Where are you today?
You do not need to know which treatment to choose to get started. These entry points help you find your way; your care can then combine several approaches.
I am looking for a solution for my weight
You have already tried to lose weight or you are wondering about possible treatments, including medication.
I am thinking about surgery
Understand the operations, their benefits, their risks and what they involve in daily life.
I have already had surgery
Continue your follow-up or get support if your weight goes back up or if you have difficulties after the operation, including if you were operated on in another hospital, in Switzerland or abroad.
Several approaches, a plan that suits you
Several approaches can complement each other and change with you: nutritional support, physical activity, psychological support according to your needs, medication and surgery.
Psychological support
Explore your relationship with food, with suitable support.
Adapted physical activity
Rediscover the pleasure of moving, at your own pace.
Metabolic and bariatric surgery
When it is indicated, with preparation and follow-up as a team.
Medication and surgery: complementary approaches
Depending on your situation, these treatments can be combined or follow one another within the same care pathway. Their role is discussed with you and reviewed as your follow-up progresses.
Could obesity surgery help you?
It is a recognised option for some people. An assessment consultation helps determine whether it is indicated for you.
What the consultation clarifies
Whether an operation is indicated, which one, with what benefits and risks, and what insurance covers.
Surgical expertise
Dr Pierre Fournier, FMH specialist in surgery, is head of the Department of Surgery at Hôpital de Nyon (GHOL). The team’s operations take place there; the hospital is recognised as a primary centre by the SMOB.
Preparation and follow-up as a team
An assessment adapted to your situation, a decision made collectively with you, then long-term follow-up.
When an operation requires a specialist referral centre, we organise your care in Geneva (HUG), Lausanne or Neuchâtel, depending on your situation. Wherever possible, and with the agreement of the host centre, Dr Pierre Fournier performs your operation there himself.
Understanding your situation before choosing a treatment
Your health is more than a number on the scales.
We first take the time to understand your history, then we set the goals with you.

- Assessing your needsMedical assessment, body composition and other opinions as your situation requires.
- Deciding togetherA decision shared with you; for surgery, a joint decision by the multidisciplinary team.
- Supporting you over timeFollow-up adapted to your needs, in liaison with your GP.
A team of professionals working together for you
