Travelling to other countries to avail medical services comes under Medical Tourism. People generally opt other countries for treatment owing to the less treatment charges or better facility options in other countries.
Medical tourism is now big business especially in developing countries such as Thailand, India and many South American countries. Even countries such as Malaysia and Singapore attract a lot of medical tourists due to high standards of medical care available.
As per many surveys, medical tourists travel to obtain services ranging from simple dental and medical procedures to more complex treatments such as invasive surgeries, alternate medicine such as Ayurveda etc.
The availability of highly qualified medical professionals, international standard infrastructure, English as a common language and cost effectiveness of treatments is what attracts many medical tourists to developing countries to obtain medical services.
