Examine. Understand. Treat.
From findings to treatment.

Understand the connections
We interpret your findings alongside your symptoms, nutrition, sleep and daily demands. Together we decide what to address first.
Put treatment into practice

Your doctor connects
the whole picture.
Jan listens, examines your joints and muscles by hand, and assesses how you move. Bloodwork, body composition and strength measurements add to that picture. He brings the findings together to plan your treatment with you – at the practice, in training and in everyday life.

What patients say.
“Jan Okoye-Weeg is one of the few doctors who really makes you feel seen as a whole person – not just as a patient with a symptom.”

Is this covered by health insurance?
We are a private practice and bill transparently under the German fee schedule for physicians (GOÄ). PKV and Beihilfe reimburse many of our services, though coverage depends on your plan, and some functional diagnostics are self-pay. You'll know what each test costs before we run it.
Which values do you test?
That depends on your history. Typical panels cover micronutrients, thyroid including free values, and inflammation and metabolic markers. We test with purpose, not on suspicion, and you'll know the cost of every test up front.
What does the first appointment look like?
We spend 60 minutes on your symptoms, history and physical examination. You can upload previous results beforehand. Together we decide which further assessments and treatment steps make sense, and discuss scope and costs.
Can I keep seeing my existing doctors?
Yes, absolutely. We are happy to work alongside your existing doctors and specialists, especially when coordination or a second perspective is helpful.
Do I need a referral?
No referral is required. Book directly via Doctolib, or message us if you are unsure which appointment type fits best.
