Originally from the canton of Fribourg, Dr Pouya Iranmanesh obtained his Federal Diploma in Medicine from the University of Geneva in 2010.
He completed his internship in general surgery at the University Hospitals of Geneva (HUG), before pursuing his career as Head of Clinic at the HUG and in various hospitals in French-speaking Switzerland (Yverdon-les-Bains) and German-speaking Switzerland (Lucerne).
He obtained the title of FMH specialist in surgery in 2015, and the title of FMH specialist in visceral surgery (advanced training) in 2023.
He became interested in obesity surgery and robotic surgery early on in his training, and spent two years in the United States and Canada perfecting his skills in these specific areas.
He has been a Fellow of the American College of Surgeons (FACS) since 2019.
Academically, in addition to a doctoral thesis submitted in 2015, he is the author of more than 30 publications in various fields of surgery and has won numerous awards for his research work.
For several years now, he has also been teaching and supervising a thesis at the University of Geneva's Faculty of Medicine, which awarded him the title of Privat-Docent (Master of Teaching and Research) in 2023.
An expert in the field of obesity surgery, he is a member of the Swiss Society of Bariatric Surgery (SMOB) and the International Society of Bariatric Surgery (IFSO).
For almost 10 years, he has devoted himself to helping patients suffering from obesity by offering them comprehensive care, including both medical and surgical treatments to help them lose weight.
He performs his operations mainly by robotic means.

Dr Pouya Iranmanesh is a specialist in visceral and general surgery, with particular expertise in minimally invasive surgical approaches (laparoscopic and robotic surgery).
His speciality is bariatric surgery. In this context, he works in a multidisciplinary obesity centre and is also authorised to prescribe the latest generation of anti-obesity drugs. His expertise also includes surgery for gastro-oesophageal reflux and hiatal hernia.
In general surgery, he treats pathologies of the gall bladder (including stones), stomach, small intestine and colon, as well as hernias of the abdominal wall (inguinal and umbilical hernias, etc.).
