Traditionally, "difficult patients" have often been blamed for presenting particular challenges in medical communication. However, growing evidence suggests that many such difficulties stem from discrepancies in expectations, perceptions, and values between healthcare professionals and patients. This paper explores the core issues of doctor-patient communication and analyze how healthcare marketization impacts physicians’ professional autonomy and their relationship with patients. Communication in healthcare involves not only information transmission but also emotionally charged and ethically complex interactions. While the trend of marketization has prompted healthcare institutions to emphasize patient satisfaction, reducing healthcare into a service business risks exacerbating doctor-patient conflicts and compromising professional judgment and the rational allocation of medical resources. Medical practice differs fundamentally from general market transactions in that it is grounded in evidence-based medicine and professional ethics, rather than solely driven by patient/customer demands. In this context, healthcare professionals must balance empathy with professional boundaries to ensure both the scientific integrity of clinical decisions and the stability of the doctor-patient relationships. This paper further examines how medical education and clinical practice can support professionals in delivering compassionate care while avoiding emotional overload, preventing burnout, and developing sustainable coping strategies to enhance the overall quality of healthcare services, particularly in the communication with and care of older adults. Future research should prioritize more localized empirical studies to delve into communication challenges and solutions across diverse clinical settings, enabling healthcare professionals to achieve a workable balance between professional autonomy and patient needs, ultimately advancing patient-centered, holistic care.
