Our Medical Approach
We look at the person –
not only the diagnosis.
Good medicine means understanding connections. We follow a modern, evidence-based concept that is actively developed internationally – particularly in US-American research.
We assess key lifestyle and metabolic factors, evaluate them against current research, and derive individual recommendations and treatment decisions from them.
Goal: improve health sustainably – and meaningfully raise quality of life in chronic conditions.
Sleep
Sleep quality as the foundation of recovery, concentration and long-term health.
Exercise
Physical activity is one of the most effective preventive factors – and often underestimated.
Stress
Systematically identify, classify and specifically reduce chronic stress.
Metabolism
Nutrition, metabolic markers and body composition as levers of health.
Medical Focus Areas
What we offer
Preventive and personalised medicine – with time for detailed analysis, thorough diagnostics and individual decisions.
Preventive Medicine
Structured screening and early detection – with the clear goal of identifying risks before they develop into illness. No waiting for symptoms.
Chronic Conditions
Structured, continuous care for complex conditions – with extended diagnostics, honest assessment and genuine long-term accompaniment.
Extended Diagnostics
Specialised diagnostic procedures and careful evaluation of findings – because precise decisions need a solid foundation.
Individual Therapy Planning
No standard solutions. Every treatment decision is discussed together with you – evidence-based, clearly explained and tailored to your life situation.
Travel & Vaccination Medicine
Individual travel consultation, standard vaccinations and internationally recognised recommendations – for private travel and business trips worldwide.
Pulmonology & Sleep Medicine
Diagnostics and therapy for respiratory and pulmonary conditions and sleep disorders – from Dr. Paul-Georg Behler's clinical experience in the specialist field.
What distinguishes our practice
Time-intensive appointments – not a tick-box exercise, but genuine listening and understanding.
Two specialisms under one roof: General Medicine and Internal Medicine complement each other.
Medicine based on current international research – not just the minimum standard.
Specialisation
Nutritional Medicine
Doctor-medic Diana-Mihaela Behler is a specialist in nutritional medicine. What this means in practice: an individual medical concept, not a standard programme.
Specialist
Nutritional medicine is more than nutritional counselling.
Doctor-medic Behler brings together medical expertise, diagnostic methods and a holistic perspective. The nutritional medicine concept at Praxis Behler includes medical examination, body composition analysis, ultrasound of abdominal organs and individual consultation – billed as a self-pay service (GOÄ).

Billing & Costs
The nutritional medicine concept is a self-pay service billed according to GOÄ. The exact costs depend on the individual scope of services and will be discussed in advance. Laboratory tests, if required, are billed directly by the laboratory.
Who is this suitable for?
The concept is aimed at those who wish to optimise their nutrition and metabolism in a medically supervised way – whether for prevention, existing concerns or as part of a comprehensive health strategy.
Additional Services
Prevention & Self-pay
Some services fall outside statutory health insurance – for good reason: they go deeper than standard permits.
Individual Preventive Medicine
Alongside standard statutory services, we offer individual health and prevention services as self-pay. These include extended diagnostics, detailed risk analyses and nutritional medicine concepts – all billed according to GOÄ, transparently and discussed in advance. If you want to get more out of your health than statutory limits allow, you have come to the right place.
