Thailand

Thailand is known for its meticulous cosmetic surgery, including gender reassignment. Up to 1.2 million individuals traveled to the south-east Asian country in 2013, according to Patients Beyond borders.

The Thai capital of Bangkok is home to one of the world's best known hospitals for medical tourists, Bumrungrad International, which has been seeing foreign patients for 20 years. It has over 900 physicians across 55 specialities and sees around 1,000 international patients every day.

Treatment in Thailand comes at 50-70 percent of the cost in the U.S. — and up to 30,000 American health tourists travel there each year, according to the Medical Tourism Research Guide. Bumrungrad International prices a nose job at 169,000 Thai bahts ($5,205) on its website.
