Adelaide man stranded in Mexico after injury leaves him in a coma

An Adelaide man has been stranded in Mexico, after the trip of a lifetime went horribly wrong.

Ryan Maudlen, 33, has been in an induced coma since Wednesday when the globetrotter, who suffers from Crohn's disease, had a severe attack and his intenstine burst.

His partner Kati Reigl has only able to see him two hours a day.

"It's horrible to see someone you love so much," she said.

"He was just lying there he couldn't even cry any more he was in so much pain."

Ryan's father Robert said his son's existing condition prevented him from getting travel insurance.

The hospital is demanding US$13,600 (A$15000) a day for treatment and the bills are mounting up.

"I've drawn all the money I can from the bank. All up we're looking at about $100,000 so far that's been spent," Mr Maudlen said.

An online fundraiser has now been set up to save Ryan with $35,000 raised in just 3 days.

Mr Maudlen said even strangers had donated.

"Doesn't matter how much they've donated it's just the fact they've done it," he said.

Mr Maudlen is now putting the family home on the line to save his son, as the mounting medical bills have forced him to remortgage the house.
