A beloved nurse from Texas suffered acute liver failure on her honeymoon forcing her to fly home for emergency treatment, putting the newlywed couple's vows to the test just a week after they tied the knot. 

Sarah Danh, 27, was celebrating her wedding with her new husband, Luke Gradl, 28, in Japan when she suddenly fell critically ill and had to fly home for a liver transplant. 

The newlyweds left on April 7th and had only been on their dream honeymoon for around 48 hours when Danh was rushed to the emergency room and diagnosed with acute liver failure. 

'When we arrived at the hotel the afternoon of April 8, she was not feeling well. So, we decided to rest that day because we had 16 total days in Japan, so we could afford to rest half a day,' Gradl told People. 

'April 9 things started to go bad very quickly, so I immediately took her to the hospital just before midnight where we were admitted to the emergency room, and the next day moved to the ICU because of life-threatening health decline.'

According to Gradl, Danh began to suffer from jaundice, vomiting, fever, body aches and 'extreme' hepatic encephalopathy; a serious decline in brain function caused by severe liver disease. 

'There were no health signs at our wedding,' the newlywed added. 

While miles away from her family, the labor and delivery nurse was admitted to an intensive care unit in Japan where she endured blood and platelet transfusions, according to a GoFundMe. 

The fundraiser, which garnered over $165,000 in donations, was created to help raise funds for medical expenses; as, in Japan, hospital bills must be paid in full or any treatments would stop. 

'She is on 24/7 CRRT (continuous renal replacement therapy), dialysis, blood transfusions and plasma exchanges,' Gradl added.  

On Monday, Danh was being prepped for the long flight home to Texas. Her uncle, Khang Le, said the journey was the 'most critical part of her recovery.'

Danh was seen in a video shared by her uncle unconscious and lying on a stretcher, surrounded by medical and airport staff on the runway awaiting to board her flight home. 

'She will be on a 20+ hours flight including three refueling stops... Although both the Japanese and American medical staff came together to prepare Sarah for this long trip back, but the risk is still incredibly high,' he wrote on Facebook.

'The medical staff have been doing an incredible job to prepare Sarah back to a condition that would minimize the risk of mid air emergency. However, there is still a non zero. In my mind, this risk [is] worth taken if we want her to have any chance of recovery, let alone be normal again.'

Danh's mother, Le Le, arrived to be by her daughters side on April 13 to support Danh and Gradl 'in any way she can,' Khang Le wrote. 

'We are so thankful for all the love, support and kind words everyone has shown,' Le Le said in a post on Facebook. 

'Although Sarah is fighting for her life in the ICU, we truly believe she can feel all the prayers and strength being sent her way.'

'The past few days have been incredibly difficult for our family and for everyone who knows Sarah,' her brother Nate wrote on Facebook. 

'This has all come as a complete shock to us, as Sarah has never shown any prior signs or symptoms of liver issues. Watching her go through this so suddenly has been devastating for her, for Luke and for our entire family.' 

Danh's family and her new husband asked everyone to continue praying for her as she makes her way home to continue recovery. 

'With her story I just want as many people to be aware and provide prayer,' Gradl told People. 

'I just want her to be stable enough for our evacuation that is being coordinated through AirMed because it is a long, risky flight that must be done to get her home.'

Gradl, who is currently training to be a pilot, said they continue to put their faith in God and the medical staff caring for Danh. 

'I love my wife with all my heart and this is a test like no other.'

The Daily Mail reached out to Danh's family and Luke Gradl for comment.
