Dr Hasnat Khan is a British-Pakistani cardiothoracic surgeon who became internationally famous because of his relationship with Diana, Princess of Wales. While much of the public knows him through that connection, his professional career is much broader. He spent decades working in the United Kingdom as a heart and lung surgeon and built experience at major medical institutions.
Dr Hasnat Khan is again receiving attention for a professional reason. After years of medical work in the United Kingdom, he returned to Pakistan and took a senior position at the Jinnah Institute of Cardiology in Lahore. His return has renewed interest in his age, education, medical specialty, family background, relationship with Princess Diana, and present-day career.
Who Is Dr Hasnat Khan?
Dr Hasnat Khan is a Pakistani-born cardiothoracic surgeon who developed much of his professional career in the United Kingdom. He was born in Jhelum, Punjab, Pakistan, and later moved to Britain for advanced medical training. His specialist field involves surgery of the heart, lungs, and other organs and structures within the chest.
Khan became internationally recognizable in the 1990s because of his relationship with Diana, Princess of Wales. However, his medical career has remained the central part of his professional life. He has generally avoided celebrity attention and has maintained a reputation for being a private and reserved person.
How Old Is Dr Hasnat Khan?
Dr Hasnat Khan was born in 1958, making him 68 years old. His exact birth date is sometimes reported differently across online biographies, so his year of birth is the safer detail to use when discussing his age.
At 68, Khan has already completed several decades of work in medicine. His career has included specialist surgical training, clinical work in Britain, involvement in international healthcare projects, and senior leadership responsibilities. His current role in Pakistan represents another major stage in that long professional journey.
Dr Hasnat Khan’s Education and Medical Training
Khan received his early medical education in Pakistan before moving to the United Kingdom to continue his specialist training. He developed his career in cardiothoracic surgery, a demanding area of medicine that requires extensive training and practical experience.
His British career included work at respected cardiac and thoracic institutions, most notably the Royal Brompton Hospital in London. His professional experience at major specialist centres helped him develop expertise in complex heart and lung surgery and gave him international exposure within the medical field.
What Does Dr Hasnat Khan Specialize In?
Dr Hasnat Khan is a cardiothoracic surgeon. This medical specialty focuses on surgical treatment involving the heart, lungs, and chest. Cardiothoracic surgery is a highly specialized field that can involve complex procedures for serious cardiovascular and respiratory conditions.
His professional identity has therefore always been connected primarily to medicine rather than celebrity. Even when his relationship with Princess Diana attracted worldwide media attention, Khan continued working as a surgeon. He did not use his connection with the royal family to establish a career in entertainment or public relations.
Dr Hasnat Khan and Princess Diana
Dr Hasnat Khan met Diana in 1995 while working at the Royal Brompton Hospital in London. Diana visited the hospital in connection with someone receiving treatment, and the two eventually became acquainted. Their relationship developed privately during a period when Diana’s personal life was already receiving intense media attention.
Their relationship lasted roughly two years, from 1995 until 1997. Diana was reportedly deeply attached to Khan and considered the relationship seriously. The couple’s private romance later became one of the most discussed relationships in the story of Diana’s life, particularly because Khan was one of the few people around her who was not seeking fame or publicity.
Why Did Hasnat Khan and Princess Diana Separate?
The relationship between Khan and Diana faced major practical challenges. Diana was one of the most famous women in the world, while Khan was a private doctor who valued a normal professional and personal life. The enormous difference between their public circumstances made a long-term relationship difficult.
Privacy was reportedly one of the biggest concerns. Khan understood that a marriage to Diana would expose his personal and professional life to constant media attention. Cultural and family differences also added complications, particularly because Diana reportedly considered the possibility of living in Pakistan.
Their relationship ended in 1997, shortly before Diana’s death in a Paris car crash on August 31 of that year. Khan later spoke about aspects of their relationship, but he generally maintained his preference for privacy. His reluctance to discuss their romance extensively has contributed to the enduring mystery surrounding their time together.
Was Dr Hasnat Khan Married After Diana?
Following his relationship with Diana, Khan later married Hadia Sher Ali, who came from a prominent Pakistani family. Their marriage did not last permanently, and they eventually separated. As with much of Khan’s personal life, detailed information about the marriage has remained limited.
The public interest in his later relationships has largely been driven by his connection to Diana. However, it is important to distinguish documented information from celebrity speculation. Khan has generally avoided discussing his private relationships in detail, and many claims about his personal life have been repeated online without strong confirmation.
Where Is Dr Hasnat Khan Now?
Dr Hasnat Khan returned to Pakistan after many years of working in the United Kingdom. He was appointed to a senior leadership role at the newly established Jinnah Institute of Cardiology in Lahore. Reports describe him as serving as the institution’s dean and chief executive, giving him responsibility in both medical and administrative areas.
His return represents a significant development in his career. After spending decades gaining experience in Britain’s healthcare system, he is now bringing that international experience back to Pakistan. The new cardiac institute is intended to strengthen access to specialized heart treatment in Lahore and provide advanced medical services.
Khan’s appointment has also changed the public conversation around him. For many years, he was primarily associated with Princess Diana. His return to Pakistan has placed his medical expertise and leadership abilities at the centre of renewed public attention.
Dr Hasnat Khan’s Medical Career and Achievements
Khan’s career includes years of experience at major British cardiothoracic centres. His work at institutions such as the Royal Brompton Hospital helped establish him as an experienced heart and lung surgeon. He has also been associated with international healthcare development and medical projects outside Britain.
His professional journey is particularly notable because he built his reputation in a demanding medical specialty while remaining largely outside the public spotlight. Unlike many people who become famous through a connection with royalty, Khan did not turn his association with Diana into a celebrity career.
His medical work has also allowed him to contribute to healthcare beyond individual surgical practice. His current leadership position in Lahore gives him an opportunity to use his international experience to help develop cardiac services, medical standards, and specialist healthcare infrastructure in Pakistan.
Dr Hasnat Khan’s Life and Public Image
At 68, Dr Hasnat Khan remains a respected medical professional whose career has crossed two countries. His life combines a long history in British medicine with a new chapter in Pakistan’s healthcare sector. His appointment at the Jinnah Institute of Cardiology has given his professional career fresh importance.
His public image remains closely connected to Princess Diana, but that is only one part of his biography. Khan’s decades of medical training and surgical work represent the larger part of his professional life. His ability to maintain privacy despite worldwide interest in his relationship with Diana is another defining characteristic.
The decision to return to Pakistan is particularly significant because it brings his experience back to the country where he was born. Rather than remaining permanently associated with his past in Britain, Khan is now taking on a leadership role in a developing cardiac institution in Lahore. This gives his career a new direction and potentially allows him to influence the future of specialist heart care in Pakistan.

Conclusion
Dr Hasnat Khan is a British-Pakistani cardiothoracic surgeon who became famous worldwide because of his relationship with Diana, Princess of Wales. Born in Jhelum in 1958, he built a distinguished medical career in the United Kingdom and spent many years working in specialist cardiac and thoracic medicine.
His relationship with Diana lasted from 1995 to 1997 and became one of the most closely examined romances of her life. Despite the enormous public interest, Khan remained committed to privacy and continued to focus on his medical career.
His story has entered a new chapter with his return to Pakistan and senior leadership role at the Jinnah Institute of Cardiology in Lahore. At 68, he continues to be associated with medicine, surgery, and healthcare leadership. While his relationship with Princess Diana will always be part of his public biography, his decades of medical work and his contribution to Pakistan’s cardiac healthcare sector are an equally important part of his legacy.
