About Deia Health

Deia Health, founded by Dr. Lafina Diamandis, offers a transformative blend of modern medicine and holistic wellbeing. The clinic is built on the belief that true health goes beyond symptom management, focusing instead on uncovering the root causes of illness. By combining evidence-based medicine with nutrition, movement, sleep, and stress management, Deia Health creates personalised care plans designed to support long-term wellbeing.

Each programme is carefully tailored, bringing together precision diagnostics, laboratory testing, and genetic insights with holistic interventions such as gut-directed yoga and somatic healing. This integrative approach harmonises science and soul, helping patients achieve meaningful, sustainable health improvements.

Located at 9 Harley Street, Deia Health provides private GP consultations, health screening, functional and lifestyle medicine assessments, and comprehensive health programmes. The clinic’s multidisciplinary team includes dietitians, functional medicine practitioners, psychologists, therapists, and coaches, all working collaboratively to guide and support each patient. Whether in person or online, Deia Health offers a safe and compassionate space to pause, reset, and prioritise health, empowering individuals to take control of their wellbeing and longevity.

Very helpful and caring doctor. I missed my appointment due to an accident. The team was very helpful to rebook me for another appointment and I was not charged for the appointment even when I did want to pay. Lafina is a valuable asset to society and to all our lives because of her medical knowledge and caring attitude to others.

Firstly, I would like to say that writing this review was very hard for me, because it brings a few tears to my eyes. I described Dr Lafina as irreplaceable valuable asset to society and to all our lives, because Lafina has made a profound positive impact through her work and kindness. Lafina has a special energy in her that innovates and motivates people, turning struggles into a message that helps others thrive in life. This special, irreplaceable energy that feeds the soul is priceless. It nurtures our well-being and cannot be bought or replaced. Lafina founded DEIA Health just for us, so we can all enjoy a good health and access support. This is the only medicine and support I can't get from anywhere else in the world, it is priceless. I just wish my health was better and I had the ability to seek more help and support from Dr Lafina.

Dr Lafina is a thoughtful and knowledgeable doctor who supported me through challenging perimenopause symptoms and digestive issues. She brought the right expertise to properly diagnose and address my concerns, and I’m now well on my path to healing.

As always a great experience visiting the Deia Health clinic and seeing Dr Lafina. My recent visit was a follow up appointment to my the regular health screenings I get with Deia Health. Was great as I had some big improvements in blood markers that we were working on improving, Lafina was great in helping me come up with a strategy to improve particular markers. So super happy with recent visit
