Medical tourism has emerged as a rapidly growing segment of the global healthcare industry, with India becoming one of the leading destinations for international patients due to its cost-effective treatment, skilled healthcare professionals, advanced medical technology, and minimal waiting time. The changing healthcare paradigm, characterized by increased healthcare costs in developed countries and rising awareness of alternative treatment destinations, has significantly influenced the buying behaviour of international patients. The market has shown consistent growth, with millions of international patients visiting India annually for medical treatment, making it a major hub for medical tourism in Asia. This paper analyses the buying behaviour of international patients in India by examining key decision-making factors such as cost, quality of healthcare services, hospital accreditation, doctor expertise and availability of international patient services. The study also explores patient experience and satisfaction as crucial determinants of loyalty and repeat visits, as well as the challenges faced by medical tourists, including language barriers, cultural differences, and infrastructure issues. The research concludes that patient satisfaction and service quality are becoming the new competitive advantages in the medical tourism sector, shifting the focus from traditional healthcare delivery to patient-centred care and global healthcare marketing strategies.
