Human beings do not have enough time to consult a doctor on a regular basis about their health because of their heavy workload and lack of time. It becomes difficult for the patients to visit multiple hospitals multiple times for their examination. With Healthcare 4.0 and fog computing a large quantity of information can be processed which can generate insights about the patient's health. By using fog computing real time monitoring of the patient's health can be achieved. It makes healthcare more effective, dependable, and convenient. Individuals can self-monitor their blood pressure, heart rate, and other vital signs and take preventive measures. The healthcare industry is a latency-sensitive area, as a result, fog computing deployment in this region is critical. Better care, better treatment, and higher patient satisfaction can result from proper analytics and analysis which can be done closer to end devices using Fog. This bibliometric research focusses on the current scenario, application of FC in Healthcare in India and its relevance in healthcare 4.0. This research aims to analyses how healthcare in India has integrated fog computing to enhance the quality of their services, the developments in recent times and what are the gaps in the research. A literature review will be conducted using the academic documents published in peer reviewed scientific journals, white papers, articles and secondary research will be used. [ABSTRACT FROM AUTHOR]
