Dr. Vijay Viswanathan, Chief Physician and Chairman & Managing Director of M.V. Hospital for Diabetes Pvt. Ltd., has spent decades looking beyond blood sugar levels to address the wider challenges of diabetes through clinical care, research, prevention, and innovation.
His work across diabetic foot care, multidisciplinary treatment, research, and emerging technologies has been shaped by one clear priority: to identify problems early, prevent complications, and give patients the care they truly need.
Dr. Vijay’s leadership goes beyond managing a healthcare institution. He has focused on building a culture where doctors and teams work together, new ideas are welcomed, and advances in medicine translate into better care for patients.
A Journey Shaped by Legacy and a Commitment to Better Diabetes Care
Dr. Vijay’s journey in diabetes care began at home. His father, Prof. M. Viswanathan, Founder of MV Diabetes and one of the pioneers of diabetology in India, played a defining role in shaping his career. At a time when much of the country’s healthcare attention was focused on communicable diseases, his father recognized diabetes as a growing challenge. He dedicated his life to building awareness, advancing research, and improving patient care.
That early influence stayed with Dr. Vijay Viswanathan as he built his own career. Over the years, he developed a particular interest in diabetic neuropathy and, more specifically, in preventing and managing diabetic foot complications. Seeing patients struggle with foot ulcers and, in severe cases, face amputation made the need for early detection and prevention very real to him. It also reinforced the importance of bringing different medical specialists together to provide complete care.
His work in diabetic nephropathy became another important part of this journey. He was the first in India to obtain a PhD in the field, reflecting his long-standing interest in preventing kidney complications and protecting the health of people living with diabetes.
While his areas of expertise have grown over the years, the purpose behind his work has remained simple: to help people with diabetes live healthier lives and avoid the complications that can so profoundly affect their quality of life.
Reimagining What Diabetes Care Can Be
Diabetes rarely arrives as a single problem. Over time, it can affect the nerves, kidneys, heart, feet, nutrition, lifestyle, and even a person’s emotional well-being. For Dr. Vijay, that reality has shaped the way he believes diabetes should be treated.
At M.V. Hospital for Diabetes, the focus has never been limited to bringing down blood sugar levels. The larger goal has been to understand the individual behind the condition and address the many factors that influence their health. This philosophy has guided the institution’s growth and its approach to patient care.
The hospital has built its model around a 360-degree view of diabetes, bringing together clinical assessment, complication screening, nutrition, lifestyle management, psychosocial support, and preventive care. Having multiple areas of expertise working together allows treatment to be tailored to each patient rather than following a one-size-fits-all approach.
The value of this model is ultimately measured by what happens in a patient’s life beyond the hospital, Dr. Vijay Viswanathan considers. Detecting a complication early can prevent it from becoming life-altering. Helping someone understand their condition can give them greater confidence in managing it. And timely intervention can mean avoiding complications altogether.
This patient-first philosophy has helped M.V. Hospital for Diabetes at North Chennai build its reputation for comprehensive and evidence-based diabetes care. But the larger ambition remains unchanged: to make every clinical decision count toward helping people live longer, healthier, and better lives with diabetes.

| Patients needed better guidance on protecting their feet. | Introduced patient foot-care education and high-risk foot screening. | Greater awareness and prevention. |
| Complex wounds required advanced treatment. | Implemented advanced wound care and limb-salvage protocols. | Improved limb preservation. |
| Diabetic foot complications threatened mobility and quality of life. | Sustained the dedicated program for 28 years. | 90,000+ limbs saved from amputation. |
Turning Research into Real-World Diabetes Care
Research has always been closely tied to the work at M.V. Hospital for Diabetes, not as an exercise in discovery alone, but as a way to change what happens to patients in everyday care. Over the years, this commitment has led to several initiatives focused on prevention, early detection, complication management, and access to treatment.
One of the early steps was the creation of a dedicated Prevention Department, built around the idea that identifying diabetes before it progresses can make a lasting difference. Since diabetes often runs in families, the hospital introduced counselling for siblings and other family members of people with diabetes, along with free Glucose Tolerance Tests (GTT) to help identify those at risk and encourage timely intervention.
The same focus on access extends to children living with Type 1 diabetes. Through a program providing free insulin, the hospital has worked to ensure that the cost of treatment does not stand between a child and the medication they need to live.
Complication prevention has been another important area of work. The “Save the Feet” national-level project, implemented with the National RSSDI (Research Society for the Study of Diabetes in India), focuses on preventing diabetic foot complications and improving limb-salvage outcomes. The hospital has also worked on the early identification of kidney damage using estimated Glomerular Filtration Rate (eGFR), enabling earlier intervention and more timely renal care.
Together, these initiatives reflect a consistent approach for Dr. Vijay Viswanathan: take what research and evidence reveal, turn it into practical healthcare programs, and make prevention and treatment more accessible to the people who need them most.

Leading Through People, Purpose, and Trust
A healthcare institution can have the best technology and clinical expertise, but its success ultimately rests with the people who deliver care every day. That belief has shaped Dr. Vijay’s approach to leadership.
His philosophy is rooted in leading by example, giving teams the confidence to take ownership, and creating an environment where people feel trusted and valued. In a field that changes constantly, he believes an institution can only keep moving forward when its people are willing to learn, adapt, and work toward a common purpose.
Open communication and mutual respect are an important part of that culture. At M.V. Hospital for Diabetes, every person has a role to play in the patient’s journey, from clinicians and nurses to technicians and support staff. Each contribution matters when the goal is to deliver better care.
This mindset has helped build a culture where innovation and collaboration are part of everyday practice. The hospital continues to invest in education, embrace new technologies, encourage research, and strengthen evidence-based practices while keeping patient needs at the center.
Dr. Vijay Viswanathan sees leadership not as directing people from the top, but as bringing the right people together, helping them grow, and giving them the freedom and responsibility to do their best work. When that happens, innovation becomes part of the culture, and better patient care becomes the shared goal.
Shaping the Next Generation of Diabetes Care Leaders
A healthcare institution’s legacy is not built only through its achievements. It is also measured by the people it prepares to carry that work forward. That belief has made education, training, and mentorship an important part of Dr. Vijay’s vision at M.V. Hospital for Diabetes.
The hospital provides structured courses, fellowship programs, and hands-on training for young physicians, researchers, nurses, and allied healthcare professionals. The aim is to give them more than clinical knowledge; it is to prepare them to handle the realities of modern diabetes care.
Trainees gain experience in managing routine diabetes as well as complex complications such as diabetic foot disease, kidney disease, and other multisystem disorders. Just as importantly, they are encouraged to understand the value of compassionate, ethical, patient-centered, and multidisciplinary care.
The hospital’s research institute adds another dimension to this learning. Through national and international collaborative research projects, young professionals are exposed to emerging technologies, scientific developments, and evidence-based practices.
Dr. Vijay believes tomorrow’s diabetes leaders need more than medical expertise. Scientific curiosity, lifelong learning, teamwork, compassion, and a genuine desire to improve patients’ lives will be essential qualities for those shaping the future of diabetes care.
Building the Next Chapter of Diabetes Care Through Collaboration
Growth in healthcare is rarely achieved alone. At M.V. Hospital for Diabetes, collaboration has become an important part of Dr. Vijay’s vision for taking diabetes care forward.
The hospital has built partnerships with national and international academic institutions, research organizations, healthcare providers, and industry partners. These relationships have opened doors to meaningful research, new technologies, and stronger clinical, academic, and research capabilities.
Several collaborative research projects are already underway, with a focus on diabetes prevention, early diagnosis, and the management of diabetes-related complications. New collaborations are also in the pipeline, creating opportunities to expand research, clinical services, and academic activities.
Partnerships with institutions such as Stanford University, IIT Madras, and Vaishnav College are part of this wider effort. Beyond sharing expertise, these collaborations are intended to encourage knowledge exchange, support innovation, and help move research findings into practical patient care.
The long-term ambition is clear: to build a globally recognized centre of excellence where clinical care, research, education, and technology come together. Strengthening existing relationships while building new ones will help make advanced, evidence-based diabetes care more accessible and continue raising the standard of healthcare delivery.
Rethinking India’s Fight Against Diabetes
Dr. Vijay Viswanathan has spent decades witnessing how delayed diagnosis and poor diabetes management can affect lives. He believes India’s growing diabetes burden cannot be addressed by focusing only on blood sugar levels. Diabetes can progressively damage the heart, kidneys, eyes, nerves, and feet, yet its seriousness is still underestimated.
Stronger public awareness about diabetes, its risk factors, and long-term complications must become a priority. With unhealthy diets, physical inactivity, obesity, stress, and poor sleep contributing to lifestyle-related diseases, prevention, regular screening, and healthier habits need greater attention.
Dr. Vijay also highlights the consequences of poor treatment adherence and irregular follow-ups, which can lead to serious complications and place greater financial pressure on patients, families, and the healthcare system.
His vision focuses on early detection, patient education, multidisciplinary care, affordable treatment, and community-based prevention. The priority is to move from treating complications to preventing them and build a healthier future for India.
A Legacy That Lives Through Better Care
Dr. Vijay Viswanathan hopes to leave behind a legacy built on compassionate care, clinical excellence, research, education, and innovation. He believes research is essential to advancing diabetes prevention, diagnosis, and treatment, and encourages every healthcare professional to contribute to generating evidence that improves patient outcomes.
His message to aspiring healthcare leaders is simple: never stop learning. Medicine is constantly changing, and staying current with new technologies and evidence-based practices is essential to delivering better care.
Above all, he believes that progress in medicine must never come at the cost of compassion. When scientific curiosity, continuous learning, and empathy come together, healthcare can create a lasting difference in the lives of patients and future generations.
Success Code
The one principle that has guided me throughout my journey is that care and compassion are the foundation of excellent patient management. While medical knowledge and technology continue to evolve, patients always remember how they were treated with empathy, respect, and genuine concern. Equally important is the commitment to continuously upgrade clinical practice by embracing evidence-based medicine, advanced technologies, and innovative treatment approaches. Providing sophisticated, high-quality care not only improves clinical outcomes but also builds confidence and trust among patients. When compassion is combined with clinical excellence and a commitment to continuous learning, it creates a lasting impact on both patients and the healthcare profession.
