Prompted by the ease and relatively low costs of travel, more patients from these countries are travelling to the developing world to access less-costly medical and surgical procedures, researchers said.
Because cosmetic plastic surgery procedures aren't covered by insurance, they make up a major part of the burgeoning medical tourism market.
India alone may have more than one million medical tourists per year, according to the study.
Other countries with growing medical tourism industries include Mexico, Dubai, South Africa, Thailand and Singapore.
Even after the costs of airfare are factored in, having an operation in these countries can be much less expensive.
The trend is having an impact on the market for cosmetic plastic surgery, according to an article in Plastic and Reconstructive Surgery-Global Open, the official medical journal of the American Society of Plastic Surgeons (ASPS).
"The rapid globalisation of the industry also marks a fundamental shift in the world's perception of elective procedures: patients are becoming consumers and these medical services are being viewed as commodities," Dr Kevin C Chung and Lauren E Franzblau of the University of Michigan, said.
In many countries, governments are working actively to foster their medical tourism industry. Some destinations even market procedures performed in resort-like settings, encouraging patients to combine a vacation with cosmetic surgery, they said.
Travelling abroad also lets patients recuperate privately, without anyone at home knowing that they've had plastic surgery, researchers noted.
The growth of medical tourism may have a significant impact on the cosmetic surgery market in the US, but also raises concerns over physical safety and legal protection.
"Because the practice of medical travel does not appear to be going away in the foreseeable future, plastic surgeons must understand the international market and learn to compete in it," Chung and Franzblau said.
