was further complicated by kidney failure and increased pressure on the brain, describing the ordeal as “a test like no other.”

Despite extensive testing, the exact cause of her sudden illness remains unknown. Gradl emphasized that his wife showed no signs of being unwell before the trip.

After spending days hospitalized overseas, Danh was transported back to the United States on a specialized medical flight — a grueling 20-hour journey that included multiple refueling stops. Video footage showed her strapped to a gurney as she was carefully loaded onto the aircraft.

Family members acknowledged the risks involved in such a long-distance medical transfer but said it was necessary to give her the best chance at survival.

 

Now back in San Antonio, Danh is awaiting a possible liver transplant, with a U.S. transplant team on standby as doctors continue to monitor her condition.

Danh works at Methodist Stone Oak Hospital, where colleagues and loved ones have rallied around her during the crisis. A GoFundMe organized by family friend Danniella Ongmanchi has raised more than $178,000 to help cover mounting medical expenses.

“Being away from home during such a vulnerable time has been incredibly difficult for Sarah and her husband, Luke, as they try to navigate the uncertainty and worry together,” Ongmanchi said.

Gradl’s family has also played a critical role, assisting with communication between doctors in Japan and the United States during the emergency.

“I don’t know how we would have survived without them,” Gradl’s family shared.

As Danh continues her fight for survival, her case remains both urgent and uncertain, with doctors still working to determine what triggered the sudden and severe medical crisis.
