After initially being treated at a hospital in Koh Samui he was later transported to the hospital in Bangkok to receive specialist treatment.
More than £200,000 had been raised in an online fundraiser to support his recovery.
The online fundraiser was set up by friends of Tiger’s family, who wanted to support them as they spent time at his bed side.
An update posted on the fundraising page said: “We want to thank everyone that has supported us in Tiger’s journey from prayers, messages and donations.
“Without those donations Tiger would not have reached his final destination where following his passing this morning in a selfless act has given three maybe four other people a second chance at life by donating his organs.
“We have had 19 days of living a nightmare, please now respect our peace and privacy.”
