Obesity is a complex chronic disease whose incidence is constantly rising worldwide. The diagnosis of overweight and obesity is made by calculating the BMI (body mass index) and other additional measurments such as the waist circumference. Our first target is to investigate the causes of the obesity in every patient. There are several causes besides the modern lifestyle (unhealthy diet, sedentary life, stress) such as genetic factors, medications and diseases. Every patient is unique and should be treated as this. Our main goal is to achieve weight loss gradually and with safety as well as to maintain the results over time. The treatment of the obesity is a combination of health and dietary interventions, physical workout and several medications according to the international guidelines. Weight loss is a difficult and ongoing challenge for both the therapist and the patient. Our goal is not only to provide the best medical care but also to support and train every single patient to achieve their target.
